Professional SPF roof installation, coating, and insulation in Stratham, NH. Free inspections. Call today for a no-obligation estimate.
Comprehensive spray foam roofing and insulation services tailored for Stratham properties.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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 Stratham property owners.
Spray foam is one of the best solutions for flat and low-slope roofs in Stratham. 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.
Most residential attic insulation projects in Stratham 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.
Spray foam insulation costs in Stratham 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 Stratham homeowners see a full return on investment through energy savings within 3 to 5 years.
A properly installed SPF roof in Stratham 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. Spray foam applied to crawl space walls and rim joists creates an airtight moisture barrier that eliminates condensation, musty odors, and cold floors. For Stratham homes with persistent crawl space moisture issues, closed-cell foam combined with vapor barrier encapsulation provides a permanent solution.
If your commercial roof in Stratham 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.
Our reputation is built on results. Here is what our customers say.
"Our metal warehouse roof had been leaking at the ridge and sidewall transitions for years. The coating crew sealed every penetration, fastener, and seam. Completely watertight now and the energy savings are a great bonus."
"Our corrugated metal roof was rusting at every fastener and seam. They cleaned the entire surface, treated the rust, and applied a thick elastomeric coating. The roof looks brand new and is completely sealed now."
"Had spray foam applied to our crawl space walls and rim joists. The difference in floor temperature upstairs is dramatic. Our furnace cycles less and the energy savings paid for the project faster than they estimated."
