Ridge Cap Shingles

Ridge cap shingles are the finishing shingles that straddle the peak of your roof. They are thicker and pre-bent to fold over the ridge, shedding water down both slopes while covering the vulnerable seam where the two roof planes meet.

The ridge is the most wind-exposed part of the roof, so ridge caps take the worst beating in storms — they are frequently the first shingles to crack, loosen, or blow off. On vented roofs, ridge caps also cover the ridge vent, so damaged caps can compromise ventilation.

Premium ridge caps are thicker, with stronger adhesives and higher wind ratings than standard caps. They also give the roofline a cleaner, more dimensional finished look.

Why It Matters

A roof can look fine from the street while its ridge caps are failing. Because caps are quick to replace, catching damage early is a cheap fix — ignoring it invites wind-driven rain straight into the ridge seam.

What to Watch For

• Cracked, curled, or missing cap shingles along the peak
• Caps that lift or flap in wind
• Exposed nail heads along the ridge

A Maryland Note

Maryland's thunderstorm gusts and coastal storms punish ridge caps. If your roof is over 12 years old, have the ridge inspected after major wind events.
