Hi Dana, Id 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 roofs 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.

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 youll 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? ---------------------------------------------------------------------------- Dana Orzel Great Solar Works, Inc - NABCEP # 051112-136 E - d...@solarwork.com - Web - solarwork.com O - 970.626.5253 C - 208.721.7003 "Responsible Technologies for Responsible People since 1988" P Please consider the environment before printing this email.
