What ridge means
The ridge is the level top line of a roof where two slopes meet. It is covered with ridge cap shingles or metal, and is often where the attic exhaust vent sits.
Also called roof ridge, peak.
Where it matters on a roofing job
Ridge length drives two lines on your materials list: ridge cap and ridge vent. Measure it separately from hips. A ridge that sags in the middle is a framing problem, not a roofing one, and is worth pointing out before you put new shingles on it.
