Metal roofing is one of the most durable types, but it isn't impervious to all damage over time. If you keep up with maintenance and promptly perform roofing repairs, these structures will can more than 50 years. However, you need to watch for signs of damage, which is further described in the list below.  

3 Metal Roofing Issues to Watch For

1. Corrosion

Metal roofing is coated in an anti-corrosive finish that protects it from moisture that causes rust build-up. However, when this finish is scratched over time, water can still seep through these cracks. 

You may notice small patches of rust appearing on your roof, and if you notice these issues, you need to have the affected panels replaced as soon as possible. The longer you ignore this issue, the corrosion will continue to worsen due to the finish not being repaired. 

2. Leaky Ceilings

If you spot discoloration from water damage in your attic or the ceiling of your top floor, it could be a result of a leaky roof. This occurs when metal roof panels fall out of place, leaving tiny crevices where water can find its way through. This is especially common during rainstorms when wind and fallen debris knock the panels out of place. 

3. Oil Canning

If you notice that the flat panels that make up your metal roofing are starting to appear distorted and wavy, it may be an occurrence known as "oil canning". This is caused by improper roofing installations when metal panels are placed too close together. 

When they expand and contract in low and high temperatures, they don't have room to change shape, which leads to this distortion. While this usually doesn't have any structural effects, it does reduce the attractiveness of your roof's appearance.
