Denville's trusted spray foam contractor for commercial roofing, residential insulation, and emergency roof repair across New Jersey.
Professional roofing, coating, and insulation services for Denville property owners and facility managers.
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.
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.
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.
Large-scale commercial roof restoration using SPF and coating systems that extend roof life by 20 or more years without the cost and disruption of full replacement. Phased scheduling available to keep your business operational.
Cold floors, musty smells, and high energy bills often trace back to an uninsulated or poorly insulated crawl space. Our closed-cell spray foam seals the entire crawl space envelope — walls, rim joists, and sill plates — creating a conditioned space.
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.
Transform your building with a spray foam roof that insulates, waterproofs, and strengthens in a single application. No tear-off required over most existing substrates. Backed by manufacturer warranties and our own workmanship guarantee.
Stop metal roof leaks without replacement. Our elastomeric coating system treats rust, seals every fastener and seam, and creates a continuous waterproof membrane over your entire metal roof — backed by a manufacturer warranty.
Our maintenance programs extend roof life and reduce total cost of ownership. Semi-annual or annual visits include drain clearing, seam inspection, penetration checks, coating condition assessment, and immediate repair of minor issues.
Comprehensive roof inspections using infrared moisture scanning, core sampling, and visual assessment. Detailed photo-documented reports with condition ratings, remaining life estimates, and prioritized repair recommendations.
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.
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.
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.
Our replacement process is thorough: remove existing roofing to the deck, inspect and repair substrate, apply closed-cell SPF to specified thickness, and finish with a UV-protective coating. The result is a monolithic roof system with no seams to fail.
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.
Denville, NJ is home to a growing mix of commercial, industrial, and residential properties — and Lapolla Industries serves all of them with professional spray foam roofing and insulation. Our SPF systems are particularly effective for the flat-roofed commercial buildings common in Denville, where conventional membrane roofs develop seam failures and ponding issues within years of installation.

No separate vapor barrier. No separate insulation board. No seams to fail. Just one seamless, self-adhering membrane that protects your Denville investment for decades.

Answers to the most frequently asked spray foam questions from Denville property owners.
Spray foam insulation costs in Denville 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 Denville homeowners see a full return on investment through energy savings within 3 to 5 years.
A properly installed SPF roof in Denville 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.
Yes. Spray foam applied to crawl space walls and rim joists creates an airtight moisture barrier that eliminates condensation, musty odors, and cold floors. For Denville homes with persistent crawl space moisture issues, closed-cell foam combined with vapor barrier encapsulation provides a permanent solution.
Silicone roof coatings offer the longest service life for flat and low-slope roofs in Denville. 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 Denville roof with drainage challenges or heavy weather exposure.
In most cases, yes. One of the biggest advantages of SPF roofing is that it can be applied directly over existing roof membranes — TPO, EPDM, built-up, and even metal — without a costly tear-off. Our Denville crews evaluate the existing substrate to ensure it is structurally sound before application.
Absolutely. SPF roofing performs exceptionally in both extremes because the closed-cell foam provides continuous insulation without thermal bridging. In hot Denville summers, the reflective coating reduces surface temperatures by up to 50 degrees. In winter, the insulation value keeps conditioned air inside.
Real reviews from property owners we have served across the country.
"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."
"Our corrugated metal roof was rusting at every fastener and seam. They cleaned the entire surface, treated the rust, and applied a thick elastomeric coating. The roof looks brand new and is completely sealed now."
"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."
