Few even professional builders and architects, not to mention the townsfolk, know what a Sudeikin roof is. Although this invention is no less than a century old, it was quite popular in pre-revolutionary Russia. What is so special about the roof of its owner, and how its design differs from others - later in the article.
In 1914, the architect Grigory Sudeikin published his book "Album of projects of winter dachas, huts, mansions." It contained roofs of a special design calculated by him for various buildings.
At that time, almost all the forms being erected now were already known. do-it-yourself roofing roofs, nevertheless, among specialists, the publication caused a stir. It was really something fundamentally new.
Advice! In the "canonical" roof of Sudeikin, there is a supporting pillar in the center.By experience and calculations, the builders proved that you can do without it. If it violates the attic space, the bearing capacity of other structures should be increased, and the upper part of the dome should be raised at a sharper angle.
The design does not have rafters in the classical sense of the word. The beams here make up an octahedral dome tied in a special way, on which the roof is attached, consisting of the same number of triangles.
At the same time, the book provided calculations regarding the economic and structural feasibility of such a solution. The author compared the consumption of roofing materials for various forms of roofing, and also estimated the space that the residents of the second floor can use.
The numbers turned out to be:
| Consumption of roofing iron with a roof size of 7x7 arshins | Useful area of the under-roof space when raising the roof of the 2nd floor by 6 arshins | ||
| At the roof of the feature Sudeikin | 18.50 sq. sazhens | At the roof of the feature Sudeikin | 9.80 sq. sazhens |
| With a gable roof | 21.29 sq. sazhens. | With a gable roof | 4.07 sq. sazhens |
| With mansard roof | 23.25 sq. sazhens. | With mansard roof | 5.95 sq. sazhens. |
| With hipped roof | 21.30 sq. sazhens | With hipped roof | 1.69 sq. sazhens |
| With gable roof | 19.13 sq. sazhens. | With gable roof | 6.46 sq. sazhens. |
In appearance, the difference is small, but the used measures of length should be taken into account: arshin -0.7 m, sq. sazhen - 4, 55 square meters. That is, even the gable roof lost in terms of material consumption by more than 2 square meters. m, and in terms of usable area - for all 15!
However, despite such useful qualities, they forgot about the roof. It is not very technologically advanced, many parts are not subject to serial production, and are made by hand.Although the ideas were once used by Soviet architects.
In general, until recently, it was rare to see such a roof in holiday villages. . However, enthusiasts raised the archives and tried to revive the idea.
Although for mass construction - the same glued beam houses, for example, it is not used, but some construction companies have already included houses with a Sudeikin roof in their catalogs.
Yes, and "homemade" do not sit idly by, check the roof for viability, and assure that the roof works perfectly.
But still such a design did not become mass. What's stopping you? This:
- The need for careful calculation of both load-bearing structures and elements of roofing material
- Inability to use some popular coatings - for example, metal tiles, due to high unproductive consumption
- The limitation of the use of this form is only square in terms of houses
- Unusual appearance
- Ignorance of the very existence of this roof
Important information! For roofs with a similar dome, it is desirable to use fine-mesh materials - ceramic or bituminous tiles, or rolled. Non-directional sheet ones are also suitable - like galvanized iron. The metal tile is laid strictly in one direction, and pieces of triangular-shaped material are needed for the Sudeikin roof. Accordingly, if this material is cut diagonally, the second piece cannot be used.
Nevertheless, the roofs of houses of non-standard shape are slowly gaining a place in the sun. And, according to the reviews of their owners, they show themselves from the best side.
In addition to the large additional space that would be wasted if the roof was installed, they have several other advantages.
What gives this original design:
- All roof pitch angles convex, and there are no grooves between the slopes, which in winter are clogged with snow and ice, which leads to damage to the roof
- 90% of roof space is used
- Windows located on all gables provide very good illumination of the attic floor, without the need to use special roof windows.
- There are no horizontal sections of drains - a slope of 45 ° allows you to collect water through the gutters and divert it directly into the downpipes
- Snow also does not accumulate on this roof in large quantities.
No one will give an accurate forecast, but the current trend allows us to assume that over time, Sudeikin's roofs can often be found in cottage settlements. Of course, this solution is not for every homeowner, but the advantages of this roof are much greater than the disadvantages.
