Roof Repair Tampa, Largo, Clearwater

When you are repairing a roof, or constructing it for the first time, the most important decision you can make is, of course, selecting a proper contractor. But in a close second, is the overwhelming decision on what type of roofing to use. This is because there are so many options to choose from.

You can opt to go the traditional route and get traditional shingles, which provide defense from the elements and resistance to algae. If you are dealing with a flat roof, which may collect rainwater, a low sloped roofing is probably the way to go. Concrete and tile are popular options for aesthetics and give your home a unique appearance. Metal roofs are great and cheap ways to protect your building from the elements. They have a clean appearance and are great for reducing energy use, thanks to the insulation. They can even be claimed for tax credit!

Residential Roofing Repair | 5 Roof Replacement Basics You MUST Know

Residential Roofing Repair | 5 Roof Replacement Basics You MUST Know

Residential Roofing Repair | Within the home remodel workflow, roof replacement is job number one. Every single project you undertake, from drywall installation on down to the most delicate swipe of paint, will be ruined if you do not protect it properly with a roof.

1.  Know:  5 Basic Types of Materials

Your choice of roofing material often depends on your locality, as much as on your own personal taste. Roof pitch affects the kind of rofing shingles you can use!

For example, wood shake shingles can be used for steeper pitched roofs but not low-pitched roofs.

  1. Asphalt composition shingles: Cheap and easily obtainable, but less attractive than other options due to "flat" appearance.
  2. Wood Shake:  Pricey but attractive shingle.
  3. Metal Roofing:  Still rare, and few roofers know how to install it well; special companies are required for this job.
  4. Slate Roofing:  Highly attractive, and a high-end roofing option; extremely slippery to walk on.
  5. Rubber Slate or "Faux" Slate:  Recycled post-industrial synthetics gaining in popularity.

2.  Decide:  Whether To Remove Shingles or Roof Over Them

  • Weight Issues:  The main argument against laying additional layers of asphalt shingles is that the roofing materials can get too heavy for the underlying roof framing.  This can be a structural problem, especially for older houses. It is often said that a triple layer of asphalt shingles is equal to a single layer of slate shingles--an exceedingly heavy type of material.
  • Telegraphing:  One other problem with shingling over existing shingles is that you are essentially repeating some of the surface irregularities that may already be there. If you’re contemplating putting on a new roof, there’s probably a good chance that you may have bubbles, bumps, and waves that you need to get rid of. Putting new shingles over that doesn’t do much for the aesthetic aspect.  One way to minimize this problem is to go over the old roof and correct as many problems as you can. It doesn’t take much more than a hammer, some roofing nails, and a handful of shingles to correct the problem of bumps, gaps, and protruding nails.
  • Saving Work, Reducing Waste:  Stripping off the existing layer and then laying down a new layer adds more work to the process. Not a real problem if roofing professionals are tackling the job—they can strip most roofs in a morning—but if you’re doing the job yourself, it can be rough.

3.  Save: Money and Materials

The cost to replace a roof varies according to your roofing materials, the roofing contractor, the pitch (or steepness) of your roof, the area to be covered, and a host of other factors.

Roofing contractors have a great deal of flexibility to negotiate on the cost, so you please feel that you have license to do so.

4.  Discover: The Best Season For Roofing

A well-coordinated roofing team is amazing--and this is why we pay them to do our roofs.  If roofers only wanted for perfect conditions to install a roof, they would go out of business.  Extending work seasons helps roofers and consumers alike.

In most parts of the U.S., though, optimal roofing season is from late spring to early fall.  

Partially installed areas must be perfectly dry before any covering layers are installed. The trick behind "expertly shoehorning" in the roofing project is having a large team of professional roofers who can knock out work in hours, instead of days, thus taking advantage of dry periods in off seasons.

5.  Understand: The Basic Process of Roofing

The word "square," when used in relation to roofing, means 100 square feet. 

One reason why roofers speak in terms of squares is because they deal with such vast quantities of materials.  It is pointless to discuss smaller units.

Residential Roofing | Introduction to Asphalt Shingles

Residential Roofing | Introduction to Asphalt Shingles

Residential Roofing | There are many types of shingles that are used with a sloping roof including:

  • Asphalt shingles
  • Tile roofing shingles (clay or concrete)
  • Slate shingles
  • Wood shingles and shakes
  • Metal shingles

But of all these material types, the overwhelmingly most popular, versatile, simple to install and cost effective choice is the asphalt shingle roof.

First used in 1901, asphalt shingles have been part of the American home landscape for over a century. These shingles are durable for the price, affordable and come in many different textures and colors. The most common styles of asphalt shingles are the "strip" shingle or the "laminated" shingle.

Although fairly durable, asphalt shingles are still subject to damage  and your roof should be checked after major hail or wind storms. Additionally, you should always make sure that your roof ventalation. 

According to a 2007 study by IWCS, about 11 million tons of asphalt shingle waste is generated annually in the US.

Shingle waste comes mostly from new or replacement roof installations which can cost several thousands of dollars according to

OK, let's take a look at some basics related to asphalt shingles.

Types of Asphalt Shingle Construction

The most common type of asphalt shingle homeowners will have installed are either fiberglass shingles or organic mat-based shingles. The shingle will have either an asphalt saturated organic substrate made from cellulose fibers like wood or paper, or it can have a fiberglass based substrate or mat.

