Attic ventilation, and why roofers keep raising it
The cheapest thing you can do during a re-roof, and the one most likely to be skipped.
Get quotes instead
Three questions, up to three contractors, nothing charged.
Your request is in.
We are matching it now against roofing contractors working in Irvine and the surrounding area.
- Today, usually within the hour. The first contractor calls or texts the number you gave us. ASAP requests go out first.
- Up to three of them, no more. We cap it at three so you can compare without your phone melting.
- They come and look. Estimates are given after somebody has been on the roof, not over the phone.
- You decide, or you do not. There is nothing to cancel and nothing to pay us.
If you do not hear anything today, check your voicemail and spam folder — contractors often call from a mobile number.
Two openings, in balance
A roof needs air coming in low at the eaves and leaving high at the ridge. Intake and exhaust have to be roughly balanced; more exhaust than intake simply pulls conditioned air out of the house.
What happens without it
Trapped heat cooks the covering from underneath and takes years off it. Trapped moisture condenses on the deck, and over enough winters that softens the sheathing. In cold climates it is also what turns roof snow into an ice dam.
Why it gets skipped
It is invisible, it is not on the brochure, and it makes a quote look more expensive next to one without it. It is also, hour for hour, the cheapest way to make the next roof reach its rated life.
What to ask
What is there now, what should be there, and what is being changed. If the answer to the third question is nothing, ask why not.
What is it going to cost?
No cost, no obligation, and never more than three contractors.
