In contrast to sheet roofing materials for the correct calculation of the number flexible tile It is enough to know the area of \u200b\u200bthe roof, because on each package roofing material The number of square is indicated. Meters overlapped area. Dobly elements are calculated by analogy with. Consider on specific examples how to determine the number of bitumen material and its components. The instruction is relevant for any manufacturers of bituminous roof: Shinglace, spraying, tagola and others.
Components of flexible tiles: Purpose and calculation
Before the start of the calculation of the roof, we will understand in the appointment of challenges of flexible tile. The names and types of components for flexible tiles are slightly different from the elements of the metal tile finish, but in general they have similar applications.
W. soft roof Metal strips are also used for decoration: wind, cornice (drip), plane adjoining. They have a somewhat different form, but by destination are similar to good metal roofs. Consider the most common of them.
Presented Dobly Elements bituminous Tiles Have a standard length - 2 meters. To calculate metal slats, it is necessary for the total length to which one or another apron will be installed divide by 1.9 meters (Useful length of each plank, taking into account the overlap).
Names and dimensions of metal slats may differ slightly.
The most important element in the device of a soft roof is lining carpet. It consists of bitumen and is an additional waterproofing of the roof in case of damage to the main roofing. The bituminous material is stacked throughout the roof area to moisture-resistant OSB plates (OSP - oriented chipboard) or moisture-resistant phaneur thickness of at least 9mm. The lining carpet is mounted horizontally, from the bottom up with overlap 100-150 mm.
In the case of the roof design with inner corners of the rods, the special place is stacked for these places endalous carpet. As well as the lining it comes in the form of a roll, but the material itself is thicker and has different color variations corresponding to the tone of the flexible tile. Endow is one of the most vulnerable places in the roof, so you should not neglect such material. The omene carpet lays along the entire length of the crossing of the roof rods.
The lining carpet is calculated on the basis of the roof area with a small margin (about 10%) on the twist. The carpet for the endand must be considered based on its length. If the length of the endand is equal to 10m, then the carpet needs to be purchased with a length of 10 route meters.
The above materials are the main components necessary for the roof device from the flexible tile. Additional elements may be needed in the case of complex roof forms.
Additional accessories for bitumen tiles
For a bituminous roof, in contrast to the tiled counterpart, it is made of durable plastic, has a special gap for air ventilation under the roof and foam inserts as a barrier from atmospheric precipitation or insects.
Ventilated tile flexible Over such plastic accessory fastened the ski tile.
Alternative to the skate valve are roofing Aerators or KTV-valves. There are various forms, but the principle of operation is similar - ventilation of the underpants space to prevent the formation of dampness and mold in roofing Piece, So, protection wooden design and OSP (OSB) plates and the entire design of the roofing system.
Different kinds Roofing aerators With a large length of the skate (more than 10m), designed from the top to the lower point of the roof, it is necessary to install both Ventkones and aerators. Otherwise, the undercase ventilation will not work properly.
To protect against penetration under the roof of insects or birds across the cornice zone is established mosquito net.
VENT Tape PVC It can be made of aluminum or plastic ( ventilation tape PVC). The element is attached by conventional wood screws. When installing flexible tile, many neglect this element despite its low cost, which can further lead to unpleasant consequences.
Calculation of snowstores for a soft roof
To prevent avalanche snow removal, it is recommended to install snowmaders (Snow walls). For flexible tile, a special design is used in the form of a small hook. Elements are installed in a checker manner and are attached to wood screws in special holes on the plate.
For bituminous tiles, it is necessary to install a snowstand system at the moment of installation of the roof, since part of the element is started under the tile sheet.
Snowswoman Flexible Tile To find out how many snowstores are needed in the case of a soft roof we use the rule: on the rods with a slope of 30 - 40 degrees, snow walls are installed at the bottom of the roof - 4 pcs. on 1 p meter, and when the roof is biased from 40 to 70 degrees - 6 pcs. per 1 mp
Snowflower installation scheme Calculation of flexible tiles for a bone roof
To calculate the amount of soft roofing for a row roof, you need to know the size of the roof rods. In this case, each slope will be a rectangle with the sides of a \u003d 10 m, b \u003d 6 m.
Dimensions duscal roof
Attention! For quick calculations we offer to use our.
According to the formula S \u003d A * B, calculate the area of \u200b\u200beach slope. If the rods are the same, as in our example, the area of \u200b\u200bthe roof we obtain SCR. \u003d 2 * A * B \u003d 2 * 10 * 6 \u003d 120 sq.m. Flexible tile must be purchased with a small margin (about 5%), thus the amount of roof for a bone roof is obtained in an amount of 126 sq.m. OSP plate or moisture-resistant fane believe for the same area. In the case of a lining carpet, add 10 kV more. meters for overlapping.
Universal formula for determining the number of packs of soft bitumen roofs for a simple roof design: Squeezes * 1,05 / Platakovka
Approximate calculation bituminous mastic - 5 liters by 60 - 70 square meters. meters of roof. For our area we get about 10 liters.