Fiberglass shingles can have these general characteristics:

  • High durability and strength
  • Lighter weight and thinner material
  • Higher fire rating than organic varieties
  • Longer warranties

Organic mat shingles can have 40 percent or more asphalt content than fiberglass which makes them heavier, thicker and more expensive. However, they are also rugged, flexible and able to absorb more damage over time.

The weathering side of the shingle is coated with a harder asphalt material and then embedded with special aggregate granules for a weathering surface.  A heat sensitive adhesive or "self sealing strip" of mastic is then applied above the tabs so the shingles adhere to each other once nailed in place in a staggered manner.

Design Options With Asphalt Shingles
Shingles come in different basic design styles including the old standby three-tab strip shingle and the more textural dimensional laminated architectural shingle.

  • The strip shingle is a basic shingle with a strip of material (usually 3 times the length to height in proportion) with cutouts or tabs. The most common strip shingle is the 3-tab strip shingle.
  • The laminated dimensional shingle is a premium shingle and has multiple layers of tabs to create a texture and dimension to the shingle. A variation of the dimensional shingle is the luxury shingle which is much thicker and has larger exposures than dimensional shingles. Luxury shingles can mimic the appearance of wood or slate shingles.

Three-tab shingles have cutouts or tabs that are lined along their lower edges. This means that each shingle looks like three different pieces, but they’re actually one large piece. This type of shingle design remains the most popular and economical means of covering a roof today because it covers more ground.

In comparison, laminated dimensional shingles have no cutouts but rather portions that are laminated with more asphalt. The sealant of asphalt bonds their layers, which reinforces their ability to defend against impact damage, rain and wind.

Asphalt shingles are designed for roof slopes of at least a 4:12 pitch (4 inch vertical rise over a 12 inch horizontal run). Between 2:12 and 4:12 some manufactures may allow their product to be used if installed according to their special instructions. Never install asphalt shingles on roof slopes less than 2:12.

Asphalt Shingle Colors
Apart from the different asphalt shingle varieties and designs, there’s also no shortage of colors to choose from to put on your roof. The color choices have expanded since the inception of asphalt shingles, and your choices depend on what you want for your home and what matches its style.

Some of the tones will range from gray to red to brown, and you’ll find blue and green mixed in as well. You can also mix light and dark tones together to create weathered or vintage shingles for older homes. Roofing professionals have access to new technology that allows you to experiment with colors on your home through an online tool before installing them on your home.

Energy Efficient Shingles
For those homeowners who want to move towards green and energy efficient homes, many manufacturers in the industry are starting to produce energy efficient asphalt shingles. Using cool-roof technology, asphalt shingles are now being designed to absorb less heat from the sun. This cuts down on how much your air conditioner has to turn on during those hot summer days.

Roofing Contractor | Pros and Cons of Tile Roofing

Roofing Contractor | Pros and Cons of Tile Roofing

Roofing Contractor | Tiled roofs are beautiful and durable. They are also expensive and heavy but that is just the nature of a building material that will last upwards of 100 years. Tile roofing is usually made from Concrete Roofing Tiles or Clay Roofing Tiles and can come in shapes such as curved, flat / interlocking or fluted.

Tile roofing is a great choice for roofs that experience hot weather or exposure to salt air. You will see tiled roofs most often in arid areas such as the southwest, and coastal areas like southern Florida or California. If you’re considering tile roofing for your home, be aware that these roofing systems are heavy and can break under certain conditions.

Pros of Tile Roofing

There are many advantages to installing tile roofing regardless of which material you choose. Some of these advantages include:


A tile roof can last over 100 years, especially when installed in the right climate

Clay and concrete tile roofs have been known to withstand hail, high winds and even fires. Once you install tile, you will never have to install another type of roofing again. Just in case, manufacturers will offer a 50-year warranty.

Plenty of choices

Clay, concrete and slate tiles come in a wide variety of colors and styles, so your home will match the roofing. They give it a distinct Spanish or Southwestern look, depending on what you’re going for. These tiles have been known to match home styles like contemporary, European, colonial or historical. You can find them looking flat, round, in the style of wood shake roofing, or even as if they came from centuries-old homes.

More advantages to tile roofing include:

  • Impervious to fire damage
  • Resistant to physical impact damage 
  • Can resist any kind of environmental, rot or insect damage
  • Withstands rain, snow or freezing/thawing weather without any damage
  • Environmentally friendly and can be recycled
  • Regulates the indoor temperature of your home because of the tile's thermal mass
  • Requires virtually no maintenance

Cons of Tile Roofing

There are some disadvantages to installing tile roofing. For those who are budget-conscious the initial cost is one factor to consider. A clay tile roof system can cost two to three times the cost of an asphalt roofing system. A clay tile roof can cost between $675 to $1400 per square (100 SF of roof area). Concrete tile roofs are more economical and cost $400 to $450 per square.


Installing tile roofing absolutely requires professional roofing contractors like you will find at Home Advisors. The tiles will need to be measured, laid in a specific pattern and checked so that no moisture gets through. This is not a DIY project.

They’re Heavy

Weight is another factor. Your roof structure must be able to handle the weight of a tile roof which can weigh about 850 pounds per square for clay tile and 950 pounds per square for concrete tile. An asphalt roofing by comparison weighs around 225 to 325 pounds per square.

If you’re reroofing and replacing shingle roofing with tiles, you’ll need to hire an engineer in addition to a roofing pro to figure out where the structural reinforcement goes. You’ll be spending additional funds on the reinforcements to handle the weight of the tiles.

