Expert roof waterproofing in Valley Stream, NY. Licensed spray foam contractors with manufacturer-backed warranties and free inspections.
For Valley Stream property owners dealing with chronic roof moisture problems, our waterproofing approach starts with diagnosis — we identify where water enters and why it ponds — then we apply a seamless SPF membrane that solves both problems permanently.
The buildings and homes of Valley Stream, NY face unique challenges — from seasonal temperature extremes to storm exposure — that demand roofing and insulation systems built for performance, not just price. Lapolla Industries delivers roof waterproofing solutions using closed-cell spray polyurethane foam that outperforms conventional materials in every measurable category.
Our Valley Stream customers see the difference in their energy bills, their comfort levels, and the longevity of their roofing systems. Spray foam does not degrade like fiberglass, does not develop seam failures like TPO, and does not crack like built-up roofing. It is a permanent solution — and Lapolla Industries is the permanent partner Valley Stream property owners rely on to deliver it right.
How our certified crews deliver precision roof waterproofing in Valley Stream, NY.
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.
We prepare every surface according to factory guidelines — cleaning contaminants, addressing moisture, repairing damaged substrate, and verifying adhesion conditions. This step is not glamorous, but it is the foundation of a spray foam system that lasts decades.
Application is performed by certified spray foam technicians using the latest proportioning equipment. We monitor foam temperature, pressure, and ratio throughout application to ensure every square foot meets manufacturer performance specifications.
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.

Our reputation is built on results. Here is what our customers have to say.
"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."
"Attic insulation upgrade from blown-in to spray foam. The crew masked everything off properly and the overspray was minimal. The temperature in our attic dropped dramatically and so did our energy bills. Worth the investment."
"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."
