Make Sure Your Sheets Are Facing The Right Way Up
Place your metal sheeting on your workbench with the underside facing up. You’ll need to make sure that your workbench is even, as this will give you a solid base on which to cut your metal siding.
Make sure the flat side is facing you, as the underneath is much easier to cut than the top.
The top side of each of these ridges protrudes up in the air, which makes them a lot more tricky to cut. You’ll want to make sure that these ridges are facing down instead of up. Remember a little tip: make that the ridges look like valleys instead of hills.
Work Out How Many Sheets You Need
Now you’ll need to work out how many sheets that you’ll need to cover your entire roof. Do this by measuring the entire surface area of your roof.
Measure the length and the width of your roof and then you can work out the entire surface area using these measurements.
You can then use this measurement to determine how much metal sheeting that you’ll need. You’ll also need to know how your metal sheeting will fit together, so you’ll need to have an accurate measurement of the overlap.
A good method of finding out exactly how many sheets that you’ll need is by dividing up the surface area of your roof by the number of sheets that you have. This way you can determine exactly how many sheets that you’ll need for the job.
You can also go online and use a roofing calculator that will help you to determine how many roofing sheets that you’ll need.
Because let’s face it, nobody likes doing maths half the time! You can then fit your sheets together and cut them based on the final measurements.
Measure The Edges
You’ll need to measure the sides in order to make marks on where you’ll need to start cutting.
You can use a tape measure to determine the point where you start cutting and to form a guide that will help you to stay in line.
Make sure that you are measuring your roof exactly, as any gaps in between will likely lead to leakages in your roof at a later date.
We would recommend that you do your roof calculations more than once in case you’ve made a mistake.
