Quote from: phalynx on January 29, 2008, 01:30:00 AMany tips on installing the metal correctly? I am going to use a snap-lock metal panels. They are 16.25" wide and will be 14' long. I am really concerned about it not being square or drifting off square. With 14' long pieces, I can't really follow a chalk line.

The main thing about metal is getting started square. If it is not then the end result can be very much to your dislike. If you sheeting or perlins are the same distance from you end rafter then decide how much overhang to aloow for the tin. I use 1" and 1-1-1/2" . Set a string line blocked out on each end to the desired overhang. Then move your tin after it is overlaped on the previous piece to that string line. Do not try to have too much of an overhang on the rafter tails or you will have to add extra facia to make the gutters work right.If you want to double check yourself half way through the process you can pull it some to get back on track. Measure from the sheet edge to the last rafter or sheeting edge on top and bottom. If it is the same you are good to go. If you see that it is running off then when installing the next sheet attach the top or bottom( depending on which way it is short)and before screwing down that end just lift it slightly out of the groove while pushing toward the direction that you need and then attach the screw. You can also pull in this fashion by going tthe opposite direction. You would be surprised how much you can gain just a little at a time.I know you can"t stretch metal but Oh yes you can of sorts.
