What kind of roof vent do I need for a channel drain metal roof?

Question:I need to know what kind of vent i need for a metal roof I will put on soon. It is for the vent from the hot water heater? Can some help and show where some photos are?

Answers:
The flashing should come from the metal roof installer or manufacturer but you can use any standard vent. I assume you mean flue and it is a double wall type B (pretty standard water heater vent unless it is a condensing water heater then you need to contact the manufacture for a recommendation). Briedert makes one of the best type B termination caps.

Good luck. Hope this helps.
