Spray Foam Services in San Marcos

Full-spectrum spray foam solutions for residential and commercial buildings in San Marcos, CA.

Metal Roof Coating

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.

Roof Waterproofing

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.

Roof Replacement

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.

Spray Foam Roofing

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.

Spray Foam Roofing Repair

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.

Roof Leak Repair

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.

Roof Maintenance

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.

Roof Restoration

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.

Silicone Roof Coating

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.

Commercial Roof Restoration

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.

Attic Insulation

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.

Crawl Space Insulation

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.

Roof Inspection

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.

Flat Roof Repair

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.

Storm Damage Roof Repair

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.

Frequently Asked Questions

Have questions about spray foam in San Marcos? We have answers.

Can spray foam fix a leaking crawl space in San Marcos?

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 Marcos homes with persistent crawl space moisture issues, closed-cell foam combined with vapor barrier encapsulation provides a permanent solution.

How do I know if my commercial roof needs restoration or replacement?

If your commercial roof in San Marcos 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.

How much does spray foam insulation cost in San Marcos?

Spray foam insulation costs in San Marcos 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 Marcos homeowners see a full return on investment through energy savings within 3 to 5 years.

Is spray foam roofing energy efficient in San Marcos, CA?

Yes. Spray foam roofing provides the highest R-value per inch of any commercial roofing insulation — typically R-6.5 per inch. In San Marcos, 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.

What is the difference between open-cell and closed-cell spray foam?

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 Marcos we typically recommend closed-cell for its waterproofing properties. For interior wall insulation, either type may be appropriate.

Is spray foam roofing good for flat roofs in San Marcos?

Spray foam is one of the best solutions for flat and low-slope roofs in San Marcos. 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.

★★★★★

"Our corrugated metal roof was rusting at every fastener and seam. They cleaned the entire surface, treated the rust, and applied a thick elastomeric coating. The roof looks brand new and is completely sealed now."

— Donald Whitaker
★★★★★

"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."

— Karen Delgado
★★★★★

"Water was coming in around our skylight every time it rained. Lapolla Industries traced it to deteriorated sealant and improper flashing. They redid everything and we have been bone dry through two heavy storm seasons now."
