The design of the roof for the house should be selected taking into account its number of storeys and architecture. Today, many developers choose. Its reliability is quite high. Such roofs look spectacular and solid. They are usually arranged over houses large area. One- and two-story houses look especially attractive with hip roof.
If on attic floor it is planned to create living quarters, it is necessary to equip the roof window openings. This is how it is created optimal lighting rooms. The hip roof is more gable, although the area of \u200b\u200bthe building may be the same. For this reason, the cost of its construction is higher. The hip roof project must take into account many nuances, so its creation should be taken with the utmost responsibility.
Hip roofs have several distinctive features. It consists of several combined slopes of different geometry. They are trapezoidal and triangular in shape. The connection of the slopes occurs with the help of a ridge beam. The first thing you should pay attention to when choosing a hip roof project is the angle of the slopes. This indicator affects the removal of precipitation and melt water. The angle can be either 15 or 65 degrees. This characteristic depends on many factors that should be considered when constructing a roof:
Attention! It is possible to increase the angle of the roof slope only with an increase in the roof structure as a whole. Such a decision will entail an increase in the consumption of materials.
In the design drawing, the parameters of the rafter system must be indicated. This applies to any roof. There are 2 main options for truss systems used for a hip roof:
When the hip roof project is determined, you can start the roofing for own house.
Before starting construction, an accurate design drawing should be prepared. Such a document is required when creating a reliable roof. The strength and stability will depend on the accuracy of the calculations. roofing system. The hip roof is given Special attention due to the complexity of its design. It is better if the project is carried out by a specialist. At the same time, the work will be performed qualitatively, and a guarantee has been received on it.
You can complete the project yourself, but for this you will need to have basic knowledge of descriptive geometry. In addition, you should be aware of the resistance different materials. A drawing must be made. It is better to draw the roof in several projections. Great if a 3D project is completed. This design looks especially attractive on one- and two-story buildings.
Another option is to create a house project with a hip roof in a special program. You can quickly figure it out on your own. For creating quality project You can use multiple programs.
If the project is decided to be carried out independently, it is necessary to take into account several important nuances:
If all these subtleties are taken into account, it will be much easier to build a hip roof.
Before work, it is necessary to take into account the amount of materials that will be needed to create the roof. Based on this indicator, design is carried out. Usually calculate how much you need roofing, steam and waterproofing, rafter legs, support racks and thermal insulation material.
The calculation of the amount of all materials is carried out taking into account the area of \u200b\u200bthe slopes. Since they are triangles and trapezoids, you need to familiarize yourself with the specific formulas for these figures.
Self-calculation will not take much time. If you calculate the amount of lumber, you need to take into account the features hip roof. These include the choice of the angle of inclination of the slopes and the area of the building. The smaller the width of the house, the smaller the area of the triangular parts of the roof.
You can build a hip roof with your own hands quite quickly. To do this, you need to follow a special algorithm. First, the Mauerlat is mounted. As this element, a log or timber is chosen, which is laid on top along the perimeter of the wall. Then you need to follow this algorithm:
Before building a hip roof, an accurate project should be drawn up. This is necessary to ensure the reliability and stability of the structure. In addition, this approach will save on building materials and reduce time costs. If the roof is created by hand, its project is carried out according to a simple scheme. The main thing is to understand the scheme. It is better to entrust the drawing of a hip roof to a professional.

The house is an integral part of the life of any person. And no matter where you live own house or rent.
Or maybe you are in this moment are you doing it?
For those who decide to build a house on their own, it is important to remember that special attention should be paid to the roof.
This structural element is of particular importance, both from an aesthetic point of view and a practical one. After all, he will have to protect the entire building from various weather conditions:
Therefore, before construction, it is necessary to think in advance what shape the roof will have? What roofing material is better to block it? Make the necessary before the start of construction, so that there are no problems during the overlapping period.
It is better to select the form, focusing on the climate of the region where you live. It depends on how effective the protection of the entire building will be in different periods of the year.
They are divided into:
Each of them has its own advantages and disadvantages.
But in regions with frequent precipitation in the form of rain, snowfall or hail, it is best to install pitched options.
Due to the angle of inclination, precipitation does not accumulate on the plane, but descends along the slopes into special whirlpools. The angles of inclination are selected in accordance with the desire of the developer, starting from 10 degrees.
They are also divided into several types:
There are a number of factors to consider when choosing the right shape: how heavy rainfall is in your area; whether the winds blow and especially what strength and duration, this is important for choosing suitable angle tilt.
Roof types
The main difference between the hip roof and all is the presence of four slopes. consists of two large parts, which are shaped like a trapezoid, and small triangles.
