The answer to 'roof vent damage' is that roof vents can become damaged for a few common reasons, such as weather exposure, poor installation, or age. Symptoms of roof vent damage include leaks, cracks, or the vent becoming loose or detached from the roof. Solutions may include repairing or replacing the vent, depending on the extent of the damage.
For minor issues like a cracked vent cover or loose fasteners, a homeowner may be able to make simple repairs themselves. However, for more significant damage like a vent that has become completely detached or is causing leaks, it's best to call a professional roofing contractor to assess and fix the problem properly.
