Proper attic ventilation consists of a balance between air intake (at 
your eaves or soffits) and air exhaust (at or near your roof ridge). 
The Federal Housing Administration recommends a minimum of at 
least 1 square foot of attic ventilation (both intake and exhaust) for 
every 300 square feet of attic space.
