Expert spray foam roofing in Denville, NJ. Licensed spray foam contractors with manufacturer-backed warranties and free inspections.
A spray foam roof installed by Lapolla Industries in Denville creates a monolithic membrane that bonds directly to your existing roof deck — no mechanical fasteners, no seam tape, no adhesive. The result is a roof with zero penetration points and the highest insulation value per inch of any roofing system available.
When Denville, NJ property owners need spray foam roofing, 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 Denville crews have seen every spray foam roofing scenario New Jersey weather can create. We use that experience to select the right foam type, coating system, and application method for your specific property — delivering spray foam roofing results that hold up to Denville conditions year after year.
From inspection to completion, here is how we deliver professional spray foam roofing results.
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.

Our reputation is built on results. Here is what our customers have to say.
"Lapolla Industries repaired our flat roof after a section of the membrane started bubbling and lifting. They removed the damaged area, applied new substrate, and sealed everything tight. Solid repair at a fair price."
"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 our entire warehouse roof restored with a spray-applied coating system. The crew worked around our operations without any disruption. The finished roof reflects heat beautifully and our AC runs less. Win-win."
