Metal roofing is designed to last for several years as long as it has been maintained properly. However, like many other household items, a time will come for you to replace the roof with a newer one. But how do you know if your metal roof needs to be replaced? Truthfully, this can be quite tricky. Nonetheless, here are some signs that can indicate it’s time to replace your metal roof.

1. Discolored and corroded material

If you notice discolouration or corrosion on your metal roof, this can signify that your roof is rusting. When this happens, it can weaken the structural integrity of your roof and eventually lead to cracks, holes or leaks. These exposed spaces may also allow water to enter your home through the corroded and discoloured sections. Therefore, if you notice any rusting on your roof it may be time for a replacement.

2. Your roof is too old

Generally, most manufacturers will tell you that their roofing materials can last for about 30 or more years. You should take note of the projected lifespan of your roof. Once it is over 30 years old, you should start looking to replace your roof. In some cases, you may need to replace your metal roof earlier. For instance, if you live in a place that experiences extreme weather conditions such as acid rain or heavy snowfall, it can increase the rate of wear and tear on your roof.

3. Flimsy and brittle material

When in good condition, your metal roof should be thick and dense. Unfortunately, corrosion can damage the steel of metal roofs, forcing them to be brittle and flimsy. This causes the roofing material to crack or degrade easily and quickly, leading to a wide variety of problems such as holes and leaks in your home. If you notice that your roof is flimsy and brittle you should consider replacing it immediately.

4. Loose panels

Much like loose or missing shingles, loose panels on your metal roof can cause major problems. Loose roofing panels can happen because of rainstorms, high winds or heavy snowful. Keep in mind that loose roofing panels will likely lead to leaks, which can also damage some of your household items.To prevent further damage to your home, make sure you replace your metal roofing as soon as possible.

5. Worn paint

Paint acts as an extra waterproof coating for metal roofs. However, unstable temperature, falling debris, and other factors can make the paint of your roof wear out. Consequently, your roof will lose its additional coating, and water may start leaking into your home.
