In practice, attic ventilation on a Potrero Hill property is not optional — trapped heat cooks the covering from underneath.
We inspect the deck from inside the attic on every Potrero Hill job. Daylight through the sheathing tells you more than anything visible from the driveway. It is the same story on most Potrero Hill streets. Drone access on steep or fragile Potrero Hill roofs gets the detail without anyone walking a covering that cannot take it. We look over ventilation on every Potrero Hill project, given that a roof that cannot breathe will not reach its rated life.
9The Potrero Hill Inspection, Step by Step
Lifting a few tiles in two or three places is the only way to date the underlayment on a Potrero Hill tile roof covering, and it takes fifteen minutes. Put simply, drone access on steep or fragile Potrero Hill roofs gets the detail without anyone walking a covering that cannot take it. A done right Potrero Hill inspection starts at the flashings, not the field. Chimneys, vents, skylights and the swamp cooler curb fail long before the covering does. Flashing at the wall junction is checked first on any Potrero Hill inspection, because that is where most ceiling stains originate. This holds across San Francisco County. Realistically, a Potrero Hill roof is inspected from the attic as well as the roof surface; half the evidence is underneath. Valley condition is the single best indicator of how a Potrero Hill roof covering has been maintained. We see it on Potrero Hill roofs every week.
Cool-rated coverings are worth specifying in Potrero Hill even where code does not require them. In practice, metal has grown in Potrero Hill for its lifespan and reflectivity, though the fixing system has to allow for movement or the panels telegraph every fastener. Mixing materials across a Potrero Hill roof is fine provided each section gets the system it calls for and the transitions are flashed properly.
