The answer to 'my ridge vent is failing' is that there are several common causes, including improper installation, damage from weather or debris, and normal wear and tear over time. Symptoms may include leaks, moisture buildup, and decreased ventilation in the attic. Solutions can range from simple repairs to full replacement, depending on the severity of the issue.
If the ridge vent is only mildly damaged or showing minor signs of wear, some homeowners may be able to make basic repairs themselves. However, for more significant problems or if you're unsure of the cause, it's best to call in a professional roofing contractor to properly diagnose and fix the issue. Improper repairs could lead to further damage or safety hazards, so it's important to have an expert assess the situation.
