A metal tile is a universal material that is mounted on any roof surface. It is resistant to precipitation, high humidity, temperature extremes. It is possible to carry out work with such material as metal tiles in all regions of Russia.
Modern roofing is a multilayer structure. Roofing cake for flexible tiles consists of lathing, waterproofing, roofing, thermal protection and additional elements. If the "roofing cake" is properly installed, then this will allow the roofing to be used for many years.
The specific multi-layer system performs many protective functions:
- protects against the penetration of steam from the room - insulation;
- keeps the house cool in summer and warm in winter;
- protects the wooden parts of the roof from the process of decay;
- prevents the formation of condensate in the thickness of the roof.
An important point in the device "roofing cake" is the choice of materials.

Elements of the roof structure for flexible tiles:
- rafter system;
- insulation;
- vapor barrier with connecting tape;
- waterproofing;
- crate;
- counter-lattice;
- roofing;
- additional elements;
- roof ventilation system;
- snow holder;
- drains;
- filing of the cornice overhang.
The metal tile roof pie includes several insulating layers, which have an important function in protecting the entire house from the negative effects of cold, moisture, and noise.
For roofing from this material, two types of cake are used: for insulated and non-insulated roofs. The insulated roof provides the building with a warm attic, which allows you to equip it with a living space.
Advice!
The roof structure should be designed so that, regardless of the weight of the roofing material, it can withstand a load of up to 200 kilograms per 1 sq.m.
As a heater, only those materials that have high vapor permeability should be used. Mineral wool materials have this property.
After installation, the insulation must be covered with a vapor barrier film. Also in the roofing pie, a good air flow should be organized in ventilated gaps.
Roofing from a metal tile
Roofing under metal tiles appeared in Finland more than 30 years ago, but it became known on the Russian market only recently.
Your attention!
The device of a roof from a metal tile begins with preparatory work which includes measurement, the order and delivery of roofing material. When using metal tiles, a slope of 14% should be adhered to.
After the preparatory work, the rafters and battens are installed. At lathing installation antiseptic boards should be used.
On the underside of the roof, the battens are laid on top of the rafters with waterproofing material to ensure ventilation.
Then carry out the installation of the roofing. Installation starts from the left and right ends of the roof. First, the first sheet is installed and attached with one screw, and the second is laid in exactly the same way as the first - the lower edges must be laid strictly in one line.
After installing all the rows, the ridge with a sealing gasket is fixed and the roof is closed with ridge elements.
It is recommended to install a sealing profile gasket, which is attached to the crate between the ridge and sheets of metal. The ridge bar should be installed strictly along the cord, the pitch of the screws is 20-30 cm.
Metal roofing is the most correct solution for pitched roofs. It is used both for high-rise buildings, and for cottages and private houses, as well as for major repairs of buildings. To make an accurate calculation of the roof of a metal tile, you can use the services of a measurer for this.
Calculation of the cost of materials for roofing
An estimate for a roof made of metal tiles should be carried out immediately before construction and installation work.
The estimate is a document that consists of the cost of all ongoing construction work and installation.
It is also necessary to carry out a detailed analysis of the roof before starting work, that is, take into account all the materials and work that will be carried out. Next, you should write a defective act, on the basis of which an estimate for the construction of the roof will be drawn up.
Modern roofing is a rather complex structure.
For example, a flexible tile pie consists of insulation, roofing, wind protection, vapor barrier film.
These details should also be displayed in the estimate.
When restoring the roof, an estimate is also drawn up for the repair of a roof made of metal tiles, which takes into account all the costs incurred and calculates the necessary material.
Considering such a design as a roof made of metal, the technical characteristics of the material, its advantages and disadvantages must be described at least briefly.
Advantages:
- light weight, which avoids additional work to strengthen the truss system;
- due to the properties of the coating, they have a rich color gamut;
- ease of installation and fire safety;
- long service life - 50 years.
Flaws:
- high thermal conductivity;
- the need for regular painting of the coating;
- low sound insulation;
- susceptibility to mechanical damage;
- the need to install a lightning rod.
Peculiarities:
- A metal tile roof is suitable for absolutely any roof, in which the angle of inclination is at least 10 degrees.
- The material is not intended for horizontal roofs.
- The polymer coating can be matte and glossy.
- The coating has good resistance to sunlight and aggressive environments.
Installation of metal sheets is carried out using a special tool, and it is carried out only with an overlap.
On the crest of the wave there are special recesses to protect the joints.
Attach this material to the crate using self-tapping screws.
The material can be completed with skates, gutters, and necessary additional elements.
This type of roof fits perfectly into any landscape and can be used in any region. In most cases, it is produced in red, but recently gray shades and shades of ultramarine have become popular.
