Spray Foam Services in St. Johnsbury

Full-spectrum spray foam solutions for residential and commercial buildings in St. Johnsbury, VT.

Roof Restoration

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.

Roof Leak Repair

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.

Spray Foam Roofing

New spray polyurethane foam roof installation that creates a seamless, self-adhering membrane with the highest R-value per inch of any roofing system. Energy-efficient, leak-proof, and engineered to last 30 to 50 years with periodic recoating.

Metal Roof Coating

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.

Silicone Roof Coating

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.

Commercial Roof Restoration

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.

Crawl Space Insulation

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.

Spray Foam Roofing Repair

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.

Roof Replacement

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.

Roof Inspection

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.

Storm Damage Roof Repair

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.

Roof Waterproofing

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.

Flat Roof Repair

Stop chasing flat roof leaks with temporary fixes. Our diagnostic approach pinpoints the exact failure point, and our repair methods address the root cause — whether it is failed flashing, membrane damage, or ponding water that needs re-sloping.

Attic Insulation

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.

Roof Maintenance

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.

Frequently Asked Questions

Have questions about spray foam in St. Johnsbury? We have answers.

What is the difference between open-cell and closed-cell spray foam?

Closed-cell foam is denser, provides a higher R-value per inch (R-6.5 vs R-3.7), and acts as a vapor and moisture barrier. Open-cell foam is lighter, more flexible, and more affordable. For roofing applications in St. Johnsbury we typically recommend closed-cell for its waterproofing properties. For interior wall insulation, either type may be appropriate.

How much does spray foam insulation cost in St. Johnsbury?

Spray foam insulation costs in St. Johnsbury 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 St. Johnsbury homeowners see a full return on investment through energy savings within 3 to 5 years.

Is spray foam roofing energy efficient in St. Johnsbury, VT?

Yes. Spray foam roofing provides the highest R-value per inch of any commercial roofing insulation — typically R-6.5 per inch. In St. Johnsbury, 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.

Do you offer free roof inspections in St. Johnsbury, VT?

Yes. Every project in St. Johnsbury 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.

What type of roof coating lasts the longest in St. Johnsbury?

Silicone roof coatings offer the longest service life for flat and low-slope roofs in St. Johnsbury. 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 St. Johnsbury roof with drainage challenges or heavy weather exposure.

Is spray foam roofing good for flat roofs in St. Johnsbury?

Spray foam is one of the best solutions for flat and low-slope roofs in St. Johnsbury. 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.

What Our Customers Say

"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."

— Betty Jacobson
★★★★☆

"Got a comprehensive inspection done on our warehouse roof. They found three areas of trapped moisture that were invisible from the surface. The early detection saved us from much more expensive structural repairs down the road."

— Dennis Enriquez
★★★★★

"We converted our old built-up roof to spray foam and could not be happier. The insulation value alone has cut our HVAC costs significantly. The crew explained every step and left the site spotless."
