Expert flat roof repair in Grafton, WI. Licensed spray foam contractors with manufacturer-backed warranties and free inspections.
Grafton 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 Wisconsin weather conditions.
When Grafton, WI 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 Grafton crews have seen every flat roof repair scenario Wisconsin 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 Grafton conditions year after year.
From inspection to completion, here is how we deliver professional flat roof repair 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.
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.
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.
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.
