Trusted roof waterproofing in Winona, MN. Our certified crews deliver precision workmanship and guaranteed results.
For Winona 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 Winona, MN 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 Winona crews have seen every roof waterproofing scenario Minnesota 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 Winona 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.
"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."
"Lapolla Industries coated our standing seam metal roof with a reflective system that stopped the leaks at the panel overlaps. The building stays significantly cooler in summer and the coating has held up perfectly through two winters."
"We manage a 40,000 square foot retail center and the roof was near end of life. Instead of tearing it off they restored it with a spray foam and coating system. Saved us over sixty percent versus replacement and added twenty years of life."
