Flat Roof Repair Services in Merrimack

Merrimack property owners with leaking flat roofs have tried everything — tar, caulk, peel-and-stick patches. None of it lasts because none of it addresses why the roof leaks. Lapolla Industries finds the actual failure point and repairs it with materials engineered for flat roof performance in New Hampshire weather conditions.

When Merrimack, NH property owners need flat roof repair, 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 Merrimack crews have seen every flat roof repair 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 flat roof repair results that hold up to Merrimack conditions year after year.

Our Flat Roof Repair Process

How our certified crews deliver precision flat roof repair in Merrimack, NH.

1

Inspection & Assessment

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.

2

Surface Preparation

Proper surface preparation is critical for spray foam adhesion and long-term performance. Our crews clean, dry, and prime all surfaces, remove debris and loose material, and ensure the substrate meets manufacturer specifications before any foam is applied.

3

SPF Application

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.

4

Protective Coating & Cleanup

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.

What Our Customers Say

Real feedback from property owners who trusted Lapolla Industries with their spray foam projects.

★★★★★

"Our old three-layer built-up roof was beyond saving. They stripped everything down to the deck, repaired the substrate, and installed a new spray foam roofing system. The building is better insulated now than it has ever been."

— Sandra Lattimore
★★★★☆

"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."

— Dennis Enriquez
★★★★★

"Our crawl space was damp, musty, and completely uninsulated. They sealed all the rim joists and band boards with closed-cell foam. The floors above are warmer and the moisture problem is gone. Should have done this years ago."

— Dorothy Underwood
