Trusted roof leak repair in Cornwall, NY. Our certified crews deliver precision workmanship and guaranteed results.
Three contractors tried to fix this leak and failed — that is what we hear from Cornwall property owners every week.

When Cornwall, NY property owners need roof leak repair, 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 Cornwall crews have seen every roof leak repair scenario New York weather can create. We use that experience to select the right foam type, coating system, and application method for your specific property — delivering roof leak repair results that hold up to Cornwall conditions year after year.
From inspection to completion, here is how we deliver professional roof leak repair 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.
"Our foam roof had some blistering and a couple of punctures from a maintenance crew walking on it. They repaired everything in one visit — cut out the damaged foam, re-sprayed, and recoated. Good as new."
"Our corrugated metal roof was rusting at every fastener and seam. They cleaned the entire surface, treated the rust, and applied a thick elastomeric coating. The roof looks brand new and is completely sealed now."
"We converted our old built-up roof to spray foam and could not be happier. The insulation value alone has cut our HVAC costs significantly. The crew explained every step and left the site spotless."
