Winona's trusted spray foam contractor for commercial roofing, residential insulation, and emergency roof repair across Minnesota.
From SPF roof installation to attic insulation, Lapolla Industries covers every spray foam need in Winona.
Our commercial restoration process preserves your existing roof structure, adds insulation value, and applies a warranted waterproof coating system — saving 50 to 70 percent versus tear-off and replacement on buildings of any size.
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.
Elastomeric coatings for standing seam, corrugated, and R-panel metal roofs. We seal rust spots, failing fasteners, open seams, and ridge caps — stopping leaks and adding reflective energy savings in a single application.
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.
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 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.
Ponding water, chronic leaks, and moisture infiltration destroy roofs and building interiors. Our waterproofing systems use closed-cell spray foam and silicone coatings to create an impermeable barrier that handles standing water indefinitely.
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.
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.
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.
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.
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.
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.
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 Winona, MN.
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 Winona homes with persistent crawl space moisture issues, closed-cell foam combined with vapor barrier encapsulation provides a permanent solution.
Absolutely. SPF roofing performs exceptionally in both extremes because the closed-cell foam provides continuous insulation without thermal bridging. In hot Winona summers, the reflective coating reduces surface temperatures by up to 50 degrees. In winter, the insulation value keeps conditioned air inside.
Spray foam is one of the best solutions for flat and low-slope roofs in Winona. 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.
A properly installed SPF roof in Winona 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 Winona crew is fully licensed, bonded, and insured for spray foam roofing and insulation work. We carry general liability and workers compensation coverage on every project. You can request proof of insurance before any work begins.
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 Winona crews evaluate the existing substrate to ensure it is structurally sound before application.
