Next, divide this length by the coverage width of a single roof sheet, which is typically 0.760 metres. This division will yield a decimal number, and to determine the exact number of sheets required, round up this figure to the nearest whole number. For example, if your roof is 6.0 metres long, the calculation would be 6.0 metres divided by 0.760 metres, resulting in 7.89 sheets. Rounding up, you would need 8 roof sheets to adequately cover a 6.0-meter-long roof. This calculation ensures you have the right quantity of roofing materials for your project.
