Roof Systems That Protect Your Property
Dependable Systems and Premium Materials
Commercial buildings in San Rafael require roofing systems that balance strength, energy efficiency, and resilience. That is why we install TPO and single-ply membranes designed specifically for flat and low-slope roofs. These systems improve efficiency, reflect heat, and reduce maintenance needs over time. For projects that call for alternatives, we also install asphalt and composition roofing systems that are selected to meet unique property needs. All materials are obtained from trusted suppliers and installed following manufacturer specifications, ensuring consistency, durability, and lasting performance for every commercial property we serve.

Frequently Asked Questions
How does San Rafael’s mixed coastal and inland weather affect roofing performance?
San Rafael sits in a unique transition zone, experiencing both the harsh UV degradation typical of hot inland valleys and the corrosive, moisture-heavy fog of the coast. This dual-threat environment accelerates rust on metal flashing and causes flat roofing membranes to prematurely crack or chalk.
Is an overlay permitted on a commercial roof in San Rafael?
The City of San Rafael allows only one roof overlay on existing built-up, wood shake, or asphalt roofs. Before a permit can be issued for an overlay, a pre-inspection is legally required to verify that the underlying roof structure is sound enough to support the additional weight.
What is the lifespan of a commercial TPO roof in San Rafael?
When expertly installed by a certified professional and properly maintained, a commercial TPO roofing system boasts a highly reliable life expectancy of 20 to 30 years. Routine bi-annual inspections to clear drainage scuppers and check seam integrity are critical to maximizing this lifespan.
What is the 50% rule for fire ratings in California?
According to the California Building Code, if more than 50% of the total roof area is replaced within any one-year period, the new roof must be upgraded to a minimum Class A fire-retardant rating. Capstone Roofing ensures all commercial installations meet the highest fire safety and building code standards.
