If you decide to make an extension to the house, then this article will help you properly equip a pitched roof on it.
The purpose of the roof of any building, including an extension, is to protect it from rain and snow, heat and cold. At the same time, it has an aesthetic component, which allows you to give the extension individuality.
Shed roof for veranda
When choosing a roof for an extension, you need to clearly understand what its functional purpose is. For example, if the extension is to be “cold”, a lean-to roof of the extension is being erected, but if you dream of a well-equipped attic, that is, of a fully-fledged space above the extension, then the roof can be of an angular type.
The shed roof of an extension to the house, consisting of a rafter system and a roof, is quite simple to erect. First of all, the required angle of inclination for the future roof is determined. This will allow you to determine the difference in level between the front and rear walls of the extension. Next, a wooden frame is made, a rafter system is installed and the roof is equipped. Considering that the extension is still not intended for housing, then, obviously, there is no point in choosing an expensive material for the roof. Fortunately, today there is an opportunity to buy a roofing material that meets the taste, design preferences and financial capabilities of the home owner ..
If earlier, for the most part, it was slate, now it can be a more modern inexpensive lightweight roofing material that will not stand out from the overall design of the house. For example, if you opt for a metal tile, then given that the slope at the roof of an extension is, as a rule, not very long, the metal tile can be laid in one sheet, that is, without joints along the length.
If, according to its purpose, the extension should be warm, then the question arises of roof insulation. A special material for insulation is laid between the beams of the rafter system on the auxiliary crate. In the future, the rafters are sheathed, for example, using drywall or plywood.
The lean-to roof of the extension is familiar to anyone who has not seen the veranda, which makes the house more beautiful and attractive.
When building a veranda, the roof is usually made with one slope and at the same time, two trusses connected in series are combined. At the beginning, it is necessary to lay the roll-over beams on the top of the short sides of the veranda. Their thickness should not exceed 100 mm, and their width is about fifty. The installation step is 0.6-0.7 m. The beams rest at one end in the upper strapping. Nails are used to attach the beams to the veranda wall in this place. The second ends of the beams are led directly into the walls of the house. Next, they proceed to the construction of the rafter system. For rafters, beams are used with dimensions of 150×150 mm.
For their laying, the same step is used as for the upper floor beams, that is, 0.6-0.7 m. The floor beams are under the rafter beams, that is, they are the projections of the latter. The rafter beams are fixed together with the floor beams. With their second end, the rafter beams of the roof of the veranda are attached to the rafter beams, but already at home.
It happens as follows. Both in the rafter beams of the veranda, and in the rafter beams of the house, they make the same holes, where thin pins are then driven. Then they are tied together with a wire. It is wrapped at least twice around the rafter and rafters. A similar procedure with wire is repeated on the other edge of the rafter beam.
To give greater reliability and stability further between the beams, the rafter and the ceiling of the veranda, at a distance of 30-50 cm, starting from the upper harness, a part of a round log is placed. After that, with the help of reinforcement, they pierce the rafter beam from above, after which the reinforcement is driven into a round log. So that it does not move and go to the side, the log is fixed with two supports located on either side of it. Pieces of timber, nailed, act as a support. They are nailed to the floor beams.
Veranda roofs, depending on the architecture of a particular house, can be installed in different ways. For example, when constructing a veranda, which is attached from the side of the pediment, it is more expedient to arrange the roof of the veranda in such a way that both roofs, houses and verandas, have a common slope. In this case, the roof trusses have the same slope, and thus there is no need to arrange different gutters or valleys. And, as you know, they increase the risk of leaks at the interface.
Usually the same roofing material is used for the veranda as for the house. This is dictated rather by aesthetic considerations.
First, the roof sheathing is mounted: unedged boards are laid horizontally. The laying step depends on the material for the roof. For example, for a roofing material roofing material, a continuous flooring of boards is arranged, which is fixed to the rafters with the help of nails. Their caps will necessarily “sink” into the boards themselves.
The roof of the veranda has a small angle of inclination, so sheet roofing material should be laid with a large overlap.
The roofing material laid on the slope of the veranda must necessarily go under the lower edge of the material for the roof of the slope of the house by at least 5 cm, otherwise, with heavy rains, water can seep through the joint between these slopes. published by econet.ru
