On most jobs, codes change, and the San Francisco Department of Building Inspection applies the version current on the day the permit issues, which is one reason a Outer Mission quote should state the assembly being installed. Permit requirements in Outer Mission run through the San Francisco Department of Building Inspection. Minor repairs usually do not require one; a tear-off and replacement does.

That is as true in Outer Mission as anywhere in San Francisco County. A permitted Outer Mission re-roof leaves a record that supports any later insurance claim on the same roof.

Check that the Outer Mission crew doing the work is employed by the company quoting it.
2Outer Mission Roofing and the Local Climate
Dry offshore winds reach Outer Mission through autumn, lifting shingle tabs and ridge caps in the direction roofs are least lapped to resist. That is as true in Outer Mission as anywhere in San Francisco County. On most jobs, thermal cycling does the deterioration in Outer Mission — hot afternoons, cool nights, and materials expanding and contracting against their fixings all year. Worth knowing before you sign anything. Dust and grit settle on Outer Mission roofs through the dry months and wash into the drainage the first time it rains. Put simply, attic ventilation on a Outer Mission property is not optional — trapped heat cooks the covering from underneath. Tile underlayment in Outer Mission dries out and goes brittle while the tile above it still looks new from the street. Worth knowing before you sign anything. Outer Mission gets its rain in a handful of concentrated winter storms, which means drainage that sat dry collecting debris has to move everything at once.
Skylight seals on Outer Mission roofs want checking annually, as they fail quietly and drip into the ceiling cavity. In practice, the majority of Outer Mission roofs that fail early fail at a penetration someone could have resealed for a few hundred dollars. A maintenance record on a Outer Mission roof covering also helps at claim time, given that it shows the failure was sudden rather than neglected. This holds across San Francisco County.
3The Outer Mission Inspection, Step by Step
Moisture readings matter on Outer Mission low-slope roofs. Coating over wet insulation seals the problem in rather than solving it. We check the deck from inside the attic on every Outer Mission project. Daylight through the sheathing tells you more than anything visible from the driveway. Put simply, photographs with dates are part of every Outer Mission inspection, given that an undocumented claim gets read as wear and tear by any adjuster. In practice, a proper Outer Mission inspection starts at the flashings, not the field. Chimneys, vents, skylights and the swamp cooler curb fail long before the covering does. Drone access on steep or fragile Outer Mission roofs gets the detail without anyone walking a covering that cannot take it. San Francisco County is no different. On most jobs, flashing at the wall junction is checked earliest on any Outer Mission inspection, since that is where the majority of ceiling stains originate.
Check the CSLB licence number in advance of any Outer Mission roofing company starts, and confirm liability cover and workers' compensation are current. This holds across San Francisco County.

That is as true in Outer Mission as anywhere in San Francisco County. Lightweight tile gives Outer Mission homeowners the look without the structural upgrade older framing would otherwise call for. TPO and modified bitumen both work on Outer Mission low-slope roofs, and the choice as a rule comes down to detailing rather than the sheet. San Francisco County is no different. On most jobs, reclaimed tile can be matched on Outer Mission heritage roofs, but the underlayment beneath it should always be new. Architectural shingle outperforms three-tab on a Outer Mission roof covering for a modest extra cost and a meaningfully longer life. Mixing materials across a Outer Mission roof is fine provided each section gets the system it needs and the transitions are flashed properly.
Low-slope sections in Outer Mission hold thermal load worst, which is why coatings and reflective membranes pay for themselves here. Outer Mission gets its rain in a handful of concentrated winter storms, which means drainage that sat dry collecting debris has to move everything at once.
