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?
