Screw Seperation on Rake on R-Panel on the Roof

Guest User
What is the maximum seperation for screws on rake overlaping the R-Panel on the roof?

I assume you want to know what the screw spacing should be. Assuming that there is tape sealant between the rake trim and the roof panels, you should be good with a 20" spacing. That is the UL 90 rated spacing for the R panel sidelaps and they are watertight.
