Concrete tile suits Nob Hill buildings designed for the weight; laying it on framing that was not is a structural question soonest. We see it on Nob Hill roofs every week. Architectural shingle outperforms three-tab on a Nob Hill roof covering for a modest extra cost and a meaningfully longer service life. San Francisco County is no different.
In practice, many Nob Hill properties carry a covering chosen for price rather than climate, and it shows in how early it fails. Realistically, additions and conversions are common in Nob Hill, and the joint between the original roof and the newer section is where the majority of leaks begin. Garage and patio roofs in Nob Hill are frequently lower slope than the house and require an entirely different system. It is the same story on most Nob Hill streets.
