Roof device for a bathhouseThe roofing of a bathhouse is somewhat different from the roofing of any other building. This is because the main load (high temperatures and humidity) falls on the inner side of the roof.
This especially affects the wear of the roof in baths, which are used all year round. Therefore, it is very important to choose a type of roof for a bath to minimize the load of climatic impacts on the environment from the outside.
- Single-pitched. Most often used if the bathhouse is located right next to the house. A bathhouse with a single-pitched roof should not have an area of more than 15 square meters.
- Gable roof. If frequent rains and snowfalls are typical for the type of terrain, then the angle of inclination of the planes to each other should be made as large as possible (up to 45 degrees). Precipitation will not linger on the roof and damage the roofing. In areas with frequent winds, the slope of the slopes is made more gentle to reduce the wind load.
Depending on the area of the bathhouse, the design of the gable roof allows you to organize an attic. The additional space can be used as a storage place. In addition, the thermal insulation of the entire building is significantly improved. If space allows, you can arrange the attic as an additional living space, a recreation room, or a billiard room. In the summer, the roof of the bathhouse with a veranda will give you a unique feeling of relaxation after the steam room. It is better to entrust the design and construction of such a rather complex project to experienced professionals.

Installation of a bathhouse roof
Construction of a bathhouse roof begins with the assembly of the supporting structure of the roof-rafter trusses. The system can be assembled on the ground and then mounted on the roof, or everything can be done at once on the log house.
- A mauerlat is laid in the upper part of the wall, and rafter beams are attached to it with iron brackets at a distance of one meter from each other. To prevent damage to the roof as a result of deformation of the walls due to moisture, the roof for the bathhouse can be built on hanging rafters.
- Then the rafter trusses are sewn together with a ridge board.
- Depending on the type of roofing, continuous or step lathing is attached to the rafters.
- If there is no attic, the gables are covered with a solid layer of plywood or boards. Otherwise, an opening is made for the door and window.
- The lathing is covered with roofing material.
Thermal insulation of the bathhouse roof
A competent installation of a bathhouse roof is impossible without high-quality thermal insulation.
The formation of condensation in winter, the level of heat retention in the washroom and steam room, and the safety of all wooden materials depend on this. Mineral wool, glass wool, or polystyrene foam can be used as insulation. The insulation sheets are laid between the rafters, under the rafters, or on the rafters.
A slightly larger sheet of fibrous insulation is laid between the rafters. In other cases of laying insulation, all sheets are laid overlapping, creating a continuous coating. Then comes the waterproofing layer and everything is covered with boards. Sagging of the waterproofing layer is not allowed, so as not to disrupt the natural ventilation process. A small draft in the attic is quite sufficient for ventilation of the under-roof space. When covering the ceiling, it is necessary to lay a vapor barrier material and a layer of thermal insulation. The roof for the bathhouse can be covered with any roofing materials.
The type of roof, the angle of the slopes, and the type of sheathing depend on the choice of covering. A small pitched roof for a bathhouse can be used for a very interesting turf covering. A layer of turf is laid on roofing in two layers with the roots up, and a layer of turf is laid on top with the roots down.
