I have no experience with SIP but, There's a product I buy from Krannich that is excellent for difficult roofs where there is no point of attachment. 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
