Always check with your panel manufacturer but my advice is to pre drill them.		Todd Miller Isaiah Industries, Inc. 1/7/2012	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/16939/find/
+1 The more you can control the process on the ground (level, square, plumb, etc) the better the finished product will look on the roof. Pre-drilling takes more of the guess work out of the equation and allows for a more streamlined and finished product while on the roof. You will have enough to think about while up there.
