The indication of an experienced carpenter is the ability to lay out rafters and frame all types of roofs. On most job sites, the boss lays out the different rafters and the workers make duplicates of them. Those carpenters that want to be in supervisory positions must know how to frame various kinds

There are seven types of roofs carpenters need to know how to frame. They are: gable roofs, shed roofs, hip roofs, intersecting roofs, gambrel roofs, mansard roofs and butterfly roofs. A common roof style is the gable roof, which is where two sloping surfaces meet at the top. They form triangular shapes at each end of the building called gables. The shed roof slopes in only one direction. Also called a lean – to, the shed roof has been exclusively used on contemporary homes. The hip roof slopes upward from all walls of the building. This style is used when the same overhang is desired on all sides of the building. An intersecting roof is needed on a house when two wings intersect. Since two roofs are intersecting, valleys are formed which require several types of rafters. The gambrel roof is a variation of the gable roof because it has two slopes on each side instead of one. The lower slope is mush steeper than the upper slope; therefore framing it is like framing two separate gables. A mansard roof is a different type of hip roof; it has two slopes on each of the four sides. The last roof type is the butterfly roof, which is an inverted gable roof. It resembles two shed roofs with their low ends placed against each other. (Bliss, 1997)