Other disadvantages of tile roofing are:

  • Material is fragile and can break during storms or inspections
  • Not usable for roof pitches below 4:12
  • Takes a longer time to install than asphalt roofing. Be ready for additional time and labor costs.

Roofing Repair | Safety: Installing Roofing

Roofing Repair | Safety: Installing Roofing

Roofing Repair | Safety: Installing Roofing

Roof installation has several safety requirements that you must comply to not only save the life of your workers, but to also avoid being fined by OSHA. Safety is of considerable concern for a home builder when installing roof trussel and components. The majority of US residential construction is composed of wooden roof trusses that require workers leaving a stable platform to work on different heights.

Safety Methods When Installing Roof Trusses

Numerous methods can be used to prevent fall-related injuries and fatalities among workers installing roof trusses.

  • Ladders
  • One small accessory can provide your worker with great safety and if used properly can avoid a huge fine by OSHA. Either ladders or steps can be used to ensure the safety of the employee and will provide a stable platform to work while installing roof trusses.

  • Bracket Scaffold
  • Roof truss installation may require work from an elevated or suspended platform. A bracket scaffold placed on the exterior or interior of your building will provide a safe work area for your workers. When the bracket scaffold is used on the interior of the building, the outer walls can serve as a safety constrain that can reduce the falling hazard. If the bracket scaffold if placed on the outside of the building, your workers can perform on a more visible area and certain additions can be added to provide a safe area to work. When using the bracket scaffold on the exterior, the guardrail system can protect and provide fall protection. Toe boards are necessary to prevent falling objects that can risk other workers’ safety when installing roof trusses.

    • Anchors
    • Anchors are commonly used devices which provide safety when installing roof trusses or when working over roof surfaces. Arrest forces are distributed across wood trusses when anchor systems are used, and spreaders can act as anchors providing personal fall arrest system protection and fall restraint. One critical advantage of anchors and spreaders is their design to withstand exerted forces upon them and over wood trusses. A structural engineer can be consulted to determine the capacity and strength requirement on each particular situation.

      Safety Methods When Installing Rafters

    • Anchors
    • When your workers are installing rafters on roof areas, anchors are the best solution to provide a safe work area. Using strap anchors or bolt-on anchors, combined with personal fall arrest systems, is the best combination for your workers.

      Safety Methods When Installing Sheathing

      Roof sheathing activities are one of the most hazardous activities to perform in the construction industry.

    • Safety Net
    • After the roof has been framed the sheathing activity starts. Workers will be working on elevated areas and risk of injury mitigated by installing safety nets below the work areas. As for the anchor systems, when using safety nets as fall protection systems, proper design must be performed to allow it to withstand the impact of the falling worker.

    • Bracket Scaffold
    • The bracket scaffold can be attached to the top of the structure to provide a safe and stable platform to complete the roof sheathing activity. Be aware that proper scaffolding should be installed by carefully-selected and trained workers with experience in scaffolding set-up.

    • Retractable Lifeline
    • Using retractable lifeline stands is the best alternative for workers when installing roof sheathing.

      Safety Methods When Performing Roofing Jobs

    • Anchors
    • Using strap anchors or bolt-on anchors can be the difference between the life and death of your worker. Both anchors can be used throughout construction for a variety of activities, not only on roofing jobs. Anchors and their condition must be carefully inspected prior to use and if there is any signal of wear, they must be discarded.

    • Bracket Scaffolds

    Bracket scaffolding can also be used to provide a safe work area for employees on elevated areas.

Roofing Contractor | How Do I Maintain My Metal Roof System?

Roofing Contractor | How Do I Maintain My Metal Roof System?

Roofing Contractor | There are many different types of roof systems used on homes and buildings. Some are considered more traditional and commonplace such as asphalt shingles. 

One type of roof system that has a very long life expectancy and has been used for centuries to provide homes and buildings with a sound roof system is metal. Metal roof systems provide a long life expectancy if they are properly installed and subsequently maintained after their installation. As with all types of roof systems, the key to a long service life is periodic maintenance and repairs. Without the proper maintenance any roof system will begin to fail. There are several key characteristics of metal roof systems that must be determined prior to implementing an effective maintenance program.

Architectural versus Structural

Metal roof systems are grouped into two primary system types. These system types are important to understand so that the maintenance program and necessary repairs can be properly designed to help extend the life of the roof system.

The first type of metal roof system is an architectural metal roof. Architectural metal roof systems are metal roofs that are used to provide the waterproofing layer to the roof system of the structure. In addition to providing the protective waterproof layer, they normally can provide an aesthetic appearance to the structure as well.

The second type of metal roof system is a structural metal roof. Structural metal roof systems are metal roofs that act as both the roof deck as well as the waterproofing layer for the building. An example of this type of roof can be found on a barn where the underside of the metal roof may be visible from the interior of the structure. Some commercial buildings also use a structural metal roof system as part of their building envelope.

It is important to consider this characteristic before you address the maintenance for your roof system. There are several reasons; however an important reason to consider this feature is associated with safety. If the structural metal roof system shows signs of deterioration this may be a safety hazard for someone attempting to gain access to the roof. Since the roof system acts as the roof deck, any deterioration that has occurred to the roof system can lead to a compromised roof deck and create a hazard for someone accessing the roof.

Metal Type

It is not only important to consider whether you have a structural metal roof system or an architectural metal roof system, but also you must consider what type of metal has been used to construct your roof system. There are many different types of metal used to manufacture metal roof systems. These can include steel, aluminum, copper and tin. There are other unique metal types including zinc and lead coated copper.

