When a shed roof is installed and the features of its installation

shed roof on the house Now developers are increasingly beginning to build country houses with a pitched roof. Previously, it was installed in a barn, garage. A pitched roof has many advantages and a minimum of disadvantages. In addition to ease of installation, there are also features, which are described below..

When installing a pitched roof: features

The single slope roof is easy to install. It is installed on:

  • small garages;
  • country baths and saunas, indoor pools;
  • summer kitchens in private households;
  • outbuildings;
  • greenhouses.

The structures of such a project are mounted in summer cottages and private houses in areas with strong winds..


  • simplicity of design;
  • economy – less costs are spent on installation than on two-, four-slope structures;
  • no special skills or knowledge are needed for the construction;
  • saving time – following a step-by-step algorithm will save work time.

A properly designed structure will protect the structure from gusty and strong winds. And also it makes it possible to correctly use the space under it (arrangement of the attic).

The roofing material is slate, metal tiles, soft roofing products. Among all the advantages, there is a special one – the absence of valleys. These are vulnerable spots for moisture ingress..

Despite the pros, there are also cons:

  • if the building is not wide, then the attic is not equipped;
  • there is no way to make good thermal insulation.

A roof with one slope protects well from the wind in one direction. If the gusts change their direction, the whole structure is not reliable..

Types of pitched roofs

The single-slope arrangement is easy to manufacture, but the installation is carried out in different ways:

  • the design is warm or cold;
  • is there an attic room, attic or not;
  • installation is made of various slopes.

Shed roof projects:

  1. Smooth – the slope is covered with slate or other material.flat shed roof
  2. Rounded – a design solution for country houses.rounded pitched roof
  3. Curved plane – will stand out among all houses with its originality.curved roof plane

A flat, flat look can be combined with other types of roofing. Basically, these are multi-level structures – broken, semicircular, a different number of slopes.

Differences in the type of ventilation:

  1. The ventilated structure should be with an angle of inclination of 50 and 200. And also between the waterproofing and thermal insulation they make space for air flow.
  2. The angle of inclination of the non-ventilated type is less than 30 and 60. And also in the structure there is no air space between the layers of waterproofing and insulation. Mostly unventilated version is mounted on terraces.

Depending on the type, various materials are used that are most suitable in all respects. It depends on the weather conditions, as well as the purpose of the building..

Shed roof device

shed roof structureHow to make a pitched roof, because it consists of elements that give reliability, strength, warmth, dryness.

For a non-insulated structure, the following layers are applicable:

  • rafter system;
  • lathing;
  • covering (metal, slate);
  • gutter system.

The device of a shed roof of the insulated type:

  • rafters;
  • waterproofing layer;
  • insulation;
  • vapor barrier;
  • topcoat;
  • drainage.

Depending on the applied topcoat, they make a crate for vapor barrier..

Rafter structure

types of layered rafters

The pitched roof structure includes a rafter structure. There are 3 options:

  1. Supports used. If the width of the building is 4.5 m, then additional racks are installed. This gives the load distribution over the entire area. The width of the building is 6.5 m, support beams are installed in the center. With this construction, the roof is solid..
  2. Without supports. Supports are not installed with a span of less than 4 meters. Mount inclined rafters with support – Mauerlat on the wall.
  3. Sliding option. The load is applied to the strapping bar. The rafters are fixed to the walls with sliding fasteners. This is done to allow the building to collapse. Basically, this method is applied to wooden structures..

fastening the rafter leg

The device of the shed roof rafter system is produced in 2 ways:

  • on buildings where the walls are erected with different heights;
  • the main wall is raised and the top of the rafter leg is rested against it.

Supports are needed for the rafter leg. The number, the step of fastening depends on:

  • tilt in degrees;
  • weight of 1 rafter leg;
  • meters (centimeters) from the wall to the abutment of the roof;
  • rafter length;
  • topcoat;
  • insulation.

Installation of rafters is an important event in which a clear calculation is required.

Single slope roof gutters

gutter systemThe roof for 1 slope is erected at an angle. At the same time, the drain is made:

  • organized;
  • unorganized.

