Spray polyurethane foam (SPF) is sprayed directly onto the existing roof deck, expanding into a seamless, fully-adhered membrane that insulates and waterproofs in one step. Because it’s seamless, there are no laps or seams for water to find.
Strong Contractors is an SPFA-accredited installer, applying SPF systems finished with a protective siliconee or acrylic coating to guard against UV degradation and foot traffic.
