What Every San Francisco Homeowner Should Know About Roofing
Primary Local Risk
Persistent marine fog keeps roofs damp — moss growth, wood rot, and flashing corrosion are endemic
Material Recommendation
Metal roofing or premium architectural shingles with copper or stainless flashings; zinc strips for moss control
San Francisco reroofing works under stricter rules than most California cities. The Department of Building Inspection requires a permit under Building Code Section 106A.2 for any full tear-off, any work that touches roof sheathing, or partial reroofing that covers more than 25% of the roof surface within a 12-month period — permit fees run $256.62 for single-family homes and duplexes, $386.22 for other building types. Every roofing material installed in the city must carry a Class A fire rating; untreated cedar shake, common in older Bay Area homes, isn't permitted for reroofing. If a contractor proposes a torch-applied flat roof — common on SF's many flat and low-slope roofs — the job also needs a separate SF Fire Department Operational Permit and a dedicated fire watch person on site during the work and for an hour after.
Homes in designated historic districts — Alamo Square, the Western Addition, and Pacific Heights are the ones most often affected — go through an additional layer of review: the Planning Department's Historic Preservation staff signs off on material and color choices before a reroof can proceed. Every reroof also has to meet California's Title 24 cool-roof standard, which sets minimum solar reflectance and thermal emittance for the city's climate zone.

How Storm Damage Roof Repair Works in San Francisco
Free Storm Damage Inspection
A roofer inspects the full roof — shingles, metal components, flashings, gutters — and documents all storm damage with photos and measurements. Storm damage from persistent fog moisture, seismic movement, and coastal wind is often invisible from the ground but significant on close inspection.
Insurance Claim Documentation
The contractor prepares a detailed damage report formatted for CA insurance adjusters — itemized costs, measured scope, dated photos. Many contractors will attend the adjuster visit to ensure the full scope is included in your claim.
Emergency Stabilization
If your San Francisco home has open damage from persistent fog moisture, seismic movement, and coastal wind, heavy-duty tarps or temporary sealant are applied immediately to prevent further water intrusion while the permanent repair is processed through insurance.
Approved Repairs
After insurance approval, the crew completes the permanent repair: matching shingles, resealed flashings, restored gutters. If persistent fog moisture, seismic movement, and coastal wind caused widespread damage, a partial or full re-roof may be approved and completed by your San Francisco contractor.
Final Inspection & Warranty
A water test confirms the repair is watertight. You receive before-and-after documentation, a workmanship warranty, and final invoice records suitable for your insurance reimbursement.
