Expert roof waterproofing in Decatur, AL. Licensed spray foam contractors with manufacturer-backed warranties and free inspections.
Ponding water destroys conventional roof waterproofing because standing water attacks seams and coating adhesion. Our SPF-based waterproofing systems in Decatur are engineered to handle indefinite ponding — the silicone topcoat does not re-emulsify, soften, or deteriorate in standing water.
When Decatur, AL 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 Decatur crews have seen every roof waterproofing scenario Alabama 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 Decatur conditions year after year.
How our certified crews deliver precision roof waterproofing in Decatur, AL.
Every project begins with a thorough inspection of your property. We evaluate the existing condition, identify problem areas, and use infrared moisture scanning when needed to reveal hidden issues. You receive a detailed report with photos and honest recommendations.
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.
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.
After the foam cures, we apply a UV-protective coating — silicone, acrylic, or elastomeric — selected for your specific application and climate. We then remove all masking, clean up the work area, and conduct a final walkthrough with you to verify satisfaction.

"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."
