Spray Foam Masters –
Commercial and Residential Roofing and Insulation
Foam Roofing provides GREEN SOLUTIONS for building sustainability and energy use reduction. Spray Polyurethane Foam Roofing has the highest rated insulation “R” value available.
Wind-uplift tests performed by UL™ (Underwriters Laboratories) have shown that polyurethane foam actually enhances the wind-uplift resistance of the substrate.
Foam Roofing helps you to achieve maximum ROI by monolithically integrating directly with solar photovoltaic. Find out how you can use the Leadership in Energy and Environmental Design (LEED) Green Building Rating System™ to benchmark performance.
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 web site you will learn a lot more about them. Here are some brief examples:
Spray Foam Roofs are Seamless – Spray foam roofs form a seamless roofing system. To be seamless means it has no joints or seams that often allow outside water and air to pass through the roofing system into the building structure.
Spray on Roofs Eliminate Flashing leaks – Because a spray foam roof conforms to the substrate when installed, this seamless system is ideal for flashing parapet walls, equipment, skylights, and cooling towers. Many roof leaks are caused by faulty flashing, and spray foam roofs solves this problem.
Spray Foam Roofs can Eliminate Troublesome Ponding Water – In re-roofing applications, ponding water may be eliminated by adding an increased thickness of roof insulation, called spray foam, in low areas. Building up the low areas and sloping the roof so that it drains properly will eliminate ponding water. It will also help reduce additional weight load caused by this water accumulation.
Spray on Roofs are Lightweight and are Excellent Roof Insulation – The weight of roof insulation is around 3 pounds per cubic foot. One inch of polyurethane foam roofing weighs approximately 60 pounds per 100 square feet. This is considerably less when compared to approximately 600 pounds per 100 square feet for a conventional, four-ply, built-up roofing system. This makes a spray foam roof system ideal for re-roofing, as it is possible to apply over an existing built-up roof without removing it.
Spray Foam Roofs have the Highest “R” Value – Spray foam roofs has an aged “R” value of 6.2 – 6.5, enabling it to provide more thermal resistance with less material than any other roof insulation. In most cases, a spray foam roof will pay for itself in 5-8 years in energy savings.
Foam Roof Insulation is Chemically Stable – Spray foam for roof insulation is inert, but this type of roof insulation has to be protected from sunlight by a U.V. resistant elastomeric roof coating system. A spray foam roof is odorless, resists attack by either mildew or fungi and has no nutritional value. There are no bad odors for you or your neighbors while spray foam roofing is being applied.
Foam Roofs Minimizes Thermal Shock – Due to characteristic such as being seamless, having a high “R” value, and being protected by a white elastomeric coating, spray foam roofing is able to greatly reduce the effects of thermal shock on a structure.
Spray on Roofs have Great Versatility – Spray foam roofs can be used on both new construction, as well as to replace old roofs. Spray foam can be applied to flat, pitched, saw-toothed, and domed or having unusual slopes or configurations. Spray foam is also an ideal spray application for tanks, freezers, coolers, piping, ductwork and various other odd jobs.
Spray Foam Roofs are Rigid – While spray foam roofs are very lightweight, these spray on roofs are also strong and will not pack down or sag.
Foam Roofs are Flexible – Spray on roofs have the ability to withstand normal expansion and contraction without affecting the ability to keep the structure protected from the outside elements.
Spray on Roofs are Watertight – Spray foam roofs are composed of billions of minute closed cells which resist the penetration of water and vapors. It must, however, be protected by an elastomeric roof coating or crushed rock for use in an outdoor environment.
Spray Foam Roofs are Long Lasting – The elastomeric roof coating system, which protects the spray roof insulation, can be rejuvenated by the re-application of additional roof coatings. This doesn’t take place until the initial coatings system has weathered after many years of service. The normal wear of a quality coating has a life span of about 15-20 years.
Foam Roofs have Little Disruption to Building Owner – A spray foam roof system can be applied in a relatively short period of time with little or no disruption of building operations. This is due to little or no tear off of the existing roof, and little manpower needed to apply the spray foam roof.
Spray on Roofs are Easy to Maintain – Minor repairs or modifications to a spray foam roof system can be made by in-house maintenance personnel at minimal cost.
