Professional SPF roof installation, coating, and insulation in Sandown, NH. Free inspections. Call today for a no-obligation estimate.
Full-spectrum spray foam solutions for residential and commercial buildings in Sandown, NH.
Seamless waterproofing membranes applied over existing roof surfaces to eliminate leaks and ponding water permanently. Our spray-applied systems conform to every detail and create a monolithic barrier with no seams to fail.
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.
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.
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.
Full roof replacement with spray polyurethane foam delivers superior insulation, waterproofing, and wind uplift resistance compared to conventional membrane systems. We strip the old roof, inspect the deck, and install a new SPF system built for decades.
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.
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.
Precision leak detection and permanent repair for active roof leaks. We use infrared moisture scanning and visual inspection to trace the leak to its source, then apply a lasting fix — not a band-aid — so it never comes back.
Attic insulation with spray foam delivers the highest R-value per inch and eliminates the air infiltration that accounts for up to 40 percent of your home energy waste. Our crews install cleanly and efficiently — in and out in one day.
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.
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.
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.
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.
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 restoration saves 50 to 70 percent compared to full replacement while delivering equivalent performance. Our SPF and coating systems seal every seam, add insulation value, and provide a reflective finish that cuts cooling costs.

Answers to the most frequently asked spray foam questions from Sandown property owners.
A properly installed SPF roof in Sandown 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. Every project in Sandown 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. There is never a charge for the initial inspection.
Yes. Spray foam applied to crawl space walls and rim joists creates an airtight moisture barrier that eliminates condensation, musty odors, and cold floors.

"Called about cracks forming in our spray foam roof coating. Lapolla Industries came out, assessed the damage, and recoated the affected areas. The repair blended seamlessly with the existing surface. Fair pricing too."
"We needed our concrete roof deck waterproofed before installing new equipment on it. The crew applied a monolithic membrane that handles foot traffic and ponding water. Two years in and zero issues. Money well spent."
