[RE-wrenches] The perfect solar ready roof

[Kristopher Schmid]

What about screwing in double 2x6s flush to the roof deck between the beams
where your feet will attach and lag bolting into that?  Definitely check
with the beam manufacturer first, though.

In general, you shouldn't drill or cut the flanges on engineered wood beams.
I think that eliminates lag screws into the rafters. They probably wouldn't
have the same pull-out strength as a lag screw into a conventional rafter,
either.

Dear Wrenches:

I 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.
