Trusted roof waterproofing in Decatur, IN. Our certified crews deliver precision workmanship and guaranteed results.
For Decatur 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.
The buildings and homes of Decatur, IN face unique challenges — from seasonal temperature extremes to storm exposure — that demand roofing and insulation systems built for performance, not just price. Lapolla Industries delivers roof waterproofing solutions using closed-cell spray polyurethane foam that outperforms conventional materials in every measurable category.
Our Decatur customers see the difference in their energy bills, their comfort levels, and the longevity of their roofing systems. Spray foam does not degrade like fiberglass, does not develop seam failures like TPO, and does not crack like built-up roofing. It is a permanent solution — and Lapolla Industries is the permanent partner Decatur property owners rely on to deliver it right.
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.
"Got a comprehensive inspection done on our warehouse roof. They found three areas of trapped moisture that were invisible from the surface. The early detection saved us from much more expensive structural repairs down the road."
"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."
"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."
