Bitumen roofing sheets are a great lightweight and durable choice of sheet for almost any outdoor roofing project. Our bitumen roofing sheets come in a variety of colours with a corrugated structure for extra strength. Bitumen is very durable, and unlike the other roofing sheet options can often look better as it weathers in the eyes of many. It can resist impacts fairly well, yet it is incredibly easy to cut to size. Bitumen is nearly always corrugated, which helps to resist impacts as well as easily shed water. MOQ 20ft Container. Supplied from Turkiye, India or China.
