Trusted roof leak repair in Cranford, NJ. Our certified crews deliver precision workmanship and guaranteed results.
Three contractors tried to fix this leak and failed — that is what we hear from Cranford property owners every week. The difference with Lapolla Industries is our diagnostic approach: we do not guess where the leak is. We use infrared scanning and moisture mapping to see it, then fix it at the source.
The buildings and homes of Cranford, 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 roof leak repair solutions using closed-cell spray polyurethane foam that outperforms conventional materials in every measurable category.
Our Cranford 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 Cranford property owners rely on to deliver it right.
From inspection to completion, here is how we deliver professional roof leak repair results.
Our assessment process goes beyond a visual check. We examine substrate conditions, drainage patterns, existing insulation performance, and structural integrity. This data-driven approach ensures we recommend the right spray foam solution for your specific property.
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.
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.
The final step is applying a protective topcoat that shields the SPF from UV exposure and provides the weather surface. We select the coating type based on your roof slope, ponding conditions, and desired service life. After coating, we clean up completely and review the finished project with you.

Real feedback from property owners who trusted Lapolla Industries with their spray foam projects.
