Like any other building, a bathhouse requires a roof. Does it have any features and special requirements? How and from what "according to the rules" a roof for a bath is arranged - later in the article.
In its design, the bath roof is subject to the same basic requirements as on any residential or commercial building.
It should protect the structure from the effects of the external environment: wind, precipitation, cold or heat. Therefore, both the bearing part and the roof itself are arranged in exactly the same way.
What should the future owner pay attention to?
There are several main points, and they should be taken into account in advance, since the alteration can be quite problematic:
- Roof shape:
- flat roof house
- Shed
- Double pitched roof
- Hip (four-slope)
- Roof type:
- Combined (non-attic)
- Attic unexploited
- Attic (with equipment for residential or technical premises)
- Aesthetic solution
- roofing roof material
Roofing materials for a bath
As a roof covering for a bathhouse, all materials available on the market can be used, and many go further and use reeds, clay-straw mixture and even turf.
True, the latter options, although very environmentally friendly, practical and have a service life of about 30 years, but the coating of them turns out to be heavy and requires a powerful truss system.
Advice! Sod covering is arranged on shed roofs with a slight slope, and is performed as follows: two layers of turf are laid on two layers of roofing material: the first is upside down, the second is down. The roof comes out very reliable, but in hot weather it requires watering.
Used for baths and lumber - shingles, wood chips, shingles. However, it should be remembered that these materials, without proper impregnation, are flammable.
Regardless of the roofing material, the presence of an attic or an attic, the overlap of the bath will require careful heat and vapor barrier, especially the steam room, since it is important to maintain a sufficiently high temperature and humidity (for a Russian bath) during use.
Otherwise, either the heating costs for these premises will be greatly increased, or the stove will not cope with the required temperature at all.
As a rule, on a suburban area, nevertheless, the type of roof and its material are chosen in relation to the style of the main residential building, as well as to the material of the walls of the bath. However, this is a matter of preference of the owner.
Also, the question is removed if the bath is built in a remote place of the site, and it is not visible at the same time as the house.Sometimes, on the contrary, the design idea is such that, say, a wooden blockhouse contrasts with the modern decoration of the mansion.
It affects the type of roof and the presence of an attic in the project. Of the most practical solutions, one can name an attic space under a pitched or sloping roof.
However, the first option is more expensive, since we are talking, in fact, about the equipment of the second floor - after all, in this case, the walls will have to be raised with the main material to the required level.
It is not without reason that a sloping roof is also called an attic - here a room can be equipped relatively inexpensively, while the usable area will be maximum.
ADVICE! If the roof structures provide for the presence of trusses, it is easier to manufacture and assemble them on the ground, and then lift and mount them directly on the roof. This will ensure higher accuracy and identity of all elements. If during installation there are still any inconsistencies caused by uneven walls or other factors, you can correct and adjust them already “in place”.
When installing an attic, the roof is insulated in the usual way. The main ones are three of them: fixing thermal insulation on the inside of the rafters, on the outside, and between the rafters.
The main thing is to observe the necessary sequence of layers and the distances between them, which depend on the materials used and the recommendations of their manufacturers.
For most coating materials, how the bath roof construction looks like this (from the room to the outside):
- Finishing material of the attic walls
- Vapor barrier (located from the finish at a distance of at least 5 cm)
- thermal insulation
- Waterproofing (5 cm of insulation)
- roofing material
The steam room and washing room located below are humid and hot rooms. Accordingly, the vapor barrier will let a rather large amount of moisture pass from the attic room towards the heater.
If you do not provide this layer with proper, especially intensive ventilation, it quickly gets wet, and begins to let cold inside the room.
However, with proper organization of insulation, part of the heat from the auxiliary premises will flow into the attic, and will serve as an auxiliary, and sometimes the main source of heat for it.
In addition, the chimney pipe will heat the same room - after all, it will pass inside.
However, in addition to heat, it will create certain problems, namely:
- Attic layout - the chimney will go in the place where the stove is located on the ground floor, or it will cross the room, breaking the space. In addition, it is desirable that the pipe enter as close as possible to the ridge in order to minimize snow retention in winter - and this may require serious adjustments to the truss system.
- There are increased requirements for fire safety, since the pipe should be located at certain standard distances from flammable and flammable materials
- In addition to the passage through the roof, which will be required in any case, it is necessary to carefully organize the passage through the ceiling
Even if an attic in the attic is not planned, the future owner should still take care of the correct chimney equipment. The attic will be cold, and the chimney will be hot in winter.
At the same time, the formation of condensate due to the temperature difference between them is possible both inside the attic and in the chimney itself (during its cooling), which will not benefit either one or the other. Therefore, the pipe in the under-roofing room must be carefully insulated.
Also, in all roof options, waterproofing of the pipe passage should be carefully performed - here there are often problems with precipitation getting into the under-roof space. There are special units of industrial production in which this problem is solved in advance.
ADVICE! Owners of wooden log cabins for a bath should remember that wood swelling is almost inevitable in damp rooms, and seasonal factors also have an effect on wood. All of the above allows for the possibility of wall deformations, sometimes quite significant. As a result, the roof may be damaged. This must be taken into account when designing the roof - for example, arrange it on hanging rafters.
There are a great many architectural and engineering solutions - fortunately, people in Rus' have always loved to bathe, and all components, including the roof of the bath, are quite honed.
So there is plenty to choose from, the main thing is that both the project and its execution are carried out in compliance with all technological requirements. And the bathhouse will warm its owners with its steam for many years.
