Roof covering options and the differences that matter
First establish whether a given covering suits the roof at all, and only then compare its appearance and the cost of the whole solution. Check the pitch and the method of water drainage, because a material intended for a steep roof cannot always be used on a nearly flat slope. The minimum fall follows from the product documentation and may depend on longitudinal joints, skylights and other details. Also examine the loads, the type of support and the fire, thermal and acoustic requirements. Once these conditions are clear, the list of sensible coverings quickly narrows.
