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. A ridge vent needs a continuous air supply from the bottom of the roof edge on both sides of the roof to work– often called soffit vents.
Likewise, do you need a ridge vent with a metal roof?
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.

Can you put a metal roof over shingles?
