Professional flat roof repair for Rockville property owners. Lapolla Industries delivers lasting results with industry-leading SPF technology.
If your flat roof in Rockville has been repaired multiple times and still leaks, the problem is likely systemic — failed seam adhesive, deteriorated flashing, or inadequate drainage slope. Our MD crews identify these underlying issues and resolve them permanently using spray foam and liquid-applied membrane systems.
In Rockville, MD, 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 flat roof repair 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 flat roof repair project we complete in Rockville 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.

Honest reviews from property owners who chose Lapolla Industries for their roofing and insulation needs.
"Had spray foam applied to our crawl space walls and rim joists. The difference in floor temperature upstairs is dramatic. Our furnace cycles less and the energy savings paid for the project faster than they estimated."
"Our 18-year-old roof was showing its age but still structurally sound. Lapolla Industries recommended restoration over replacement and it was the right call. New coating, sealed seams, and a 15-year warranty. Smart investment."
