San Francisco's housing stock creates roofing challenges that outside contractors often underestimate. Victorian homes in Alamo Square, Pacific Heights, and Haight-Ashbury, along with Edwardian homes in Nob Hill and the Mission, frequently combine steeply pitched rooflines with flat or low-slope rear sections, each requiring a different installation approach. Anderson Roofing & Sheet Metal Co. Inc has worked on all of these roof types across the city for nearly a century.
What Roofing Materials Are Best for San Francisco Homes?
The right material depends on your home's architecture, slope, and neighborhood microclimate. Daily thermal variation, coastal salt air, and sustained winds all affect long-term roof performance. Anderson Roofing & Sheet Metal Co. Inc installs the following systems for San Francisco residential properties:
- Tile and Slate: Specialty materials that can last a lifetime. Slate tiles are secured with copper nails and sourced from Vermont, with a lifespan of up to 100 years.
- Wood Shingles and Shakes: Wood shingles are applied over spaced sheathing for ventilation; wood shakes are machine-sawed cedar with a uniform butt thickness and smooth surface.
- Built-Up Roofing (Tar, Gravel, and Modified Bitumen): Four- and five-ply built-up roofs, including modified bitumen, with a life expectancy of 20 to 25 years. This system suits the flat and low-slope sections common on Victorian and Edwardian flats throughout the Mission and Noe Valley.
- Custom Sheet Metal Roofing: Fabricated and installed to handle San Francisco's coastal salt air and wind exposure.
San Francisco Residential Roofing: The Installation Process
Every residential roofing installation follows a clear sequence:
- Free Consultation and Roof Assessment: The team evaluates the existing roof condition, identifies structural or drainage issues, and recommends appropriate materials.
- DBI Permit Application: San Francisco Building Code requires a permit from the Department of Building Inspection for reroofing work that involves installing, repairing, or removing roof sheathing, which covers most full replacements. Your contractor handles permit coordination.
- Tear-Off and Deck Preparation: Old material is removed and the deck is inspected. Damaged sheathing is repaired or replaced before new material goes down.
- Installation and Flashing: New roofing is installed per the approved permit scope, with proper flashing, ventilation, and Title 24 documentation.
- DBI Final Inspection: Anderson Roofing & Sheet Metal Co. Inc schedules and manages the required final inspection to close the permit.
Victorian and Edwardian Roof Considerations
Older San Francisco homes demand careful attention. Victorian and Edwardian flats in the Mission, many built after the 1906 earthquake, feature mixed flat and low-slope systems on wood-frame structures. Party walls create complex drainage and flashing challenges, and seismic activity stresses older brick chimney flashing. North winds funneled through the Golden Gate can reach 25 to 40 mph during winter storms, lifting unsecured shingles and forcing water under low-slope roofing edges. Scheduling a residential roofing installation before winter is often the most practical way to protect these structures.

Frequently Asked Question
Does a Residential Roof Replacement in San Francisco Require a Permit?
In almost all cases, yes. Under San Francisco Building Code Section 106a.2, a permit is required before installing, repairing, or removing roof sheathing on residential and commercial properties. A narrow exemption applies to reroofing that covers 25 percent or less of the roof surface in any 12-month period and does not involve the sheathing, so minor repairs may not need one. A licensed C-39 contractor pulls the permit on your behalf.
How Long Does a Residential Roofing Installation Take?
Most installations are completed within a few days to a week, depending on project size, material type, and weather. Victorian and Edwardian homes with complex roof sections may take longer. A realistic timeline is provided during your free consultation.
What Materials Work Best on Flat-Roof Victorians and Edwardians?
Flat and low-slope sections typically call for built-up systems or modified bitumen. Pitched sections may use asphalt shingles or other appropriate materials. The right choice depends on slope, drainage, and access conditions.
How Do I Know If My Home Needs a Full Installation or Just a Repair?
A free inspection can determine whether repairs are sufficient or whether a full installation is the better investment. Widespread material failure, significant water intrusion, or a roof nearing the end of its rated lifespan generally point toward full replacement.
Is Anderson Roofing & Sheet Metal Co. Inc Licensed and Insured?
Yes. Anderson Roofing & Sheet Metal Co. Inc is family-owned and union-certified, serving the SF Bay Area since 1928. Most roofing services are backed by a guarantee; contact the team for details.
