RE: Spanish Tile Roof

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Anywhere from 9 psf up, if you cant get the mfr's installed weight you should ask the architect, it depends on how high they stack and if they are using mud to set them in.  See if there is a spec sheet on them, that may be the easiest.
 
Typically there is a layer of 30# felt w/ flashing at the valleys etc, if they are on furring, the plywood still supports it, so you may end up w/ 5/8".   If the slope is less than 3/12, they typically use a waterproof membrane.

Subject: Spanish Tile Roof

I need some help from a southwest engineer.  I’m designing a roof with Spanish tiles.  It’s the kind that looks like half of a terra cotta pipe running up and down the slope, alternating direction.   What is the typical design dead uniform loading for these?  What goes under these, a waterproof membrane?  Are they typically supported on plywood or wood battens?

 

Thanks.
