Fixing a worn ridge vent and missing ridge cap shingles on a Cranford, NJ roof

The problem

From the ground, the roof looked fine. When we put a drone up and then walked the roof, we found a section of ridge with no cap shingles left on it at all. The ridge vent material underneath had broken down into loose fibers and torn mesh. That left open slots right over the roof deck, so rain and pests had a way in.

What we did

First we pulled off the damaged cap shingles and the old vent material along that part of the ridge. With the ridge open, we checked the framing underneath. Then we nailed new rolled ridge vent material down along the ridge. It lets attic air out and keeps the weather from getting in. On top of the vent we laid new hip and ridge cap shingles and sealed the joints. The new ridge matches the shingles that were already on the house.

Materials

Rolled ridge vent material, asphalt hip and ridge cap shingles, roofing sealant at the cap joints.

Common questions in Cranford

Do I need a new roof if my ridge cap shingles are missing?

Usually not. If the rest of the shingles are in good shape, we can replace just the ridge cap and vent, like we did on this Cranford job.

What does a ridge vent do?

It lets hot, moist air out of the attic along the peak of the roof. The vent material lets air through but keeps rain, snow and pests out.

How can I tell if my ridge has a problem?

Look for missing or lifted shingles along the peaks, pieces of shingle in the yard after a storm, or stains on the top-floor ceiling. A drone look or a roof inspection will tell you for sure.
