A systematic approach to roof waterproofing that ensures lasting performance.
Before any work begins, our certified inspectors evaluate your property and provide a comprehensive assessment including current condition, repair needs, and recommended SPF solutions. You get a written estimate with no hidden fees.
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.
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.
We finish every project with the appropriate protective coating, thorough cleanup, and a detailed walkthrough. You receive project documentation including photos, material specifications, warranty registration, and maintenance recommendations.

Honest reviews from property owners who chose Lapolla Industries for their roofing and insulation needs.
"Had our entire warehouse roof restored with a spray-applied coating system. The crew worked around our operations without any disruption. The finished roof reflects heat beautifully and our AC runs less. Win-win."
