[RE-wrenches] The perfect solar ready roof

[Chris Daum]

You are correct -- and there is a strong possibility of adding another layer
(1/2" or 3/4") of roofing material under the new metal roof.  High wind area
is a consideration, and I don't think those fake I-beams are meaty enough to
lag into.  Hence I request your input!

After re-reading your original letter Chris, it sounds like the roof
makeover hasn't happened yet. If that's the case suggest to the owner that,
based on the 100 years or so of combined professional experience of the PV
installer community, he should not use the engineered rafters or the 1/2"
decking if he's wanting PV on top. 
Pull out a copy of the International Building Code and show him. 
 
not a roofer,

 Dear Wrenches    
 have a composite (shingle) roof at hand, and the owner wants to upgrade it
to a metal roof and install a 5kw+ array on it.   The rafters are those
(sort of) particle board I-beams covered with 1/2" plywood (and shingles).
What's the best metal roofing you could suggest--and would you beef up the
wood to lag into?


Thanks for all your input.