This species was named because of its triangular slopes located on the front side.
To build such a structure, a double screed and beams are required.. It should also be equipped to each slope so that moisture does not damage the walls of the house.
When planning the design of gutters, you should consider where the precipitation will flow, some combine drains with a common sewer system. But here it is important to take into account the amount of precipitation in your area.
The hip roof has a lot of advantages, the main of which is wind protection against strong gusts. Such a design is less subject to deformation and lasts much longer than a gable roof.
When you have decided on the angle, you should begin to calculate the gap between the rafter legs. The distance depends on the severity of the roofing material - from 60 cm to 1 m. After that, the amount of material to cover is calculated.
When proceeding directly to the installation, you should follow some rules:
As advice:
Pay special attention when calculating and designing a hip roof. If you are in doubt about own forces then consult with professionals.
Hip roof device
Tilt angles
The attic when building a house is not so much an attribute of practicality as aesthetics. Nice to admire the view from the windows of the attic.
Designing an attic, if you have chosen the hip roof option, is quite complicated. So should carefully carry out preliminary calculations on the drawing.
Marking, for the future installation of a hip roof, should be done along the lower part, where the attic floors will be located. On the end side, the center is indicated, it is there that the ridge beam will pass.
The main difference in design is the placement hip rafters. They don't tighten up, as is done, for example, when building a gable roof.
So the load will fall on the ridge beam, diagonal and ordinary rafter legs rest on it.
Building a hip roof with an attic will add sophistication to your home, but it will require serious power costs, not to mention money.
Four-pitched roof with attic
If you do not plan to settle in the attic of the house, then this will simplify the construction of the roof. Since the hip roof has a gentle slope, short rafters can be used for a structure with a smaller section, which will significantly save the construction budget.
A residential attic will require a design review, including reshaping the roof or significant elevation. beam ceiling. A similar solution can be applied to the construction of large cottage houses, where the dimensions of the structure allow you to equip the attic under the room.
Hip roof with attic
The choice of the future developer offered different variants hip roofs:
Projects one-story houses with hipped roof:
Project wooden house with hipped roof
Project of a house with a metal roof
If the difficulties do not scare you, then you can independently build a hip roof. Thanks to the positive aspects, this roof shape will give you comfort and convenience, as well as attractiveness.
The type and structure of the roof is influenced by the architectural specifics of the residential building being constructed. Taking into account such nuances, the roof is divided into separate options: complex (curly), as well as flat types of roofing. Each of them has some specific features. truss system, various shape roofs (in the photo - a version of the roof for a country house).
The difference in the truss system lies in the slope. In the case when the slope of the roof of a private house does not exceed ten degrees, professionals consider such roofs to be flat.
In the presence of a more significant slope, we are talking about the construction of a pitched roof (example in the photo). There is their classification according to the purpose and the number of slopes used.
Roofs of private houses pitched similar in structure, suggest the presence of the same type of elements in the structure. At any pitched roof the following elements are present:
Having an idea about the device pitched roofs Let's take a look at some of their types.
This type of roof for houses is used quite rarely. Basically, a similar design is used in the construction of various outbuildings, storage facilities, garages, shops.
Attention! Such a roof is characterized by a certain truss system, in which the beams installed for the roofing material rest on the walls of the house and are smooth guides.
Among the main positive characteristics of this version of the roof, we highlight the ease of installation.
In the construction of private houses, roofs of this type are quite common. This version of the roof assumes two slopes, which are based on walls of the same height. Often such a design is called a gable design, since it implies the presence of gables that resemble triangles in their format. The roof truss systems of private houses, consisting of two slopes, have quite a few differences from a simple pitched roof. In addition to external differences, they differ in the complexity of installation.
The construction of a hip roof for private houses is a difficult task, as it consists of four slopes. Two slopes of this design are similar in shape to a trapezoid, and two slopes are made in the form of smaller triangles. Such triangles, located on the side of the gables of houses, are called hips.
This version of the roof is quite often used in private construction, it is ideal for houses with rectangular shape. The four-slope hip structure is open to winds from all directions, so the hip structure always remains clean. Snow, various debris, dirt is completely blown away from it.
Such hip structures are suitable for houses with complex geometric shapes. Such roofs have many valleys ( internal corners, which are formed as a result of conjugation of roof slopes) and external ribs. It is precisely because of such internal and external interfaces of planes that the installation of this type of roof becomes much more complicated.
The truss system of this type of hip roof consists of many ribs that are installed in different planes at different angles. The ribs are connected into a single scheme, in which each individual element has its own function.
