Professional roof waterproofing for Sudbury property owners. Lapolla Industries delivers lasting results with industry-leading SPF technology.
Ponding water destroys conventional roof waterproofing because standing water attacks seams and coating adhesion. Our SPF-based waterproofing systems in Sudbury are engineered to handle indefinite ponding — the silicone topcoat does not re-emulsify, soften, or deteriorate in standing water.
In Sudbury, MA, the difference between a spray foam job that lasts and one that fails comes down to the contractor. Lapolla Industries applies the same quality standards to every roof waterproofing project that earned us a reputation as one of the nation's most trusted SPF specialists — proper surface prep, correct foam thickness, and factory-specified coating application.
Every roof waterproofing project we complete in Sudbury is backed by both manufacturer material warranties and our own workmanship guarantee. We document every step with photos and measurements, provide you with a detailed project report, and remain available for warranty service and maintenance throughout the life of your SPF system.
Our proven process ensures quality results on every spray foam project.
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.

"Had silicone roof coating applied to our office building. The crew was professional and the finish is smooth and uniform. Energy savings have been noticeable on our monthly bills. Would recommend for any flat or low-slope roof."
"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 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."
