We handle every step — from surface preparation and substrate evaluation to final coating and cleanup — so you get a turnkey result with zero hassle and complete confidence in the finished product.
A systematic approach to roof inspection that ensures lasting performance.
Before any work begins, our certified inspectors evaluate your property and provide a comprehensive assessment including current condition, repair needs, and recommended SPF solutions. You get a written estimate with no hidden fees.
Proper surface preparation is critical for spray foam adhesion and long-term performance. Our crews clean, dry, and prime all surfaces, remove debris and loose material, and ensure the substrate meets manufacturer specifications before any foam is applied.
Using precision spray equipment, our crews apply the foam in controlled passes to achieve the specified thickness and density. The closed-cell foam expands 30 to 40 times its liquid volume, conforming to every detail of the surface and creating a seamless monolithic barrier.
We finish every project with the appropriate protective coating, thorough cleanup, and a detailed walkthrough. You receive project documentation including photos, material specifications, warranty registration, and maintenance recommendations.

"Full roof replacement on our 12,000 square foot commercial building. Lapolla Industries removed the old single-ply membrane and installed spray foam with a silicone topcoat. Clean work, professional crew, and a 20-year warranty."
"Our corrugated metal roof was rusting at every fastener and seam. They cleaned the entire surface, treated the rust, and applied a thick elastomeric coating. The roof looks brand new and is completely sealed now."
"Our old three-layer built-up roof was beyond saving. They stripped everything down to the deck, repaired the substrate, and installed a new spray foam roofing system. The building is better insulated now than it has ever been."
