Personally, I wouldn't be concerned with temps at the roof with that flashing. That stuff is rated for over 250°F and I don't think I've ever had a B vent anywhere near that hot at a roofline.

In my areas the one I have seen for B vent is a red looking one. I do not remember who makes it.

This link will take you to more flashing. http://pipebootexpress.com/?gclid=CKfYu ... FQodkVt8_A

If you will look in the roof forum you will find where I posted a photo and we talked about flashing.

Thanks for all the info, I had not seen the previous discussion. About a month ago I found a similar installation only this was on triple wall pipe from a wood stove. I wrote this as incorrect.
