The answer to 'why is my ridge vent leaking' is that the ridge vent may have become damaged, improperly installed, or worn out over time. Common causes include cracked or broken vent components, gaps around the vent, missing sealant, or improper ventilation that leads to moisture buildup.
Ridge vents are designed to allow hot air to escape the attic while preventing water intrusion. If the vent is leaking, it can lead to water damage, mold, and other issues in the home. Addressing the problem quickly is important to prevent further damage.
