A systematic approach to attic insulation that ensures lasting performance.
Our assessment process goes beyond a visual check. We examine substrate conditions, drainage patterns, existing insulation performance, and structural integrity. This data-driven approach ensures we recommend the right spray foam solution for your specific property.
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.
Application is performed by certified spray foam technicians using the latest proportioning equipment. We monitor foam temperature, pressure, and ratio throughout application to ensure every square foot meets manufacturer performance specifications.
The final step is applying a protective topcoat that shields the SPF from UV exposure and provides the weather surface. We select the coating type based on your roof slope, ponding conditions, and desired service life. After coating, we clean up completely and review the finished project with you.

Honest reviews from property owners who chose Lapolla Industries for their roofing and insulation needs.
"Ponding water on our flat roof was causing constant problems. They re-sloped the low spots with tapered foam and applied a silicone coating. No more standing water after rain. Excellent work."
"Our 18-year-old roof was showing its age but still structurally sound. Lapolla Industries recommended restoration over replacement and it was the right call. New coating, sealed seams, and a 15-year warranty. Smart investment."
"Lapolla Industries restored the roof on our distribution warehouse without any disruption to our operations. The crew worked in sections and we never had to shut down. The new reflective coating has already reduced our cooling load."
