Expert flat roof repair in Montclair, NJ. Licensed spray foam contractors with manufacturer-backed warranties and free inspections.
If your flat roof in Montclair has been repaired multiple times and still leaks, the problem is likely systemic — failed seam adhesive, deteriorated flashing, or inadequate drainage slope. Our NJ crews identify these underlying issues and resolve them permanently using spray foam and liquid-applied membrane systems.
The buildings and homes of Montclair, NJ 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 flat roof repair solutions using closed-cell spray polyurethane foam that outperforms conventional materials in every measurable category.
Our Montclair 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 Montclair property owners rely on to deliver it right.
From inspection to completion, here is how we deliver professional flat roof repair results.
Before any work begins, our certified inspectors evaluate your property and provide a comprehensive assessment including current condition, repair needs, and recommended SPF solutions. You get a written estimate with no hidden fees.
Proper surface preparation is critical for spray foam adhesion and long-term performance. Our crews clean, dry, and prime all surfaces, remove debris and loose material, and ensure the substrate meets manufacturer specifications before any foam is applied.
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.
We finish every project with the appropriate protective coating, thorough cleanup, and a detailed walkthrough. You receive project documentation including photos, material specifications, warranty registration, and maintenance recommendations.

"We chose silicone over acrylic for our flat roof recoat and it was the right decision. Handles ponding water without softening and the UV resistance is excellent. Lapolla Industries recommended the right product for our situation."
"We had a persistent leak that three different contractors could not find. Their team used moisture scanning equipment and pinpointed it to a failed pipe boot in minutes. Fixed it the same day. Incredible diagnostic work."
"Our old three-layer built-up roof was beyond saving. They stripped everything down to the deck, repaired the substrate, and installed a new spray foam roofing system. The building is better insulated now than it has ever been."
