A sprayed polyurethane roof 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. Regardless the size of your roof, it will have no seams.
Urethane foam roofing is a sprayed-on system of insulation and coating that benefits the owner with versatility and flexibility in design. Contact the experienced team at Washington Roofing & Insulation, Inc. today for more information.
In reroofing applications, ponding water may be eliminated by adding an increased thickness of polyurethane insulation in low areas. Building up the low areas and sloping the roof, so that it drains properly and eliminates the ponding water and additional load factor that is caused by water accumulation.

The weight of polyurethane insulation is between 2 - 3 pounds per cubic foot. One inch of polyurethane insulation plus 30 mils of an elastomeric coating weighs 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 roof system ideal for reroofing, as it is often possible to apply over an existing built-up roof without removing it.
Sprayed polyurethane insulation has an "R" value of 6.7 per inch, enabling it to provide more thermal resistance with less material than any other insulation.
Polyurethane roof systems are chemically inert. They are odorless, resist attack by either mildew or fungi, and have no nutritive value.
While sprayed polyurethane insulation is very lightweight. It is strong and will not pack down or sag.
Because a polyurethane roof system is seamless, it has a high "R" value and uses a reflective elastomeric coating. It greatly reduces the thermal shock, that a building is subjected to, by fluctuating outdoor temperatures.
Polyurethane insulation 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 application to tanks, freezers, coolers, piping, ductwork, and various aerospace projects.
It has the ability to withstand a structure's normal expansion and contraction without affecting the ability to keep the structure protected from the outside elements.
Polyurethane insulation is made of billions of minute, closed cells which resist the penetration of water and vapors. It must, however, be protected by an elastomeric coating suited for use in that particular environment. Elastomeric coatings are specifically engineered for this purpose.
The elastomeric coating system, which protects the polyurethane insulation, can be rejuvenated by the reapplication of an additional coating after the initial coating system has weathered after many years of service.
A polyurethane roof system can be applied in a relatively short period of time with little or no disruption of building operations by our experienced and qualified roofing crew.
Minor repairs or modifications to a polyurethane roof system can be made by our in-house maintenance personnel. All that is needed is a hand caulking gun and a tube of caulk.

Because a sprayed polyurethane roof system 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 solves this problem.
