Exposed fastener metal roofing is a type of roof where screws or nails used to secure the panels are visible on the surface. These fasteners typically have rubber washers to create a seal, preventing water intrusion. Over time, however, exposure to weather elements can cause the washers to deteriorate, or the fasteners to loosen, leading to leaks. This is a common concern with this roofing style because the points of penetration through the metal are vulnerable spots. A simple way to check your roof is to look closely for rust on the screws, cracked or missing washers, or any signs of water stains inside your home underneath the roof’s coverage. If you notice movement of panels or loose fasteners, it’s best to address these ASAP to avoid bigger issues like water damage or structural decay. Carefully walking on the roof can help with the inspection, but safety should come first—use proper footwear and avoid walking on steep slopes.
When it comes to warranty options for exposed fastener metal roofs, it’s important to note that most warranties cover manufacturing defects and sometimes limited performance for a set number of years. However, warranties often exclude damage caused by improper installation, weather events, or lack of maintenance like failing to tighten loose fasteners. If you are considering a new roof or repairs, ask your roofer if the fasteners and washers they use are covered under the manufacturer’s warranty, and whether they offer any additional workmanship guarantees. A good question to pose is: “How do you inspect and maintain fasteners to prevent leaks over time?” and “What warranties come with the fasteners specifically, including coverage for washer deterioration?” These questions ensure you understand the longevity and responsibilities of your roof system. Calling a licensed pro for a thorough inspection can save both money and headaches down the line.
