Thinking about purchasing a metal roof for your home? That could be a wise decision. A metal roof can enhance your home's aesthetics and add valuable protection against the elements. It's also durable, as metal roofs can last decades. In fact, your new metal roof may be the last roof you ever need.
Of course, a roof is only as strong as its installation. The installation process is important with any roof, but it's especially important with metal roofs because of the seams between the sheets of metal. If the seams aren't in alignment or the screws are too tight or too loose, you could develop leaks, corrosion, or a wide range of other issues. Below are a few possible issues that could arise and require metal roof repair if you choose the wrong roofer to install your metal roof:
Leaks. The most obvious potential issue with any roof is leaking. Of course, there many reasons why a roof may leak that have nothing to do with installation. Some causes, like extreme weather, may be completely unavoidable.
However, a good installation team can minimize the risk of leaks developing in your metal roof. Even the smallest error can lead to leaks. For instance, a screw that is too loose or off-center could be a spring hole for a leak. Unaligned seams are potential leak spots. If the roofer fails to apply the correct amount of sealant, you could have a leak on your hands. Some leaks may be inevitable, but the right installer could reduce your risk.
Corrosion. One of the main benefits of a metal roof is that it protects against corrosion. That's because most metal roofs are treated with sealants and protectants. However, corrosion could occur at an accelerated rate if the wrong metals are combined with each other. For example, some of the most commonly used roofing metals don't interact well with brick, copper, iron, and other common construction materials. Your roofing installer and can analyze your home and determine how your new roof may work with the other materials in your home's construction.
Oil canning. Oil canning is a generic term for the wavy appearance that can sometimes develop in sheets of metal. It can be caused by many things, including natural elements. In some cases, it simply can't be helped. However, your roofer can take steps to minimize the chances of the oil can waviness. For instance, they can use thicker metal or they can use a matte finish to reduce the visibility of the waves. An experienced metal roofing service will know how to diminish the impact of oil canning on your new roof.
