With over two decades of spray foam experience, our Simi Valley crews have seen every roof replacement scenario California weather can create. We use that experience to select the right foam type, coating system, and application method for your specific property — delivering roof replacement results that hold up to Simi Valley conditions year after year.
From inspection to completion, here is how we deliver professional roof replacement results.
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.

Our reputation is built on results. Here is what our customers have to say.
"Had our attic insulated with spray foam after years of fiberglass that kept settling and losing its R-value. Lapolla Industries did a clean install — no gaps, no missed spots. Our HVAC system runs half as much now."
"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."
"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."