Now we will proceed to the calculation of components and accessories. Depending on the manufacturer skink-rose tile There is a different overlap length, but most producers have one packaging overlap 12 ending meters of the skate and 20 pound. meters of cornice. For our sizes, the length of the cornice part is 20 meters (10 meters on each side), i.e. 1 package. Plus another bundle for the skate, the length of which is 10 pounds. meters. Total we get the packaging "Konk / cornice" in the amount of 2 pieces.
It should be noted that for laminated (two or three-layer tiles) there is no need to purchase a cornice tile, since the lower rectangular layer of the roof is already performing its function.
Ventilated Konk you consider the formula: the length of the skate / length of the vent. skate. That is, 10 m divide on the length of the vent. Skate (each manufacturer has dimensions different). For such a bartal roof of the skate fans, it will be enough. If the roof has an area more, you need to add additional aerators - one aerator is about 40 square meters. meters.
Metal strips have a standard length - 2 meters. Number of wind (frontal) S5 slats Calculate by formula: 24/19 \u003d 13 pcs., Where 24 is a total length where wind aprons (6m x 4) are installed, and 1.9m - the useful length of each plank, taking into account the overlap .
The cornice bar (S1 and S27) is calculated in the same way. 20/19 \u003d 11 pcs. In this embodiment, there are no roof adjoins with a wall or chimney, but the calculation will be produced by the same formula.
Aluminum mosquito net or PVC tape is mounted in the cornice area, so their length will be equal to in our case 20 of the route meters.
The procedure for calculating roofing nails is as follows: 0.5 kg per 10 kV. meters of roof (or 4 pcs. on the sheet). For the sizes presented about 6 - 7 kg.
Let's summarize the calculation in the table:
Example of calculating a soft roof for a four-tie hip roof
For a holm roof, the calculation of the amount of flexible tiles is made in the same way. First of all, we learn the area of \u200b\u200bthe roof and, adding 5-7%, we obtain the amount of soft roof. We also consider OSB (OSP) and lining carpet.
Dimensions of a holm roof The roof consists of two trapeziums and two triangles. Square of the trapezium We consider the formula:
Stage. \u003d (A + B) * Crop. / 2 \u003d (3 + 12) * 5/2 \u003d 37.5 sq.m
The area of \u200b\u200bthe triangle is equal to:
STREUG. \u003d D * HTREUG. / 2 \u003d 10 * 4/2 \u003d 20 sq.m
Folding all the squares, we get the area of \u200b\u200bthe roof of 115 sq.m. For the roof, take about 123 square meters with a small stock. meters, and for a lining carpet - 135 sq.m.
The skate-carnice elements will be larger due to the presence of not only the top of the skate, but also side ribs. In the lower part throughout the perimeter also stacked "Konk / cornice" with the exception of the laminated roof. We obtain that the shelter of the skate will require length 4 * C + a \u003d 35 meters (3 packs), and for eaves 2 * b + 2 * d \u003d 44 meters (3 packs). VENT Horse count only on the upper (horizontal) part of the edge. For proper ventilation of air under the roof, add 6 aerators: 2 pieces per trapezoidal skates and one per triangular.
The second difference from the duplex is the lack of wind slats, but the amount of cornice aprons is added throughout the perimeter of the roof: 44/19 \u003d 24 pcs.
We also need a little more mastic and nails for sealing the skunk tiles and its attachments. Otherwise, the calculations of the soft roof are no different from those described above. In completion, also give a table with the indicators of the required amount of flexible tiles and components.
IMPORTANT: The roof measurement should be made as accurately as possible!
We hope the article turned out to be useful and answered questions how to calculate the flexible tile on the roof without the help of online calculators. It should be noted that the process of determining the number of bitumen roofs should always be carried out independently, since special resources mainly offer a surface result, without taking into account additional accessories and stock material.
The correct calculation of the soft roof is not the easiest task, but before choosing the roof material, I want to have an idea of \u200b\u200bthe cost, at least at least approximately. Consider what you need to consider and what features should be taken into account so that the calculation is more accurate.
Features when calculating
There is such a thing as a departure, and it is not going anywhere, inevitably part of the material will be cut, it can be corrupted, etc., so it is necessary to calculate the material for the roof is necessary with a margin.
Tiles usually indicate tolerances on "surplus", which are expressed as a percentage, but these are standard roofs, so you need to take into account your profile of your roof, because if it is complex, waste may be more.
If the roof is double, we accept the rectangle area, where the sides are the width of the sink and the dual length of the skate.
Example of calculation required material For simple.
It is a clean area and such material as plywood or lining carpet, practically correspond to this area with a small reserve of 3-4%.
For example, the roof area has 50 m2. The area of \u200b\u200bthe plywood sheet is 1.25x1.25 \u003d 1.57, it means that we need 50 / 1.57 \u003d 32 sheets. But! The plywood sheet also has its size and it is necessary to calculate in such a way that the sheets of 1.25 m width fit as possible into the width of the roof, since the overhang can be increased or decreased (which might also be needed when calculating tiles, both soft and metal tiles, eg). At the same time, we recommend varying the length of the sweep from the area of \u200b\u200bthe most expensive material, because, most likely the price soft tile There will be more than plywood.
