I think the only limitation to using at "Escape Hatch" would be the size. Finding a flat area 24'x24' on an egg roof would be a challenge.
There would be only two reasons not to use a metal roof vent, the first would be price, they are more expensive but if you calculate in the cost over a lifetime of replacing the plastic covers on the originals the metal is much cheaper. Cost is the reason I manufactures use plastic and nor metal
The second is they do not let any light
in when closed, this feature may be desired or not. Where we camp it can be light
outside for over 22 hours a day, this feature is ideal in these locations to help get a full night sleep.