A variation of the double-sided design is attic construction. It is equipped to increase the internal size of the attic. Such a result can be obtained due to a break in a straight plane, which is why it is called a broken roof. broken structure in terms of the difficulty of installation, it is practically not inferior to the arrangement of a simple gable roof. This design is only used in residential buildings, which assumes the presence of a spacious attic.
This option is not typical for private construction, since a minimum slope is assumed. Such roofs can hardly withstand the load from snow in winter time, That's why similar designs not used for large areas. When arranging a truss system under it, metal or reinforced concrete structures. According to the device, such structures are similar to pitched options, they are also characterized by crate and rafters. At flat roofs no inclined ribs, ridge.
Advice! Flat roofs are great appearance, you can additionally equip them with a corner for relaxation, make a summer terrace with a flowering garden.
When replacing the gables with two slopes of a triangular type, a hip roof is obtained. Embedded at the top of the slopes dormer windows. Since the construction of such a structure will require special skills, without professional help you can't do it. In terms of stability, this version of the roof for a private house has no analogues; the roof can easily cope even with strong winds.
In addition to the hip design, semi-hip options can also be used in private construction. They are considered intermediate option between hip and double slope design. In this case, the end gables are made in the form of a trapezoid, their top is covered with half hips. Basically, in such structures, a window of sufficient size is located on the pediment; the half-hips themselves are unusual decorative elements.
AT modern construction they also use such a variant of the half-hip roof structure, in which the pediment has a regular triangular shape, a dormer window is organized in it.
It is used for houses built in the form of an equilateral polygon or square. The specificity of this design lies in the fact that the slopes are made in the form of a triangle converging at the top at one point. It will be difficult for a beginner to build such a structure on their own; the help of a professional builder will be required. From a constructive point of view, such a roof has three or more slopes. This option does not assume the presence of a ridge, the kats are symmetrically located in relation to each other. With a square or polygonal shape of the house, most often used tent option roofs. She behaves well in relation to strong winds. In addition, such designs offer a lot of opportunities for practical implementation complex design ideas. The presented plot discusses in detail all the features of hip structures for roofing, which are most often found in modern private construction.
Introducing new project from our architectural bureau - a project two-story house with a four-pitched hip roof and a garage in DNP Oboldino-1, Moscow Region. Working with the customer, we proposed to arrange two-storey house in corner area site. Such a location has several undoubted advantages, one of them is a large free space on the site where you can place, for example,. Another advantage is that in front of the garage there is an additional area for parking two cars.
Let's walk around the house. On the ground floor there is a large kitchen-dining room combined with a living room, a guest room, a dressing room, a convenient pantry, a boiler room, a bathroom, as well as cozy terrace with barbecue. The layout of the kitchen-dining-living room area is open, which is undoubtedly an advantage.
We can buy finished project hipped roof houses
The customer during the design process explained that he himself is a big fan of spending time at the stove in the kitchen, preparing culinary dishes for his family. Therefore, almost in the center of the kitchen-dining room there is an island with a stove and working area to prepare delicious treats for all participants in the subsequent meal.
The dining table is placed closer to the windows. The space around the table is lit on a fine day bright sun immediately from three huge windows on two sides of the world. After a hearty meal, you can continue a leisurely conversation in the adjacent living room. On the second floor are the parents' bedroom, two children's rooms, two dressing rooms and two bathrooms. Everything is done for a calm and serene rest of the whole family after an eventful day.
The main advantage of this project is a garage for one car combined with the house and a terrace with a barbecue area. These buildings surround a two-story house, merging with it into a single architectural style. The roof of the terrace and garage is visually a continuation of the hip roof of the house.
For the house of our customer, it was a hip or hipped four-slope roof that had unique advantages, including the ability to withstand wind loads. The angle of inclination and the height of the roof were chosen based on calculations of wind and snow loads in the area.
lack of gables and large overhangs make the facade of the house harmonious, close to the "golden section", i.e., almost ideal proportions of the whole house. In addition, such overhangs to a greater extent protect the facades of the house from all sides from atmospheric precipitation.
Entrance to the terrace and garage is possible both from the house and from the street. It is very convenient when in bad weather you can drive into the garage and go into the house with heavy bags without getting your clothes wet.
At the time of buying standard project home binding - Free!
Between the garage and the terrace fit a bathroom and a boiler room. The chimney from the boiler room and the barbecue stove is single and combined with supply and exhaust ventilation which also saves space in the house.
