Arched roof - how to make an arched roof with your own hands

Modern private house building is famous for the fact that it has a large arsenal of technical solutions, allowing to make the external and internal appearance of the house the way the customer wants to see it. This proposition is also true for the choice of the roof construction, therefore in the cities more original arch-type roofs replaced the traditional dual-pitch, hip or hip roof.

The arched roof is an elegant, lightweight, ergonomic design that immediately makes the architectural appearance of the house more original, more interesting, bolder. But the most important thing is that this option of arrangement of the roof will cost no more than the standard, if you understand its device with your own hands.

Device and its advantages

The roof of the arched type is a curved-shaped structure in the form of an arc, with the help of which they block residential houses, industrial or administrative buildings in order to protect them from precipitation, cold and wind. Previously it was thought that this constructive solution is more suitable for buildings with a specific purpose - swimming pools, greenhouses, greenhouses, shopping galleries and transitions. But now the arched roofs are actively used in the construction of private houses, due to the following advantages:

1. Original appearance. A house with a quaint curved roof immediately visually stands out from the same type of buildings with a flat or dvukhskatnuyu roof.
2. Resistance to wind loads. The aerodynamic, curved shape without sharp corners makes the arched roof invulnerable to strong gusts of wind, which often lead to breaks in the roofing.
3. Reducing snow load. The arch, which has a curved shape, does not hold snow masses on the slope, due to which the load on the supports and the foundation decreases.
4. Increase the volume of the room. Due to the arched roof structure, the internal volume of the house increases, because of which it becomes visually more spacious, larger.

Note! Depending on the configuration, roofing material, arched roofs can give the house both an old, historical look, and an ultramodern, up-to-date look.

Support frames

Many inexperienced developers are wondering how to properly make an arched roof of an arched type. For a start, it is important to understand that the roof frame is the most important part of the design that performs the bearing and distribution functions, ensuring its reliability and stability. For the device of the roof in the form of an arch use the following types of frame:

• Wooden. The wood frame is a simple but effective solution for the arched roof of a private house. It is cheap enough and convenient for installation, but it is not designed for heavy weight, and therefore not suitable for roofs with a large area.
• Steel. The frame made of square steel pipes is a solid, reliable basis for the installation of an arched roof, however, this is a rather massive option that requires the installation of the foundation and walls with high load bearing capacity.
• Aluminum. The arched frame made of aluminum is highly resistant to corrosion, light in weight, has a good bearing capacity. In addition, standard profiles can be easily assembled even with your own hands. The only drawback of this option is the high price.
• Reinforced concrete. Reinforced concrete arched structures for roof installation are produced, but they are used only in the construction of industrial, commercial or sports facilities with a large area.
• Frameless. For the assembly of arched roofs, a special self-supporting corrugated flooring of a curved shape is produced, the assembly of which is carried out without arranging an additional supporting frame.

Important! The correct calculation of the frame structure is a guarantee of strength, reliability, durability of the structure. Calculations of the required bearing capacity are made in accordance with the climatic conditions, slope and other roof parameters, taking into account the weight of the roofing material.

Types of coatings

Before you build a house with an arched roof, you need to consider that not all roofing materials are suitable for this construction. The coating for the arch should be easy to bend, keep its shape well, so the choice is very limited. The most common materials for ceiling arched roofs professional masters believe:

1. Sheet steel. Roofing steel sheets are often used to overlap an arched roof type. They are cheap enough, easy to install and maintain, however, they have a low carrying capacity.
2. Decking. Special arched corrugated specially designed for arched roofs. It has a high bearing capacity, which gives it a reinforced profile, but it weighs a little. Arch profiled available with a standard bend radius.
3. Cellular polycarbonate. Another solution for the roof of the arched type is cellular polycarbonate, which has a translucency of 80-90%. This property of the roofing material in combination with a very low weight and high strength allows you to maximize the opportunities of natural lighting in the building.

Note that the possible form of an arched roof depends on the selected roofing. The maximum bending radius has a cellular polycarbonate, which is most often used to overlap structures of this shape. In addition, this material is simply mounted using special profiles, and also weighs little.

Arched polycarbonate roofing

Translucent roof of light but durable polycarbonate is a popular technological solution for greenhouses, greenhouses, shopping pavilions, gazebos or other elements of urban infrastructure. Installation of such structures is performed according to the following algorithm:

• Before you make a roof-arch, it is necessary to calculate the bearing capacity of the frame and the optimal distance between the elements.
• Further, according to the calculation and the drawing, the frame is made of a light aluminum profile. It is important that each arc should have the same shape. To do this, first use the template.
• The arc of the frame is fixed on the top trim of the house in increments of 1-1.5 meters. First, the first and last construction trusses are installed, and all the others are already aligned with them.
• With the help of fixing strips on the farms, cellular polycarbonate is attached, not forgetting to take into account the gaps for thermal expansion of materials.
• The ends of the polycarbonate cell protect from moisture and dust penetration with a special end profile.

Remember that cellular polycarbonate must be laid so that its profile is located along the bend of the arch, otherwise condensate will accumulate in the honeycomb, which can not get out of it.
