Just a note of caution here: "Tech" screws are "Tek" screws, which are
essentially a sheet metal thread following a pilot drill point, on a
hardened shank. They are intended for mounting only into metal, not
wood; the drill point isn't designed to self-pilot into wood, and the
drill section is too large in diameter for wood.<br>

Water has an optional mounting foot with five holes in it for what I
think Jeff Randall there referred to as 'Tech' screws to use in the
field between rafters. They are referred to as 'easy feet'. It is
designed to only attach into the roof decking, which I'm pretty
sure only required 1/2" OSB. He claims the same or better pullout
values as one lag per regular foot...there may also be tighter spacing
involved for the feet. The choices are 1 1/2" or 3" long, has a self
tapping point so no pre-drill. Add some of the peel and stick mastic
and it's a fast install.</font></div>

[RE-wrenches] Mounting to SIPs, revisited</div>
<div><br>
</div>
Esteemed Wrenches,
<div><br>
</div>
<div>We have a PV job in the works that will require mounting
racking to several roofs that consist of asphalt shingles laid over SIP
panels. The panels are standard 10" nominal thickness, with 9-1/4" of
foam sandwiched by 1/2 OSB on each side. The rub is that the underside
of the panels will be the finished ceiling (with 5/8" of wood over the
OSB). </div>
<div><br>
</div>
<div>I found a couple of threads in the archives discussing
mounting to SIPs, but most comments suggest through-bolting, and that
is not an attractive option in this case due to the finished ceiling
directly beneath.</div>
<div><br>
</div>
<div>The roofs in question are triangular in plan, and are fairly
small (~ 15' x 15' x 21')</div>
<div><br>
</div>
<div>Does anyone have experience with mounting directly to the
outer skin of a SIP panel? </div>
<div>Suggestions on the best way to approach this problem would be
appreciated. </div>
<div><br>
</div>
<div>Thanks in advance.</div>
<div><br>
