I am looking for information about flashing for the exhaust from a Tankless Water Heater as it passes through a metal roof. The current flashing is a rubber like material. Are these types of flasings good for the elevated temperatures with the exhaust from these heaters.

Some are designed for high temp. You can also use an exhaust pipe with an insulated wall	Todd Miller Isaiah Industries, Inc. 1/21/2010	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/14383/find/
Before: HVAC guys cut holes in the roof for the pipes. This was a temp. fix.	Guest User 1/23/2010	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/14384/find/
After: I made a soldered boot from galvanized steel to fit over the pipes. Then painted to match. The holes here where already cut so I had no choice, but you should try to arrange your Z-Bar so water flows around it easily - possible a diamond shape over a seam. This is one option.
