The famous Sudeikin roof structure has become a real architectural rarity today, however, to this day in Russia, you can find entire villages where most of the buildings have a roof of this effective and original design.
For reference
Sudeikin's roof construction technology was developed about 100 years ago. Today, interest in it is gradually reviving, as the benefits have not lost their relevance. But the owners of private houses rarely resort to such a construction technology, since it is rather problematic to build a structure of this form without professional help. And sometimes you don’t want to spend money at all.
Design
Sudaika's roof is a structure that has four gentle waves, and four triangular slopes adjoin their base, they are located with their tops down. 4 pediments are formed between the slopes. As a feature of this design is the absence of rafters in their usual sense. Functions of this systemthey perform bars that are interconnected, an octahedral dome is formed from them, which serves as the basis for the roof.
It is worth paying attention to the fact that the classical project of Sudeikin provides for the presence of a support pillar in the central part. However, practical implementation and calculations have shown that such a roof can be built without a central support, for this it is necessary to make the slope of the dome sharp, increasing the bearing capacity of the structures.
The judge's roof looks very impressive and stylish, but they build it only for those tasks that have the shape of a square. For a house with a rectangular wall perimeter, such a roof can be made by combining two or more main structures. But at the same time, you will have to make valleys, which the main project is deprived of. Among other things, it is necessary to correctly calculate such a roof, only in this way it will be possible to maintain proportions, eliminating the likelihood that the appearance of the structure will be damaged.
Why choose a Sudeikin roof
Sudeikin's roof is chosen for several reasons, among them is the possibility of using a large attic space, which is used during the operation of the building as a living space. The attic turns out to be well lit, which is provided by four windows located in the gables.
The thermal insulation of the dwelling is increased due to the presence of a small attic above the attic. There are no grooves and valleys, otherwise they become pockets that retain moisture and snow. Sudeikin's roof has a large slope, which guarantees the immediate removal of precipitation from the surface in a natural way. There is no need for drainage gutters, but in a classic roof they are located along the perimeter of the roof. Roofing material is consumed in less quantity than when building a gable roof of a house of the same area.
Selection of material for Sudeikin's roof before construction begins
A huge variety of materials did not touch Sudeikin's roof. The most suitable option are quick-cut materials such as shingles or corrugated board, as well as wood. You can also prefer a fine-mesh surface. However, the classic design is designed for iron coating.
Looking at the roofs of the houses, the photos of which are presented in the article, you may notice that modern and inexpensive, as well as such a very attractive material as tiles, is not used for the Sudeikin roof, for the reason that in the process of work you will encounter a lot of waste. It is formed due to the need to construct triangular-shaped elements.
Mounting Features
Laying roofing and insulation materials is almost the same as the technique of working on a conventional shed or double-slope roof. During construction, the triangular shapes of the roof components must be taken into account. At the first stage, 4 racks are installed at the corners of the building, each of them should have the same length. On the upper spikes of the racks it is necessarystrapping with the help of bars that will form a square.
The center of each wall must be determined, then 4 vertically oriented posts are installed in the center of each wall. The next step will be fixing the inclined bars that form the strapping of the gables of the building. Why they are strengthened to the top of the central pillars and to the corners of the strapping, which rises on the racks. The central post must be fixed, and its length must be greater than the height of the gables, everything will depend on the planned angle of the slope and the dimensions of the building.
Recommendations for work
If you are going to equip the octagonal dome of the Sudeikin roof, then the next step is to fix the bars that connect the rack in the center and those that are fixed in the central part of the wall of the house. These beams protrude outside the building by the width of the overhang.
The posts, which will be located in the central part of the wall, and the inclined bars of the gables must be connected with four horizontal bars, which form a square and strengthen the structure.
Settlements
Calculation of Sudeikin's roof 8x8 m can be carried out by you independently on the example of the fact that for a roof whose dimensions are 7x7 arshins, you will need 18.5 square fathoms of iron. Such calculations are given in the old edition of the book. An arshin is equal to 0.7 m, while one square sazhen is equivalent to 4.5 m2. For example, note thatfor a gable roof of the same area, 21.3 square fathoms of iron will be needed.
As for the usable area of the attic space, at the Sudeikin roof this parameter will be 9.8 square fathoms, while at the gable roof the attic space will be limited to 4.07 square fathoms. Looking through the roofs of the houses, the photos of which are presented in the article, you can make a choice in the direction of one or another design. But in favor of the Sudeikin system, it can be noted that the remaining roofs will have even less usable under-roof space.
Possible problems during construction
How a Sudeikin roof for a rectangular house can be arranged was mentioned above. However, if you decide to do the construction yourself, you should remember that you may encounter some problems. They are expressed in the fact that most of the design details are not mass-produced, for this reason you have to reckon with a large amount of work that you will have to do manually.
Among other things, all the supporting elements of the system require professional calculations and design, this can not always be done by an ordinary home master. When considering Sudeikin's roof projects, you may also encounter such complexity as a very limited choice of covering materials. Such a design is not in demand today also because it was simply forgotten about. Today, lovers and craftsmen of original solutions are reviving interest in this beautiful non-standard roof, but to find specialists for constructioncan be quite difficult.
