[RE-wrenches] SIPS panel roofs

[Chris Mason]

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.
