Asphalt shingles are a popular roofing choice because they are durable and cost-effective, but ridge vent leaks can sometimes occur and cause issues. Ridge vents are installed at the peak of a roof to allow hot, moist air to escape from the attic, helping to regulate temperature and prevent moisture buildup. If you notice water stains on your ceiling or find moisture inside your attic, it could be a sign that the ridge vent isn’t properly sealed or that the shingles around it are damaged. Common causes include improperly installed ridge vent components, missing or broken shingles, aging sealant, or wind-driven rain getting through poorly sealed gaps. A simple way to check for leaks yourself is by inspecting the ridge vent area from the attic on a dry day, looking for any visible daylight or signs of water damage. From the roof, look for curled, cracked, or missing shingles near the ridge vent. Wearing proper safety gear, you can check that nails securing the ridge vent aren’t loose or popped out.
If you suspect a ridge vent leak, it’s usually best to call a professional roofer who is experienced with asphalt shingles and ventilation systems, especially because incorrect repairs can void some roof warranties or lead to new problems. When consulting a contractor, ask if they conduct a thorough inspection of both the ridge vent installation and the surrounding shingles, including underlayment condition, before making repairs. Also, inquire how they ensure the ridge vent will maintain proper airflow after the fix, as a watertight but rigid seal can sometimes restrict ventilation. A reputable roofer should offer a clear explanation of their repair method and warranty options for any work done, so you feel confident both about keeping your roof leak-free and preserving its long-term performance.
