When Duluth, MN property owners need roof leak repair, they turn to Lapolla Industries for the same reason thousands of customers nationwide do: we solve the root problem, not just the symptom.

With over two decades of spray foam experience, our Duluth crews have seen every roof leak repair scenario Minnesota weather can create. We use that experience to select the right foam type, coating system, and application method for your specific property — delivering roof leak repair results that hold up to Duluth conditions year after year.
From inspection to completion, here is how we deliver professional roof leak 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.
