Northfield's trusted spray foam contractor for commercial roofing, residential insulation, and emergency roof repair across New Jersey.
From SPF roof installation to attic insulation, Lapolla Industries covers every spray foam need in Northfield.
Ponding water, chronic leaks, and moisture infiltration destroy roofs and building interiors. Our waterproofing systems use closed-cell spray foam and silicone coatings to create an impermeable barrier that handles standing water indefinitely.
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.
Expert repair for existing SPF roofs including blistering, coating deterioration, punctures, and storm damage. We restore your foam roof to like-new condition with matching materials and factory-specified application techniques.
Roof leaks get worse with every rain. Our crews respond fast, identify the exact source using infrared and moisture mapping, and apply permanent repairs using spray foam and coating systems designed for long-term performance.
Hail, wind, and debris damage demand immediate attention and thorough documentation. Our crews respond quickly, document all damage with photos and measurements that satisfy insurance adjusters, and restore your roof completely.
Stop chasing flat roof leaks with temporary fixes. Our diagnostic approach pinpoints the exact failure point, and our repair methods address the root cause — whether it is failed flashing, membrane damage, or ponding water that needs re-sloping.
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.
Silicone coatings provide the longest service life of any roof coating product. Our crews apply them over metal, TPO, EPDM, built-up, and spray foam surfaces — sealing the entire roof in a seamless, reflective, waterproof membrane.
Closed-cell and open-cell spray foam attic insulation that eliminates air infiltration and creates a continuous thermal barrier from ridge to eave. Most projects completed in a single day with immediate comfort improvement.
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.
Complete roof restoration with spray foam and protective coatings that add 20 or more years of life to your existing roof — without the cost, waste, and disruption of a full tear-off and replacement.
Preventive roof maintenance programs with scheduled inspections, drain cleaning, minor repairs, and detailed photo-documented condition reports. Catch small problems before they become expensive emergencies.
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.
Pre-purchase, post-storm, or routine maintenance — our inspection reports give you the data you need to make informed decisions about your roof. Infrared moisture scans reveal trapped water invisible from the surface.
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.
Even in a community the size of Northfield, NJ, commercial buildings, warehouses, and agricultural structures need the same high-performance roofing and insulation as facilities in major metros. Lapolla Industries provides spray foam solutions engineered for New Jersey conditions — from metal building insulation to flat roof waterproofing — at a price point that makes sense for Northfield businesses.
Our Northfield crews specialize in spray foam applications that conventional roofers simply cannot do: re-sloping flat roofs to eliminate ponding, insulating metal buildings from the inside out, and restoring aging commercial roofs without the cost and disruption of a full tear-off. If your Northfield building has a roof problem, we have a spray foam solution.

Common questions about spray foam roofing and insulation in Northfield, NJ.
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 Northfield we typically recommend closed-cell for its waterproofing properties. For interior wall insulation, either type may be appropriate.
Call us immediately for emergency tarping to prevent further water damage. Our Northfield storm damage crews respond quickly to secure your property, document all damage with photos and measurements for your insurance claim, and provide a complete restoration plan. We work directly with insurance adjusters to ensure your claim is handled smoothly.
Spray foam insulation costs in Northfield typically range from $1.50 to $3.50 per square foot for open-cell and $3.00 to $7.00 per square foot for closed-cell. The exact price depends on the area being insulated, foam thickness, and accessibility. Most Northfield homeowners see a full return on investment through energy savings within 3 to 5 years.
Yes. Every Northfield crew is fully licensed, bonded, and insured for spray foam roofing and insulation work. We carry general liability and workers compensation coverage on every project. You can request proof of insurance before any work begins.
Spray foam is one of the best solutions for flat and low-slope roofs in Northfield. 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 Northfield. 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 Northfield roof with drainage challenges or heavy weather exposure.
Real reviews from property owners we have served across the country.
"Ponding water on our flat roof was causing constant problems. They re-sloped the low spots with tapered foam and applied a silicone coating. No more standing water after rain. Excellent work."
"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."
"Lapolla Industries insulated our crawl space with spray foam and encapsulated the entire area. No more cold floors in winter, no more musty smell. The crew worked in tight quarters and did an excellent job. Very impressed."
