Roof Ventilation Upgrade

What This Service Involves

Many homes here were framed with a couple of box vents and no real intake, which leaves the attic holding moist air all winter long. Upgrading means auditing what you actually have, then bringing the intake and exhaust into balance so airflow moves continuously from eave to ridge. We frequently find powered fans fighting against sealed soffits or gable vents short-circuiting ridge exhaust, both of which we correct as part of the redesign. When we reroof or work on an existing deck, we can convert scattered static vents to a clean continuous ridge vent for far better performance. The upgrade pays off as drier sheathing, fewer mold complaints, and a noticeably cooler upstairs during our increasingly warm summers.

Benefits

Corrects decades of under-ventilation common in older PNW housing stock; replaces mismatched or short-circuiting vents with a balanced design; protects insulation from getting damp and losing R-value; improves comfort in finished upstairs rooms year-round; often combines efficiently with a scheduled reroof

Our Process

1) Audit existing vents and measure the airflow imbalance in the attic; 2) Design a corrected intake-to-exhaust ratio for the roof; 3) Remove conflicting or redundant vents that short-circuit airflow; 4) Install the upgraded continuous exhaust and intake and confirm even draw

What Affects the Cost

Current vent configuration and how much must be removed; roof size and access difficulty; choice between ridge, powered, or hybrid systems; soffit condition and whether intake must be rebuilt; coordination with any concurrent roofing work

Best Time of Year

Late summer through fall lets us complete the upgrade before sustained rain tests the attic's moisture handling.
