Metal roofs are known for being durable and long-lasting, but even they can develop leaks over time.
If you’re in Florence, South Carolina, or nearby, you know how unpredictable the weather can be. When a leak happens, it’s important to act fast before it leads to more serious problems.
In this guide, we’ll show you how to find the leak, the common causes, and the best ways to fix them.
Before you can fix a leak, it’s helpful to know what might be causing it. Here are the most common reasons metal roofs start to leak:
Metal roofs are held down with screws, and sometimes these screws can work themselves loose or even fall out. When this happens, water can sneak through the gaps they leave behind.
Sealant is used to keep water out where the metal panels meet or where the roof connects to other parts of your home, like chimneys or vents. Over time, the sealant can dry out or crack, allowing water to seep in.
Even though metal roofs resist rust, moisture and salt in the air (especially near the coast) can cause the metal to corrode over time. When rust eats away at the metal, it can create holes where water can get through.
If your roof isn’t installed correctly, there might be gaps between the panels or other issues that can lead to leaks. This is why it’s important to choose experienced metal roofing contractors when installing a metal roof.
Leaves, twigs, and other debris can collect on your roof, especially in the valleys where panels meet. This debris can trap moisture against the metal, leading to rust and leaks.
Now that you know what can cause a leak, let’s talk about how to find it. Here’s a step-by-step guide you can follow:
Once you’ve found the leak, you’ll want to fix it as soon as possible. Here are some simple solutions:
If loose or missing screws are the problem, tightening them might be all it takes to stop the leak. If any screws are rusted or broken, replace them with new ones designed for metal roofs.
For leaks caused by cracked or worn-out sealant, you’ll need to remove the old sealant and apply a new layer. Make sure you use a sealant that’s made for metal roofs, as it will hold up better in the weather.
If rust is the issue, clean the rusted area and apply a rust-inhibiting primer. If the rust is extensive, you might need to replace the affected panel to stop the leak.
If the leak is due to poor installation, it’s a good idea to call a professional roofer. They can realign the panels or fix any gaps to ensure your roof is properly sealed.
Prevent future leaks by keeping up with regular roof maintenance. Check for loose screws, worn-out sealant, and debris buildup every few months, especially after storms.
If you’ve tried these steps and still can’t find or fix the leak, it might be time to call in a professional.
