![]() ![]() The carpenter working in the middle needs to allow the plumb cuts to rest together and support the load. Now, go to the opposite side of the house and do the same thing. The carpenter in the middle must help you hold the top in its desired location. Now you can start by fixing one rafter on the top of the wall right next to the joist of the ceiling. While 2 of the carpenters needs to be located in the middle of the building close to the area where the board ends, the third carpenter needs to hand over the commons to the carpenters in the middle. Moreover, you need 6 common rafters properly cut and located close to their final destination. You will need a minimum of 3 carpenters to set this board on the roof. Once you have set up the ridge board you will get to know the location of the hips. The first thing you need to do is set up the ridge board. One can choose to leave the ceiling joist ends out till the hip rafters are located. Once you have laid out the common rafters, you would need to place the ceiling joists alongside the area where the rafters would be placed. Now that you know the run of the common rafters you need to measure the outside corners of the house where the hips are to be placed. This would be about 5 feet and 11 ¼ inches run of the common rafter. Now deduct the thickness of ridge board divided by 2. Make use of a construction master calculator and enter 12 feet. Therefore, we will be using 12’ rafters in this case. So, we have to start by measuring the exact width of the building so as to find the run of the common rafter. During this stage we are going to concern ourselves not with the pitch of the roof, but rather with the run of the common rafters. ![]() This would enable the builder to place the joists of the ceiling by the side of the hip jack and common rafters.įor instance, let us suppose we have to frame a hip roof for a building measuring 12’x28’. This step involves finding the run of a common rafter. The initial step in framing this roof is not much different from that of the gabled roof. It not only leads to a chicer look, but also makes the building more resistant to wind. Framing the hip roof can be more expensive than framing a gabled roof since you need to pay for the labor cost for framing the hips. Similar to a gabled roof, a hip roof is also made out of common rafters along with jack rafters and hip rafters. Hip roof truss framing isn’t a very easy job, but if you have the right tools and proper guidance framing a hip roof can be a simple task. Now that we know the names of all the various kinds of hip roof trusses let us move on to the more important aspect of our article, viz. Half truss: this is a full truss which has been cut off from the apex. The top chord comes with 2 different pitches and the lower pitch covers the patio or balcony.īowstring truss: They are mainly used for commercial building where the top chords are designed so as to make way for a curved roof.Ĭantilever truss: This could be any other truss provided that the support point is located within the span and not at the heel.Ĭut off truss: They can be any variety of trusses, but they don’t come with a heel. They come with an equal pitch ceiling on either side of the apex.īell truss: This truss is most commonly seen on Federation houses. Scissor Truss: This is a modified truss created to suit a ceiling with slopes. Just like the hip truss, it has an extended top chord which meets the hip truss.Ĭreeper truss: this is the truss which meets the hip truss without any elongation of the top chord. Jack truss: The jack truss runs right into the hip truss. Though not much different from the half truss, the hip truss comes with an elongated top chord which finishes as the hip top. Hip truss: Hip truss is responsible for forming the hip line on the roof. Therefore, this is the strongest of the truncated trusses since it has to take all the loads. It carries the weight of the outer hip trusses along with that of the creeper trusses, jack and hip. Truncated girder truss: The main truss which lies on the hip end is known as the truncated girder truss. Truncated Standard Truss: this has the shape of a standard truss, but its top portion is cut off so that the slope fits on the top of the hip end. In order to fully comprehend the hip roof truss system we have to take a closer look at the different kinds of trusses used in the hip roof. Though in present days this kind of roof is mostly seen in cottages and bungalows, the hip roof style is widely being used in a vast range of architectural structures. This kind of roof doesn’t have any vertical slides or gables. Hip roofs require an extremely complicated system of trusses and rafters. A hip truss roof is a kind of roof whose slides come with a gentle slope and it tends to slope down toward the walls. ![]()
