The answer to 'why is my ridge vent' is that there are several common causes for issues with a ridge vent, including improper installation, damage, or blockage. Symptoms may include leaks, drafts, or poor ventilation in the attic. Solutions can range from minor repairs to complete replacement, depending on the severity of the problem.
If the ridge vent was not installed correctly or has become damaged over time, it may not be effectively ventilating the attic. This can lead to moisture buildup, mold growth, and other issues. Blockages from debris, animals, or improper insulation can also prevent the ridge vent from functioning properly.
