Attic Vents

980 Views 4 Replies 2 Participants Last post by  Murdy
My attic is 1040 square feet. I have 2 large gable vents on either end of the attic and 3 static vents (mushroom style) along the ridge, but no soffit vents. My understanding is that 1 vent per 300 square feet is sufficient. Is this sufficient? If not, how many would be enough, in light of the other venting?

My main concern is lack of soffit venting, so basically everything is high, so I suppose I should stick a few in there. By my calculations, 3 to 4 would be right. I'll see if I can find something similar to what's in there and get specs. It's an old house and the attic has always been dry, so I'm probably overthinking it. Thanks for the advice.
