Annual inspection on a Mission District property typically adds two to three years to the back end of a roof's service life. It is the same story on most Mission District streets.

3How We Inspect a Mission District Roof

As a rule, a Mission District inspection should end with a documented report and photographs, not a verbal summary and a price. In practice, core samples settle the argument on a Mission District low-slope roof when moisture is suspected but not visible. It is the same story on most Mission District streets. Drone access on steep or fragile Mission District roofs gets the detail without anyone walking a covering that cannot take it. This holds across San Francisco County.

Phasing a large Mission District building across two seasons is frequently cheaper than financing the whole work at once. That is as true in Mission District as anywhere in San Francisco County.

9What Sits on Most Mission District Roofs

9The Mission District Inspection, Step by Step

Valley condition is the single best indicator of how a Mission District roof has been maintained. Flashing at the wall junction is checked first on any Mission District inspection, given that that is where most ceiling stains originate. We photograph every elevation on a Mission District job so the documented estimate can be read against what is actually up there. This holds across San Francisco County. We check the deck from inside the attic on every Mission District project. Daylight through the sheathing tells you more than anything visible from the driveway. As a rule, granule loss in the gutters is the earliest honest signal on a Mission District shingle roof covering, and it shows up years before a ceiling stain does.

As a rule, two warranties apply on Mission District the project: the manufacturer's on the material and the installer's on the workmanship. Ask for both. We see it on Mission District roofs every week. Ask any Mission District roofer what happens if the deck is worse than expected, and get the answer before the covering comes off. On most jobs, written scope, written price and a documented warranty are the minimum on any Mission District work. This holds across San Francisco County.
