I’ve used Pro Solar Rail in a similar way, it has a flat bottom and you can place it directly on the roof with butyl tape under the whole length, then fasten as often as you determine is needed. Rails run from peak to eave, and modules go in landscape. We mount the rails as close to the peak as practical, as it reduces the amount of water that can get to the rail from above, after that, it’s a continuous Butyl strip compressed by the rail, and the water would have to get in from the sides. You don’t splice rails either, just set the next rail ¼-1/2” down roof to allow for thermal expansion. No leaks so far.

It is called Xpress rail. The older product, which I don't think they sell anymore but I bought out everything they had, could be attached by pop rivet or self drilling metal screws. You drilled a hole every six or twelve inches and riveted it right onto metal roof sheeting. You back it with double sided EPDM tape. It is amazingly strong and probably as well attached as the roof itself. http://www.everest-solarsystems.com/fileadmin/k2systems/PDF/public/Produktblatter/USA/XPressRail_US3_0813.pdf On Wed, Dec 16, 2015 at 7:45 PM, Dana <d...@solarwork.com> wrote: 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? ---------------------------------------------------------------------------- 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. _______________________________________________ List sponsored by Redwood Alliance List Address: RE-wrenches@lists.re-wrenches.org Change listserver email address & settings: http://lists.re-wrenches.org/options.cgi/re-wrenches-re-wrenches.org List-Archive: http://www.mail-archive.com/re-wrenches@lists.re-wrenches.org/maillist.html List rules & etiquette: www.re-wrenches.org/etiquette.htm Check out or update participant bios: www.members.re-wrenches.org -- Chris Mason NABCEP Certified Solar PV Installer™ Solar Design Engineer Generac Generators Industrial technician www.cometsolar.com <http://www.cometenergysystems.com> 264.235.5670 869.662.5670 Skype: netconcepts _____ No virus found in this message.
