I'm new to the list, and glad to find it. I'm in the middle of re-shingling my house. I've spent a lot of time on the Internet, looking at how to do each part of the job, researching it until I'm exhausted. I've found plenty of information on the Internet about step flashing and how to do it properly. But I've not found much information regarding how to properly flash the dormer corner. The one detailed guide I found was this:
http://www.familyhandyman.com/DIY-Projects/Home-Exterior/Roofing/roof-flashing-techniques-for-outside-corners/Step-By-Step. I used the first method mentioned, what this site calls the "wrapped corner method".
Unfortunately, it isn't working well for me. I'm using aluminum flashing and I can't get a really nice, sharply delineated crease in the flashing -- there is more of a bend, due to a slight curve in the ice and water shield below it. As such, when I wrap the flashing around the corner, it tears a little bit where the wall meets the roof. After repeated efforts, I simply filled the little rip with roofing sealant. But it is bothering me.
Is there a preferred method for corner flashing? Can anybody give me any pointers?
