For residents, who purchased an apartment on the top floor of an old building, and some modern layouts, there is a problem with arranging a balcony. Usually, such balconies do not have a covering slab, and the absence of a balcony above makes it impossible to create a living space on such a balcony. Therefore, residents have to decide this issue on their own.. Next we will consider how to make a roof on a balcony last floor step by step.
Types of roofs for balconies
The roof installation procedure is determined by its type, which one you decide to prefer. There are two possible options here:
- Installation of a dependent roof structure. It is most preferable for the top floor, because it is resistant to wind and snow loads. The design itself is quite complex and involves the installation of vertical metal racks. Its advantage is the possibility of subsequent glazing and thermal insulation work.
- Installation of an independent structure without support from supporting structures. In this case, facade fixation is required. Here you can save on costs, however, its reliability is significantly lower. It will also be impossible to install reliable glazing and thermal insulation., and materials for work should be as light as possible.
Preparation for arrangement and selection of materials
To carry out work on arranging a balcony roof, it is necessary to select the appropriate material:
- rolled metal sheets, such as corrugated sheets and metal tiles, which are affordable and suitable for all types of roofs;
- ondulin and other soft roofing materials. They are light and easy to use, however, they have fire safety restrictions;
- bitumen shingles, characterized by good noise insulation properties, lightness and resistance to external influences;
- polycarbonate or double-glazed windows for transparent coverage, which for the top floor must be selected taking into account increased solar exposure in the summer.
Selection of load-bearing structures
If you want to build a reliable structure, then it is advisable to pay increased attention to the installation of load-bearing structures. There are two options here - wooden and metal.. The first type is characterized by low cost and provides the advantages of low thermal conductivity of wood. However, installation requires reliability control, and the material itself is susceptible to weathering and may cause the entire system to move in the future.
Metal structures are more expensive, but also more reliable. Available with profile welded frame or screw connection. Also popular is the method of mounting on metal corners.. Next, we’ll look at how to make a roof on the balcony of the top floor step by step.
Roof installation procedure
Arrangement of a dependent roof requires the installation of a balcony glazing frame or a system of racks rigidly connected to the frame. It is advisable to install the roof in the following sequence.
Installation of the rafter system is carried out by securing the timber to the load-bearing walls using anchor bolts. Rafters are placed on top of the beam. It is also possible, when metal corners are attached to the wall. Minimum bolt recess depth 8 cm.
Installation of overhangs and sheathing. Installation of the sheathing is carried out by securing the longitudinal, and then cross bars. Distance between bars 50 cm. Fastening is done with self-tapping screws.
Antiseptic and fire-resistant treatment of all wooden elements is carried out.
Material for sound insulation and waterproofing is placed on the grille.
Thermal insulation material is placed in the free areas of the sheathing, secured with adhesive and dowels..
Using nails, a vapor barrier from indoor moisture is fixed to the sheathing.
Profiled sheets of the required size, cut with special scissors or a hacksaw, are attached to the sheathing. For such fastening, screws with spacers are used.. Or metal tiles or other roofing material are installed.
End strips are installed on the roof.
If the balcony is sealed, a ventilation hole can be provided. After the roof has been installed, the balcony can be finished from the inside. It will already be possible, for functional use of space, hang original wooden shelves, you can read about the design options in this article On the site http://onlyforemont.ru/.
