Building roof trusses – The lattice is in a variety of shapes and sizes, depending on the type of roof structure. Truss framed for the simple gable, gambrel, cathedral ceiling or attic. Residential roof truss can measure anywhere from 16 feet to 50 feet long and can be as high as 6 feet to 16 feet. The size of the truss depends on the length and height, or pitch and tension, plus any cantilever if applicable. Because of new technology and ease of production and use of trusses, most new houses built with trusses.
Building roof trusses locate a large open area outside. Roof truss is constructed lying down. Set up a table saw. Most of the roof truss 2-by-four hours will have to be cut to size. When measuring and marking wood, cut everything at once, so it is ready for construction. Place a 24-foot piece of 2-by-four hours as your bottom chord trusses. Make a triangle of two 18-foot pieces of 2-by-4 timber which connects the upper top and bottom overhang the edges of the base flange about 6 inches.
