Flat and low-slope sections in Outer Mission need a membrane or a coating system, not shingle laid at a pitch it was never designed for. We see it on Outer Mission roofs every week.

9Storm Damage Claims in Outer Mission

We do not advise filing a Outer Mission claim where the damage is clearly age, because a declined claim stays on the record. Insurance work in Outer Mission turns on documentation. Damage recorded before anything is touched is the difference between a paid claim and a denied one. San Francisco County is no different. Wind load and storm damage on a Outer Mission roof is covered where it is documented; wear is not covered anywhere. This holds across San Francisco County. Put simply, photographs taken before any tarping on a Outer Mission property are the most valuable evidence in the whole claim. Partial claims on a Outer Mission roof are common and should be priced as repairs rather than inflated into replacements. This holds across San Francisco County. Actual cash value and replacement cost behave very differently on an older Outer Mission roof, and the policy wording decides which applies.

Photographs with dates are part of every Outer Mission inspection, given that an undocumented claim gets read as wear and tear by any adjuster. It is the same story on most Outer Mission streets. On most jobs, infrared scanning on a Outer Mission commercial roof locates wet insulation that no visual inspection would find. That is as true in Outer Mission as anywhere in San Francisco County. Lifting a few tiles in two or three places is the only way to date the underlayment on a Outer Mission tile roof, and it takes fifteen minutes.
