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 waterproofing 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.
Our preparation process includes substrate inspection, cleaning, moisture testing, and priming. We mask all areas not receiving foam, set up containment where needed, and verify that temperature and humidity conditions are within specification for application.
Our factory-trained crews apply spray polyurethane foam using calibrated equipment that ensures consistent thickness, proper density, and complete coverage. The foam expands on contact, fills every gap, and bonds permanently to the prepared substrate.
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 foam roof had some blistering and a couple of punctures from a maintenance crew walking on it. They repaired everything in one visit — cut out the damaged foam, re-sprayed, and recoated. Good as new."
"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."
"We signed up for their annual roof maintenance program for our three commercial buildings. They catch small issues before they become expensive repairs. Last inspection they found a failing pipe boot that would have caused a major leak."
