Expert metal roof coating in El Cajon, CA. Licensed spray foam contractors with manufacturer-backed warranties and free inspections.
Our metal roof coating process in El Cajon starts with surface preparation — rust treatment, fastener tightening, and seam repair — then applies a bridging fabric at critical joints followed by a full elastomeric topcoat. The result is a sealed, reflective roof that looks and performs like new.
When El Cajon, CA property owners need metal roof coating, they turn to Lapolla Industries for the same reason thousands of customers nationwide do: we solve the root problem, not just the symptom. Our diagnostic approach uses infrared scanning, moisture mapping, and visual inspection to ensure the solution we recommend is the one your building actually needs.
With over two decades of spray foam experience, our El Cajon crews have seen every metal roof coating scenario California weather can create. We use that experience to select the right foam type, coating system, and application method for your specific property — delivering metal roof coating results that hold up to El Cajon conditions year after year.
From inspection to completion, here is how we deliver professional metal roof coating results.
Every project begins with a thorough inspection of your property. We evaluate the existing condition, identify problem areas, and use infrared moisture scanning when needed to reveal hidden issues. You receive a detailed report with photos and honest recommendations.
Our preparation process includes substrate inspection, cleaning, moisture testing, and priming. We mask all areas not receiving foam, set up containment where needed, and verify that temperature and humidity conditions are within specification for application.
Using precision spray equipment, our crews apply the foam in controlled passes to achieve the specified thickness and density. The closed-cell foam expands 30 to 40 times its liquid volume, conforming to every detail of the surface and creating a seamless monolithic barrier.
After the foam cures, we apply a UV-protective coating — silicone, acrylic, or elastomeric — selected for your specific application and climate. We then remove all masking, clean up the work area, and conduct a final walkthrough with you to verify satisfaction.

"Had silicone roof coating applied to our office building. The crew was professional and the finish is smooth and uniform. Energy savings have been noticeable on our monthly bills. Would recommend for any flat or low-slope roof."
"We manage a 40,000 square foot retail center and the roof was near end of life. Instead of tearing it off they restored it with a spray foam and coating system. Saved us over sixty percent versus replacement and added twenty years of life."
"Our flat roof on a strip mall had been leaking for months. Two other companies just slapped tar on it. These guys actually found the real problem — failed flashing at a parapet wall — and fixed it permanently."
