    Can I make the flashing from a regular thru the roof kit work with some fabricating? I set everything up and my pipe is crooked where it comes thru the roof, perfectly straight in the house...

    You can cut the back of the flashing to move the pipe vertical and than there should be a collar that will fit tight over the pipe and cover the gap that is now in the front of the pipe.

    Flashings usually come in two cants. One for shallow pitched roofs and one for steeper pitched roofs. Be sure you are starting out with the steeper pitch roof flashing.

    Maybe a trip to the local metal fabrication shop is in order here. You give them the pitch and pipe diameter, they can make an exact flashing. Those "universal" flashing cones look like chit on most applications, IMO. I'm betting you could get a nice one made (out of stainless steel, even) for under 80 clams at a local shop. I had the big flashing for my stone chase made at a local fab shop out of stainless steel....yes it is big, and it was expensive, but it fit like a glove and it will long outlast my soul on this earth.....

    I understand having one made for a chase, but a roof flashing? Never heard of that.
    Flashings are made for 0-6 pitch and 7-12 pitch. We do dozens of them a year and It's very rare that one looks odd even if it has to be modified a little. The Super-Vent flashings from Big Box stores are little unattractive, I prefer to use Dura-Tech or Excel flashings. As long as you have the appropriate flashing you can trim it out a little to make it plumb.

    The shop I got my chase top from makes flashing cones for woodstoves, out of stainless steel. Had I know that when I put my woodstove in the kitchen, I'd have had them make me one. When redo the roof down the road (putting a tin roof on in 6-8 years from now), I'll be having one made......

    Excel makes SS flashings and a killer metal roof flashing!

    I love copper.....I had a copper one ordered for the stone chase (it would've been gorgeous against that stone), but the $800.00 price spooked me away from that option!

    Heres some nice copper work I found on the 'net...

    Just had a copper kitchen sink installed. The American Standard "Americast" sink was driving my wife crazy. No price too high for tranquility in the kitchen!

    Copper is beautiful, but let's stick to roof flashings and be sure that OP has his question answered.

    Are you sure you don't have the flashing spun the wrong way? If you do have it set in proper position, and can trim a little to fit off the back side, go for it. If you have to trim a lot off, you may have issues with leaks if it is not tall enough to handle the weather. If you need the steep roof type, just go buy the correct one. Do it right now, and save yourself grief down the road.

    I used to make all kinds of stuff out of copper, tern coat, lead coated s.s. etc when I was roofing. I miss that part of that career.
    Don't know the size of your chase, but $800.00 seems a bit steep.
    Maybe I need to go into the copper accessory business.

    Copper's expensive these days.


    For the original question - I bought the Duravent A frame roof flashing kit for my house from a chimney supply place a couple years ago. It was stainless steel and cost about $180. It would fit 6" chimneys on real steep roofs - mine was 21/12! They should have one that will work fine for your pitch.

    Hogz, it was so expensive in part because the sheet of copper needed to make the top was bigger than 4'x 8'.......they would have had to order an oddball sheet (I think it was more like 5'x 9') which would have required special shipping, etc.......

    Either way, I'm happy with the stainless, its all TIG welded and looks great, plus will last several lifetimes......but it would have looked really nice with the copper chase top, copper wrap on the pipe, copper storm collar and copper cap! I love copper!

    Personally, I would have just ordered 2 sheets enough to splice together to make the same piece. Or even a roll and make in several pcs. Any seams would be soldered(done miles of that). We used to use the old school hot pots with the hand irons. No torch, no electric. Just charcoal in a hot pot, irons in the charcoal to heat up and solder away with bars. Done right, will last 100+ years. I been eying up copper things I want to do around here. A chimney cap to cover the stone cap being one of them. Copper is expensive, and it has been a while since I used any, but $800.00 still seems steep.

    I thought the price was steep, too, so I stayed away from that and went with the stainless. I kicked around making it out of several seamed and soldered pieces, but I wanted it out of one piece. Either way, if you got the jingle, copper is the way to go....

    Otoh, certainly makes the idea of a class A chimney for a stove a lot more palatable on a house you wouldn't consider it for otherwise. (Didn't realize something like these were even an option).

    Sorry, but they haven't been made of pure copper for a number of years now.
