Lightweight tile gives Nob Hill owners the look without the structural upgrade older framing would otherwise call for. That is as true in Nob Hill as anywhere in San Francisco County.

A Nob Hill roof with working drainage outlasts an identical roof covering without it by seasons.

Deck replacement on a Nob Hill job is unknown until the tear-off, which is why it belongs in the contract as a per-sheet rate. Cheap Nob Hill quotes usually skip the flashing. That is where the money is saved and where the next leak arrives. Budgeting a Nob Hill replacement a few years out costs nothing and removes the pressure of choosing a contractor during a storm. It is the same story on most Nob Hill streets.

5Nob Hill Roofing and Your Policy

A Nob Hill quote that comes in far below the others is generally missing the flashing, the permit or the disposal.

9Which System Fits a Nob Hill Property

Flat and low-slope sections in Nob Hill need a membrane or a coating system, not shingle laid at a pitch it was never designed for. Concrete tile suits Nob Hill buildings designed for the weight; laying it on framing that was not is a structural question first. That is as true in Nob Hill as anywhere in San Francisco County. On most jobs, architectural shingle outperforms three-tab on a Nob Hill roof covering for a modest extra cost and a meaningfully longer service life. That is as true in Nob Hill as anywhere in San Francisco County. Mixing materials across a Nob Hill roof is fine provided each section gets the system it requires and the transitions are flashed properly. That is as true in Nob Hill as anywhere in San Francisco County. Realistically, coatings suit Nob Hill buildings with a in good order deck and a tired surface — they buy years, but they do not fix water already trapped in the insulation. Underlayment choice matters more than covering choice on a Nob Hill tile roof, because that is the layer doing the waterproofing.

Ask a Nob Hill contractor for recent addresses nearby and go and look at the work from the street. Realistically, a good Nob Hill roofer will talk you out of work you do not need, which is the clearest signal there is. A Nob Hill roofing company who will not put the assembly in writing is not quoting the same work as the one who will.
