The answer to 'my ridge vent is failing' is that there are several common causes for a failing ridge vent, including damage, improper installation, or simply normal wear and tear over time. Symptoms can include visible cracks, gaps, or deterioration in the vent, as well as leaks or air drafts in the attic space. In many cases, the ridge vent will need to be repaired or replaced to restore proper ventilation and prevent further issues.
If the damage is minor, some homeowners may be able to make simple repairs themselves, such as sealing cracks or replacing individual vent components. However, for more extensive damage or if you're unsure of the cause, it's best to call in a professional roofing contractor to inspect the vent and recommend the appropriate solution.
