Hi everyone-- I’m looking to get advice on the differences between eyebrow vs. O’Hagin vs. ridge vents.
I’ve got three bids from contractors each of whom suggest different vents. I’m looking to re-roof with Landmark TL. I have two gable vents, gable fan and two whirlibirds if that makes any difference. Each of the three contractors swears by their vent suggestion and says that theirs is the best. I’m confused and not being in the roofing business want to hear from you what you think. Is one vent superior to the others? BTW, no mention was made about blocking the gable vents. however, all of them suggested to take out the whirlibirds. I also have exterior wall vents all along the perimeter of my house at the attic level. My current roof is metal on top of shake.
I live in Santa Clara, California. Thanks in advance for your help!
