Design features - Roofing system assembly project + Photo and Video In modern construction, thanks to the improvement of technologies and building materials, a huge variety of architectural forms and solutions prevails. But basically all the same, in the matter of choosing a roof structure, builders focus on practicality.

The attic space may well be equipped as an attic, which will significantly increase the usable area without building 2 floors. A full-fledged room will turn out in the attic. And here, in order to make normal walls, and not slopes, the best option would be to install a domed octagonal roof, which is called the Sudeikin roof.

A little history

A book published in 1914 by the talented architect G.M.Sudeikin, which contains a huge variety of design solutions, including drawings of the famous roofs. She gained her popularity after the release of this book. Was presented in five different projects of timber and concrete houses.

Design features - Roofing system assembly project + Photo and Video The main difference of this roof is that there is no rafter system in it. Its frame is a mullion-beam structure supported by a central post. The roof has eight triangles, 4 of them are pointed downwards, and the rest upwards.

Important: Such a roof can only be built on a square structure and allows ninety percent of the space under it to be used. In theory, such a roof can be arranged for a rectangular house, but as practice shows, this is quite difficult and will take a long time.

Sudeikin proposed many original projects for building houses. He created manuals containing accurate calculations and drawings, relevant to this day.

In one of his albums, the architect posted a comparative table, which proves that such a roof allows you to create the largest attic space with the least material consumption.

Thanks to the developments of Sudeikin, modern designers have calculated and thought out a domed roof with six sides, without support in the center. That allows you to almost completely organize a living room in the under-roof space.

Advantages and disadvantages

The following advantages of the roof are distinguished:

  • Maximum use of the attic ;
  • Due to the shape of the dome, an air space appears above the attic, insulating the warm space, which significantly increases its heat capacity;
  • The roof facilitates the natural melting of snow and water. This shape does not allow the formation of snow pockets and water stagnation;
  • Savings on roofing;
  • Natural cleaning of the roof due to the large slope;
  • Due to the large area of ​​the gables, it is possible create natural lighting with vertical glazing. This is important because the cost of roof windows installed directly into the slope is relatively high.

Disadvantages include:

  • Suitable only for square buildings;
  • Individual calculation of each structural element;
  • Not all materials are suitable for such a roof. So, due to the many turns and corners when using metal tiles or slate, there will be a lot of scraps.

    Here, coatings such as ondulin or bituminous tiles will be most suitable.

You are planning a balcony, this will also be problematic and part of the veranda will be open. Also, when installing a drainage system, you will need the help of a specialist in the selection of pipes necessary for the parameters. Many more gutters will be used here than, for example, on a gable view with the same area.

Professionals argue that the main drawback of the Sudeikin roof is that during its installation it is not possible to use a typical project.

Today there are not enough experienced specialists in this field.


The Sudeikin roofing system assembly project consists of the following stages:

  • Design features - Roofing system assembly project + Photo and Video Four short vertical supports of equal size are mounted at the corners of the box;
  • Above these racks, a strapping is made in the form of a regular quadrangle using beams;
  • Then the center of all horizontal beams and walls of the building is calculated;
  • One more identical vertical rack is attached to each horizontal beam from the harness, in total, for convenience, marks are made in the center with chalk;
  • The bars for the base are measured ;
  • Mount the inclined beams connecting the vertically standing pillars and the pediment trim;
  • Mount the support in the center, its size corresponds to the dimensions of the building;

Note : The center support holds all load-bearing boards. It is higher in height than other racks, due to which they get the same angle of the architect.

  • The support is fixed with special construction nails in the center of the frame, then the connecting beams are mounted. From the top of the gables, bars are placed towards the support pillar in such a way that the protruding edge is equal to the width of the cornice;

Important: When installing, it is imperative that these boards go beyond the walls , thereby forming an overhang of the cornice.

  • The gables are horizontally strapped using a bar, forming a regular square;

Installation of the surface crate

The beams are attached to the gables with studs; waterproofing must be provided between the wooden surface and the stone one.

Sudeikin emphasized that during construction it is necessary to use extremely powerful fasteners - screws, nails 100, 200, depending on the material.

Important: When installing each fastener, the structure must be checked for strength.Otherwise, your roof will last no more than twenty years.

Roofing material

The architect intended to use galvanized iron for the roof, but now there is a huge variety of coating materials. Some consider soft shingles or small piece material to be the most suitable for such a roof, since the sheet view will need to be trimmed and adjusted. Despite the advantage of soft tiles, they are quite expensive material.

In practice, ondulin, metal tiles and metal profiles are excellent for covering a multifaceted roof. With the right approach and the necessary calculations of the required amount, there will be practically no waste.


You yourself decide whether to use a project from the past, but none of those who chose such a roof for their home did not regret it.
