If you decide to take on such a complex construction as a half-hip roof with your own hands, then you will be interested to know some information on this topic. For example, what materials to use and what is the sequence of work. You can learn all this from our article.
The semi-hip gable roof is a conventional gable structure at the top, and a trapezoid at the bottom (at the level between the first and second floors).
The slate roof view gives the whole building a very interesting and original look, clearly shows the line between floors. This design is more often used for small houses.
The half-hipped mansard roof (four-pitched) is a mansard structure with a broken slope.It is done in cases where the area of \u200b\u200bthe desired room does not fit into a triangular shape.
As a result, quite a lot of free space is obtained under the roof, which can be used at your discretion.
Do-it-yourself semi-hip roofs It is recommended to install on houses that are located in a zone of strong winds. This is due to the fact that the lower slopes well cover the gables of the house from moisture and winds.
By design, these roofs represent something between a hip roof and a conventional gable roof.
So where do you start building? With calculations, of course. If there is no knowledge in this area, it is better to order a calculation - a half-hip roof + a drawing from specialists.
Then, in accordance with the figures received, material should be purchased. When buying, you should pay attention to the quality of wood. It should be dry, without knots and cracks. Before starting work, all wooden elements are treated with a protective solution.
Advice! The roof must be strong and reliable. Therefore, the exact growth and conscientious performance of all work is so important. Experts do not recommend beginners to take on such complex designs, because one mistake can lead to unforeseen consequences. If you really want to make a roof with your own hands, let the truss system be installed by professionals, and you will take care of the subsequent insulation and installation of the roof.
We will briefly dwell on the sequence of assembling the truss system, since this design is complicated for beginners, and experts themselves know what and how to do.
The sequence of installation of the truss system.
- A screed is poured along the perimeter into which studs with a diameter of at least 10 mm and with a step of no more than 120 cm are mounted. Then the surface is covered with a waterproofing material.
- Holes are drilled in the support bars for the studs, and then we put the beam on them. The hairpin should protrude 2-3 cm above the beam. Washers are put on them and then nuts are tightened. These are the support bars (Mauerlat) on which the rafters will rest.
- Next, layered or hanging rafters are installed. Which option to choose depends on the size of the roof and whether or not there are load-bearing walls or supports in the middle.
Hanging rafters rest on the outer walls. The load on them is great, in order to reduce it, a puff is made, which connects the rafter legs to each other.
Laminated rafters abut with their edges against the outer walls, and with the inside against the supports or inner walls. This design has less weight and saves on material.
- At the top, a ridge run is laid, which connects the rafters to each other. In the places of the hips, the rafters are not attached to the ridge, but to the extreme rafters of the main gable roof.
- Intermediate rafters are installed. The step between them is usually equal to the width of the insulation material (60-120cm).
- Cross bars are installed.
After the truss system is installed, the installation of a half-hipped roof can be considered complete. Now proceed to the laying of roofing material, waterproofing and insulation.
Work can be performed in the following sequence:
- Thermal insulation is installed between the rafters. For these purposes, you can use expanded polystyrene, pressed mineral wool, etc.
- Waterproofing is laid on top of it. Previously, rubiroid was used for these purposes, now diffusion membranes.
- The waterproofing is fixed with a counter-grid, which is stuffed over the membrane onto the rafters.
- Further, the crate is attached in a checkerboard pattern. If the roof is soft, the lathing is made of OSB sheets.
- Roofing material is laid on the crate and fixed.
- On the inside of the roof, we close the insulation with a vapor barrier.
- Then decorative trim is made.
- Skates are installed on the roof, a cornice box is made and sheathed.
Of course, a half-hipped roof is a complex but reliable design. But she, like everyone else, needs good ventilation. This question should be considered in advance.
The under-roof space is ventilated thanks to the counter-lattices; ventilation grilles must also be provided in the cornice box. If everything is done correctly, the roof will last a long time without requiring repairs.
From all of the above, we can conclude: a do-it-yourself half-hip roof is a responsible and difficult task. Therefore, before taking on it, you need to “soberly” calculate your strengths and capabilities.
