The eaves are dripping tiles, and the top is roof tiles. Ridge tile is a tile on the roof, which can be understood as a tile that can drain water to both sides in terms of adaptability. To be precise, ridge tile is a trough tile that covers the roof and overlaps with the tiles on the sloping roofs on both sides of the roof. Usually it can be made into herringbone, saddle shape and arc shape, and it can be used with clay tiles, glazed tiles, plastic tiles, asbestos cement tiles and other types of roofs.
