Trusted flat roof repair in Lebanon, NH. Our certified crews deliver precision workmanship and guaranteed results.
If your flat roof in Lebanon has been repaired multiple times and still leaks, the problem is likely systemic — failed seam adhesive, deteriorated flashing, or inadequate drainage slope. Our NH crews identify these underlying issues and resolve them permanently using spray foam and liquid-applied membrane systems.
The buildings and homes of Lebanon, NH 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 flat roof repair solutions using closed-cell spray polyurethane foam that outperforms conventional materials in every measurable category.
Our Lebanon 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 Lebanon property owners rely on to deliver it right.
From inspection to completion, here is how we deliver professional flat roof 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.
Our preparation process includes substrate inspection, cleaning, moisture testing, and priming. We mask all areas not receiving foam, set up containment where needed, and verify that temperature and humidity conditions are within specification for application.
Using precision spray equipment, our crews apply the foam in controlled passes to achieve the specified thickness and density. The closed-cell foam expands 30 to 40 times its liquid volume, conforming to every detail of the surface and creating a seamless monolithic barrier.
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.
"They waterproofed our entire flat roof with a seamless elastomeric membrane. Two years later and not a single drop of water has gotten through. The application was clean and fast — three days for 8,000 square feet."
"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."
"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."
