"Gable", "hip", "gambrel", "shed" and "mansard" roofs are the main types of pitched roofs. The type of roof on a building helps identify the building style. For example, an American Arts and Crafts style versus a Cape Cod style. Roofs are often covered in asphalt or wood shingles. But they can also be covered in metal, slate, or clay tiles. It can be dangerous to walk on a pitched roof. Some pitched roofs have parts that stick out for windows. These are called dormers. The edges of pitched roofs are called 'eaves'. Often there are gutters and leaders at the eaves, which take away water from the roof.
