Metal roofing sheets have ridges on the top. They should be cut with the ridges upside down. You can use a calculator to estimate the number of sheets you will need. Once you know the size of the sheet, you can fit it to the roof. For example, a 21-foot-by-10-foot roof is 210 square feet (20 square meters) in area. Therefore, you will need approximately twelve sheets.
