Lemon Hill's trusted spray foam contractor for commercial roofing, residential insulation, and emergency roof repair across California.
From SPF roof installation to attic insulation, Lapolla Industries covers every spray foam need in Lemon Hill.
When your roof is structurally sound but the surface is deteriorating, restoration is the smart investment. We clean, repair, and recoat your entire roof with a warranted system that performs like new at a fraction of replacement cost.
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.
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.
Active roof leak? We locate the source using advanced detection methods, then repair it permanently at the root cause. No guesswork, no temporary patches — just lasting results backed by our workmanship warranty.
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.
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.
Transform your crawl space from a moisture liability into a conditioned, energy-efficient part of your building envelope. Spray foam eliminates condensation, prevents mold conditions, and dramatically improves floor comfort above.
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.
Our replacement process is thorough: remove existing roofing to the deck, inspect and repair substrate, apply closed-cell SPF to specified thickness, and finish with a UV-protective coating. The result is a monolithic roof system with no seams to fail.
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.
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.
Upgrade your attic insulation from fiberglass or cellulose to spray foam and feel the difference the same day. SPF does not settle, sag, or leave gaps — it expands to fill every cavity and seals air leaks that other materials miss.
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.
Our maintenance programs extend roof life and reduce total cost of ownership. Semi-annual or annual visits include drain clearing, seam inspection, penetration checks, coating condition assessment, and immediate repair of minor issues.
Extend the life of your existing roof by 15 to 20 years with a silicone coating that seals every seam, reflects solar heat, and handles ponding water without softening or deteriorating. Professional application with manufacturer warranty.
Lemon Hill, CA 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 Lemon Hill, where conventional membrane roofs develop seam failures and ponding issues within years of installation.
For Lemon Hill 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 Lemon Hill investment for decades.

Have questions about spray foam in Lemon Hill? We have answers.
Silicone roof coatings offer the longest service life for flat and low-slope roofs in Lemon Hill. 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 Lemon Hill roof with drainage challenges or heavy weather exposure.
Absolutely. SPF roofing performs exceptionally in both extremes because the closed-cell foam provides continuous insulation without thermal bridging. In hot Lemon Hill 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 Lemon Hill. 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.
If your commercial roof in Lemon Hill 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.
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 Lemon Hill homes with persistent crawl space moisture issues, closed-cell foam combined with vapor barrier encapsulation provides a permanent solution.
Spray foam insulation costs in Lemon Hill 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 Lemon Hill homeowners see a full return on investment through energy savings within 3 to 5 years.
Real reviews from property owners we have served across the country.
"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."
"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."
"They waterproofed our entire flat roof with a seamless elastomeric membrane. Two years later and not a single drop of water has gotten through. The application was clean and fast — three days for 8,000 square feet."
