[RE-wrenches] SIPS panel roofs

[Chris Worcester]

Hi Dana,

I’d consider the DPW Easy Power Posts as each one takes 6  ¼” x 2” screws,
and if you use the fat ¼” metal roofing screws a lot of the strength is in
the metal to help with hold down. Triple rails under each row of modules
with Easy power posts at 16” to 24” o.c. depending on the roof’s pattern 

just a thought. I do wonder what their metal roof attachment method was. We
have used these on metal in high snow-wind load scenarios, but into plywood,
not OSB, using the # 14 x 1.5” Woodtite metal roofing screws. Good luck.

SIP ROOF INSTALLATION

 

I was asked to install on a SIP panel roof today. 5/8” OSB over 6” of foam
on a 9:12 roof pitch at 9800’ elevation with a Pro panel metal roof skin.
There is a finished ceiling underneath the lower side of the SIP roof panel.


I explained that it was not ideal due to the lack of good attachment etc.
They were not concerned and said “you’ll make it work!”

 

I have done SIP panels in new construction and we could install backing from
underneath and refoam.

My first thought was to do 2-2.5 times the normal L feet.

One thought was to use expanding moly-bolts.

 

Has anyone have experience attaching to SIP roof that was not prepared for
an array?