It is important to determine the type of metal used as part of your roof system because the type of metal determines the proper methods of repair and maintenance to your roof. For example, if you have a metal roof system that was installed using copper, the proper method of repair may be to use solder to repair the roof system.

Methods used to maintain your roof system are also determined by the type of metal used to install the roof system. Some metal roof systems are comprised of steel panels. Steel is prone to rusting and oxidation. As a result, if your metal roof system is steel it is recommended that the roof system is reviewed routinely for rust and any rusting conditions be addressed as soon as they are discovered. In addition, rusting and oxidation on steel must be treated with a rust inhibitor before they are coated to prevent the rust from spreading.

System Design

The final characteristic that should be considered is the system design. There are multiple configurations of metal roof systems. Each configuration has different methods of repair and maintenance. Metal roof systems may be installed using flat seam panels, metal roof shingles, standing steam metal or interlocking panels.

The system design impacts how the roof system is repaired and maintained. If damages occur to a metal roof system, the configuration of the system will impact how the homeowner or professional roofing contractor will repair that system.

The system design also impacts how the roof system is maintained. Maintenance of metal roof systems may incorporate cleaning the roof system prior to repair or a maintenance coating. Flat seamed metal roof panels with soldered seams may be able to pressure washed before they are coated, but a metal roof system that incorporates metal roof shingles cannot be pressure washed because they are designed to shed water.


As the old saying goes, "The Devil Is In The Details". This saying is a great reminder with regards to metal roof systems. If you overlook the details of your metal roof system, the choices that are made regarding how to maintain or repair the roof system can cause more damage to the roof system that what you are attempting to repair. It is important to consider these characteristics in advance so that you can plan the maintenance and repairs for your roof and maximize the life expectancy of your roof.

Roofing Repair | Tips for Cleaning and Repairing Gutters

Roofing Repair | Tips for Cleaning and Repairing Gutters

Roofing Repair | 

  • There are just a few steps to follow in order to maintain gutters. First, climb a ladder and clean the goop out of the gutters. The decomposed leaves make great mulch or compost. Pay particular attention to the downspout. If leaves and debris are clogging it, water won't drain properly, and along with mildew and mud you'll end up with sagging gutters.
  • Check all the spikes that are supposed to go through the gutter, through the fascia board and into the rafter behind it. At most homes, these spikes miss the rafters entirely, usually because the spike has just worked its way out of the hole over the years. It's a good idea to invest in new gutter spikes so the gutters are securely fastened once again.
  • Another thing you want to look at are the sources of any leaks, including holes in the gutters and cracked caulking in the seams. Use an old chisel to scrape the old caulking out and dry the area thoroughly. Then use new bead silicon sealing to keep water from getting down behind the gutters and rotting the boards.
  • During this inspection, check out the rivets on the downspout. Frequently they'll be loose or will have dropped out completely, all that is needed is a rivet gun to secure them anew.
  • Guide:
  • A pressure washer won't hurt the gutters provided you've secured the gutters with screws or new spikes. The real key is to avoid hitting the gutters at too high an angle or you'll blow the shingles off with a high-pressure stream of water.
  • If the gutters are rusting, they are very old. They've moved to aluminum and vinyl gutters now, and they don't rust. You might want to consider new gutters. But if you're going to stay with the old ones, get all the rust off, sand them down, paint them with a good primer and then with a good-quality rust-inhibiting paint.
  • A splash block is a very important element. It keeps the water coming out of the downspouts from digging a trench next to the house, and it keeps water away from the home's foundation.

Here are some bonus tips when replacing gutter spikes:

  • Remove the old gutter spikes and ferrules (the large spacers that keep the gutter walls from collapsing while you drill), installing each new set as soon as you remove the old one.
  • Position the new ferrule inside the gutter, directly behind the existing spike hole.
  • Insert the gutter screw into the existing spike hole. Use a standard variable-speed drill, electric or cordless, to slowly thread the fastener through the spike hole and the ferrule and then into the existing fascia hole.
  • Thread the fastener until the head is even with the gutter and the screw has engaged with the rafters on the other side of the fascia board. Do not hesitate to call your trusted roofing repair company -PHI Roofs. Serviing Pinellas/Pasco, Hillsborough and Sarasota/Manatee county. -DIY

Residential Roofing | Top 10 Roofing Tips

Residential Roofing | Top 10 Roofing Tips

Residential Roofing |  Think Safety First

Living in St. Petersburg, Fl -Fussing to try and find a leak as soon as it happens is something that could put you in the hospital. Meddling on a roof while it's raining isn't the ideal way to find a leak. Trying to temporarily fix a leak could be highly dangerous. If you want to do it right, there is no quick-fix. Just take your time, and be very patient and careful to wait for Mother Nature to give you the green light.

Take Precautions

Being on a roof will put the body in positions that are not comfortable or safe. Make sure to wear rubber sole shoes to prevent slipping. Also use a harness and always work with a buddy.

Spray the Roof

Take a garden hose and go up to the roof and start spraying in different locations to find the leak. Wait if it's wintertime because it's not safe to run water on the roof when it's freezing out.

Keep Gutters Clean

One of the most common areas and causes for roof leaks are clogged gutters. Gutters that have not been cleaned can cause the water to build up during rain.

