The roof is a very complex structure, which consists of individual elements. It allows you to withstand the main load of the snow cover or sharp gusts of wind thanks to well-fitted and rigidly connected nodes. The rafter system of a gable roof without a roof is very similar to the ribs that support the whole body, including all its air and heat-insulating layers. It is these functions that the rafters perform along with additional extensions, crossbars and puffs.
The rafter system of a
gable roof is used not only for private houses. It is erected in garages or sheds, using a wooden beam for this. Wood is easier to mount and interconnect. But you can use an alternative system. The design of the metal frame allows you to accelerate the construction of the house. When ordering such a rafter structure, you get ready-made blocks that need to be raised to the roof and assembled in place.
The roof truss system may or may not have a ridge run, here it all depends on its type and size. The hipped roof has four sides, each of which resembles an isosceles triangle. Converging peaks at a central point, they form a complex ridge node. The quality and reliability of the entire structure depends on how professionally it is performed.
The hip roof also has four slopes, but two of them resemble a trapezoid in shape. The rafters when erecting a roof on both sides fix the ridge run. To increase the area of the attic, the rafter system of the gable roof is slightly modified.
The mansard roof has an additional bend on each side, which allows you to expand the spans of the sides and get full rooms with ceiling heights of up to 2.5 m.
Although the roofs seem to perform one task, they should be approached individually. The order and sequence of work depends on the configuration of the house, on the type of roof itself. Sometimes there are buildings with a surprisingly complex structure, which accommodates almost the entire range of configurations. Here in the first place - elite buildings. There is a tent on the roof, and a hip roof, and somewhere on the side the rafter system of the gable roof is still attached. It is very difficult to carry out and combine all these elements, but if true experts undertake this, then the roof can become a work of art.
For self-construction, it is better to use simpler options, where there are not many complex nodes. After all, the roof truss system is only the first part of the work. This is followed by insulation, crate and flooring of the selected material for the roof. If a complex roof configuration is chosen, then it is necessary to carefully insulate all joints so that moisture does not penetrate inside.
Before you start building a roof yourself, evaluate your strength. Not always saving money gives the planned result. After all, the time and effort that you spend on this can be used to greater advantage.
