Common Causes Of Metal Roof Leaks

Metal roofs are one of the most popular roofing materials among roofers and homeowners. This is because the roofing materials have a variety of styles, ranging from traditional silver to modern blues and red.

Although metal roofs offer homeowners longevity and durability, they are still susceptible to leaks. Here are some common reasons metal roofs leak and how you can’t prevent them.

1. Improper Installation Techniques

Unluckily, the number one reason metal roofs won’t last up o their lifespan is that they need to be correctly installed. The installation process of metal roofs differs from regular asphalt shingles, and almost every roofing contractor is well-experienced in installing them. So before you hire any roofing contractor, do your research and ensure that they are experienced in metal roof installation.

2. Roof Rust

Rust on your metal roof doesn’t necessarily mean that your roof is leaking, but if ignored, the rust can start to peel the coating on your metal roof, leading to holes or scaling. Once there are holes in your metal roof, water can come in, leading to major structural damage. Once you see that your roof has rust, lay over the area a rust inhibitor. This will stop the rust from spreading. Keep in mind that this is only a temporary fix; you should still call a roofer to inspect the roof and proffer a solution,

3. Failing Flashings

Flashings are a vital component of a roof, metal roofs inclusive. Flashing is a sealant for places in your roofing material that are penetrated, like a vent pipe or chimney; the flashing is a barrier against water seepage. Because flashing doesn’t have a lifespan as long as your metal roof, they’re bound to fail faster and would need to be replaced every 10 to 15 years. Performing routine maintenance makes it easy to prevent a roof leak through flashing.

4. Separated Seams

Many roofs are protected with sealants; sealants are applied over the seams to prevent water penetration. However, those sealants usually last only a short time because the roof shifts. That is why having regular roof inspections is important; it helps you know the state of every component of your roofing system.


Some of these things are bound to happen as we can’t always be in control, but we can ensure that they don’t worsen. You must get your roof fixed once you see signs of leakage. Otherwise, you’d be dealing with more serious issues in the future.
