What Is Spray On Roofing?

Spray on roofing is a liquid-applied system that solidifies into a durable, waterproof membrane. It's typically made from polyurethane foam, acrylic, or silicone. This method is famous for its ability to create a seamless, insulating, and protective layer over a roof, which is particularly effective for flat or irregularly shaped roofs.

Will Water Leak Through Spray Foam?

Properly applied spray foam should not allow water to leak through. It creates a watertight seal that covers cracks and seams, effectively preventing leaks. However, if the foam is incorrectly applied or deteriorates over time without proper maintenance, it could allow water penetration. Regular inspections and timely repairs are crucial to maintaining its waterproof integrity.
