About Us

Spray Foam Roofing

We are waterproofing and Insulation contractors and consulting professionals specializing in Spray Polyurethane Foam roofing and Polyurea Systems technology and applications.


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

Eliminates Flashing Leaks

Because Alien Foam Roofing 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. Alien Foam Roofing solves the problem.

Elimination of Pond Water

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.


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 Alien Foam Roofing system ideal for reroofing as it is often possible to apply over an existing built-up roof without removing it.

Highest “R” Value

Alien Foam Roofing has an R-value of 6.50 to 7.14 per 1 inch thickness, enabling it to provide more thermal resistance with less material than any other insulation.

Chemically Stable

Alien Foam Roofing, 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

Because Alien 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.


Alien Foam Roofing 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.


While Alien Foam Roofing is very light weight, it is strong and will not pack down or sag.


Alien Foam Roofing has the ability to withstand a structures normal expansion and contraction without affecting the ability to keep the structure protected from the outside elements.


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 environment.


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

Ease of Application

A sprayed 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

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.
