Commercial Roofing for San Francisco Businesses and Property Managers
Nearly every commercial and mixed-use building in this city runs a flat or low-slope roof system — we install and maintain them with proper drainage and Title 24 compliance, and plan work around your tenants and business hours.
What Commercial Roofing Involves in San Francisco
Most commercial and light-industrial buildings here run low-slope or flat systems, which need a different maintenance approach than a residential shingle roof, plus a few city-specific realities:
- Drainage design — ponding water is the single biggest driver of commercial flat-roof failure, addressed at install through proper slope and drain placement.
- Title 24 cool-roof compliance — required statewide for flat/low-slope commercial re-roofing.
- Rooftop equipment coordination — HVAC units and vents common on commercial flat roofs need flashing and detailing done around them, not through them.
- Minimal-disruption scheduling — timed around your business, tenants, and the realities of staging on a dense city block.
What a Commercial Job Includes
- Roof assessment covering membrane condition, drainage, and flashing.
- Written, itemized estimate with a realistic timeline for your property.
- Work scheduled to minimize disruption to tenants and customers.
- Post-completion walkthrough and documentation for your records.

What types of commercial roofs do you work on?
Mostly low-slope and flat systems — TPO, modified bitumen, and similar membrane roofing — on retail storefronts, mixed-use buildings, and small offices around San Francisco. Nearly all of the city's commercial and mixed-use building stock runs flat or low-slope roofing.
Do commercial roofs need to meet Title 24 cool-roof requirements?
Yes — California's Title 24 requires cool-roof-rated materials for flat and low-slope commercial re-roofing statewide, San Francisco included. We factor this into every commercial estimate.
Can you schedule work around business hours?
Yes. We plan commercial jobs to minimize disruption to tenants, customers, and street-level businesses, including timing louder work outside peak hours where possible.
Do you offer maintenance programs for commercial and mixed-use buildings?
We can set up periodic inspections for flat commercial roofs, which is the single best way to catch a failing membrane or drainage issue before it becomes an interior leak.
