Trusted roof waterproofing in Raleigh, NC. Our certified crews deliver precision workmanship and guaranteed results.
Waterproofing a roof in Raleigh, NC requires more than paint-on products that peel and crack. Lapolla Industries applies spray foam and elastomeric membranes that create a true monolithic waterproof barrier — no seams, no joints, no weak points where North Carolina rain can find a path inside.
When Raleigh, NC property owners need roof waterproofing, 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 Raleigh crews have seen every roof waterproofing scenario North Carolina weather can create. We use that experience to select the right foam type, coating system, and application method for your specific property — delivering roof waterproofing results that hold up to Raleigh conditions year after year.
From inspection to completion, here is how we deliver professional roof waterproofing 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.

Real feedback from property owners who trusted Lapolla Industries with their spray foam projects.
"Had our attic insulated with spray foam after years of fiberglass that kept settling and losing its R-value. Lapolla Industries did a clean install — no gaps, no missed spots. Our HVAC system runs half as much now."
"Full roof replacement on our 12,000 square foot commercial building. Lapolla Industries removed the old single-ply membrane and installed spray foam with a silicone topcoat. Clean work, professional crew, and a 20-year warranty."
"The silicone coating they applied to our metal roof eliminated all the rust spots and sealed every seam and fastener. The reflective finish dropped our cooling costs noticeably. Our building looks ten years newer."
