Ridge vent or box vents: which exhaust the estimate should name

Livingston, Florham Park, and New Providence colonials and split-levels often mix old box vents with a later ridge cut. The decision on the estimate is which exhaust system will stay, which will be removed, and whether soffit intake matches the exhaust so the attic can breathe.

- Do not mix competing exhaust paths without a plan

Exhaust without intake is not a ventilation plan
Ridge vents and box vents only work if air can enter at the eaves. A bid that adds a ridge vent while leaving blocked soffits still leaves a hot attic. Ask how intake is opened or restored.
Do not mix competing exhaust paths without a plan
Leaving box vents beside a new continuous ridge can short-circuit airflow. The scope should say whether old box vents are removed and capped or intentionally kept for a reason.
What the written ventilation line should include
Name the exhaust type, the ridge cut length if used, and the soffit or intake work. A Florham Park or New Providence lump sum for “vents” hides that choice.
