Peak Flashing - Need Help Making

[ocafra]

To all those with circular peak chimneys. I have a Duratech Stainless steel double wall 10" diameter (Outside) Chimney. The roof is completely done now and chimney sealed over as I cannot figure out how to flash the peak hole.

I am able to figure out how to cut the angled storm collar. What I cannot figure out is how to cut the flashing base so that when it is bent to the roof pitch, is makes a matching 10" diameter circle which the storm collar can be welded to. Hence I am reaching out for help ideas. What have other done? Perhaps I am approaching this completely wrong so other ideas would be welcomed.

I have searched the site, and found a PDF, but does not show how to create the collar to flashing connection.

Not sure if it's any help, but I used a weathering slate with high-temperature PVC cone. You can get these specifically for flue pipes. Even at the angle of the roof pitch, the cone is still flexible enough to give a good seal right around the pipe - which you can augment with high-temperature silicone. The aluminium sheet, you fold/compress to fit the profile of your roof tiles. (Sorry it's not a very good picture.)

Looks like you installed on the slant side, not the peak...Yes?

Re: Peak Flashing - Need Help Making

You have not divulged the pitch angle of your roof, nor the radius of your ridge tiles. Therefore, this method may - or may not be suitable for your design. (From your reply I would assume not.) For all I know, you might have a barrel-vault roof - which will still have a peak, of course...

Ahh yes, I did leave that out. I trying to keep it simple to solicit solutions. I can adjust the angles and radius at a later point. I simply was trying to solicit advice on how to approach flashing a peak 2 sided flashing (versus a slant with a one sided flashing). For now I am considering going out to get a storm collar to place over a flat roof flashing (similar to yours), that I can custom cut the extended edges to place over a square box, that I can custom cut to fit on the peak of the roof. I was just hoping there was a more simple way.

Thank you for responding....and I wish I could have your roof. Love the tiles!!!
