When building houses of complex shape, for example, supplemented with elements such as bay windows, it is necessary to pay special attention to the design and installation of the roof. The complex configuration of the house involves the use of such a structure as a yand roof.
Of course, such architectural elements as bay windows greatly decorate the appearance of the house and allow you to plan original interiors.
In addition, the presence of a bay window in the house will make the rooms brighter and more comfortable.But, the presence of this decorative element greatly complicates the installation of the roof, since it turns out to be multi-pitched.
The intersection of the slopes form an internal corner, and this place on the roof is the most vulnerable, since rainwater accumulates there.
This inner corner at the junction of two inclined slopes in construction is called a valley. Consider how you can build a roof with such elements.
Construction preparation
The first step in deciding how to put a roof of any shape is to draw up a project and select a team that will carry out the work.
It should be noted that a device of such a design as multi-gable roof This is a job that requires a high level of professionalism. Therefore, you should not try to perform it yourself, and the choice of a team of repairmen should be taken with great attention.
Armo-belt device above the bay window
If a roof is being built over a bay window, then the first stage of work is the installation of an armored belt. This building performs two functions at the same time:
- Creates a support for the beams holding the rafters;
- Reinforces brickwork and relieves window lintels.
An armored belt is made of concrete with reinforcement with a metal mesh. If at the same time the level of the walls of the bay window turns out to be slightly higher than the level of the walls of the house, it's okay. The fact is that in the bay window you can use rafters of a smaller thickness than for the main roof, such as hipped standard hip roof.
Preparation of materials
In order for a bay window roof to be built, the following materials must be purchased:
- Lumber for rafters, rafters and battens;
- waterproofing material;
- Nails, screws, studs, screws;
- Wire knitting;
- Galvanized plates.
Installation of purlins
The next stage of work, when a bay window roof is created, is the installation of rafter beams. For them, you can use a bar of the required length or spliced edged boards. Self-tapping screws and screws are used to connect the boards.
Advice! It is advisable to make rafter beams of such length that there is a small margin. . Then, after installation and fixing, the excess can be cut along the cord.
Building a rafter system
To choose the length of the rafters, it is necessary to accurately represent the angle of inclination of the roof being created. It is important to maintain the proportions of the roof so that the house does not look like a birdhouse.
In order to visualize the appearance of a future roof, such as a hip roof, three-dimensional modeling is used in the design.
The rafters should be prepared on the ground, after which they are lifted up and sewn together in the roof ridge using self-tapping screws and galvanized lining plates. Further, the two sides of the future "triangle" of the roof are attached to the rafters and braces.
Lathing installation
Waterproofing is installed on the finished rafter system. The film must not be installed in an interference fit so that it cannot burst during temperature changes. Therefore, it is attached with some sagging.
Advice! When using modern waterproofing membranes, it is convenient to use a construction stapler for fastening.
Then a crate is mounted across the rafters. The step between the individual elements of the crate depends on the type of roofing material chosen. For example, when using a metal tile, the distance between the boards of the crate should correspond to the width of the tile element.
Laying roofing material
The laying of roofing material during the construction of a bay window roof is carried out in the same way as when covering a conventional roof. But in this work there is a difficulty - the installation of valleys.
As a rule, two types of gutters are required:
- PEN (bottom bar of the valley) is a device that serves to drain rainwater, which will inevitably accumulate at the junction of the slopes
- PEV (respectively, the upper plank of the valley) is a decorative element for masking cuts on the roofing.
The valley planks are installed on a special board, which is called the valley. The joints of the gutters and roofing material should be treated with sealant. You can also use a universal seal.
Finishing part of the work
By laying roofing material and installing a valley, the solution to the question of how to properly put a roof over a bay window does not end. The final part of the work is carried out indoors.
It is necessary to lay insulation and install a vapor barrier. After that, you can proceed to the interior decoration - hemming the ceiling.
