Secondly, can you put a ridge vent on a metal roof? How To Install A Ridge Vent For Metal Roofing. The ridge vent is only half of the venting system if that's the venting system you're going to use.

The safest way of venting a metal roof is installing a roof ridge vent. A roof ridge vent is static, but doesn't require cutting into the metal roof's middle.
