The most common way to vent a roof. The International Building Code requires one vent for every three hundred square feet. With the humidity we have down here, this is a beneficial way to go because with these vents we can also add attic fans. We can add as many as one attic fan every 800 square feet to cool down in the summer.
The biggest mistake roofers make while venting is adding a ridge vent and stopping there. The difference between the ridge vent at the peak and the mushroom vents is the mushroom vents circulate air. Ridge vents just release it. The intake needs to come from somewhere. If the soffit vents aren’t cut or insulation is covering them, moisture will build up in the attic and the plywood will begin to mold.

Looks can be deceiving. Although a roof may look great on the outside, without proper ventilation, you can be exposing your family to mold and other attic condensation.
Insulation is important and a necessity in our dry humidity. Baffles or “air tunnels” are used when in the venting process to ensure the soffits can breathe while maximizing the square footage of insulation.
