Matt,

            I guess my questions are 1/2" plywood or 5/8" and how thick is the foam?  Oh and I assume its nominal 2X6 T&G?  Do you know how the plywood is attached?.....through the foam into the T&G?... to stringers, nailers or whatever they're called?

Hi Matt,
I've used these in the past when on a comp roof and there was no good way to get into the rafters (or TJI's in this case)

You might want to replace the screws with something shorter and beefier though to get more grip if you are only going into 1/2" plywood.

Cheers,
Dave

    Hi All,

    I've run into a roof-mounted job where the roof is built-up with
    the following:

    Comp shingle
    Plywood
    Foam board
    T&G (roof deck, but also interior ceiling)

    The beams that hold the t&g up are wide-spaced and not convenient
    for fastening the full extent of the array.

    This being the case, I was considering other fastening options and
    am writing to pick the collective brain of the Wrenches to see how
    others have addressed similar situations.

    One thought I had was to use the PLP Easy Mounting Foot and I'd be
    glad for any opinions on that or another solution.

    -Matt
