Trusted roof restoration in Londonderry, NH. Our certified crews deliver precision workmanship and guaranteed results.
Roof restoration in Londonderry, NH makes sense when your roof structure is sound but the surface is deteriorating. Lapolla Industries cleans, repairs, and recoats your entire roof with a spray foam and silicone system that adds 20 or more years of warranted life — at 50 to 70 percent less than full replacement.
When Londonderry, NH property owners need roof restoration, 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 Londonderry crews have seen every roof restoration scenario New Hampshire weather can create. We use that experience to select the right foam type, coating system, and application method for your specific property — delivering roof restoration results that hold up to Londonderry conditions year after year.
From inspection to completion, here is how we deliver professional roof restoration results.
Our assessment process goes beyond a visual check. We examine substrate conditions, drainage patterns, existing insulation performance, and structural integrity. This data-driven approach ensures we recommend the right spray foam solution for your specific property.
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.
Our factory-trained crews apply spray polyurethane foam using calibrated equipment that ensures consistent thickness, proper density, and complete coverage. The foam expands on contact, fills every gap, and bonds permanently to the prepared substrate.
The final step is applying a protective topcoat that shields the SPF from UV exposure and provides the weather surface. We select the coating type based on your roof slope, ponding conditions, and desired service life. After coating, we clean up completely and review the finished project with you.

"Our 18-year-old roof was showing its age but still structurally sound. Lapolla Industries recommended restoration over replacement and it was the right call. New coating, sealed seams, and a 15-year warranty. Smart investment."
