The answer to 'metal roof leaking' is that there are several common causes for a metal roof leak, including improper installation, damaged fasteners or sealants, corrosion, and physical damage. Symptoms may include water stains on the ceiling or walls, musty odors, and visible leaks during rain. Solutions can range from DIY repairs to full roof replacement, depending on the severity of the issue.
For minor leaks, homeowners may be able to fix the problem themselves by replacing damaged fasteners, resealing seams, or applying a roof sealant. However, for more extensive damage or if the source of the leak is unclear, it's best to call in a professional roofing contractor to inspect the roof and provide the appropriate repair solution.
