Metal roofing provides an aesthetically pleasing and extremely durable roofing solution to your home. However, like all types of roofing materials, extended weather and water exposure can cause your metal roof to begin to break down, which can cause all sorts of problems to the interior of your home. Understanding the warning signs associated with a worn or old metal roof can help you identify the problem and have your roof replaced before it becomes a serious and expensive problem to fix.
Metal expands with temperature fluctuations to a greater degree than other types of roofing materials, which means that after excessive exposure to winter-summer season changes, the seams of your metal roofing can begin to separate from each other. If you notice that there are loose or even separated seams between individual sections and panels of your metal roof, you may want to look into replacing it, as any sort of loose seam greatly increases the risk of water entering your attic.
If there are any pools of standing water on your roof, you should contact a professional right away to look into replacing that part of your roof.

Water will only stand on a roof if the roof has either been installed improperly or has become misshapen due to age and wear, creating a flat area that prevents water from draining properly. Water that is allowed to stay on your roof can cause all sorts of problems: firstly, it can find a way into your attic, where it can cause water damage and mold growth, and secondly, it can place an increased amount of strain on your roof itself, increasing the risk of a collapse.
The biggest sign that you need to replace your metal roof is if you can find any signs of rust or corrosion on the roofing material itself. Rust spreads just like a disease, eating up the metal of your roof rapidly if left unchecked. Depending on how far the rust has spread, you may be able to only replace individual sections of your roof, which is much less expensive and less time consuming than replacing the entire roof. In the future, to proactively protect a metal roof from rust and corrosion buildup, you should have it treated with an anti-rust sealant at least once a year, usually right before any period of heavy water exposure (i.e. spring rains and winter melts).
