Sprayed Polyurethane Foam Roofing
Sprayed Polyurethane Foam (SPF) roofing systems with Dow® coatings are a popular choice among owners of both new and existing flat-roofed buildings. The system provides a durable, waterproof covering that bond tightly to nearly any properly prepared surface. It's so lightweight that it can be applied over most existing roof systems without exceeding the structural load capacity, yet it is amazingly strong. Foam roofing systems are seamless and use no mechanical fasteners, virtually eliminating leaking problems. To further discourage leaks, a subtle slope can be easily built into your foam system to prevent pounding. In addition, SPF's closed-cell structure prevents horizontal movement with water so should you get a leak, it is contained to one area, making it easy to find and repair.
