Attic ventilation

An attic that can’t breathe ages the roof from the inside.

The sun drives heat into the attic for much of the year, and showers, cooking and laundry add moisture. When the air can’t move, shingles curl and blister early, moisture settles into the decking and insulation, and the air conditioner works harder in the rooms below.

How we fix attic ventilation

Finished shingle roof repair at the ridge
01

Air in low, out high.

Cooler air comes in through vents at the eaves and soffits and hot air leaves at or near the ridge, so the flow keeps going as the roof heats up. The two sides have to match: exhaust with no intake, or intake blocked by insulation or paint, leaves an attic stuffy however many vents are on the roof.

02

Check the roof and the attic.

A roofer looks at the vents from the roof and, where it can be reached, from the attic, photographs each one and explains the likely cause. Sometimes it’s one blocked vent; sometimes the system is missing a whole side.

Clear, repair, add, then flash.

The written scope and price say which vents to clear, repair, replace or add, and where. We free blocked intake, replace failed vents and add vents where the system falls short, then flash every vent that goes through the roof so it doesn’t become a leak.

On its own, or with a new roof.

Vents can be fixed on their own. When a roof is near the end of its life, we’ll tell you it makes more sense to plan the ventilation with a shingle roof replacement; vents installed with a replacement are covered by our 10-year workmanship warranty (call for details), and repairs carry the manufacturer’s warranty on the materials used.

Local roofers. Real accountability.

A roofer looks at your roof first, and you get photos and a written price before anything starts. One family-owned company answers for the roof, from the first visit to the walk across the finished roof with you.

“I was looking to replace my shingles roof in Encino and contacted a few roofing companies in the neighborhood. Out of four roofers, Quality Roofing Specialist was the only one that worked with my budget as well as my schedule. Their work was fantastic, and we love the outcome. They exceeded my expectations. I will definitely recommend to friends.”

Frequently Asked Questions

Straight answers about attic ventilation.

Who installs roof and attic vents?

A roofing contractor. Roof vents are cut through the roof deck and flashed into the roofing, so a poorly installed one is a leak waiting to happen. We install and replace ridge and roof vents, open or add intake at the eaves and soffits so the system stays balanced, and flash every vent into the roof. You get photos and a written scope and price first.

How can I tell if my attic isn’t ventilated well?

Common signs are upstairs rooms that stay hot, an air conditioner that runs nearly all day, a musty smell, damp insulation, stained decking and shingles that curl or blister. Some of these have other causes, so a roofer’s inspection, with photos, is the way to find out which one you have.

Do I need ridge vents or box vents?

It depends on your roof’s shape and the intake you already have. What matters is balance: air coming in low at the eaves and leaving high near the ridge. We recommend vents based on what the photos show and put the plan in your written scope.

Can you add ventilation without replacing my roof?

Often, yes. Vents can be repaired, replaced or added on their own. If your roof is close to the end of its life, we’ll say so and show you why it may be better to do the ventilation with a shingle roof replacement or a tile roof replacement.

Does a tile roof need attic ventilation too?

Yes. Any pitched roof over an attic, tile or shingle, needs air moving through it. Our roof inspection checks the vents on a tile roof the same way as on a shingle roof.

What about a flat roof?

A flat roof with no attic space has no attic vents to add. On a flat roof, how water drains matters more, so see our flat roofing services.

Does your warranty cover ventilation work?

Vents installed as part of a roof replacement are covered by our 10-year workmanship warranty (call for details). Repairs carry the manufacturer’s warranty on any materials used, which depends on the product and its warranty tier.
