Expert roof waterproofing in San Mateo, CA. Licensed spray foam contractors with manufacturer-backed warranties and free inspections.
Ponding water destroys conventional roof waterproofing because standing water attacks seams and coating adhesion. Our SPF-based waterproofing systems in San Mateo are engineered to handle indefinite ponding — the silicone topcoat does not re-emulsify, soften, or deteriorate in standing water.
The buildings and homes of San Mateo, 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 roof waterproofing solutions using closed-cell spray polyurethane foam that outperforms conventional materials in every measurable category.
Our San Mateo 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 San Mateo property owners rely on to deliver it right.
From inspection to completion, here is how we deliver professional roof waterproofing 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.
"Our 18-year-old roof was showing its age but still structurally sound. Lapolla Industries recommended restoration over replacement and it was the right call. New coating, sealed seams, and a 15-year warranty. Smart investment."
"Lapolla Industries installed a spray foam roof on our warehouse last spring. Their crew was thorough, professional, and finished ahead of schedule. The building stays cooler in summer and the roof looks pristine a year later."
"Our commercial building needed a roof solution that would not require tenant relocation. The restoration approach was perfect — no tear-off noise or debris, minimal odor, and a fully warranted system installed in under two weeks."