Avoid Dry Rot

Dry rot isn't related to any type of water damage, but lack of ventilation. If a roof repair is right in the middle of the roof, there is a chance that the plywood might be deteriorating. The roof will actually sag in and cause the roof shingles to get brittle, crack and then leak. Preventing dry rot consists of installing a ridge vent, which will only work if there is a soffit vent. Holes have to be drilled through the soffit vents so cool air comes in through the bottom and pushes the hot air out through the top.

Fix Roof Boots

Flashing, roofing, ice damping and skylights are all obvious places for potential leaks. One thing people often miss is the rubber boots. It's where the roof fence comes up that you find roof boots. If they dry up they will cause major leaks. It's a quick fix; purchase a new roof boot in a local hardware store. You may have to remove some of the shingles, lay a better tar under it and put it back in place.

Inspect Materials

Sometimes shingles are faulty and will begin to crack after they've been nailed down. Faulty installation with nails and shingles can also play a big part in leaks. Nails could be nailed too low and it will start pushing back up. Make sure to always check merchandise before getting on the roof.

Check Valleys

A valley is where the intersection of two roofs comes together. It is also called the ridge, which is again where two roofs meet at the top. Valleys are very common places for leaks because that's where the water from the entire roof goes to and it will start sloshing back and forth.

Eliminate Leaks

It's important not to get discouraged when a leak can't be found. It's a process of elimination. You've covered one area, installed the shingles back and sealed it watertight so at least one spot is eliminated. Now, you can try other areas. -DIY

Roofing Contractor | Types of Roof Drains

Roofing Contractor | Types of Roof Drains

Roofing Contractor | Roof drains are now a combination of functionality and modern aesthetics, were water will be carried away from the surface being protected. A roof drain installed with the wrong size of pipe, will not be as useful as expected and sometimes it will generate even more problems than the one it is supposed to solve. When roof drains are designed and install properly, they will maintain your area free of water only if they are maintained on a regular basis. Roof drains come in different shapes, sizes, and will vary on the roof and building where they will be installed. Before deciding which roof drain to use, consider the roof size, pitch, drain location, inflow rate, safety requirements and rainfall volume.

How to Size Your Roof Drain

Your roof shall be equally spaced and located in low points of the roof or in any area on which water is accumulated has been identified. To determine your roof drain size first you need to calculate the roof area or surface area that the drains will be covering.

The next important thing that you must know is the average hourly rainfall rate at the location where the project is located. There is plenty of information from which you can obtain this information. Pick a leader (drain pipe) size, the larger the pipe the fewer the roof drains needed. Now you must determine the roof area drained by each leader. This information could be obtained from the pipe of drain manufacturer. Divide the roof area by the area per each leader to determine the number of drains required.

How to Choose the Right Roof Drain

To choose the right roof drain; you must consider the following factors:

  • Type of roof
  • Roof Pitch
  • Volume of average rainfall and storm design criteria (100 years, 50 years, 25 years and so on), normally set by your local building code.
  • Rate of drainage
  • Overflow requirements from local or state building code
  • Roof load (how much water does the roof can hold up if the drains are obstructed). This is really important as too much water could affect the structural stability of the roof.
  • Drain locations
  • Drain sizing
  • Additional features such as vandal proof and others

Flat Roof Drain

The ideal drain if your structure has a flat roof is a flat roof frame, designed to flow part full. This type of drain could be installed in flat or almost flat roof with less than a 2% slope. The drain will be connected to rain gutters and will help divert the water away from the structure. It is recommended that you install a flat roof drain with covers, to prevent debris and other potential obstruction elements get into the drain or the gutter.

Siphonic Roof Drain

A siphonic roof drain is designed to operate at full capacity, when water is vacuumed from the roof into the drain at higher velocities when compared to flat drains. These roof drains allow the designer to install a minimal number of roof drains and have them connected into a single rain leader. The siphonic roof drain incorporates a mechanism that allows water drain faster than using any other roof drain. It normally cost more than a regular roof drain but it works smoothly and reduces the need for maintenance. This type of drain could be connected using horizontal rain leaders instead of having sloped or downward pipes.

Green Roof Drains

The new trend in roof drains is to replace the traditional roof with a Green roof. Green roofs will reduce noise transmission, reduce heat inside the building, and improve air quality. A green roof drainage system will be designed to accommodate drainage while protecting the building structure with heavy waterproofing membranes. Two types of green roof exist: intensive and extensive.

Residential Roofing | The Key to Long-term Roof System Performance

Residential Roofing | The Key to Long-term Roof System Performance

Residential Roofing | Roofing professionals generally agree a good roof system requires proper design, quality materials and quality application to perform successfully. Yet once the roof system is installed, nothing is more critical to its long-term performance than establishing a program of regular inspections and proper maintenance. The National Roofing Contractors Association (NRCA) believes the most effective way to achieve long-term roof system performance is for a building owner to have a formal, long-term relationship with an NRCA-member professional roofing contractor. An NRCA-member professional roofing contractor:

• Understands local building practices

• Understands different roof systems and can make recommendations concerning which type of system is best for a particular building

• Has a trained and experienced work force that knows how to complete the work • Can respond quickly if a problem arises

• Is well-established in the community, so the owner understands with whom he or she is working • Works in, and gives back to, his or her local community

• Understands the local business environment NRCA has expressed concerns regarding the long-term warranties offered by many roofing material manufacturers because warranties do not necessarily provide assurance of satisfactory roof system performance. Warranties often contain provisions that significantly limit the warrantor’s liability and the consumer’s remedies in the event problems develop or damage occurs to the roof system. Instead, NRCA believes the best way for a building owner to ensure satisfactory post-installation roof system performance is to have a formal, long-term maintenance agreement with an NRCA-member professional roofing contractor. Maintenance programs typically offer the following advantages:

• A maintenance program is proactive (rather than reactive). It can help to identify problems at their early stages when they can be corrected and before they become catastrophes.

