Trusted roof waterproofing in Commerce, CA. Our certified crews deliver precision workmanship and guaranteed results.
For Commerce property owners dealing with chronic roof moisture problems, our waterproofing approach starts with diagnosis — we identify where water enters and why it ponds — then we apply a seamless SPF membrane that solves both problems permanently.
When Commerce, CA property owners need roof waterproofing, they turn to Lapolla Industries for the same reason thousands of customers nationwide do: we solve the root problem, not just the symptom. Our diagnostic approach uses infrared scanning, moisture mapping, and visual inspection to ensure the solution we recommend is the one your building actually needs.
With over two decades of spray foam experience, our Commerce crews have seen every roof waterproofing scenario California weather can create. We use that experience to select the right foam type, coating system, and application method for your specific property — delivering roof waterproofing results that hold up to Commerce conditions year after year.
From inspection to completion, here is how we deliver professional roof waterproofing results.
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.

Real feedback from property owners who trusted Lapolla Industries with their spray foam projects.
"Lapolla Industries restored the roof on our distribution warehouse without any disruption to our operations. The crew worked in sections and we never had to shut down. The new reflective coating has already reduced our cooling load."
"Attic insulation upgrade from blown-in to spray foam. The crew masked everything off properly and the overspray was minimal. The temperature in our attic dropped dramatically and so did our energy bills. Worth the investment."
"Instead of a full tear-off our old commercial roof got a complete restoration — cleaned, repaired, and recoated with a reflective silicone system. Saved us tens of thousands compared to replacement and it looks brand new."
