The answer to 'roof vent leaking' is that a leaking roof vent is a common problem that can have several potential causes. The most common issues are damaged or cracked vent seals, improper installation, or deterioration of the vent itself. Symptoms may include water stains around the vent, musty odors, or visible leaks during heavy rain.
To fix a leaking roof vent, the first step is to inspect the vent and surrounding area closely to identify the source of the leak. This may involve removing the vent cover or sealant. Small cracks or gaps can often be repaired with a high-quality sealant or caulk. However, if the vent is severely damaged or the issue is due to improper installation, it's best to call a professional roofing contractor to replace the vent and ensure a proper seal.
