Putting one on tomorrow, but can't find info on how far apart the screws should be placed.

Screws will be driven into the rib only.

Sheets cover 36"

Re: Screw Spacing in Sheet Metal RooF

Just curious, is this corrugated tin, v-crimp or a 36 inch residential crown panel ? If its the residential crown you put the screw in the rib. If the screws have the rubber washer in the flat of the tin. With the rubber washer it wont leak. Only place a screw in the lap rib. Look at the link below.

I used the crown panel and put screws in the ribs, execpt for the ridge and eave, where the screws will go in the flats.
Too much hard work. ;)
