Common Issues with Metal Roofing

Metal roofing is enjoying a meteoric rise in popularity, particularly here in the south. Prefabricated metal roofing has a specific aesthetic appeal, and it’s an ideal choice for houses built (or novated) in the “modern farmhouse” style.Compared to traditional asphalt shingled roofing, metal roofs are significantly more expensive. A lot of people think it’s worth it, however, for the longer lifespan and reduced maintenance that come part-and-parcel with these kinds of roofs. Metal roofs are also much lighter, fire resistant, eco-friendly, and relatively quick to install. Here at Accent Roofing, we work with all kinds of Georgia roofs. In case you’re considering metal, here are a few of the most common issues we see with metal roofs. Denting Denting can be a problem for metal roofs. We always advise our customers to strongly consider “dent-proof” metals, and also to remember that some metals – like steel – are stronger than others – like aluminum. Metal roofs can be dented in a variety of ways, especially during one of our strong hail storms or when being walked on by an inexperienced roofer. In most cases, dents are purely aesthetic problems but in situations where the dent is particularly deep, an issue with water runoff may develop. Oil Canning Also known as “stress wrinkling” or “elastic buckling,” oil canning is when the flat parts of a metal roof begin to appear wavy and even buckle in places. It is very common and is typically a byproduct of the actual metal itself, not (necessarily) the installation process. Once metal roofs begin to oil can, the affected panels must be replaced to solve the issue. Ways to prevent canning include using a thicker metal sheeting, choosing a “stretched” metal, and having the roof installed over a totally flat decking. Leaking Leaks are the number one problem for almost any roof, and metal is no exception. Metal roofs tend to leak most at their fastener points but proper installation can help. A number of factors can make leaks more likely on a metal roof including driving rain, heavy wind, structural damage, and even back-to-back ice events. When installing a metal roof the flashing, seams, and fasteners are the most important areas to pay attention to for preventing leaks. Scratching Almost all modern metal roofs have some type of coating. In many cases, the coating also doubles as a paint,…

How to Prepare to Have Your Roof Replaced

Your roof is one of the most important – and most expensive! – components of your home. It’s totally understandable that homeowners would be interested in extending the lifespan of their roof as long as possible. Replacing a roof is always a big investment. So, how often does your roof really need to be replaced? The experts at Accent Roofing, one of Atlanta’s best roofing companies, weigh in. Roofing Materials Matter The number one factor that will determine exactly how long your roof will last is what it’s made of. Certain roofing materials are more durable than others and more likely to hold up in conditions like rain, hail, or strong winds. Here’s a general guide to how long several common roofing materials can be expected to last: Composition Shingles: 12-22 years Asphalt Shingles: 15-30 years Wooden (Cedar) Shingles: 15-25 years Tile Shingles: 40-50 years Metal Roofs: 50-75 years Why the Discrepancy? Because different materials require different levels of maintenance. Composition shingles, for example, are low-cost but also on the low-end of the durability spectrum, depending on the style and brand. A very well-maintained composition shingle roof can last more than two decades! A composition roof that’s never cleaned, inspected, or repaired might only last 12-15 years. Remember that roof maintenance is compounding. You can’t ignore your roof for ten years then expect to make up for lost time with one big repair job. The more regularly you have your roof inspected the earlier on you’ll catch little issues that can turn into big ones: missing shingles, loose flashing, leaking underlayment, and more. How Can You Tell When It’s Time to Replace Your Roof? There are a few tell-tale signs it might be getting close to time to replace your roof. Sagging, especially when obvious from the ground, is a key indicator that the roof’s structural integrity has been compromised. A significant number of missing shingles could also mean it will be less expensive to have your roof replaced than repaired. The only way to know for sure? Have your roof inspected by a professional roofing company! Some roofing issues, even serious ones, can only be determined through a thorough and comprehensive inspection. Having a roofer walk your roof, use tools to measure the moisture levels in your attic, and test the veracity of the materials used in its construction is the only way to really know its condition. How Long Does Roofing Replacement…
