How to make a wing on the roof with your own hands - design
In the context of the current constant increase in the cost of land, housing construction is growing in a vertical direction. Developers increase the useful area of houses due to the equipment of residential comfortable lofts. But what to do if there is still not enough space, and there is no free land for the construction of an extension? Experienced craftsmen believe that in this situation there is only one way out - the wing on the roof.
What is a wing?
Most people, when they hear the term "outbuilding", are small, separate from the main house construction, used for business purposes or as a summer guest dwelling. In fact, this word of Germanic origin, which literally means “wing”, has three meanings:
- Separate economic or guest facility, located at a small distance from the main residential building.
- A small, often unheated extension to a residential house, which can be used seasonally as a summer kitchen or an extra bedroom.
- Small extension on the roof of the house, which can also be called a mezzanine.
Please note that the outhouse on the roof can be used to equip a small office, nursery or playroom, and if you make a roof of molded polycarbonate, then in this room you can place a winter garden or a greenhouse.
Arrangement options
According to the reviews of professional builders, arrangement of the outbuilding on the roof is the cheapest way to increase the useful living space of a private house. However, in addition to this function, a small extension makes the appearance of the roof more original, decorative and intricate. There are 2 options for installing a mezzanine on the roof:
- The easiest, economical, and practical way to install a wing on the roof is to plan its construction during project preparation. This option allows you to accurately determine in advance the total weight of the house, taking into account the weight of the mezzanine, to make the foundation and roof frame sufficiently strong.
- The second way to build a mezzanine is to reconstruct the finished roof. However, at the same time the roof truss system is rebuilt, the load on the foundation is redistributed and the roof covering is impaired.
Important! From the point of view of the volume and complexity of the work, as well as the amount of costs, it is much easier to plan the construction of the outhouse during the drawing up of the project at home. In the case of reconstruction of the already finished roof, it will be necessary to almost completely rebuild the roof frame and remove the roof covering.
The influence of the outbuilding on the design
Experienced craftsmen that the outhouse can be attached to almost any private house. When planning such a cardinal reconstruction, it is necessary to take into account the design features of the roof, the height of the building and the height of the house, the bearing capacity of the foundation, load-bearing walls and floors. After all, the extension of the mezzanine to the roof has a huge impact on its design:
- Significantly increases and redistributes the load that lies on the foundation of buildings, floors and load-bearing walls. Weight gain can lead to sagging or warping at home.
- The tightness of the roof covering is broken. The extension of the outhouse increases the number of joints and abutments to the vertical surfaces of the roofing material, which leads to an increased risk of leakage.
- To break and violation of the rafter frame. To attach the mezzanine to the roof, you need to partially disassemble and make inset in the rafters, which violates the integrity of the frame.
- The shape and geometry of the roof changes, which affects the resistance to wind and snow loads. Because of the wing, the windage of the structure may increase and snow pockets may form.
Remember! In order for the outbuilding of the outhouse not to have a devastating effect on the roof and the house as a whole, it is necessary to calculate in advance the increase in the load on the foundation, and also to use lighter materials for building, for example, a sandwich panel.
Mounting technology
It is believed that the installation of a mezzanine on the finished roof is a rather complicated process in terms of technology, which is better to be entrusted to experienced, professional craftsmen. All manipulations should be carried out only in accordance with the project. Usually the installation process consists of the following steps:
- Partial or complete dismantling of the roofing of the main roof. If the roof has a large area, and the outbuilding will occupy only a small part of it, then you can not completely remove the roofing material.
- By means of wooden overlays the rafter frame is strengthened. Reinforcement is performed where the outbuilding will be attached.
- Make the frame of the mezzanine, and then sheathe it with sandwich panels or wood.
- The design is insulated from the inside with mineral insulation, and the outside is sheathed with decorative material.
- Gather the roof frame of the outbuilding roof, and then cover it with roofing material.
Important! When arranging the mezzanine, I pay great attention to the junction of the roofing material to the vertical surfaces, additionally isolating them. These places often cause leaks.