Terrace with barbecue is a great place for socializing and entertainment. friendly company. On the terrace there is a small kitchenette with a sink and a working area where you can cook excellent meals without entering the house and without disturbing the household with your presence. Although the terrace is open, it will always be warm on it, even in winter, when you are surrounded by close friends, like-minded people at a luxurious table. The heat is coming not only from the barbecue stove located on the terrace, but also from a friendly conversation with faithful comrades.
The material of the walls of the house is large-format brick. The project of the house is designed in such a way that none of them need to be cut during construction, which increases the speed of construction, while simplifying it.
A hip roof is a type of four-pitched roof, in which two slopes are trapezoidal in shape, and the other two (end) are triangular (having the same name as “hips”). If the end slopes occupy the entire area from the ridge to the eaves - this is a hip roof, if they do not reach the cornice - a half-hip roof.
The roof of the house performs a dual function - on the one hand, it is entrusted with protecting the building from external influences, and on the other hand, it is designed to decorate the building and give it individuality.
Historically, in Russia, preference was given to simpler one-, gable roofs, Europeans prefer a hipped or hipped roof, which has advantages and disadvantages under certain conditions.
Pros:
Minuses:
Since the shortcomings are not critical, the hip-type four-pitched roof is actively practiced in the modern construction of private houses.
When studying the device of the hip roof truss system, it should be noted that within this type, there are several types of structures. In turn, this changes the general process erection of the frame of the truss system.
Differs in the support of the diagonal ribs on the support beam of the ridge and the location of the overhangs at the same height. Individual elements hip roofs correspond to a triangle (gables) and a trapezoid (slopes).
Distinguished by the absence of a ridge support beam. This leads to the fact that all diagonal ribs converge at a single point, and ordinary short rafters already adjoin them. Such a roof is preferred in the presence of a square box at home. But the formation of a reliable ridge knot quite complicated.
It is distinguished by the presence of vertical gables in which windows can be installed. The picture shows the difference between two varieties of half-hip roofs (Dutch and Danish).
The most difficult in terms of construction is the design of the hip roof truss system, since in this case, all the roof slopes have a different area and diverge under different angles. A broken (mansard) roof allows you to more rationally organize the internal under-roof space and, in addition to additional living space, give the house a spectacular appearance.
Regardless of the type of roof, all types have the same elements of the hip roof truss system:
ridge support beam or ridge beam - used for a classic hip roof, it acts as a supporting element to which diagonal rafters are attached;
diagonal rafter (side, edge, slanting or corner rafter) - a longer rafter leg that attaches to the butt ridge beam at an acute angle, forming one of the sides of the triangle;
central rafter - boards of the same length, which adjoin the ridge beam and form the edges of the trapezoidal roof slope. Between them are intermediate rafters;
intermediate or ordinary rafter - forms a plane of a trapezoidal slope, the distance between them determines the run of the truss system;
sprig or short rafter - a structural element that is attached to a diagonal rafter, forming a triangular overhang and the corner parts of the trapezoid.
The calculation of the hip roof truss system is carried out taking into account the following prerequisites:
The calculation of the roofing material is carried out according to the formulas, taking into account the angle of the roof. Optimum roof slope for roofing materials different types shown in the table:
The slope of the slope angle determines the laying of the rafters. In turn, the laying of the intermediate rafter is calculated as follows:
The ratio between the length of the rafters and their laying is calculated using a correction factor, the value of which depends on the angle of inclination of the roof slope. The length of the rafter leg is determined by multiplying the laying by the coefficient.

To know how much to buy roofing material, you need to know total area roofs.
To do this, you need to break the entire roof into simple components. geometric figures and make a calculation for each of them.
The calculation of the hip roof area allows you to determine in advance not only the cost of purchasing roofing materials and installation, but also determine the requirements for materials, as well as the need for arrangement and the exact configuration of the crate.
The result of the development of the project and calculations will be a diagram-drawing of the hip roof truss system. There are no similar drawings ready for use without taking into account the features of a particular structure and the place of its construction.
The development of a preliminary scheme can be done independently (a simple sketch will determine the direction of the project). But, it is better to entrust the drawing to specialists or use special programs for calculation. It should be remembered that what harder design roof, the more accurately you need to calculate the truss system: configuration and materials. This will also affect the cost and duration of installation work.
The hip roof drawing should include an indication of the purpose of the material, its installation location and method of attachment. The key nodes of the hip roof truss system, for example, the adjoining of diagonal supports to the ridge beam or the installation of rafter legs on the Mauerlat, it is advisable to put them in a separate drawing and describe them in more detail.
Drawing of a hip roof (layered rafters with an emphasis on two runs)
Drawing of a hip roof truss system with a bay window
The presence of a schematic drawing will be a good help in the manufacture of blanks and subsequent installation of the roof.
