Trusted spray foam roofing & insulation services for Portsmouth, NH property owners. Licensed, insured, and backed by manufacturer warranties.
From SPF roof installation to attic insulation, Lapolla Industries covers every spray foam need in Portsmouth.
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.
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.
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.
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.
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.
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 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.
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.
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.
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.
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.
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.
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.
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.
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.
Portsmouth, 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 Portsmouth, where conventional membrane roofs develop seam failures and ponding issues within years of installation.
For Portsmouth 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 Portsmouth investment for decades.

Have questions about spray foam in Portsmouth? We have answers.
Yes. Every Portsmouth 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.
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 Portsmouth crews evaluate the existing substrate to ensure it is structurally sound before application.
Spray foam is one of the best solutions for flat and low-slope roofs in Portsmouth. 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 Portsmouth. 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 Portsmouth roof with drainage challenges or heavy weather exposure.
A properly installed SPF roof in Portsmouth 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.
Most residential attic insulation projects in Portsmouth 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.
Honest feedback from property owners who trusted Lapolla Industries with their spray foam projects.
"Water was coming in around our skylight every time it rained. Lapolla Industries traced it to deteriorated sealant and improper flashing. They redid everything and we have been bone dry through two heavy storm seasons now."
"Regular maintenance visits twice a year keep our flat roof in great shape. They clean drains, check seams, inspect all penetrations, and send a detailed report with photos. Good preventive program at a reasonable cost."
"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."