• Regular maintenance can reveal and address sources and causes of leaks before they occur. Too many owners have their roof systems examined only after a leak occurs.

• A maintenance program allows for a planned, organized approach to management of a roof asset and allows for responsible, timely preparation of long-term capital expenditures.

• Response time to address leakage problems is greatly improved. Warranty repairs, on the other hand, can take time to be processed while the problem remains unresolved. Building owners should take care in selecting a roofing contractor to perform maintenance work. Additional information is available from NRCA or from an NRCA-member professional roofing contractor in your area. NRCA, a nonprofit trade association, is one of the construction industry’s most respected organizations and the voice and leading authority in the roofing industry for information, education, technology and advocacy.

Roofing Repair | Flat Mobile Home Roof Repair

Roofing Repair | Flat Mobile Home Roof Repair

Roofing Repair |  Water is the most damaging force on earth and your roof is the first shield of defense against it. Proper maintenance can help a lot, but even the most well-maintained roofs will eventually begin leaking. Nothing lasts forever!  

Mobile homes, especially older models, have a different type of roof structure. Knowing the types of roofing, and how to best repair leaks, can save a lot of money and frustration. we'll go over the three main types of roofing and finish 

3 Types of Roof 

Mobile and manufactured homes roofs have been built with 3 basic shapes through the years. Mobile homes (which are built before June 1976) typically have flat, or bowstring trusses, that are covered with metal or asphalt.

Newer manufactured homes will have standard trusses, these are also called a peaked or pitched roof, and are covered with shingles. Double wide roofs use half trusses that become a single standard truss once setup. 

Coating Metal Roofs 

If your roof is bowstring or flat, it may have came with a metal roof. You are supposed to coat these roofs every couple of years or so, based on the manufacturer's recommendations. 

There are misunderstandings about sealing a mobile home roof. Most people think sealing the roof will repair leaks, but that's not really the case. 

Sealing a metal roof helps do two things: provide a reflective surface so the sun's rays are reflected and preventing the metal from rusting. While it will help seal small leaks, it's won't last because it's not made for repairing leaks. 

Before sealing, you will need to prepare the roof properly. You can't just go up there and throw seal on it! The surface has to be clean and scrapped smooth. Previous coats on seams and vents need to be removed with a grinder or steel brush. You want the new coating to bond well.

After cleaning the surface, and before adding yet another coat in an attempt to fix a leak, you need to find the problem areas and seal them. 

Most mobile home repair professionals recommend a neoprene or polyurethane flashing sealant. Add it to the seams and around the vents and let it cure. Be sure to use the manufacturers instruction. 

Once the flashing has cured you will add the coating. White elastrometric coating is recommended. Follow manufacturers directions.

Install a New Roof

Another way to deal with a flat roof leak is to replace the roof or re-roof the home. Everyone has to re-roof their home eventually. 

There's many types of roof replacement systems. Here's the top three:

Seamless Rubber Roof

A seamless rubber roof is basically a thick coating of liquid rubber poured on the roof. Before the product is applied, the seams and vent flashing are sealed with a rubber neoprene product. 

Seamed rubber roofs are sheets of rubber stretched over the roof. These are very popular roofing replacement and repair options for RVs but larger mobile homes will likely need to be seamed together. The rubber comes in various thicknesses.

The rubber is cut to have enough room to fall off the side of the roof a bit so that a termination bar can hold it in place. 

Corrugated Metal Roof

If sealing and rubber is something you don't want to be involved with, a metal roof is the best option for you.

The basic installation method is fairly simple and the overall cost of a metal roof is affordable. Most homeowners will opt to hire someone to install a metal roof.

Roofing Contractor | 5 DIY Roof Repair Tips

Roofing Contractor | 5 DIY Roof Repair Tips

Roofing Contractor | 

If your roof is in need of some repairs and you’re looking to save a little money, you may want to look into doing some of the work yourself. While not a replacement for a professional reroofing job, some small jobs can be undertaken by DIY homeowners who don’t mind heights.

Types of Roof Repair

There are several factors that go into roof repair. Before you take on a DIY roof repair job, keep in mind that not every problem is as straightforward as it seems. What may seem like a simple job of replacing a few shingles could be just patching and disguising a more invasive problem that needs professional help. If you aren’t sure that what you are tackling is the full extent of the problem, make sure you call for a free professional inspection and quote before you begin the DIY roof repair project.

Shingle Replacement

If you just have a few missing or damaged shingles, and the problem is localized to one area of the roof, it may be possible to just replace those few shingles. The key is to find new shingles that match the ones on your roof both in style and in color. Patches can be very obvious if they aren’t matched correctly, and this can detract from curb appeal, potentially losing the confidence of new buyers.

You’ll want to remove the old shingles completely and potentially the ones surrounding them if they’re also loose. Use a combination of adhesives made for those shingles and nails to secure them in place.

Partial Reroofing

A partial reroofing involves the removal of all the shingles on an area of the roof, and the replacement of new ones. Occasionally, it can also mean just layering on new shingles over the entire area. This makes patches less obvious if you were unable to get an exact match to what’s already on the roof.

