Dunellen's trusted spray foam contractor for commercial roofing, residential insulation, and emergency roof repair across New Jersey.
Professional roofing, coating, and insulation services for Dunellen property owners and facility managers.
Roof restoration saves 50 to 70 percent compared to full replacement while delivering equivalent performance. Our SPF and coating systems seal every seam, add insulation value, and provide a reflective finish that cuts cooling costs.
Spray foam roofs are built to last, but they do need occasional repair. Our crews fix bird pecks, foot traffic damage, hail impacts, and coating wear — extending the life of your SPF system without a costly full recoat.
Full roof replacement with spray polyurethane foam delivers superior insulation, waterproofing, and wind uplift resistance compared to conventional membrane systems. We strip the old roof, inspect the deck, and install a new SPF system built for decades.
Elastomeric coatings for standing seam, corrugated, and R-panel metal roofs. We seal rust spots, failing fasteners, open seams, and ridge caps — stopping leaks and adding reflective energy savings in a single application.
When severe weather damages your roof, our storm response crews deploy fast — securing your property, documenting every impact point for your insurance claim, and restoring your roof with quality materials and expert workmanship.
Know the true condition of your roof before problems escalate. Our inspection process covers every component — membrane, flashings, penetrations, drains, and substrate — and delivers a clear, actionable report you can trust.
New spray polyurethane foam roof installation that creates a seamless, self-adhering membrane with the highest R-value per inch of any roofing system. Energy-efficient, leak-proof, and engineered to last 30 to 50 years with periodic recoating.
Precision leak detection and permanent repair for active roof leaks. We use infrared moisture scanning and visual inspection to trace the leak to its source, then apply a lasting fix — not a band-aid — so it never comes back.
Commercial roofs deteriorate from the surface down. If your structure and deck are sound, restoration with spray foam and silicone coating is the economically superior choice. We handle buildings from 5,000 to 500,000 square feet.
Attic insulation with spray foam delivers the highest R-value per inch and eliminates the air infiltration that accounts for up to 40 percent of your home energy waste. Our crews install cleanly and efficiently — in and out in one day.
Professional flat roof repair for all membrane types — TPO, EPDM, modified bitumen, built-up, and PVC. We find the actual source of the leak using infrared scanning and fix it permanently, not with another temporary patch.
Protect your roofing investment with a maintenance program designed for your specific roof type. Our crews document every visit with photos and condition ratings so you always know the exact state of your roof.
Spray foam insulation for crawl space walls, rim joists, and band boards that eliminates moisture, cold floors, and musty odors. Closed-cell foam acts as both insulation and vapor barrier in a single application.
Seamless waterproofing membranes applied over existing roof surfaces to eliminate leaks and ponding water permanently. Our spray-applied systems conform to every detail and create a monolithic barrier with no seams to fail.
High-performance silicone roof coatings that resist ponding water, UV degradation, and extreme temperatures. Unlike acrylics, silicone does not re-emulsify in standing water — making it ideal for flat roofs with drainage challenges.

Common questions about spray foam roofing and insulation in Dunellen, NJ.
A properly installed SPF roof in Dunellen can last 30 to 50 years with periodic recoating every 10 to 15 years. The closed-cell foam itself does not degrade — only the protective topcoat needs maintenance. Many spray foam roofs installed in the 1970s are still performing today.
Absolutely. SPF roofing performs exceptionally in both extremes because the closed-cell foam provides continuous insulation without thermal bridging. In hot Dunellen summers, the reflective coating reduces surface temperatures by up to 50 degrees. In winter, the insulation value keeps conditioned air inside.
Spray foam is one of the best solutions for flat and low-slope roofs in Dunellen. The seamless application eliminates the seams and joints where conventional flat roof systems fail. SPF also self-levels to eliminate ponding water — one of the biggest causes of flat roof leaks and premature failure.
Silicone roof coatings offer the longest service life for flat and low-slope roofs in Dunellen. Unlike acrylic coatings, silicone does not re-emulsify in ponding water and maintains its flexibility and UV resistance for 15 to 20 years. We recommend silicone for any Dunellen roof with drainage challenges or heavy weather exposure.
Closed-cell foam is denser, provides a higher R-value per inch (R-6.5 vs R-3.7), and acts as a vapor and moisture barrier. Open-cell foam is lighter, more flexible, and more affordable. For roofing applications in Dunellen we typically recommend closed-cell for its waterproofing properties. For interior wall insulation, either type may be appropriate.
Most residential attic insulation projects in Dunellen are completed in a single day. Our crews prep the space, apply the spray foam to the desired thickness, and clean up within 6 to 8 hours. The foam cures within minutes, and you can feel the difference in your home comfort levels the same day.

"Lapolla Industries waterproofed our commercial building after we had recurring moisture issues. They applied a spray foam base with a silicone topcoat and the building has been completely dry since. Outstanding results."
"Lapolla Industries installed a spray foam roof on our warehouse last spring. Their crew was thorough, professional, and finished ahead of schedule. The building stays cooler in summer and the roof looks pristine a year later."
"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."
