Metal roofing offers a lot of advantages over other types of roofing materials. It's attractive, very durable, impervious to water and insect damage, and fire resistant. However, metal roofing isn't indestructible. It is likely that your metal roofing will need a few repairs over the course of its long lifespan.
Common metal roofing repairs
1. Loose nails and leaky seams. While metal roofing panels are waterproof, the seams are vulnerable to leaks. This is generally caused by nails becoming loose either by careless installation or years of exposure to harsh weather. This is a relatively easy thing for a professional roofing team to correct.
2. Rust. While metal roofing panels are galvanized to prevent rust and corrosion, this coating can be compromised by things like someone walking on the roof or a tree branch brushing repeatedly against the panel surface. Mild rust spots can be removed with a wire brush by a professional roofing team. Larger rusted areas will likely have weakened the panel and will need to be replaced.
3. Loose flashing. The area where the roof meets apertures like vents and chimneys are vulnerable spots on any type of roofing, including metal roofs. When the metal pieces that seal these openings bend even a little bit, they can send water cascading into the interior of your home. Flashing generally has a shorter lifespan than metal roofing panels and will need to be replaced periodically.
4. Dents and cracks. While a well-installed metal roof can last for decades, this type of roofing is subject to dents and holes when things fall on it, such as tree limbs, poles, and large hail stones. Depending the extent of the damage, this may make it necessary to replace one or more metal roof panels.
5. Pooling water. Water collecting on your metal roof can cause it to rust over time. This situation is generally a result of poor insulation or dents caused by falling debris. If caught early, this situation is easy to repair and will prevent the panel from failing and causing water to enter your home.
While metal roofing is very durable, it may need a few repairs over the course of its life, things like replacing panels, fixing loose nails and brushing out rusted spots. Having your metal roof inspected periodically by a professional roofing contractor, like those from Acoma Roofing, Inc., can help to catch potentially expensive repairs before they grow into large roof problems.
