Ridge

In Plain English

The peak or top line of a sloped roof where two slopes meet — the highest point of the roof.

Definition

The horizontal line at the apex of a peaked roof where two sloping roof surfaces meet. The ridge is the highest point of the roof and runs parallel to the eave. Ridge caps (shingles, tiles, or metal) cover the joint at the apex and must be properly installed to prevent water and wind infiltration. Ridge vents along the ridge allow hot air to escape from the attic.

Example

A continuous ridge vent was installed along the full 60-foot ridge to provide balanced attic ventilation with the soffit vents below.
