Believe it or not, [I]I certainly don't[/I], there are no instructions on this across the entire web as far as I can tell. It's not immediately obvious how to do this correctly. I mean, good looking, leakproof.... correct. Sure, the average 'joe' is going to say "what's so hard?" But if you give the task to 10 guys who have never done it before, you're going to get 10 different ways to do this, a few of which will be complete ****-ups. Why so hard to find instruction on this? There are multiple planes and angles going on here, and that's even before considering the confluence of slopes on the hip roof edge. [ATTACH=CONFIG]3665[/ATTACH] Anyone able to point me to a source of PICTURES/DIAGRAMS that instruct how to do this? I've found many pictures of the final corner once accomplished, and a few explanations (without pictures... are you kidding me?), but nothing that actually shows the cuts being made step by step before the miter is assembled together. Obviously the corner cannot be a bent one or the drip edge itself would not be able to meet at 90 degrees. Has to be a full cut miter. So what is the best profile, with overlaps/tabs to cut in both sides?

I’ve lived in my house, it was built in 1954, since 1976 with little or no problems with the chimney. About 5 years ago I had a new furnace installed. High efficiency but not a real high efficiency one as it still had to go out the brick chimney. Now I started having a problem with the chimney brick faces falling off. From the ground I can see at least 2 complete faces that have done this. Could the new furnace be causing this to happen? If so is there something such as a liner that I can have installed to prevent this. DLH
