Professional roofing, coating, and insulation services for Merrimack property owners and facility managers.
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.
Roof leaks get worse with every rain. Our crews respond fast, identify the exact source using infrared and moisture mapping, and apply permanent repairs using spray foam and coating systems designed for long-term performance.
Comprehensive roof inspections using infrared moisture scanning, core sampling, and visual assessment. Detailed photo-documented reports with condition ratings, remaining life estimates, and prioritized repair recommendations.
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.
Complete roof restoration with spray foam and protective coatings that add 20 or more years of life to your existing roof — without the cost, waste, and disruption of a full tear-off and replacement.
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.
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.
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.
Closed-cell and open-cell spray foam attic insulation that eliminates air infiltration and creates a continuous thermal barrier from ridge to eave. Most projects completed in a single day with immediate comfort improvement.
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.
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.
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.
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.
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.
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.

Common questions about spray foam roofing and insulation in Merrimack, NH.
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 Merrimack homes with persistent crawl space moisture issues, closed-cell foam combined with vapor barrier encapsulation provides a permanent solution.
Yes. Every project in Merrimack 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.
Spray foam insulation costs in Merrimack 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 Merrimack homeowners see a full return on investment through energy savings within 3 to 5 years.
Spray foam is one of the best solutions for flat and low-slope roofs in Merrimack. 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 Merrimack crews evaluate the existing substrate to ensure it is structurally sound before application.
Yes. Spray foam roofing provides the highest R-value per inch of any commercial roofing insulation — typically R-6.5 per inch. In Merrimack, 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.
