Attic Ventilation

"A balanced system of intake (soffit) and exhaust (ridge, gable, or power) vents that moves air through the attic to manage heat and moisture."

American English entry — uses US spelling (color, gray, favorite, neighborhood) and US units (sq ft, gallons, ZIP code). Optimized for homeowners and painting contractors across the United States.

Color definition in detail

US code generally requires 1 sq ft of net free vent area per 150 sq ft of attic floor. Poor ventilation accelerates shingle aging and causes peeling paint on soffits and fascia from trapped moisture.
