HI All, Im bidding a job that has an existing aluminum shingle roof. Im wondering how to properly flash the penetrations, and what to use for standoffs. We typically use Unirac 2-piece aluminum standoffs with Oatey no-calks on a comp roof. We have used S5 VB-47s for face-fastened metal roofs, but never encountered aluminum shingles yet. Ideas?

What a source of power! I hope we dont have to wait until oil and coal run out before we tackle that.-Thomas Edison
