9Roof Age Across San Francisco

Original decking on older San Francisco homes is often skip sheathing, which changes what can be laid over it. San Francisco County is no different. Solar arrays on San Francisco roof coverings complicate replacement, and the panel age rarely matches the roof covering age. In practice, many San Francisco properties carry a covering chosen for price rather than climate, and it shows in how early it lets go. Additions and conversions are common in San Francisco, and the joint between the original roof covering and the newer section is where most leaks begin. Garage and patio roofs in San Francisco are frequently lower slope than the house and need an entirely different system. In practice, roof pitch across San Francisco varies enough that the right material on one street is the wrong one two blocks away.

As a rule, wind and storm deterioration on a San Francisco roof is covered where it is documented; wear is not covered anywhere. Code upgrade cover decides whether a San Francisco claim pays for bringing the assembly current or only for like-for-like. Policies covering San Francisco properties generally pay for sudden damage and not for age, so the report has to separate the two clearly.
