Learning how to cut tin roofing is simple if you follow a few guidelines. You will first need a good quality roofing tar paper to trace around your house and the boundaries of your roof. This helps to ensure the distance between the panels of the tin roofing will be consistent. It is better to start trimming the tin roof from the centre of your home and work outward. You can create a pattern on the first panel to give a rough idea of how the final trim of your tin roof will look.
The next step in how to cut tin roof properly is to mark the ridge line. Using a piece of string or a pencil, draw a line around the perimeter of the area you want to cover. Do this for the ridge and every other panel. You can then use a straight edge to mark the ridge line of each individual rafter. Trim the metal roof carefully following the string line using a racking tool.
Learning how to cut tin roofing should involve the removal of any existing shingles. If you are planning to use nails in the trim, then it is best to do so from the inside of the rafters. Take care not to cut metal roofing at an angle as this can lead to gaps. Instead, cut vertical and horizontal strips so that you can replace them easily in the future.
Once the strips have been removed, you can begin to learn how to cut metal sheets. To do this, start by using a circular saw. Cut along the metal edges, being careful to avoid cutting through the sheet metal. When making circular cuts, it is better to make the cuts parallel to each other.
Next, continue this process by removing the caps from the cans. These are often stuck on top of the tin can, impeding the proper formation of a clean seam. Once the caps are removed, you will be left with two parallel strips of metal. The next step in learning how to cut tin tiles is to remove these two strips of metal and create a beautiful faux tin tiles pattern.
This process requires a lot of patience and diligence. Start with a straight cut at the beginning so that you can get used to making curved cuts. Try cutting a different size pattern each time until you have mastered the straight cuts. If you are a perfectionist, then you may want to make sure your seams are perfectly even before putting the metal back together. Keep practicing and learning how to cut tin roofing until you are satisfied with your work.
