How to Cut Sheet Metal Roofing Using a Circle Grinder

Metal roofing is generally an inexpensive option that provides excellent protection against both the elements and the adverse conditions brought about by climate change. However, it isn’t just a durable roof solution; it is also one that is aesthetically pleasing. However, if you intend on undertaking the installation process yourself, you should know how to cut sheet metal roofing properly. Doing so will ensure that you not only get a roof that looks great, but one which is safe to live with. Here are some important pointers that will help you achieve this.

One of the first considerations to make when learning how to cut metal roofing is the type of material that you intend to use for the roof. The most common, of course, is aluminum, which is quite durable and comes in a variety of colors. However, metal roofs may also be made from copper, tin, zinc and even wood – although these will be more difficult to work with.

When learning how to cut metal roofing, the first step is to ensure that you have the proper tools. This includes a diamond-carbide skill saw, a hammer, chisel and tape measure. While these tools aren’t absolutely necessary, some people prefer to buy them in order to take advantage of deals and special discounts on them, especially when buying online. If you do take the time to learn how to make use of these tools, however, they will nevertheless be of great help in making the straight cuts you need.

Another important consideration is the kind of metal that you’re dealing with. For instance, aluminum sheets require diamond-carbide skill saws in order to make straight cuts. Steel, on the other hand, can be cut using a hammer, a skill saw and tape measure. Wood, on the other hand, can only be cut with a chisel, a hammer or tape measure.

It’s also important to note that the right technique is imperative for the best results when cutting metal roofs. You can start by lining up your circular saw, preferably at an angle that’s halfway between your shoulder and the roof. Start with a horizontal stroke, making sure to keep the blade at a right angle to the circular saw’s axis. When you’re done, move the circular saw’s blade one diagonal step to the left.

Now, slice along the line you’ve just drawn, making sure to keep the width of the cut at the same level as the width of the blade. Stop once you reach the center of the roof, but before you push the blade too far away from the tin object. Use the tin tool to hold the blade stationary while you work the saw back and forth. Your goal should be to get the depth of the cut at about half an inch, which is where tin will bend when cut.
