Of all the roofing materials on the market, metal has one of the longest projected life spans. If cared for properly, it could last upwards of 50 years. However, that still means that it will need to be replaced eventually, especially if unduly affected by the elements. To determine when yours has reached this stage, look out for these three warning signs.

How to Determine When Your Metal Roof Needs to Be Replaced

1. Loose Parts

With certain kinds of metal roofs, the panels are fastened to the home with screws. However, over time, the expansion and contraction of the metal panels can cause the holes around the screws to stretch out.

Loose panels can easily be blown around in the wind, as well as allow moisture to seep into the underlayment. They can also increase the risk of pest infestations. While retightening the screws may work temporarily, ultimately, the system will need replacement.

2. Widespread Rust

While resistant to mold and fire damage, metal’s vice is rust. If the painted surface has been worn down by the elements, moisture may make contact with the metal components, leading to corrosion.

Rusty metal is inherently weak, and your metal roof may no longer be able to protect your home from environmental dangers. If the rust covers more than 30% of your roof, your contractor might suggest starting from scratch. Reseal your panels regularly to avoid this issue.

3. Serious Storm Damage

If high winds knock down a tree or send a fence post flying into your home, it can leave severe damage behind. By denting the metal or leaving behind a gaping hole, it can cause the entire structure to become compromised. While your roof remains weakened by past storms, it won’t be able to protect you from future ones.
