Trusted spray foam roofing & insulation services for Goffstown, NH property owners. Licensed, insured, and backed by manufacturer warranties.
Professional roofing, coating, and insulation services for Goffstown property owners and facility managers.
Metal roofs leak at fasteners, seams, and panel overlaps. Our coating systems bridge and seal every one of these failure points while adding a reflective finish that reduces surface temperatures and cooling costs significantly.
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.
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.
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 SPF roof systems for commercial and residential buildings. Our factory-trained crews apply closed-cell foam directly to your roof deck, creating a monolithic waterproof membrane that eliminates seams, joints, and the leak points they create.
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.
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.
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.
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.
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.
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.
Transform your crawl space from a moisture liability into a conditioned, energy-efficient part of your building envelope. Spray foam eliminates condensation, prevents mold conditions, and dramatically improves floor comfort above.
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.
When restoration is not enough, our crews perform complete roof tear-off and replacement with modern spray foam roofing systems. Full deck inspection, substrate repair, SPF application, and protective coating — all warranted.
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.

Answers to the most frequently asked spray foam questions from Goffstown property owners.
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 Goffstown we typically recommend closed-cell for its waterproofing properties. For interior wall insulation, either type may be appropriate.
Absolutely. SPF roofing performs exceptionally in both extremes because the closed-cell foam provides continuous insulation without thermal bridging. In hot Goffstown summers, the reflective coating reduces surface temperatures by up to 50 degrees. In winter, the insulation value keeps conditioned air inside.
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 Goffstown homes with persistent crawl space moisture issues, closed-cell foam combined with vapor barrier encapsulation provides a permanent solution.
Yes. Spray foam roofing provides the highest R-value per inch of any commercial roofing insulation — typically R-6.5 per inch. In Goffstown, this translates to significant cooling and heating savings because the seamless membrane eliminates air infiltration that accounts for up to 40 percent of energy loss in conventional roofs.
Spray foam is one of the best solutions for flat and low-slope roofs in Goffstown. 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 Goffstown. 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 Goffstown roof with drainage challenges or heavy weather exposure.
Honest feedback from property owners who trusted Lapolla Industries with their spray foam projects.
"They waterproofed our entire flat roof with a seamless elastomeric membrane. Two years later and not a single drop of water has gotten through. The application was clean and fast — three days for 8,000 square feet."
"Got a comprehensive inspection done on our warehouse roof. They found three areas of trapped moisture that were invisible from the surface. The early detection saved us from much more expensive structural repairs down the road."
"Lapolla Industries repaired our flat roof after a section of the membrane started bubbling and lifting. They removed the damaged area, applied new substrate, and sealed everything tight. Solid repair at a fair price."
