<div dir="ltr">We've found that in the Bay Area that deck-mount solutions typically pencil out structurally (via a structural professional engineer) as long as the deck is 1/2" plywood or thicker, assuming we have all the info on how the roof is constructed.

<p>Matt,</p>
<p> 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?<br>

<div>Hi All,</div>
<div><br>
</div>
<div>I've run into a roof-mounted job where the roof is
built-up with the following:</div>
<div><br>
</div>
<div>Comp shingle</div>
<div>Plywood</div>
<div>Foam board</div>
<div>T&G (roof deck, but also interior ceiling)</div>
<div><br>
</div>
<div>The beams that hold the t&g up are wide-spaced and
not convenient for fastening the full extent of the
array. <br>
</div>
<div><br>
</div>
<div>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.</div>
<div><br>
</div>
<div>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. <br>
