Is this compatible with a EPDM roof?
You could use this with EPDM, but you would need to consult your roofer on how best to waterproof/seal over the metal flange.
It would be possible to stick a patch of EPDM over the flange using some contact adhesive.Or there is an option with an EPDM flange you can view by clicking here.

Does this flat roof vent need a ‘mushroom’ on the top to prevent rain etc or is this all that is required? Thank you.
This item is provided with a hood/cowl on top so no need to purchase anything extra.
