No matter the style or type of roofing material, Cor-A-Vent has a vent application to fit your needs. Proper ventilation protects your home from damage. Roofs and attic spaces have two major enemies in all homes: heat build-up and moisture accumulation. Installed, the low-profile vent provides maximum ventilation area and is nearly invisible. There are no connectors to line up...and you can nail or screw right through the vent without compression.
