The design of the roof plays a significant role in the architectural attractiveness of the building and has an important practical function. Reliable and beautiful hip roof is often used as a roof option. A lot of attractive house projects, the photos of which you can see after reading the article, clearly show what the original design has a hip roof. It is characterized by the device of four slopes, at least two of them are triangular in shape. They are located at the ends of the building. The structure of the truss system is more complicated than that of a gable roof, but a hip roof can also be built with your own hands.
Gut-hipped roofs of the house
Drawing the hip roof
Execute a drawing of the hip Roofs with a detailed description of the length, section of elements and angle of inclination - this task is beyond the power of a beginner. The scheme should be constructed taking into account calculations using special formulas. It can be calculated, for example, with a construction calculator. Choosing the angle of slope for the slopes, focusing on the type of roofing and weather conditions, you can calculate the height of the ridge and other values. The shape and size of the truss structure also require a detailed calculation and description in the diagram. If you are in doubt that you will competently draw up a project yourself, it is better to contact the specialists.
The truss system
For construction, select dry, flat wood of coniferous species - larch, cedar, pine. Pre-material is treated with antiseptic.
Calculates the centerline and the location of the rafters
Before you make hip roof, you need to markup. Accuracy of marks will allow to avoid mistakes when mounting rafters. Initially, the centerline is calculated, then the location of the rafters. The location of the central rafter is marked at the point denoting half the thickness of the ridge. Marking the position of various types of rafters is best done not with a tape measure, but with a measuring rod. With its help, it is easy to note the location of the central intermediate rafter. One end of the rail is aligned with the intended line, and the other is directed along the line of the side wall.
Hip four-pointed roof If you present the markup in the form of a projection, it becomes clear that intermediate rafters with a wall form a square, and the angular rafter divides it diagonally into two rectangular squares. The length of the corner rafter allows you to calculate the Pythagorean theorem. A special table of coefficients allows you to calculate the size of the corner and intermediate rafters. To calculate, you need to measure the horizontal projection, find the angle corresponding to your angle of inclination of the slope and multiply the length by the factor. The length of the short rafters is calculated by multiplying the lay of the mower and the coefficient of intermediate rafters. All measurements are consistently performed at the four corners. On the marked points are guided, how to build as a truss system.
The rake for marking is made of plywood, 5 cm wide. It indicates the required dimensions.
Installation of the truss system
Additional elements of the truss system
Additional elements are used depending on the size of the spans and the design :
A sufficient overhang of the roof is ensured by the length of the rafter legs or with the help of nail boards "fillings". Rafter legs are fixed to the mauerlat in several ways: brackets, metal corners, nails. On the ridge, the rafters are connected using bevels and fastened with metal plates. After that, installation of the batten is performed.

Without having experience building a complex hip roof, you can watch a training video or consult a specialist.
