When you need extra storage and work space on your property, installing a pole barn is an easy, durable, and cost-effective way to cater to these needs. While these buildings can last for many years, they require regular maintenance, particularly the metal roof. Much like the home, this roof has a finite life span, and if you notice the issues below, you may need to replace it.

When Should You Update a Pole Barn's Metal Roof?

1. Widespread Rust

Manufacturers of metal roofs apply a specialized coating that resists moisture to the panels. Over time, this protective layer can deteriorate after long-term exposure to water and sunlight, allowing moisture to contact the metal directly, eventually rusting the roof.

Typically, you will first notice this issue around the seams, such as near the vents and along the flashing. However, rust can form anywhere, and you may not realize it until water starts leaking into the barn. While roofing contractors can repair minor issues, if you see rust forming across the structure, you likely need to replace the roof.

2. Loose Panels

Over time, wind and debris can impact the pole barn, causing the metal roofing panels to separate. This allows moisture, debris and pests to enter the building, compromising the safety of yourself and your equipment. Sometimes, you can tighten the fasteners and gaskets on the panels to keep them from separating further. However, if these components are stripped or missing, the best solution is to replace the roof. This will prevent further issues from developing, protecting your building from damage.

3. Condensation

Whenever you notice water forming inside the barn, you should have a contractor inspect the roof. This can happen when moist, outside air enters the structure and cannot exit, causing the water vapor to condense on the cold roof. When the water droplets form, they can fall inside and ruin electric equipment and contribute to mold growth, which can cause respiratory issues for anyone inside. While you can minimize this by opening vents and allowing air to circulate, when the issue affects the entire structure, you may need to replace the roof.
