When choosing a corrugated board for a roof, it is important to take into account the size of the sheet and its price. The sizes of the sheets can be standard or cut to order, which minimizes the amount of waste. For the roof, corrugated board with a wave height of 20-35 mm is most often used. The cost varies depending on the thickness of the metal, the polymer coating and the brand. When choosing corrugated board, pay attention to the price-quality ratio so that the roof will serve for many years.
