Roofing Glossary

Ridge

The ridge is the highest horizontal line of your roof — the peak where two sloping planes meet. It is both a structural junction and, on most modern roofs, the location of the ridge vent that exhausts hot air from the attic.

The ridge is capped with ridge cap shingles — thicker, pre-bent shingles designed to straddle the peak and shed water to both sides. Because the ridge takes the most wind exposure on the roof, ridge caps are often the first shingles to fail in a storm.

On vented roofs, a continuous ridge vent runs the length of the ridge beneath the cap shingles, providing exhaust ventilation for the whole attic — the outlet half of a balanced ventilation system.

Why It Matters

Missing or damaged ridge caps leave the most exposed seam on your roof open to wind-driven rain. After any major wind event, the ridge is the first place to check — our storm damage guide walks through what to look for.

What to Watch For

• Missing or cracked ridge cap shingles
• Ridge vent sections lifted or displaced
• Daylight visible along the ridge from inside the attic

A Maryland Note

Maryland's coastal storms and summer thunderstorm gusts punish ridge caps. High-wind-rated ridge cap installation matters here.
