Clearing the Potrero Hill gutters in late autumn prevents most of the damage the first storm would otherwise cause. It is the same story on most Potrero Hill streets.

2What a Potrero Hill Inspection Covers

Infrared scanning on a Potrero Hill commercial roof locates wet insulation that no visual inspection would find. We photograph every elevation on a Potrero Hill job so the written estimate can be read against what is actually up there. Flashing at the wall junction is checked first on any Potrero Hill inspection, because that is where nearly all ceiling stains originate. Water readings matter on Potrero Hill low-slope roofs. Coating over wet insulation seals the trouble in rather than solving it. Worth knowing before you sign anything. We check the deck from inside the attic on every Potrero Hill project.

Realistically, original decking on older Potrero Hill homes is often skip sheathing, which changes what can be laid over it.

As a rule, 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. A Potrero Hill roof covering is inspected from the attic as well as the roof surface; half the evidence is underneath.

4Potrero Hill Permit Requirements

Full replacements in Potrero Hill generally require a permit through the San Francisco Department of Building Inspection, with an inspection once the work is finished. This holds across San Francisco County. Inspection scheduling in Potrero Hill adds a day or two to the programme and should be in the contractor's timeline from the start. Unpermitted roofing in Potrero Hill surfaces at resale. the San Francisco Department of Building Inspection keeps the record, and a buyer's inspector knows to look for it.

A permitted Potrero Hill re-roof leaves a record that supports any later insurance claim on the same roof.

In practice, cost on a Potrero Hill roof comes down to size, pitch, how many layers come off, and what the deck looks like underneath. Budgeting a Potrero Hill replacement a few seasons out costs nothing and removes the pressure of choosing a contractor during a storm. In practice, a Potrero Hill written price that comes in far below the others is in most cases missing the flashing, the permit or the disposal.

Concrete tile suits Potrero Hill buildings designed for the weight; laying it on framing that was not is a structural question earliest. Put simply, lightweight tile gives Potrero Hill homeowners the look without the structural upgrade older framing would otherwise need.

Tile is widespread across Potrero Hill, and the tile will outlive the underlayment beneath it by decades — which is what catches owners out.
