Need roof waterproofing in Cottage Grove? Lapolla Industries provides free inspections, transparent pricing, and warranted spray foam solutions across MN.
For Cottage Grove 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.
In Cottage Grove, MN, the difference between a spray foam job that lasts and one that fails comes down to the contractor. Lapolla Industries applies the same quality standards to every roof waterproofing project that earned us a reputation as one of the nation's most trusted SPF specialists — proper surface prep, correct foam thickness, and factory-specified coating application.
Every roof waterproofing project we complete in Cottage Grove is backed by both manufacturer material warranties and our own workmanship guarantee. We document every step with photos and measurements, provide you with a detailed project report, and remain available for warranty service and maintenance throughout the life of your SPF system.
Our proven process ensures quality results on every spray foam project.
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.

"Had spray foam applied to our flat commercial roof and the difference is night and day. No more ponding water, energy bills dropped noticeably, and the seamless membrane means zero leak points. Should have done this years ago."
"We had a persistent leak that three different contractors could not find. Their team used moisture scanning equipment and pinpointed it to a failed pipe boot in minutes. Fixed it the same day. Incredible diagnostic work."
"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."
