hmmmm... tile roof? In the South West?  Perhaps also stucco walls?  thinks 
this transplanted midwesterner as he imagines a Spanish (sorta) style home. 
If so, be aware that stucco is put on over a wire grid... that in my 
experience is a shockingly effective Faraday cage up through 1.2GHz.  In 
any case, tile roofs often have great heaping loads of metal flashing that 
you will want to be aware of.

My personal stealth experience is a CC&R'ed townhome with stucco walls and 
tile roof.  Any useful radiator needs to be as far away from either as 
possible.  My solution was to walk around the complex looking for all the 
parts of my roof that were hard for board members to see. Then I ran a wire 
along and around those places, and brought one end down to an auto-magic 
tuner that hung under the eaves in the back.  Performance sucked, but it 
sucked less than sitting around imagining what it would be like to be on 
the air.
