There are many reasons why designers, home-building contractors, and actual framers themselves find using stick-built roofs to be an attractive option. Not shown is the bottom chord or ceiling joist ( photo credit: © Leerobin | Dreamstime). This view of a roof under construction shows some of the main elements of a stick-built gable roof: rafters, ridge board, collar tie. This roofing member is a length of dimensional lumber that connects the rafters of a gable roof at the middle to top third of the rafter span to counteract the natural spreading forces of the rafters. This is a board that acts as the bottom chord of each rafter and forms the ceiling of the space below.Ĭollar tie. It is important that the ridge board is the same size as the rafter boards, although in some circumstances, a ridge beam – a more substantial length of lumber that can bear a structural load – might be used instead.Ĭeiling Joist. This is the board that creates the peak of the roof and is rarely a load-bearing structural member. These boards are fastened in two places: to the ridge board at the peak of the roof and at the top plate where they join the wall. Carpenters usually use 2x8s, 2x10s and 2x12s. They are usually wider than a classic piece of timber. Rafter Boards are what create the slope of the roof. Each piece of wood has to be cut to size and fastened together manually, along with a ridgeboard, to form a roof. How Do You Build with Rafters? Carpenters cut each rafter from dimensional lumber on the job site. The main complication comes with the intersecting gables of the intricate roof design ( Plan #198-1095). The overhead view clearly shows the rafters and the relative simplicity of the construction. This gable style roof is a good example of a stick-built roof structure.
