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.
Large-scale commercial roof restoration using SPF and coating systems that extend roof life by 20 or more years without the cost and disruption of full replacement. Phased scheduling available to keep your business operational.
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.
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.
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.
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.
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.
Stop metal roof leaks without replacement. Our elastomeric coating system treats rust, seals every fastener and seam, and creates a continuous waterproof membrane over your entire metal roof — backed by a manufacturer warranty.
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.
Pre-purchase, post-storm, or routine maintenance — our inspection reports give you the data you need to make informed decisions about your roof. Infrared moisture scans reveal trapped water invisible from the surface.
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.
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.
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.
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.
Transform your building with a spray foam roof that insulates, waterproofs, and strengthens in a single application. No tear-off required over most existing substrates. Backed by manufacturer warranties and our own workmanship guarantee.
Alum Rock, 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 Alum Rock, where conventional membrane roofs develop seam failures and ponding issues within years of installation.
For Alum Rock 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 Alum Rock investment for decades.
Here is what sets Lapolla Industries apart from other contractors in Alum Rock.
Every project comes backed by manufacturer material warranties plus our own workmanship guarantee. We handle all warranty registration so you are always covered.
SPF roofing and coating can be applied over existing roof systems without tear-off — no demolition noise, no debris, and no business interruption during installation.
SPF roofing delivers the highest R-value per inch of any commercial insulation. Our customers typically see 20 to 40 percent reductions in heating and cooling costs after installation.
Unlike conventional roofing with seams, joints, and fasteners, spray foam creates a monolithic membrane with zero penetration points — eliminating the most common sources of roof leaks.
No hidden fees, no surprise charges. You receive a detailed written estimate before we start and the final invoice matches — guaranteed. Every line item explained.
Have questions about spray foam in Alum Rock? We have answers.
Silicone roof coatings offer the longest service life for flat and low-slope roofs in Alum Rock. 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 Alum Rock roof with drainage challenges or heavy weather exposure.
If your commercial roof in Alum Rock 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.
Spray foam insulation costs in Alum Rock 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 Alum Rock homeowners see a full return on investment through energy savings within 3 to 5 years.
Absolutely. SPF roofing performs exceptionally in both extremes because the closed-cell foam provides continuous insulation without thermal bridging. In hot Alum Rock summers, the reflective coating reduces surface temperatures by up to 50 degrees. In winter, the insulation value keeps conditioned air inside.
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 Alum Rock 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 Alum Rock we typically recommend closed-cell for its waterproofing properties. For interior wall insulation, either type may be appropriate.
Real reviews from property owners we have served across the country.
"Our old three-layer built-up roof was beyond saving. They stripped everything down to the deck, repaired the substrate, and installed a new spray foam roofing system. The building is better insulated now than it has ever been."
"We needed our concrete roof deck waterproofed before installing new equipment on it. The crew applied a monolithic membrane that handles foot traffic and ponding water. Two years in and zero issues. Money well spent."
"Lapolla Industries waterproofed our commercial building after we had recurring moisture issues. They applied a spray foam base with a silicone topcoat and the building has been completely dry since. Outstanding results."
