The answer to 'why is my metal roof damaged' is that metal roofs can become damaged for several common reasons, including corrosion, impact damage, and improper installation. Metal roofs are highly durable, but they can still experience issues over time.
Corrosion is one of the most common problems with metal roofs, especially in coastal areas or regions with high humidity. The metal can start to rust and degrade, leading to holes, cracks, and leaks. Impact damage from hail, falling debris, or even foot traffic can also cause dents and punctures in the metal. Improper installation, such as using the wrong fasteners or not properly sealing the roof, can lead to leaks and other problems down the line.
