metal roof question: screw placement ...: "I have a carport that is a 3/12 pitch and ..." - Guest User (3/29/2015) | I Have An Existing Metal Roof and Have A Question

I have a carport that is a 3/12 pitch and comes off the side wall of my house garage...It has a shingled roof now...I was thinking of using metal...couple questions: 1) why not put te screws in the top of the large ribs instead of in the low part of the panel ?? Seems more likely to leak in the lower portion.. 2) the roof dead ends against the house facsia under a gutter...how do I dead end the metal so no water can get behind it ?

I would suggest a flashing up being the gutter and the drip edge of the higher roof, and coming out on top of the new roof by several inches. The problem with screws in the tops of the ribs is getting the screws in square and getting good a good seal of the grommet to the metal panel.

It might be best to remove the gutters and re-install. However, if you can get up behind the gutter a bit, that is good. I'd also try to get your underlayment behind the gutter. Rarely do I see the need for battens on the roof. Underlayment over the old shingles is good normally. I would suggest looking at synthetic underlayments as they will be thinner than felt and that may help you. Maybe sure that the drip edge on the upper roof leads into the gutter so that you are not directing water behind that gutter.
