<p dir="ltr">Can you get them to switch to a standing seam metal roof?  Then use seam clamps...problem solved!  And it's a better roof as well....<br>
Good luck.</p>

   We have done them, but our method only works when the interior is<br>
unfinished, for (I guess it depends on the customer) aesthetic reasons.<br>
I had aluminum "plates", 8"x8" and 1/8" thick made up by a local<br>
fabricator. We also fabricated flashing for the topside using 12"<br>
aluminum. We used threaded bolts running through the SIP (9 5/8") to<br>
another 8"x8" metal plate  on the underside. Unfortunately, this will<br>
not be a finished look. The underside of the roof we installed on was<br>
the underside of the SIP (sheathing). 8 years later, this roof remains<br>
leak free and full of modules......There are obviously more details to<br>
the install, but I don;t think this method will work for you.....<br>
