Polyurethane Foam

This polyurethane foam roof was installed over ten years ago. On average, most of these type roofs have 1 to 2 inches of foam sprayed onto an existing roof substrate such as a built up, modified bitumen, or metal roof. They are then coated with either an acrylic or silicone roof coating. Polyurethane foam is a great roof system, but must be coated every ten years to protect it from the sun's harmful UV rays.

Installing the Diversified Coatings system requires cleaning the top surface of the roof with 1,500 to 2,000 psi of pressure. We do not recommend heavy power-washing in order to not damage the current coating system installed on the roof. We do recommend a detergent, such as TSP, to clean any heavy residue off the roof surface.

The next step is to cut out any damaged foam and spray additional foam in the damaged areas to match the current foam system. It is especially important to cut out any areas where water has saturated the system. If there are only small blisters, these may be cut out and patched using a polyester fabric and one of our top coats to seal the area.

After all areas of concern are addressed, we applied a fabric bond material to the entire roof area to ensure that our top coating will adhere to the current system. Finally, two coats of our durable top coat are sprayed on the roof surface to form a seamless, bright white membrane to protect the foam from UV rays for many years to come.
