California's trusted spray foam contractor for commercial roofing, residential insulation, and emergency roof repair across Maryland.
From SPF roof installation to attic insulation, Lapolla Industries covers every spray foam need in California.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
California, MD experiences the kind of temperature swings that punish conventional roofing and insulation. Lapolla Industries installs spray polyurethane foam systems engineered to perform in exactly these conditions — continuous insulation with no thermal bridging, no seams, and no weak points where Maryland weather can exploit gaps in your building envelope.
For California businesses watching their utility bills climb, a spray foam roof restoration can reduce cooling costs by 20 to 40 percent while extending roof life by 20 or more years. For homeowners, attic and crawl space insulation with closed-cell SPF eliminates hot spots, cold drafts, and the energy waste that comes with them. Call (866) 605-0362 for a free energy assessment.
Quality, integrity, and results — the Lapolla Industries difference for California property owners.
Lapolla Industries has been at the forefront of spray polyurethane foam technology since 2003 — with deep roots in SPF manufacturing and application that few competitors can match.
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.
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.
Our crews live and work in the communities we serve. We understand local building codes, climate conditions, and the best SPF systems for your specific region.
Storms do not wait and neither do we. Our emergency crews are on call around the clock to tarp, secure, and protect your property when you need it most.
Common questions about spray foam roofing and insulation in California, MD.
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 California we typically recommend closed-cell for its waterproofing properties. For interior wall insulation, either type may be appropriate.
Spray foam insulation costs in California 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 California 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 California 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 California 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 California. 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.
Silicone roof coatings offer the longest service life for flat and low-slope roofs in California. 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 California roof with drainage challenges or heavy weather exposure.
Real reviews from property owners we have served across the country.
"Lapolla Industries insulated our crawl space with spray foam and encapsulated the entire area. No more cold floors in winter, no more musty smell. The crew worked in tight quarters and did an excellent job. Very impressed."
"Attic insulation upgrade from blown-in to spray foam. The crew masked everything off properly and the overspray was minimal. The temperature in our attic dropped dramatically and so did our energy bills. Worth the investment."
"Lapolla Industries does our annual roof inspections across four properties. Every report includes current condition ratings, remaining life estimates, and prioritized repair recommendations. Data-driven and extremely useful for budgeting."
