Spray Foam Roofing is Sustainable
Architects, builders, and owners have created an awareness in sustainable building. This awareness has generated increased interest in the roofing industry to reveal a sustainable roofing system for commercial, industrial and residential applications.
A system that doesn't leak, supports energy conservation, and warrants the confidence of the building owner, engineer and architect.
Foam Roofs have no seams to split or pull apart and allow water to enter. Foam is ideal for saw tooth or other irregular roof shapes that are difficult or impractical for old fashioned low-tech roofing materials.
Sprayed Polyurethane Foam is also the best insulator on the market. Very little maintenance or repair is ever needed, and with proper care, it is the last roof you will ever need to buy.
Foam Roof Density and R-Value
Density of SPF is important when it comes to strength and Thermal Resistance. Obviously, higher density means increased strength and higher R-value. Most SPF roofs have densities ranging from about 2.5 pounds per cubic foot to 3 pounds per cubic foot.
High-density SPF roofing foam is a rigid, closed-cell plastic created by a combination of two liquid components, which react in seconds and can be walked on in a matter of minutes. These roofs provide high compressive strengths that increase durability, endure foot traffic, and resist impact and storm damage.
Life Cycle Cost
With the rising cost of building materials and the eradication of environmental resources it is not feasible or profitable to incur expensive annual life cycle costs or to replace a roof every 10 to 15 years.
The life cycle cost of a roof is defined as the present value of all the costs associated with the roof from initial installation until reroof. Sustainable roof systems are becoming increasingly important. Sustainable systems installed by Brite Foam Foam Roofing preserve natural resources, reduce landfill waste and provide maximum life cycle cost efficiency.
Spray Foam self flashes to all protrusions (vents, pipes, etc...) There is no flashing tape or adhesive to peel away. The flashing becomes part of a seamless covering.
What is SPF? (Sprayed Polyurethane Foam)
Sprayed Polyurethane Foam is a combination of isocyanate and polyol. These two components are fed through a proportioner which heats then pumps the two separate components to the spray gun, where they are mixed and sprayed onto the substrate.

Because it is sprayed onto the roof as a liquid, it forms a single continuous structure that is seamless and very stable. SPF requires a clean surface for proper application. It must be dry, free of contaminants like oil, and properly fastened to the substrate in accordance with the proper building codes.
A protective elastomeric top coat is required which is typically sprayed on as well, but it is also possible to be applied with hand or power rollers.
Foam roofing has many advantages over traditional roofing methods, and as you read through this website you will learn a lot more about them. Here are some brief examples:
Three pound density foam has a compressive strength of about 50 psi and an R-value of 7.14 installed and 6.86 aged (these numbers may vary slightly depending on the foam manufacturer.

Here's an example of how well a good SPF roof insulates. A school district in southern Texas had recently installed some new, one-room relocatable classroom buildings.
During the late spring and early fall, these classrooms were using their air conditioners an average of 50 minutes every hour. The school district installed foam roofs on some of these classrooms in order to see if it would provide an energy savings.
The roofs consisted of three pound density foam, 1.5 inches thick with an acrylic coating system. The air conditioner usage was cut down to fifteen minutes every hour. That's a fifty-eight percent savings on energy costs.
Polyurethane foam and our elastomeric coatings will SEAL and totally ENCAPSULATE your flat roof protecting it from the weather.
Localized repairs are made if required to the roof. It is swept free of debris and sprayed with a layer of foam. Then our acrylic elastomeric coating is sprayed on top to protect the foam.
The result is a totally encapsulated, weather proofed and seamless roof, protected for years to come. You will of course benefit from exceptional insulation as well.
Protrusions are a prime source of trouble.
SPF's Waterproofing Ability
Sprayed Polyurethane Foam is perfect for many different waterproofing applications. Because it is composed of billions of closed cells, the foam acts as an air barrier, preventing moisture infiltration into the building.

This ability minimizes dew point problems, which unchecked lead to water condensation inside of the structure. Moisture infiltration into the building envelope is the number one cause of building deterioration.
Even when the top coat of a foam roofing system is damaged, the underlying foam will keep the roof from leaking. The Superdome in New Orleans was damaged once in a severe hail storm. Thousands of hairline cracks appeared in the top coat, but no leaks ever occurred, even though it wasn't repaired for over a decade!
If a penetration does occur all the way from the foam layers, the water infiltration will be isolated only to the area where the membrane has been penetrated. Small penetrations in foam roofing systems can be repaired easily with an elastomeric caulk, reinstating the integrity of the system.
Water ponding is quite often a problem with conventional roofing systems. When applying the polyurethane foam in reroofing situations, it is very easy to build up areas of greater thickness while spraying so that water will drain properly. This also eliminates the problem of the additional weight load associated with water accumulation
A foam roof system can also save you monthly on your monthly utility bills. You will realize the savings almost immediately after we have installed the foam roof system for you.
The Physical Plant Department at Texas A&M University (TAMU) Systems Facilities Planning and Construction department started monitoring their newly applied foam roof systems from 1980 to 1984.
