A MANSARD roof is a style of roof characterized by two slopes on each side, with the lower slope being much steeper than the upper. It is named after the French architect Francois Mansart (1598-1666). An EAVES roof is a type of roof that has an overhang at the lower edge, which helps to protect the walls of the building from rain and snow. A hardtop roof is a type of roof that is made of a solid material, such as metal or plastic, rather than having individual tiles or shingles.
