The roof is not only a decoration of the house, but also its protection. Ate in the place where the house will be built, constantly strong winds that will blow on the facade of the house, a half-hip roof is the best solution to the problem.
A half-hip roof is one of the varieties of hip roofs. What does she represent? In fact, this is an ordinary gable roof, but at the ends it has small overhangs, which are part of the structure.
Thanks to this structure hip roof withstands large wind loads. Under it there is enough free space for arranging a residential or utility room.
The pediments of the house are more protected from precipitation, and therefore are less blown and washed out. In addition, such a roof gives the house an unusual, fabulous look.
Such roofs are of two types:
- Half hipped gable roof;
- Semi hip roof.
How they differ can be seen in the pictures. These roofs have a complex structure and it will not be possible to save on material either. But, despite all the difficulties, such designs are not uncommon. Now let's look at the device of the semi-hip roof.
Roof device
The design itself is a truss system very similar to two pitched, only with beveled edges.
Next, a roofing “pie” is laid on it, which consists of the following “ingredients”:
- Roof. For this type of roof, a rigid roof is used. Metal tile and corrugated board are currently the most popular. These materials are distinguished by relatively low price, light weight, durability, aesthetic appearance and ease of installation.
Advice! Some materials have poor sound insulation. If you chose this one, you should take care of an additional layer that will absorb noise.
- Sheathing for truss system. It is designed for fixing roofing material. It is made from wooden bars or slats, which are attached perpendicular to the rafters on the slopes in a checkerboard pattern.
- The control grill performs several functions at once. It fixes the waterproofing and the crate is attached to it. Thanks to the counter-lattice, a gap is formed between the roofing material and the waterproofing, which contributes to better ventilation of the under-roof space. Mounted from the bars on the rafters, along their entire length.
- Waterproofing is designed to protect the insulation from moisture. Previously, roofing material was used for these purposes, but it collapses from the heating of the iron roof and its service life is not great. Currently, modern materials are used - diffusion membranes.They let steam and moisture pass only in one direction, up, which means that the insulation will be dry. This is a durable and reliable material.
- Insulation helps to keep indoors. For these purposes, you can use various materials: expanded polystyrene, mineral wool, polystyrene. It should be noted that some materials (expanded polystyrene) can be produced with a moisture and windproof film on one side. In such cases, it is not necessary to lay waterproofing.
- Vapor barrier protects the insulation from moisture from the inside of the roof. For these purposes, glassine, polyethylene, foil films or the same diffusion membranes can be used.
- Decorative finish. In order for the room to have a finished look, the half-hip roof, on the inside, is upholstered with clapboard or closed with plasterboard.
Although it was said above that the truss system of these roofs is similar to the gable system, it is much more complicated in design. The main thing here is a clear geometric calculation and competent execution.
So to the question of how to make a half-hip roof, it would be more correct to answer that you should contact the experts. But if a person is determined and has a skill in carpentry and construction calculations, then the main thing is desire and financial capabilities.
It is worth noting that for construction, you should purchase a well-dried and high-quality wood without knots and cracks. Before performing work, all wooden materials are treated with a fire-retardant solution. This will prevent fungus, mold and bugs from growing, and will also make the wood less flammable.It is also worth paying attention to the diameter of the logs and the dimensions of the timber.
Half-hipped roofs are always insulated. Therefore, the distance between the rafters is determined by the width of the insulation material.
Particular attention, when calculating and installing the truss structure, should be given to places where the rafters are connected into a corner joint.
And so, what conclusion can be drawn? A half-hipped roof is perfect for a building that is located in areas with strong winds. It has a complex design, but gives elegance to the appearance of the house.
It will not be possible to save on materials during construction, but the walls of the building will be reliably protected from wind and precipitation. As you can see, this type of roof has its pros and cons, as well as any other. Therefore, the choice is yours, and any difficulties can be overcome.
