The roof of the metal: the calculation and installation features

metal roofing is now the most popular in the private and even the capital construction. use it not only in the installation of new roofs, and for reconstruction of the old ones.Moreover, in most cases, have resorted to the use of metal even at the outer skin of balcony railings and small frame buildings.

In general, the scope of the metal is quite extensive - make it almost everywhere.And all this thanks to the weight of the benefits offered by this material.

Advantages and roof disadvantages of metal

Immediately it should be noted that the advantages of this roof still has more:

• Firstly, it is arange of products of various sizes and colors.Not to please even the most demanding customer, it simply can not.
• Secondly, it is not subject to harmful influence of aggressive weather conditions.The paint does not fade, and the material is not destroyed even with extreme heat or cold - as a rule, the term of service of the roof of metal estimated five or six decades.
• Third, the low weight of the roofing material can reduce the installation costs of such a roof truss system.
• Fourth, it is easy to install - in the presence of certain knowledge of its technology unit and a specialized tool roof of metal can be done independently.
• And fifth, thanks to its low weight of the roof metal tile roof can be made directly over the old coating.Only for this purpose it is necessary to ensure the reliability of the old roof system.

disadvantages metallocherepichnoy roof practically does not have - for them it is only noise and a lot of the subtleties and nuances of installation works can be attributed.It's no secret that when it rains the roof of the metal becomes a kind of resonator, which amplifies the sound of falling rain drops on it - with this nuance and is associated most of the technological features of the installation of such a roof.

How to calculate the material for the roof metallocherepichnoy

In principle, the calculation of the roof of metal - it is quite unsophisticated.All you need to know this, it's the size of each individual ramp (length and width), the length of the external and internal interfaces (valleys and skates) and planed moldings.These dimensions and determine the amount of material needed.

begin with metal.Most manufacturers produce this roofing in four sizes.The width of the sheet is usually the same (1160mm), and the length measured in wavelengths.Are standard metal sheets in 10 waves, 6, 3 and 1 in the 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, it is necessary to acquire the single-wave sheet, if not more than 970mm - respectively three-wave if it is within 2 meters, then shestivolnovy and if it is not more than 3,4m, it desyativolnovy.In general, you need to stock up on the overhang of the roof and pick up metal roofing with the necessary number of waves.

number of sheets is calculated from the length of the roof - here it is necessary to take into account the fact that the sheets are stacked overlap.If the actual width of the metal sheet is 1116mm, its effective width (without overlap) is slightly smaller and is 1100mm.It is at this size is necessary to divide the length of the slope of your roof to get the required number of sheets.

may need to be combined with various metal - in most cases the length of the sheet in ten waves are not enough to completely cover the entire width of the ramp.For example, to cover the roof slope metal tile width 4m, it is better to use two sheets of a length of 6 waves each - their total size in exactly enough and overlap, and overhang.

Calculate the number of valleys, skates and labor eaves will not be - only tape is needed for these purposes.But here, we should not forget about the overlap of material together - the minimum overlap should be 100 mm.Therefore, translating running meters in the number of products, their total length should be divided not on the actual size of these components, and useful.

As mounted the roof of metal

Mounting roof of metal - it is quite simple.If you have patience, knowledge and necessary tool, this work may even seem interesting.

Most importantly - do not have to hurry and all work should be carried out exactly as required by the technology of metal roofing.This is why manufacturers have developed five rules of installation:

1. To protect the roof from exposure to crosswinds, metal sheets should be joined only by the waves overlapping each other.Stykuya sheets, it must be remembered that their fixing is carried out with screws, screwed into the crest of the waves below the top sheet stamping line.Primarily strengthens the longitudinal joints sheets.
2. the ranks docked sheets occurs simultaneously with fastening them to the crate - it is necessary to fix each wave.
3. important point, which provides for roofing of metal, is mounting sheets at the eaves:

• Firstly, the metal sheet should extend beyond the cornice at least 50mm,
• Secondly, cornice boards should be thicker than used for crateson 1-1,5sm.
• Thirdly, it is necessary to fasten the screws at a distance of six or seven centimeters above the punching through every wave.

1. No less important point of installation of the roof is a metal device skate.As in the case of the cornice, podkonkovaya board should be thicker than the rest of the boards lathing on 1-1,5sm.This difference of thickness is designed to provide ventilation of roof space.Attracts metal to the board with screws with a pitch of not less than 80cm, and set them in the crest of the wave.
2. And the last thing that you need to know, wondering how to make the roof of the metal - it's fixing sheets at the ends of ramps.Here it is necessary at the same time to strengthen not only the edge of the metal, but also the end plate.On the plane of the roof screws are installed through a wave, and to the board of the gable every 80cm.

How much does the roof of metal

Want to know how much of metal roofing?Its value can not be calculated based only on the roof area.Installation work rates depend primarily on the type and complexity of the roof.In the assessment of the cost of the roof has a great influence and the material itself.It is for these reasons, costing metallocherepichnoy roof is carried out individually.On average, the cost of works on installation of metal ranges from $ 100 and above per square meter.But the cost of the metal is low - depending on the manufacturer and the material used, the square meter of the profiled metal can cost anywhere from $ 15 and above.
