| It is common in roofs of any type of combustible construction, supported by either rafters or trusses, that the part of the roof that extends http://avtokran.webuda.com beyond the wall is supported by the "tail," the cantilevered part of the rafter or truss (photo 2). These tails are usually (but not always) part of the rafter or truss extending beyond its bearing point. Sometimes the tail will be exposed when the building is finished; is also decorative; and is a separate piece of lumber connected to the end of the rafter or truss at its bearing point by nails, screws, or other fasteners.
It is also common in roofs supported by either rafters or trusses that the part of the roof that extends beyond the gable wall (photo 3) is supported by short, cantilevered pieces of lumber that bridge the http://renstroi.comuf.com top of the gable wall and are connected to the nearest rafter or truss (photos 2 and 3). These short cantilevers depend for stability on their connections to the top of wall and their connections to the nearby truss or rafter.
