SPF & Spray Polyurethane Foam Roof Repair in Indianapolis

Spray polyurethane foam (SPF) roofing is a seamless, fully-adhered system applied as a liquid and expanded to form a rigid foam substrate, then protected by an elastomeric topcoat — typically silicone, acrylic, or urethane. SPF is valued for its high R-value per inch, seamless coverage, and ability to fill irregular substrates and penetrations without seams.

The topcoat is the waterproofing layer on an SPF system. When the topcoat weathers past the minimum film thickness (typically 10–20 mils), re-coating is the standard repair rather than full replacement of the foam substrate. Most SPF roofs are designed to be re-coated on a 10–20 year cycle, extending the original foam substrate’s service life indefinitely when maintained.

Common SPF repair scopes include cracking and crazing of the topcoat from UV degradation, bird-pecking damage to the foam substrate, impact and foot-traffic damage, flashing failure at penetrations and parapets, and water intrusion where damage has penetrated through the topcoat into the foam. When foam is water-damaged, the affected section is cut out, dried, and replaced before the area is re-coated.
