What are some Advantages of Foam Roofing?

The SPF System as it is commonly referred to is a closed cell roofing and insulating membrane that is sprayed-in-place on site. The foam membrane is then coated with an elastomeric coating to help protect the foam from the elements such as ultraviolet degradation

Example of Foam Roofing Application: Energy Savings
Since 1975, Texas A&M University has exclusively used SPF roof systems to protect campus buildings from the elements. In addition to leak free protection the University has realized tremendous cost reduction through energy savings. The results of an in-house survey are listed below indicating a four and a half year payback, strictly through reduced utility bills.

Results of the study performed by Gerald Scott, Director of Energy, A&M University.

Mitigate Loss Caused by Storm Damage
SPRAY POLYURETHANE FOAM ROOFING, with its high wind-uplift capabilities, seamless surface, high insulation R-value, and quick installation by skilled professionals is the answer...

Hurricane Charley
		Two buildings in the path of hurricane Charley, one with spray foam roofing over metal, one without. This photo show that the standard R-panel metal roof on "The Drage Corp" building was pealed off, exposing it's interior to the powerful cat 4 hurricane.

Mason Knowles, technical director of the Spray Polyurethane Foam Alliance, reports that during laboratory testing of SPF systems, SPF’s wind uplift resistance exceeded the capacity of UL’s equipment. UL also observed that SPF roofs applied over BUR and metal increased the wind uplift resistance of those roof coverings. He says FM Global’s testing showed similar results over concrete, metal, and wood.

SEAMLESS top of page
Spray polyurethane foam forms a seamless insulated roofing system. It has no joints or seams that often allow outside water and air to pass through the roofing system into the building structure. Whether a roof is 10,00 square feet, 100,000 square feet or larger in size, it will have no seams.

ELIMINATES FLASHING LEAKS top of page
Because spray polyurethane foam conforms to the substrate and when installed, is a seamless system, it is ideal for flashing parapet walls, roof penetrations and roof mounted equipment, including vents, pipes, stacks, HVAC equipment, skylights, and cooling towers. Many roof leaks are caused by faulty flashings. Sprayed polyurethane foam solves the problem.

ELIMINATION OF PONDING WATER top of page
In reroofing applications, ponding of water may be eliminated by adding an increased thickness of polyurethane foam in low areas. Building up the low areas and sloping the roof so that it drains properly will eliminate ponding water and the additional load factor that is caused by water accumulation.

LIGHTWEIGHT top of page
The weight of polyurethane foam is between 2-3 pounds per cubic foot. One inch of polyurethane foam insulation plus 30 mils of an elastomeric coating weight approximately 60 pounds per 100 square feet, as compared to approximately 600 pounds per 100 square feet for a typical conventional four-ply built-up roofing system. This makes a sprayed polyurethane foam system ideal for reroofing as it is often possible to apply over an existing built-up roof without removing it.

HIGHEST "R" VALUE top of page
Spray polyurethane foam has an R-value of 6.5 per 1 inch thickness, enabling it to provide more thermal resistance with less material than any other insulation.

CHEMICALLY STABLE top of page
Spray polyurethane foam, although inert, must be protected from sunlight by a UV resistant elastomeric coating. It is odorless, resists attack by either mildew or fungi and has no nutritive value.

MINIMIZES THERMAL SHOCK top of page
Because a polyurethane foam roofing system is seamless, has a high "R" value and is covered by a reflective elastomeric coating, it greatly reduces the thermal shock a building is subjected to because of fluctuating outdoor temperatures.

VERSATILITY top of page
It can be used on both new and replacement roofs, whether flat, pitched, saw-toothed, domed or having unusual slopes or configurations. It is also ideal for the spray application to tanks, freezers, coolers, piping, ductwork and various aerospace projects.

RIGIDITY top of page
While spray polyurethane foam is very light weight, it is strong and will not pack down or sag.

FLEXIBILITY top of page
It has the ability to withstand a structures normal expansion and contraction without affecting the ability to keep the structure protected from the outside elements.

WATERTIGHT top of page
Polyurethane foam is made of billions of minute closed cells which resists the penetration of water and vapors. It must, however, be protected by an elastomeric coating suited for use in that particular environment.

LONG LASTING top of page
The elastomeric coating system which protects the polyurethane foam can be rejuvenated by the re-application of additional coatings after the initial coatings system has weathered after many years of service.

EASE OF APPLICATION top of page
A spray polyurethane system can be applied in a relatively short period of time with little or no disruption of building operations by an experienced qualified polyurethane foam contractor.

EASE OF MAINTENANCE top of page
Minor repairs or modifications to a polyurethane system can be made by in-house maintenance personnel at minimal cost. All that is needed is a hand caulking gun and a tube of caulking.

MATERIAL SELECTION
Due to the lack of proper public education, there are many misgivings about polyurethane foam. Most people still refer to it as "Styrofoam stuff" or worse yet, they believe it to be hazardous material. However, there ARE many different types of formulations in this field, and custom designing the proper system for geographical location is VERY important.

SKILLED CRAFTSMEN
This is the most crucial element for installation of ANY SYSTEM currently on the market today. Check references..ask to see an existing jobsite...ask to talk directly with one or more of their customers who currently use the same system.
