Port St. John's trusted spray foam contractor for commercial roofing, residential insulation, and emergency roof repair across Florida.
From SPF roof installation to attic insulation, Lapolla Industries covers every spray foam need in Port St. John.
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.
Spray foam roofs are built to last, but they do need occasional repair. Our crews fix bird pecks, foot traffic damage, hail impacts, and coating wear — extending the life of your SPF system without a costly full recoat.
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 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.
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.
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.
When severe weather damages your roof, our storm response crews deploy fast — securing your property, documenting every impact point for your insurance claim, and restoring your roof with quality materials and expert workmanship.
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.
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.
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.
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.
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.
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.
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 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.
Port St. John, FL is home to a growing mix of commercial, industrial, and residential properties — and Lapolla Industries serves all of them with professional spray foam roofing and insulation. Our SPF systems are particularly effective for the flat-roofed commercial buildings common in Port St. John, where conventional membrane roofs develop seam failures and ponding issues within years of installation.
For Port St. John facility managers and building owners, spray foam offers something no other roofing system can: a single application that provides waterproofing, insulation, and structural reinforcement simultaneously. No separate vapor barrier. No separate insulation board. No seams to fail. Just one seamless, self-adhering membrane that protects your Port St. John investment for decades.

Have questions about spray foam in Port St. John? We have answers.
Spray foam is one of the best solutions for flat and low-slope roofs in Port St. John. 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.
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 Port St. John we typically recommend closed-cell for its waterproofing properties. For interior wall insulation, either type may be appropriate.
A properly installed SPF roof in Port St. John 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.
If your commercial roof in Port St. John 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.
Silicone roof coatings offer the longest service life for flat and low-slope roofs in Port St. John. 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 Port St. John roof with drainage challenges or heavy weather exposure.
Spray foam insulation costs in Port St. John 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 Port St. John homeowners see a full return on investment through energy savings within 3 to 5 years.

"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 had a persistent leak that three different contractors could not find. Their team used moisture scanning equipment and pinpointed it to a failed pipe boot in minutes. Fixed it the same day. Incredible diagnostic work."