Keep a few things in mind though:

You can only layer shingles once; if you already have two layers on there, you need to remove them both.

If you do remove two layers of shingles, or layer on top of a single layer, your new section may not join up with the other sections of the roof. This could cause a hump at the ridge cap, or some strange looking lines that can detract from the curb appeal. You could also find yourself attempting to match things up with extra layers at the top, and trying to even things out after the fact.

A partial reroofing is a good way to go, however, if you have a large section of shingles that are missing or damaged, but the rest of the roof is in good shape.

Total Reroofing

If the damage to your roof is widespread, or you have localized areas that need repair and the entire roof is reaching its age limit, it may be the right move to reroof the whole thing. This will involve potentially stripping off the old shingles before applying new ones.

The benefits of this are that newer shingles adhere better than older varieties, and by stripping off the old shingles, you can get better coverage. Keep in mind, that you can potentially save labor by layering one set of new shingles over the old ones provided that there is only one existing layer. If you’re already at two layers, be sure to take it all the way down to the roof deck.


Sometimes what really needs to be repaired on the roof is not the shingles, but the flashing. Additionally, any time that you reroof or partially reroof you should also replace the flashing as well as a part of the DIY roof repair. The flashing is located around the chimneys, skylights, and other areas where there is a gap in the roof. Loose, damaged, or missing flashing could be responsible for leaks and other issues in the home.

Tips for Minor DIY Roof Repair

Major repairs and reroofing jobs should ideally be left to the professionals whenever possible. They can help ensure that the job gets done correctly, and in a timely manner.

Smaller DIY roof repair jobs, though, can usually be carried out by do-it-yourself homeowners without too much of a problem. Use some of these tips to make the job easier:

  • Wear rubber soled shoes to help get good traction when doing the diy roof repair.
  • Discard and replace any shingles that come completely loose or free from the roof.
  • Flatten out curling shingles and re-adhere their edges to the roof with some caulk or roofing adhesive.
  • Soften brittle curled shingles with a heat gun first to avoid breaking them.
  • Make sure the back edge of the new shingles slide under the row of shingles behind them, and the front edges line up with the shingles on either side.
  • Fasten the top of each new shingle with 6d galvanized roofing nails, and cover the tops of each nail head with roof cement. Spread the same cement beneath the rest of the shingle to help hold it in place.
  • Fill the joints around your flashing with roof cement to make sure that they are properly sealed.
  • Apply extra roof cement with a putty knife to any seam that appears to be cracked or worn.

Keep Your Roof in Good Repair

Remember to take care of problems as soon as you spot them, either by undertaking some DIY roof repair or by calling a professional. If the problem appears to be widespread, it probably means it’s time for a new roof, and your best bet is probably to call for a free quote and inspection first, rather than attempting to repair it yourself. Keep your roof in good repair and know that your home is well protected from the elements.

Roofing Repair | How to Do a Quick Semi-Annual Visual Roof Inspection

Roofing Repair | How to Do a Quick Semi-Annual Visual Roof Inspection

Roofing Repair | It's the roof's job to literally take a beating. Environmental changes of temperature, rain, ultraviolet radiation, damp shade, wet leaves and any number of factors can take their toll on roofing such as asphalt shingles. Twice a year such as in the Spring and Fall it is a good idea to walk the roof and make a visual inspection of its condition. You can of course try to gauge condition from the ground using binoculars but better results will happen if you get up on the roof and walk it.

Please note that whenever using a ladder to access the roof you should know and apply ladder safety.

Here are some key areas to evaluate when making a visual roof inspection. You'll want to check the main roof components involvingshingles, flashing and gutters.

Check the Roof Shingles:

  • Check the condition of your roofs shingles. Damaged shingles that are loose, curled, blistered, broken or even missing need to be repaired quickly. Carefully lift a shingle and make sure you see roofing underlayment between the shingles and the roof decking. If this critical underlayment is missing the roof has been installed improperly and needs replacement. Without underlayment water damage will continue to occur in your home and to the roof shingles.
  • Shingles that curl up or down do it as a result of being improper installed, due to environmental conditions or age.
  • Buckling shingles are usually caused by lack of roofing underlayment.
  • Cracked or bent shingles often occur as a result of weather conditions, age and general wear.
  • Roof shingles disintegrating from age is a serious problem requiring roof replacement.

  • Check the ridge shingles for cracks or failure. Leakage here can present itself anyplace inside your home.

  • Shingles missing or damaged from wind, hail or impact or other causes of environmental roof damage such as moss will need to be replaced.
  • Check for granular erosion of the roof shingles. This is a sign of deterioration and will require new roof shingles soon.

Check the Roof Flashing:

  • Check the roof valleys (where two different roof planes meet) for cracked roofing, holes in any patches or failure of any metal valley flashing. Valleys are particularly vulnerable to leaks.
  • Check for roof flashing damage in step flashing at walls and around chimneys. Make sure there are no gaps between the flashing and the wall.
  • Check for flashing damage around roof penetrations such as vent pipes. They should be tight, sealed with a flashing boot and pliable caulking or bituminous roofing cement. Be on the lookout for a missing rubber flashing boot, improperly installed flashing boot such as the metal base  of the flashing boot isn't covered by shingles at the sides and above the stack, overall flashing damage, visible nail heads securing the boot flashing to the roof deck, the boot is coated with dried and cracked roof cement.

