Roof vents 101 The standard roof vent is good for 300sqft of enclosed attic space so you don’t need to go crazy putting them in but at the same time you need to make sure you have enough. They should go on the side of the roof where you won’t really see them They should be evenly spaced along the roof #roof #vents #101 #build #house #home #custom #framer #framerlife #contractor #contractorsofig #framersareadyingbreed #safety #roofer #math #even | Dubreuil Contracting
