[RE-wrenches] Goofy roofing

[Benn Kilburn]

August, et al;
If the purlins are only 1"x4" or 1"x6" or....1"x anything, are you only relying on the 1" purlin as the attachment point or are you hitting the vertical trusses below the purlins?

We are working on a corrugated roof right now and using a Schletter roof bracket. The name of it escapes me at the moment. Maybe FixT?  
We are attaching to purlins which are 2"x6".  I wouldn't think 1"x anything would provide enough pull-out?

If you have a corrugated metal roof, we’ve used S-5 CurruBrackets screwed through the metal and into the purlins and then either run the solar rail up and down the roof or install a sub-rack system (with strut or angle aluminum) perpendicular to your solar rail.

Pretty clean installation however for some reason he ran 1X6 stringers across the roof  on the 1/2" plywood deck spaced about every 4 feet (as you go from ridge to eaves).  Of course the roofing screws are at the stringers.  I'm sure he had a great reason for doing so.  So now I have been asked to install an array on this roof.  You can feel how "soft" the roof is as you walk on it of course because you are walking on air-below-metal for most of the roof.  Stringer locations don't jive with possible feet/post locations for rail.  I'm usually pretty good at problem solving but I'm accepting ideas.
