Commercial Roof Repair Process in San Francisco
Commercial Roof Survey
A certified San Francisco commercial roofing contractor surveys the full roof system — membrane surface, seams, penetrations (HVAC curbs, drains, skylights), perimeter flashing, and parapet walls. Commercial surveys in San Francisco include moisture scanning on larger properties to detect water trapped within insulation layers, common damage from persistent fog moisture, seismic movement, and coastal wind.
Scope of Work & Documentation
The contractor provides a written scope of work with itemized costs, material specifications, and timeline. For managed San Francisco properties, documentation is formatted for property management review, insurance adjusters, and building owners. If a claim is involved, the contractor coordinates directly with your CA insurance adjuster.
Commercial-Grade Repair
Repairs use commercial-certified materials matched to your existing roofing system — heat-welded TPO patches, EPDM adhesive, torch-applied modified bitumen, or BUR flood coat. All penetration flashings are inspected and resealed. Work is scheduled to minimize disruption to San Francisco tenants and operations.
Water Testing & Leak Verification
After repair, the contractor performs flood testing or electronic leak detection to verify the full repaired area is watertight. This step is standard for commercial projects in San Francisco and required by most CA property management agreements and commercial insurance documentation.
Warranty & Maintenance Schedule
You receive a written workmanship warranty on all repairs and a biannual inspection schedule for your San Francisco property. Regular maintenance is critical for commercial flat roofs given the demands of persistent fog moisture, seismic movement, and coastal wind on membrane systems in CA.