Check the Roof Gutters:

  • A tell tale sign of granular erosion of asphalt roofing shingles is finding lots of tiny roof granules in the gutters. This is a sign of age and deterioration.
  • make sure the gutter and downspout system is cleaned out and functioning properly. If the guttering does not work and is clogged, water can build up under lower edge roof shingles and also drain behind the gutter and rot the fascia boards.

Residential Roofing | Tips for Evaluating Roof and Flashing Leaks

Residential Roofing | Tips for Evaluating Roof and Flashing Leaks

b2ap3 thumbnail rain 432770 1280
Residential Roofing | If you have ever had a roof leak you know how frustrating it can be to try and find the source of the leak. More often than not you will find that the leak is due to a problem with flashing. As you can see in the photo, flashing problems (usually due to improper installation) can cause serious damage. Unfortunately, this damage is often hidden until it becomes severe. In this article I've asked Michael Chotiner who works for Home Depot to weigh in on some summarized tips to consider when inspecting asphalt shingle roofs for leaks.

Joints between the roof deck and any feature that changes or interrupts the roof slope need flashing. A large majority of roof leaks are caused by missing, improperly installed or failed flashing in the following areas:

The most effective protection for joints where a chimney passes through a roof deck are joints crafted with sheet metal step flashing. There are a number of good ways to construct chimney flashing, and all require skilled craftsmanship.

But even the best are vulnerable to weathering, freeze-thaw cycles, normal expansion and contraction caused by temperature fluctuations, and settling or sagging of a house foundation and roof structure. If you see evidence that a leak has its origin from a point high up on a roof-that is, if water stains appear on ceilings well away from exterior walls-suspect the chimney flashing. A chimney flashing probably needs replacement or repair if:

Visible metal is bent or twisted;
The sheet metal isn't in continuous contact with the chimney;
There are signs of rust or other oxidation;
Roof cement or caulk has been applied over the metal flashing, especially if it's dried and/or cracked;
If you find loose brick or bad mortar joints in a masonry chimney, they may also be the source of leaks.

Vent Stacks:
Plumbing vents that come up through a roof deck should be protected with sheet metal / rubber boot flashing with a bead of roof cement applied at the top joint where the flashing meets the pipe. The source of a leak could be around the vent stack penetrating the roof if:

A flashing boot isn't present;
The flashing material is damaged;
The flashing / boot assembly hasn't been properly installed-for example, if the metal base isn't covered by shingles at the sides and above the stack
Nail heads securing the boot flashing to the roof deck are visible
The boot is coated with roof cement or caulk, particularly if the coating is dried and/or cracked

Roof Valley:
Joints where two different roof planes meet are particularly vulnerable to leaks. There are a number of acceptable ways to flash valleys on asphalt shingle roofs, including applying extra layers of felt underlayment or a layer of self-adhering asphalt membrane where the roof planes join. Valley construction without flashing will use asphalt shingles from each of the adjoining roof planes. They are applied over the underlayment and run past the joint, overlapping to provide extra layers of protection.

A much better approach is to place a wide strip of sheet metal flashing over underlayment at the valley joint; shingles from the adjoining roof planes are trimmed so that a swath of metal is exposed. Unless the valley flashing is the open metal type, it may be a little difficult to tell how a valley was flashed without removing a few shingles and investigating.

Roof valley flashing may be the source of a leak if the leak appears in proximity below a valley. Here are a few conditions that might cause problems:

Flashing underlayment was not adequately overlapped-lower sheets should be overlapped by higher sheets at least 12 in. at the top and 8 in. along the sides
Underlayment was nailed too close to the joint of the roof sheathing-should be at least 8 in. from valley center.
Buckled or otherwise damaged metal flashing

Dormers / Adjoining Sidewalls:
Joints between a sloping roof deck and a vertical surface such as a house wall, dormer sidewall or chimney should be protected with metal step flashing. Some roof shingles and siding may need to be removed to inspect the flashing.

Flashing at the Eaves:
In cold winter climates you will find that leaks occurring within 2 feet or so of exterior walls are usually caused by inadequate eave flashing. This condition is exacerbated by inadequate roof ventilation which together can cause serious ice dam damage. To protect against leaks caused by ice dams, roof sheathing should be waterproofed with self-adhesive rubber membrane up to 4 ft. within the roof edge

If you see evidence of leaks close to exterior walls, gently lift the edges of a couple shingles (when they are warm) at the eaves to see if there's a thick black rubber membrane beneath it. If the membrane is missing that could be contributing to the problem.

Leaks can also occur in a roof for reasons other than flashing failure. Some reasons are easy to spot, others not so much. The easy ones include:

Missing, torn and storm-damaged shingles;
Curled, cracked and dried-out shingles.
If there are only a few problem areas, leaking may be stopped with spot patches or limited shingle replacement.

Other problems may be due to poor overall workmanship including:

Improper lapping of underlayment;
Popped nails or otherwise inadequate nailing; look for dimples in the shingle surface;
Failure to stagger shingle end butts adequately; vertical joints should be offset by at least six courses (a course is a horizontal row of shingles);
Improper selection of material and lap patterns on low-slope roofs; asphalt shingles are not recommended for roof with less than 3:12 pitch.
Discovering any of these defects unfortunately means that you're likely going to need to tear off the roofing and put on new underlayment and shingles.

But before you let a contractor talk you into a whole new roof, ask him to show you where the leaks are coming from. If you don't want to go up on the roof yourself, get him to take you on a tour of the defects via smartphone video. Remember, most leaks can be stopped with properly applied spot patches.
