Expert silicone roof coating in Castro Valley, CA. Licensed spray foam contractors with manufacturer-backed warranties and free inspections.
Lapolla Industries applies high-solids silicone coatings over existing metal, TPO, EPDM, and SPF roofs in Castro Valley. A single application seals every seam, reflects up to 85 percent of solar radiation, and adds 15 to 20 years of warranted waterproof protection to your existing roof.
The buildings and homes of Castro Valley, CA face unique challenges — from seasonal temperature extremes to storm exposure — that demand roofing and insulation systems built for performance, not just price. Lapolla Industries delivers silicone roof coating solutions using closed-cell spray polyurethane foam that outperforms conventional materials in every measurable category.
Our Castro Valley customers see the difference in their energy bills, their comfort levels, and the longevity of their roofing systems. Spray foam does not degrade like fiberglass, does not develop seam failures like TPO, and does not crack like built-up roofing. It is a permanent solution — and Lapolla Industries is the permanent partner Castro Valley property owners rely on to deliver it right.
From inspection to completion, here is how we deliver professional silicone roof coating results.
Before any work begins, our certified inspectors evaluate your property and provide a comprehensive assessment including current condition, repair needs, and recommended SPF solutions. You get a written estimate with no hidden fees.
Proper surface preparation is critical for spray foam adhesion and long-term performance. Our crews clean, dry, and prime all surfaces, remove debris and loose material, and ensure the substrate meets manufacturer specifications before any foam is applied.
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.
We finish every project with the appropriate protective coating, thorough cleanup, and a detailed walkthrough. You receive project documentation including photos, material specifications, warranty registration, and maintenance recommendations.

Our reputation is built on results. Here is what our customers have to say.
"Had spray foam applied to our flat commercial roof and the difference is night and day. No more ponding water, energy bills dropped noticeably, and the seamless membrane means zero leak points. Should have done this years ago."
"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."
"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."
