Roofing made of metal today is the most popular in private and even capital construction. Use it not only in the process of installing new roofs, but also for the renovation of old ones. Moreover, in most cases, the use of metal roofs is resorted even to the external cladding of balcony fences and small frame structures.
In general, the field of application of metal tile is quite extensive - they are used almost everywhere. And all this is due to the mass of benefits that this material provides.

Advantages and disadvantages of a roof from metal tiles
It should be noted immediately that this roof still has more advantages:
- Firstly, it is a wide range of products of various sizes and colors. Not to please even the most demanding customer, she simply can not.
- Secondly, it is not subject to the harmful effects of aggressive weather conditions. The paint does not burn out, and the material itself does not collapse even in severe heat or frost - as a rule, the lifetime of a roof made of metal tiles is estimated at five to six decades.
- Third, the low weight of this roofing material allows you to reduce the cost of installing the roof truss system of such a roof.
- Fourthly, this is an easy installation - if you have certain knowledge of the technology of its device and some specialized tool, you can make a roof of metal roof yourself.
- Well, fifth, thanks to its low weight, the roof of the roof can be made with metal roofing directly over the old coating. Only for this purpose it is necessary to be convinced of reliability of an old rafter system.
The lack of metal roofing almost does not have - they can be attributed only to its noise and a lot of subtleties and nuances of installation work. It's not a secret for anyone that during rain the roof made of metal tiles becomes a kind of resonator that amplifies the sound of rain drops falling on it - it is with this nuance that most of the technological features of mounting such a roof are connected.

How to calculate a material for metal roofing
Basically, calculation of a roof from metal tile is business artless enough. All you need to know for this is the size of each individual slope( length and width), the length of the outer and inner mates( ends and skates) and the moldings of the cornices. It is these dimensions that determine the amount of material required.
Let's start with metal. Most manufacturers produce this roof covering in four sizes. The width of the sheets is usually the same( 1160mm), and the length is measured in waves. Standard sheets are metal in 10 waves, 6, 3 and 1 wave, which corresponds to 3620mm, 2220mm, 1170mm and 470mm. What is the size of the slope of your roof? If it is not more than 450mm, then you need to buy a single-wave sheet, if not more than 970mm - three-wave, respectively, if it is within 2 meters, then a six-wave one and if its length does not exceed 3.4m, then a ten-wave one. In general, you need to give a reserve for the overhang of the roof and pick up the metal with the required number of waves.
The number of sheets is calculated based on the length of the roof slope - here it is necessary to take into account the fact that the sheets are laid with overlapping. If the actual width of the metal tile sheet is 1116 mm, its effective width( without overlapping) is slightly less, and is 1100 mm. It is at this size that you need to divide the length of the slope of your roof to get the required number of sheets.
You may need to combine the types of metal tiles - in most cases, the length of a sheet of ten waves is not enough to fully cover the entire width of the slope. For example, to cover a roof slope with a metal tile 4 m wide, it is better to use two sheets with a length of 6 waves each - their total size in akkurat enough for both the overlap and overhang.
Calculate the number of endes, skates and cornices of labor does not amount to - for these purposes only roulette will be needed. But we should not forget about overlapping the material with each other - the minimum overlap should be 100mm. Therefore, translating linear meters into the number of products, their total length should be divided not into the actual size of these parts, but into useful ones.

How to install roofing from metal tiles
Installation of roofing from metal tile is quite simple. If you have the patience, knowledge and the necessary tools, this work may seem even interesting.
The most important thing is that you do not have to rush anywhere and all the work should be carried out exactly as required by the technology of the roof of metal. For this purpose manufacturers have developed five installation rules:
- In order to protect the roof from the influence of the side wind, the sheets of metal tiles should dock exclusively on waves with overlapping on each other. When stamping sheets, it should be remembered that their fastening is performed by screws screwed into the crest of the wave of the top sheet below the punching line. First of all, the longitudinal joints of the sheets are strengthened.
- Along the rows, docking of sheets occurs simultaneously with fixing them to the crate - you need to fix each wave.
- An important point that provides for the roofing of metal roofing is the fastening of sheets on the cornices:
- First, the sheet of metal should extend beyond the cornice at least 50mm,
- Secondly, the cornice board should be thicker used for the crate at 1-1,5cm.
- Third, the screws must be screwed six to seven centimeters above the punching line through each wave.
- No less important moment of installation of the roof from metal tiles is the skate device. As in the case with cornice, the sub-fin board should be thicker than all the other boards of the crate by 1-1.5 cm. This thickness difference is designed to provide ventilation of the under-roof space. Attracted metal tile to this board self-tapping in steps of at least 80cm and they are installed in the crest of the wave.
- Well, the last thing you need to know, wondering how to make a roof of metal roofing is the fastening of sheets on the ends of the skates. Here it is necessary simultaneously to strengthen not only the edges of the metal tile, but also the end plates. On the plane of the roof, self-tapping screws are installed through the wave, and to the gable board every 80 cm.

How much does the roofing of the metal tile
Want to know how much the roof is made of metal? Its cost can not be calculated based only on the roof area. Prices for installation work depend, first of all, on the type of roof and its complexity. On the assessment of the cost of the roof a considerable influence is exerted by the material itself. It is for these reasons that the calculation of the cost of metal roofs is carried out on an individual basis. On average, the cost of laying the metal tile varies from $ 100 and higher per one square meter. But the cost of the metal is not high - depending on the manufacturer and the material used, the square meter of this profiled metal can cost from $ 15 and above.
