Question

Can someone please explain to me which roof type is the best in seismo. zones. I live in San Diego CA that hasnít being hit by strong earthquakes for quite sometime, but who know what tomorrow bringsÖ.
Is the tile roof of composite tending to handle earthquakes better?

thanks

Depends on the trusses under the roof and what they are designed to support. If you currently have a comp. roof, you can't put a clay or concrete tile roof on it. The trusses simply won't support the weight. One roof you didn't mention that you might look into is metal. Very lightweight, very strong, very long lasting, and there are some very attractive ones out there.

Since you have a shake roof, a tile or slate roof is out of the question, unless you want to install new trusses first. Going to a comp. roof will require that you put down sheathing (OSB or plywood). That can be installed right over the skip sheathing you already have. A metal roof would be somewhat noisier in a rainstorm, but blowing 6" of cellulose (NOT fiberglass!) into the attic would cure that (and help with your heating and cooling costs to boot!)
