When DeKalb, IL property owners need roof replacement, 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 DeKalb crews have seen every roof replacement scenario Illinois weather can create. We use that experience to select the right foam type, coating system, and application method for your specific property — delivering roof replacement results that hold up to DeKalb conditions year after year.
From inspection to completion, here is how we deliver professional roof replacement 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.

Real feedback from property owners who trusted Lapolla Industries with their spray foam projects.
"Our corrugated metal roof was rusting at every fastener and seam. They cleaned the entire surface, treated the rust, and applied a thick elastomeric coating. The roof looks brand new and is completely sealed now."
"We manage a 40,000 square foot retail center and the roof was near end of life. Instead of tearing it off they restored it with a spray foam and coating system. Saved us over sixty percent versus replacement and added twenty years of life."
"We needed our concrete roof deck waterproofed before installing new equipment on it. The crew applied a monolithic membrane that handles foot traffic and ponding water. Two years in and zero issues. Money well spent."
