Exeter's trusted spray foam contractor for commercial roofing, residential insulation, and emergency roof repair across New Hampshire.
Professional roofing, coating, and insulation services for Exeter property owners and facility managers.
Flat roofs fail at seams, flashings, and penetrations. Our crews specialize in diagnosing and repairing these critical failure points using spray foam, liquid-applied membranes, and targeted coating systems that outlast conventional patch repairs.
Waterproof your flat or low-slope roof with a spray-applied membrane system that eliminates the seam failures, flashing leaks, and ponding damage that plague conventional roofing. One seamless application. Permanent results.
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.
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.
When your roof is structurally sound but the surface is deteriorating, restoration is the smart investment. We clean, repair, and recoat your entire roof with a warranted system that performs like new at a fraction of replacement cost.
Upgrade your attic insulation from fiberglass or cellulose to spray foam and feel the difference the same day. SPF does not settle, sag, or leave gaps — it expands to fill every cavity and seals air leaks that other materials miss.
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.
Active roof leak? We locate the source using advanced detection methods, then repair it permanently at the root cause. No guesswork, no temporary patches — just lasting results backed by our workmanship warranty.
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.
Our commercial restoration process preserves your existing roof structure, adds insulation value, and applies a warranted waterproof coating system — saving 50 to 70 percent versus tear-off and replacement on buildings of any size.
Extend the life of your existing roof by 15 to 20 years with a silicone coating that seals every seam, reflects solar heat, and handles ponding water without softening or deteriorating. Professional application with manufacturer warranty.
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.
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.
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.
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.
Exeter, NH 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 Exeter, where conventional membrane roofs develop seam failures and ponding issues within years of installation.
For Exeter facility managers and building owners, spray foam offers something no other roofing system can: a single application that provides waterproofing, insulation, and structural reinforcement simultaneously. No separate vapor barrier. No separate insulation board. No seams to fail. Just one seamless, self-adhering membrane that protects your Exeter investment for decades.
We are committed to delivering exceptional spray foam solutions that protect your biggest investment.
No hidden fees, no surprise charges. You receive a detailed written estimate before we start and the final invoice matches — guaranteed. Every line item explained.

Unlike conventional roofing with seams, joints, and fasteners, spray foam creates a monolithic membrane with zero penetration points — eliminating the most common sources of roof leaks.

A properly installed SPF roof in Exeter 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 Exeter homes with persistent crawl space moisture issues, closed-cell foam combined with vapor barrier encapsulation provides a permanent solution.
Yes. Every project in Exeter begins with a no-obligation roof inspection. Our crews assess the condition of your existing roof, identify problem areas using infrared moisture scanning when needed, and provide a detailed estimate with photos and recommendations.

Spray foam insulation costs in Exeter 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 Exeter homeowners see a full return on investment through energy savings within 3 to 5 years.
Absolutely. SPF roofing performs exceptionally in both extremes because the closed-cell foam provides continuous insulation without thermal bridging. In hot Exeter summers, the reflective coating reduces surface temperatures by up to 50 degrees. In winter, the insulation value keeps conditioned air inside.
