Professional SPF roof installation, coating, and insulation in Alton, NH. Free inspections. Call today for a no-obligation estimate.
Comprehensive spray foam roofing and insulation services tailored for Alton properties.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
From minor surface patches to full-section refoaming and recoating, our repair crews restore SPF roof performance using materials compatible with your existing system. Every repair is blended seamlessly and warranted.
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.
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.
Emergency storm damage response with tarping, property protection, detailed damage documentation for insurance, and complete roof restoration to pre-storm condition. We work directly with insurance adjusters.

Answers to the most frequently asked spray foam questions from Alton property owners.
Spray foam insulation costs in Alton 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 Alton homeowners see a full return on investment through energy savings within 3 to 5 years.
If your commercial roof in Alton is structurally sound but showing surface deterioration — cracked coatings, minor leaks, UV damage — restoration with SPF and a new coating system is likely the better investment. If there is widespread substrate damage, saturated insulation, or structural concerns, full replacement may be necessary. Our inspection will determine which option is right.
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 Alton homes with persistent crawl space moisture issues, closed-cell foam combined with vapor barrier encapsulation provides a permanent solution.
Spray foam is one of the best solutions for flat and low-slope roofs in Alton. 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.
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 Alton crews evaluate the existing substrate to ensure it is structurally sound before application.
Most residential attic insulation projects in Alton 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.
Our reputation is built on results. Here is what our customers say.
"Lapolla Industries waterproofed our commercial building after we had recurring moisture issues. They applied a spray foam base with a silicone topcoat and the building has been completely dry since. Outstanding results."
"Our 18-year-old roof was showing its age but still structurally sound. Lapolla Industries recommended restoration over replacement and it was the right call. New coating, sealed seams, and a 15-year warranty. Smart investment."
"Called about a ceiling stain that kept growing. They got on the roof, found the leak source at a HVAC curb penetration, and had it sealed within hours. Professional, fast, and the price was exactly what they quoted."
