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.

★★★★★

"We needed our concrete roof deck waterproofed before installing new equipment on it. The crew applied a monolithic membrane that handles foot traffic and ponding water. Two years in and zero issues. Money well spent."

— Steven McAllister
★★★★☆

"Regular maintenance visits twice a year keep our flat roof in great shape. They clean drains, check seams, inspect all penetrations, and send a detailed report with photos. Good preventive program at a reasonable cost."

— Kenneth Ostrowski
★★★★★

"They sprayed closed-cell foam in our attic and the difference was immediate. Our upstairs bedrooms are finally comfortable year-round and our heating bill dropped by about thirty percent. The crew was in and out in one day."
