The answer to 'why is my ridge vent wind damage' is that the ridge vent on your roof may be damaged or improperly installed, causing it to be vulnerable to high winds. Ridge vents are designed to allow hot air to escape from the attic, but if they are not securely installed or have become worn over time, strong winds can lift or tear them off the roof.
Some common causes of ridge vent wind damage include improper nailing or fastening, deterioration of the vent material, and inadequate roof structure to support the vent. Symptoms of ridge vent wind damage may include cracked, missing, or flapping sections of the vent. If left unrepaired, this can lead to leaks, further roof damage, and decreased energy efficiency.
