Trusted roof waterproofing in Williston, ND. Our certified crews deliver precision workmanship and guaranteed results.
Ponding water destroys conventional roof waterproofing because standing water attacks seams and coating adhesion. Our SPF-based waterproofing systems in Williston are engineered to handle indefinite ponding — the silicone topcoat does not re-emulsify, soften, or deteriorate in standing water.
When Williston, ND 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 Williston crews have seen every roof waterproofing scenario North Dakota 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 Williston conditions year after year.
From inspection to completion, here is how we deliver professional roof waterproofing results.
Before any work begins, our certified inspectors evaluate your property and provide a comprehensive assessment including current condition, repair needs, and recommended SPF solutions. You get a written estimate with no hidden fees.
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.
Using precision spray equipment, our crews apply the foam in controlled passes to achieve the specified thickness and density. The closed-cell foam expands 30 to 40 times its liquid volume, conforming to every detail of the surface and creating a seamless monolithic barrier.
We finish every project with the appropriate protective coating, thorough cleanup, and a detailed walkthrough. You receive project documentation including photos, material specifications, warranty registration, and maintenance recommendations.

Real feedback from property owners who trusted Lapolla Industries with their spray foam projects.
"We signed up for their annual roof maintenance program for our three commercial buildings. They catch small issues before they become expensive repairs. Last inspection they found a failing pipe boot that would have caused a major leak."
"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."
