The answer to 'why is my metal roof leaking' is that there are several common causes, including damaged or loose fasteners, gaps or holes in the metal panels, and issues with the sealant or flashing. Metal roofs can develop leaks over time due to normal wear and tear, weather damage, or improper installation.
Some common symptoms of a leaking metal roof include water stains on the ceiling or walls, dripping water, and visible damage to the metal panels. To fix a leaking metal roof, you may need to replace damaged fasteners, seal gaps and holes, or re-seal the flashing. In some cases, more extensive repairs or even a full roof replacement may be necessary.
