How to cut sheet metal roofing can be a little tricky for most homeowners. It’s widely known as an affordable roofing option but also one that is aesthetically pleasing. But if you’re planning on performing the installation process yourself, you still have to know how to cut a sheet metal roof. Here’s how:
The first step is to identify where you will cut metal roofing as well as how much material will be required. It will be best if you use a stud finder to find the studs. Then you need to align them on top of the roof and start hammering them in with the appropriate screws. Continue doing this until you get to the ridge. Then you need to take the sheet metal roofing and cut it with saws, a band saw or a nail gun.
The second step is to set up your cutting area by ensuring all your fixtures are at the right height and distance. A good practice is to line up the circular saw and your nail gun in such a way that you will not have to move from the previous spot when you are cutting. You can choose any angle grinder that you prefer and start at 45 degrees to the right or left depending on the diameter of your rod. Use the same method when cutting the metal as you would when cutting tin cans. Continue this process until the entire surface is cut.
The third step is to use a straight cut to cut the rest of the metal roof. It is important not to cut too deep into the metal roof as you do not want any water seeping in. Straight cuts make it easy for you to complete the task in a short period of time.
After you have completed this process you will be ready to start cutting the tin snips. Electric shears are often used when cutting metal roofs but a pair of tin snips work just as well. Make sure that you have a length of tin snip in hand so that you can start the process immediately after you unplug the electric shears. If you start the job after the shears are already in use, you will risk getting your hands and fingers hurt.
Once you are done with this step of how to cut sheet metal roofs, you can proceed to the next one which is the top portion of the roof. Always remember to work from the bottom towards the top to avoid cutting any water pipes or ductwork. You may want to start trimming the metal sheets before you get to the top or else the top will be covered with a thick layer of water and this may cause some damage to the roof.
