The answer to 'metal roof cracked' is that a cracked metal roof is a common problem that requires prompt attention. The most common causes are thermal expansion and contraction, physical damage, and corrosion. Symptoms include visible cracks, leaks, and rust. Solutions may involve patching, replacing damaged panels, or in severe cases, a full roof replacement.
For minor cracks, a DIY repair using a high-quality sealant or roof coating may be possible. However, if the damage is extensive or the roof is older, it's best to call in a professional roofing contractor to properly assess and fix the issue. Attempting a complex metal roof repair without the right skills and tools can lead to further damage and safety hazards.