The system is produced outside. The gutters are installed from the bottom side towards the drain. All water is discharged into the drainage system.collection of water from multilevel roofs

pitched roof schemes

For mounting with one slope you need tools:

  • construction knife;
  • hammer;
  • stapler;
  • saw.

roof mounting toolsAnd also you need careful preparation for the upcoming work..

It is required to calculate the angle of inclination. It will affect the roofing material. For example, on a tile, slate, snow lingers on melting, but from the metal profile it will “move away”. The strength of the entire structure depends on how the roof retains precipitation..

The angle of inclination of the structure

roof slopeWith a slight slope, the structure is strengthened, covered with roofing material. The angle of inclination of the pitched roof is 5-100. Using slate – angle 200, tiles – 27-350. Consider the wind. If there are constant strong gusts, then the slope is made steeper, if the structure is protected by trees, then the roof can be made flatter..

Calculate the distance between the supports. They create structural strength. The parameter is calculated based on the weight:

  • roofing;
  • rafters;
  • hydro-, vapor barrier elements.

Step between rafters, depending on the length:table

If there is (will be) a chimney, then the step is calculated taking into account it, so as not to install the system for the supports later.

Necessary materials

materials for a pitched roof

To erect a shed roof with your own hands, you need to calculate the amount of material:

  • bars for props 12×12, 15×15 cm;
  • bars for lathing 50×50 mm;
  • floor board in the attic;
  • vapor barrier;
  • insulation;
  • nails or other fasteners;
  • waterproofing.

You can cover the structure:

  • metal tiles;
  • soft tiles;
  • slate;
  • corrugated board;
  • roof tiles.

The tree should be treated with linseed oil or other antiseptic solution, dried.

Installation of a roof on one slope

installation of a pitched roof

Do-it-yourself shed roof step by step:

  1. Beam strapping – installation of Mauerlat.
  2. Installation of floor beams. Fastening the rails.
  3. Installation of rafters.
  4. Creation of the lathing.
  5. Installation of waterproofing, insulation, vapor barrier.
  6. Finish coating.

Mauerlat for a pitched roof

Mauerlat installationThis element is installed on a load-bearing wall or between floor beams. It is fastened with anchor bolts, which are installed during the construction of walls..

Depending on what the walls are erected from, fasteners are installed:

  • wood – anchors;
  • foam blocks – fittings;
  • brick – annealed wire.

Before fixing wooden beams, you need to put a waterproofing layer.

Installation of the rafter system

installation of the rafter systemThe rafter system is the basis of the structure being erected. When installing it, it is necessary to observe accurate calculations and evenness. Installation is carried out as follows: the beams are attached to the Mauerlat. The step is determined based on the roofing material (50-80 cm). fixation is made with anchors or slate nails.

For the strength of the structure, it is necessary to observe the angle of inclination. For this, the first and last beams are installed. A thread is pulled between them.

Installation of lathing

installation of the lathingThe shed roof lathing is the basic component of the entire structure, on which layers of waterproofing, insulation, vapor barrier are mounted. The laying step is important here. A wooden beam 50×50 mm is required. It is fixed perpendicular to the rafter leg. In this case, the rafter board extends beyond the wall by 50 cm.

Also, the step of the lathing depends on the type of roof. Sheet – step 1.5 m, slate – 1 m step for lathing. If the roof is soft, then they make a solid crate.

Roof insulation, waterproofing, vapor barrier

installation of thermal insulationTo insulate the structure, protect it from leaks, for a long time, it is necessary to properly protect.

Sequence of fixing layers:

  • waterproofing element;
  • laying insulation;
  • vapor barrier.

Waterproofing and vapor barrier are overlapped. The joints are closed with adhesive tape. Fixation to the tree is made with a stapler.

Fixation of roofing material

fastening of roofing materialFixing the topcoat is the last of the basic steps in roof construction. The roofing layer is fixed according to the instructions for use. And also in compliance with the styling features.

After fixing the topcoat, additional elements are mounted, drainage.

The single-pitched roof is available in various design options – semicircular, flat, with a different angle of inclination. Do-it-yourself installation of a shed roof is also different. But, in order to achieve strength, durability in all stages of work, it is necessary to observe evenness, prudence. There is no need to rush and make mistakes. The quality of the work performed will depend on this..
