Spray Foam (SPF) Roof Recoating in Phoenix, Arizona
Polyurethane spray foam roofs are extremely common on Phoenix mid-century homes and commercial buildings due to their superior thermal insulation. However, foam requires a seamless protective elastomeric silicone coating to block UV degradation.
Every 5 to 10 years, the topcoat must be renewed. Dispatched specialists power-wash the surface, patch bird pecks with elastomeric caulk, clear scuppers, and apply high-solids silicone coating to restore complete monolithic waterproofing.
