A systematic approach to attic insulation that ensures lasting performance.
Every project begins with a thorough inspection of your property. We evaluate the existing condition, identify problem areas, and use infrared moisture scanning when needed to reveal hidden issues. You receive a detailed report with photos and honest recommendations.
We prepare every surface according to factory guidelines — cleaning contaminants, addressing moisture, repairing damaged substrate, and verifying adhesion conditions. This step is not glamorous, but it is the foundation of a spray foam system that lasts decades.
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.
After the foam cures, we apply a UV-protective coating — silicone, acrylic, or elastomeric — selected for your specific application and climate. We then remove all masking, clean up the work area, and conduct a final walkthrough with you to verify satisfaction.

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."
"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."
"Our old three-layer built-up roof was beyond saving. They stripped everything down to the deck, repaired the substrate, and installed a new spray foam roofing system. The building is better insulated now than it has ever been."
