Expert roof leak repair in Dover, NY. Licensed spray foam contractors with manufacturer-backed warranties and free inspections.
Roof leaks in Dover buildings often originate far from where the water shows up inside. Lapolla Industries uses infrared moisture scanning to trace the leak path across your roof assembly and pinpoint the exact entry point — whether it is a failed pipe boot, deteriorated flashing, or a membrane breach invisible from the surface.
When Dover, NY property owners need roof leak repair, 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 Dover crews have seen every roof leak repair scenario New York weather can create. We use that experience to select the right foam type, coating system, and application method for your specific property — delivering roof leak repair results that hold up to Dover conditions year after year.
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.
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.
Our factory-trained crews apply spray polyurethane foam using calibrated equipment that ensures consistent thickness, proper density, and complete coverage. The foam expands on contact, fills every gap, and bonds permanently to the prepared substrate.
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.

"When our TPO roof failed after only eight years we switched to spray foam for the replacement. The seamless application eliminates all the seam failures that plagued the old system. Three years in and it performs flawlessly."
"Had a few spots where birds had pecked through the coating on our foam roof. The repair crew patched every spot and applied a fresh topcoat over the entire section. Looks brand new and no more leaks."
"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."
