A done right Portola inspection starts at the flashings, not the field. Chimneys, vents, skylights and the swamp cooler curb give out long before the covering does. This holds across San Francisco County. Core samples settle the argument on a Portola low-slope roof when moisture is suspected but not visible. Deck fastener pull-through is checked on older Portola roofs, since the sheathing often fails ahead of the shingle does. San Francisco County is no different. Realistically, we inspect the deck from inside the attic on every Portola work. Daylight through the sheathing tells you more than anything visible from the driveway.
The permit record for a Portola property is public, which is how a buyer's inspector checks the roof was done properly. In practice, historic districts near Portola may restrict covering type and colour, which is worth confirming in advance of materials are ordered. This holds across San Francisco County. Permit requirements in Portola run through the San Francisco Department of Building Inspection. Minor repairs usually do not need one; a tear-off and replacement does. San Francisco County is no different.
