Energy-efficient spray foam solutions for San Jose, CA. Roofing, insulation, and coatings that reduce energy costs and extend roof life by decades.
Comprehensive spray foam roofing and insulation services tailored for San Jose properties.
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.
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.
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.
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.
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.
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.
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.
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.
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 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.
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.
Silicone coatings provide the longest service life of any roof coating product. Our crews apply them over metal, TPO, EPDM, built-up, and spray foam surfaces — sealing the entire roof in a seamless, reflective, waterproof membrane.
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.
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.
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.

Have questions about spray foam in San Jose? We have answers.
A properly installed SPF roof in San Jose 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 roofing provides the highest R-value per inch of any commercial roofing insulation — typically R-6.5 per inch. In San Jose, 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.
Spray foam insulation costs in San Jose 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 San Jose homeowners see a full return on investment through energy savings within 3 to 5 years.
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 San Jose homes with persistent crawl space moisture issues, closed-cell foam combined with vapor barrier encapsulation provides a permanent solution.
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 San Jose we typically recommend closed-cell for its waterproofing properties. For interior wall insulation, either type may be appropriate.
Yes. Every project in San Jose 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.
See what our customers have to say about their experience with Lapolla Industries.
"Had spray foam applied to our flat commercial roof and the difference is night and day. No more ponding water, energy bills dropped noticeably, and the seamless membrane means zero leak points. Should have done this years ago."
"Regular maintenance visits twice a year keep our flat roof in great shape. They clean drains, check seams, inspect all penetrations, and send a detailed report with photos. Good preventive program at a reasonable cost."
"Had our attic insulated with spray foam after years of fiberglass that kept settling and losing its R-value. Lapolla Industries did a clean install — no gaps, no missed spots. Our HVAC system runs half as much now."