The design of the roof and the methods of arranging the nodes determine the set of tools that should be prepared before starting work.
To work with wood, it is useful: a level, a hacksaw, a hammer, a tape measure, a marking cord, a stapler.
To work with metal structures you will need an electric drill, a riveter, cutting shears.
Tool and expendable materials must be prepared in advance, because complex installation hip roof truss system involves big number cuts and installation of nails.
To simplify measurements and be able to make all parts of the same size, the masters advise replacing the tape measure with a measuring rod. The measuring rail is made of plywood 50 mm wide, on which the main dimensions are applied.
The species and type of wood have a direct impact on the durability and reliability roof structure. Masters are advised to give preference to lumber or pine lumber. All blanks require pre-treatment flame retardants and antiseptics.
In addition to wood, you will need metal mounts, nails, self-tapping screws, anchor bolts.
Note. Forming a hip truss system on wooden house, which can shrink, the craftsmen advise using floating fasteners to connect the rafters to the Mauerlat. This method compensates for the movement of the crowns during the natural shrinkage of a house made of timber or logs.
Do-it-yourself truss system devices step by step:
This is the most difficult and time-consuming part of the construction, because. connected with:
In order not to buy different lumber, in practice the splicing (pairing) method is used edged board to get the given length.
Mauerlat for a hip roof is wooden beam large section (100x100 or 100x150 mm) mounted around the perimeter of the walls. For Mauerlat, wood of the first grade is used.
The peculiarity of laying the mauerlat is that the beam is connected along the length only with an overlap, but not butt, using a variety of connection points with the base of the wall. Connecting nodes additionally reinforced with metal staples.
Since the purpose of the Mauerlat is to serve as a support for the rafter legs, it needs to be protected from moisture. For this purpose, a hydrobarrier is laid between the wall and the beam (for example, roofing material is used).
Note. Under the Mauerlat brick houses(or from aerated concrete, foam concrete, wood concrete) a reinforced concrete belt is poured with pre-installed studs for mounting the beam. The hairpin has a diameter of 10 mm or more and should protrude beyond the Mauerlat plane by 20-30 mm. The installation step of the studs is 1000-1200 mm.
A run is a beam installed parallel to the sides of the Mauerlat. The run serves as the basis for the installation of additional supports under the rafter legs. The girder device is not obligatory step works and is performed only for hip roofs of a large area or having a configuration increased complexity. The location of the run is shown in the diagram.
It should be noted that the point of maximum load will vary depending on the location - on the ridge of the hip or on the edge of the valley.
Note. The hip hip roof is mounted without support, and a complex knot is formed at the junction of the diagonal rafters.
Racks perform the function of support when installing a ridge beam ( Orange color on the picture).
Installation of the hip roof ridge is accompanied by accurate measurements. Since the entire roof structure will rest on the ridge, the correctness of its installation is checked by height and level.

Regarding the sequence of work at this stage, the opinions of the masters differ. This makes it possible to single out two areas for work:
During installation lower part rafter legs rest on the Mauerlat.
The support of the rafters on the hip roof is shown in the diagram. The first option (with a notch) is simpler, but the second (with a support bar) is preferable, because. in this case, the fastening does not weaken the rafter.
The formation of a node on a ridge beam is possible in different ways.
Top mounting options for diagonal rafters are shown in the diagram.
Advice. For rigidity, it is advisable to reinforce all nodes with metal elements (brackets, plates, corners).
Since the diagonal rafters have a significant load, they can be strengthened using such means as:
Privates are installed similarly to the installation of the central rafters, which form the edges of the trapezoid. Their lower part rests and is attached to the Mauerlat, and the upper part rests against the ridge beam. It is important to observe the same distance between ordinary rafters.
Narozhniki are made only from solid lumber. At the junction of the sprig to the long rafter, cuts are made or installed support beams. The installation site is additionally reinforced with metal elements.
Note. The installation of the hip roof splices is possible in a run-up to simplify installation.
In any case, spawns are installed after formation power frame roofs. Their installation ends with the installation of the hip roof truss system.
The program shows the installation process of the truss system of a gable hip roof with a central bay window along a short wall.
After the rafter system is ready, you can proceed with the installation of the roofing, the specifics of the fastening of which determines the need for mounting the crate on the rafter legs.
Installation of a hip roof truss system is a lengthy process that requires attention to every stage of the work - from the calculation and selection of material, to the installation of parts and strengthening of attachment points. But, at correct execution all stages, the result will be a beautiful and reliable roof for a private house.
