The answer to 'ridge vent cracked' is that a cracked ridge vent is a common problem that can allow water, pests, and air leaks into your home. This is often caused by age, weather damage, or improper installation. Symptoms include visible cracks, leaks, or drafts around the ridge vent.
For minor cracks, you may be able to repair the vent yourself using a flexible sealant or caulk designed for roofing materials. However, if the vent is severely damaged or the underlying roof structure is compromised, it's best to call a professional roofing contractor to assess the issue and replace the vent as needed.
