Our Roof Waterproofing Process

A systematic approach to roof waterproofing that ensures lasting performance.

1

Inspection & Assessment

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.

2

Surface Preparation

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.

3

SPF 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.

4

Protective Coating & Cleanup

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.

What Our Customers Say

Honest reviews from property owners who chose Lapolla Industries for their roofing and insulation needs.

★★★★★

"Had spray foam applied to our crawl space walls and rim joists. The difference in floor temperature upstairs is dramatic. Our furnace cycles less and the energy savings paid for the project faster than they estimated."

— Betty Jacobson
★★★★★

"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."

— Michelle Preston
★★★★★

"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."

— Linda Sandoval
