They are used in many roofing applications such as Timber sheds, outbuildings, barbeque shelters, lean-tos, log stores and more. How many bitumen sheets will I need? With a simple calculation, you can work out how many sheets you need for your Corrapol-BT Bitumen Corrugated Roof. The coverage width of a Corrapol-BT Roof Sheet is 855mm allowing for one corrugation overlap or 760mm if you are allowing for two corrugation overlaps. For example, if you had a roof that was 5 metres wide by 2 metres deep/long you would simply divide the width of your roof by the coverage width of a sheet. 5000mm ÷ 855mm = 5.85 Next, round up the number to ensure full coverage, meaning in this example you would require six Corrapol-BT Sheets across the width of your roof. Next, simply divide the length/projection of your roof up to work out how many 1 or 2m sheets you will need in each run. Still unsure how many bitumen roof sheets you need?

Are Bitumen Roof Sheets made longer than 2 metres? No unfortunately due to the manufacturing process, all bitumen roofing sheets are only available up to 2 metres long. For most applications, you can simply overlap the sheets to achieve greater lengths. A unique benefit of the Corrapol BT and Awnapol Premium Bitumen Corrugated sheets is that they are available in 1 metre lengths which helps to reduce wastage when overlapping to longer lengths. If you are looking for a longer sheet it is worth considering the Corramet corrugated roof sheets which are available up to 4 metres long. Although these 4 and 3 metre corrugated sheets have a small cost premium they are more robust and last over double the life of bitumen sheets. What's more, Corramet Sheets, come with fixings included.
