The shape of the roof and the execution of the rafter system depend on the configuration of the house, the selected roofing, as well as on which materials were used in the construction of the foundation and bearing walls. Since the main function of the roof is the distribution of total house loads and its protection, the design of the rafter systems is carried out taking into account all the strength of all kinds of factors affecting its strength.
Gable roof is the most traditional option for arranging in residential buildings up to three floors of roof. This design is given preference not only because of the advantages inherent in the inclined form of the rafters, but also because the installation of the rafter system of the gable roof is simple and ease, compared to other options. To calculate, design and install such a rafter system, even unprofessional people, if, of course, will strictly follow all the fundamental moments and comply with the requirements.
Gable roofs consist of two planes that have a rectangular shape. The upper part of the house from the end is a triangle. Mauerlatians and rafters (rafter legs) are the main elements of such roofs. In order to be distributed evenly along the rafter system and walls of the loads, the system of struts, crossbars and racks is used. With their help, you can create a durable and hard design, which at the same time remains simple and easy. A sparse or continuous crate is installed on the rafters on top, to which the roof of metal, bitumen coating or tiles will then be attached.
To reduce and distribute loads, a hanging or layered rafter system can be used. In both cases, rafter legs laid along the slopes remain the main figure of the entire system.
