Signs You Need to Repair Your Metal Roof

Metal is a popular roofing material that provides a high degree of durability and an increased aesthetic appeal when compared to traditional asphalt shingled roofs. However, like all building materials, metal can become damaged and break down over time due to general damage and age. A damaged metal roof can let water seep into your home and cause a number of problems on the interior, so it's a good idea to have your metal roof repaired as soon as it becomes damaged. Thankfully, there are a few things that you can look for to help determine when it's time to call a roofing professional to repair your metal roof.

Loose Seams

Get up on the roof and inspect the seams where panels of your roof come into contact with one another. Like most materials, metal will contract and expand as the temperature fluctuates, which means that the panels of metal roofing material can begin to separate, leaving a space for water to enter your home. If you see any sort of gap between the segments of your roof, you should have a professional come in immediately, as water that seeps in can cause structural damage to the supports of your roof and quickly become a more complex and expensive problem to fix.

Standing Water

If there is any sort of standing or pooling water on your roof, you need to have a roofing contractor look at your roof's drainage system as soon as possible. Water sitting on your roof can increase the amount of pressure placed on specific sections of the roof, and can also wear away the corrosion resistant layer on your roof (if your roofing material has a rust protection layer, that is). The issue usually lies with some sort of warping of the actual metal that prevents water from draining through your roof's gutter system properly.

Rust and Corrosion

In a similar vein to the above point, keep an eye out for any signs of rust or corrosion on the roof itself. This points to age and wear that has cause the protective layer over some types of metal, usually galvanized steel, to wear away, allowing rust to begin to form. These sections need to be replaced as soon as the rust begins to form, as if they are left too long the rust will quickly eat its way through the actual roofing panel and provide direct access for water to enter your home.
