Do-it-yourself three-slope roof in a private house or annex - Step by step + Video No house is complete without building a roof. Roofs come in a variety of designs, even in very bizarre shapes and sizes, but the construction technology and materials remain practically unchanged. We will consider a three-pitched roof option. Such a roof is a combination of a gable and a hip roof. It is composed of three slopes, a pair of slopes in the form of a trapezoid and the third in the form of an equilateral triangle, it is the hip slope.

Building a roof

Do-it-yourself three-slope roof in a private house or annex - Step by step + Video The gable roof is slightly different in design from the gable roof, the difference lies in the setting of two rafters, they make up the hip ramp and structures that support the rafters.

Slant rafters are longer than side rafters and for this reason, you need to take boards longer and thicker or connect standard material.

Elements of a three-pitched roof

The frame of a three-pitched roof has the following components:

  1. Mauerlat - this is a beam that is laid along the border of the outer walls and carries the load from the roof to the walls of the building; Do-it-yourself three-slope roof in a private house or annex - Step by step + Video
  2. Lezhen is a transition bar. It is laid on the load-bearing walls of the building;
  3. Floor beams are boards, they are laid on the Mauerlat and serve as the skeleton of the floors between the floor and the attic or attic;
  4. Racks - this is a vertical supporting beam that holds the roof frame;
  5. Ridge beam - to lie on the vertical beam, which is a support for the roof truss system;
  6. Rafters - boards laid at a certain distance, they rest on the ridge beam and racks from above, and on the Mauerlat from below. Roof rafters are slant and side.

  7. Sprengel - vertical support supporting the slant rafters;
  8. Braces - bars that are placed at an angle of approximately 45 degrees, they serve as braces between the beams floors and rafters or lying. Do-it-yourself three-slope roof in a private house or annex - Step by step + Video

All roof components are connected with overlays, metal corners, studs with nuts or self-tapping screws.

Raw materials for the manufacture of the roof

For the construction of the truss structure and the lathing, coniferous boards are taken for work, previously prepared for work. Before choosing a material, carefully check it so that it does not have any traces of mold, darkening and rot.

An antiseptic and a fire retardant composition are used to protect wood.

Do-it-yourself three-slope roof in a private house or annex - Step by step + Video Beds, racks and Mauerlat are made from a bar with a section of 100x100, 150x150 millimeters.

Rafters and floor beams are made from boards of 50 mm and a width of 200 mm. So that the boards do not sag, they are installed with the narrow side down.

A large load falls on the slant rafters and a rectangular bar of 100x150 millimeters is used for their implementation.

The same rafters are made from spliced ​​boards: they take a piece of boards, put them between spliced ​​boards and connect them with studs.

The main thing in the construction of the roof is the lathing, for it they take boards from 20 millimeters and with a certain distance they are placed on the rafters, parallel to the ridge beam. Sometimes the sheathing is made solid of plywood, this option is suitable for soft roofs.

For the construction of any type of roof, the following materials are still required:

  • Roofing; Do-it-yourself three-slope roof in a private house or annex - Step by step + Video
  • Water protection and wind protection;
  • Insulation;
  • Vapor barrier;

We build a three-slope roof

The first step is to fit the Mauerlat. Along the length of the walls and join at the corners at an angle of 90 degrees, sliding to the inner side of the walls. Mauerlat is attached to the walls with anchors, previously rolled waterproofing material is laid on the walls in two layers.

The bar intended for the Mauerlat must be treated with an antiseptic. The beds are laid on the inner walls, after having laid a waterproofing coating between the wall and the boards.

Laying the Mauerlat

On top of the Mauerlat beams are laid from boards of 50x200 millimeters, possibly thicker. Boards are laid on the end, thereby increasing the rigidity. The beams are laid in order: first, the outer ones, then the intermediate ones.

Do-it-yourself three-slope roof in a private house or annex - Step by step + Video The distance between the beams varies from 50 centimeters to 120 centimeters, but when insulating the ceiling with the latest materials, the distance between the beams should be left in 60 centimeters wide insulation material.

The height of the floor beams can be adjusted using wooden spacers. On top of the ceilings, it is possible to lay the subfloor of the attic, for this it is necessary to take strong boards, while the installation of the roof will accelerate and the safety of work will increase.

Vertical posts are placed on the floor beams, or on the beds, they are located in the center of the roof. The racks are installed and aligned along a plumb line, then fixed in an upright position with jibs and temporary supports.

Racks are attached to the floor beams with metal or wooden linings. The step between the posts is more than 2 meters. The racks are placed at the edge of the roof, they form a vertical pediment where the rafters are connected to the ridge. The ridge bar is installed on the racks and fixed with corners with overlays.

The step to the corners of the hip slope and both cornices must be checked.

The roof must be symmetrical.

Side rafters are inclined rafters, which are fixed on top of the ridge beam, and below on the floor beams and Mauerlat. They are made according to a pattern: they try on a board to the attachment point of the extreme rafter leg and make cuts on it, they will be a support for the ridge bar.

Do-it-yourself three-slope roof in a private house or annex - Step by step + Video According to the existing template, make the required number of rafters, attach them to the ridge bar, then set them in place and make a cut from the bottom on each rafter leg and to the Mauerlat. The rafter legs are installed on the Mauerlat near the floor beams so that it is possible to connect the structure with studs.

This is necessary to increase the rigidity of the truss; the distance between the rafters is equal to the distance between the floor beams.

Reinforce the side rafters with struts, which are placed at an angle of 45 degrees on the floor beams. The struts and rafters are of the same thickness as the beams and is 50 mm. The upper part of the struts is attached to the rafters with studs.

Reinforcement of the side rafters with logs

Do-it-yourself three-slope roof in a private house or annex - Step by step + Video Mark the slant rafters on place: support the timber or boards in a rack and mark the upper oblique cut.

Saw out, then lean against the corner joint of the Mauerlat and mark the bottom cut.

Slant rafters are attached with the help of corners and overlays, for the strength of the connection, the rafters are reinforced with rafters - props that form a hip slope and rest on the bottom of the Mauerlat, and from above on the slant rafters.

Installation of slant rafters

Slant rafters need additional reinforcement if they have a large length, but they are secured with racks that are installed from below and fixed with trusses on the floor beams.

The temporary jibs are removed and the sheathing begins after the rafter system has been installed. It depends on the roofing, from which you will carry out the crate.

A sparse lathing of 25 mm board is suitable for corrugated board and metal tiles, a sheath made of plywood is suitable for a soft roof and ondulin.

This type of roof (three-slope) will ennoble any structure, be it a house or a gazebo. The resistance to strong winds significantly increases, as is the orientation of the hip slope towards the wind load.