The area of \u200b\u200bsoft tiles, as a rule, is indicated in any price list, and this is a pure coating area, due to the characteristics of the laying (with overlapping), the actual area of \u200b\u200bthe tile will be greater.
For example, the packaging area is 3.5 m2, which means we will need 50 / 3.5 \u003d 14.2 packaging, and duscate roof Experience no more than 3-4%, so we will buy 15. If the sheets are not spoiled, the material is enough.
The calculation of the lining carpet is easier, it is a clean roof area, taking into account the ribbon width, and, as a rule, you can buy trim so as not to take an extra whole roll. The calculation is almost completed, it remains to add a skate element, it is the length of the skate, fold the resulting amounts and you can get an approximate view of the order of the roof value.
Difficulties begin if the roof has a more complex profile, so we will try to calculate the double-circuit roof with a separate skate in the middle and slopes of a complex shape, since the house has erkers.
How to calculate a complex profile
So, we have in terms of the roof of 8 triangles, four trapezoids, two trapezoids, whose vertex and base are not parallel, and two rectangles. Clean area is 258 m2. The roof is covered with plywood, waterproofing, lining carpet (100%), with a final layer of soft tiles from above.
- Plywood. Considering the complexity of the profile, we accept the overrun for 10% and we get 258 / 1.57 \u003d 165 +16 \u003d 181 sheet.
- Waterproofing We consider the clean area, and since it is sold in a roll, you will have to add one roll. The amount is not specified, since different manufacturers offer different widths and total roll area.
- Lining carpet (lining for soft tiles). The calculation is based on the basis of 5% of waste just in case, understanding that we can spend less material. With dimensions of 1x20m, we will need 258/20 \u003d 13 rolls, we will not take more into account more.
Now - calculation of soft tiles.
Based on the packaging area of \u200b\u200b3.5 m2, we obtain in the clean size of 258/3,5 \u003d 74 packaging. Understanding that the profile is very complex, with many overlaps, solve add 10% and obtain 81.44 (or 82 packaging).
Next, we calculate the Mongon Metage of Skate Elements, taking into account the fact that on bends in the area of \u200b\u200btriangles, they should also be installed (if angle is less than 120 degrees). Here, while we still limit the length of these elements, taking so much so as not to buy extra. In our case, taking into account the profile of the roof it turned out 78 route meters.
Will not forget that the roof has internal anglesThis means, we will need Endov. Soft material that will be laid in such angles. Here you also limit ourselves to the rode, in our case 51 m.
The profile of this roof is that we will not need additional items, like wind protection, because the sinks will be linked by siding, and on the edges of the sink it is planned to install the waterproof system. However, we will need 3 meters to protect the protruding edges in two places. Since standard 2 m, you will have to buy two strips.
What did we do? Plywood 181 sheet (1.25 per 1.25 m), 258 m2 waterproofing, 13 rolls of lining carpet 1 to 20m, 82 packing soft tiles (3,5m2 each), 78 pm Skates, 51 pm UNDOVOM and 4 m wind strip.
These data can already go to the store, find out the price of the material to calculate the approximate cost of the roof. Just in case, the obtained value is better to increase by 3-4%, then the calculation will be more accurate.
What happened in the end of the calculation
And now interesting Facts. The fact is that the real roof was considered. The preliminary calculation on it was precisely in the form in which sets out. But since the roof is ready, there are these actual costs of materials.
- plywood took 192 sheets, because in sharp corners of unequal triangles without loss of quality coverage, it did not work out and the material had to be purchased;
- waterproofing 285 m2, since complex beggars were decided to block for the reliability of the brass;
- the skate elements were used 84 pm, partially also with overlap;
- lining carpet 12 rolls, because Part of the area was closed by UNDOVA;
- endovism consumption amounted to 48 pm;
- wind strip 3 m;
- soft tiles of 85 packages, because the sheets had to be cropped on complex bends, and it was impossible to use the remnants.
However, taking into account the preliminary data, in value terms, the price of the roof was + 7% of the initial calculation, and the error (if adding 4%, which was mentioned) in 3% allows (taking into account the amount) to calculate the coming costs.
Online Roof Calculator Designed for the rapid and ultra-precise calculation of the number of required materials for roofing any kind of roofs. Enjoy this program. One condition is necessary - should be more or less in geometry.
It should be noted that this calculator is exclusive - it is positioned as a soft roof calculator and is intended for calculating the flexible tiles of shinglas and related materials.
Before the immediate start of the calculation, the program proposes to choose the roof type. Developers offer four types: single, duplex, hip and attic.
Selecting the roof type, a new window opens - select the size of the roof. The program takes into account all the nuances: the width and length of the roof, the length of the eaves and the frontal soles (and on both sides of the roof), the angle of slope. The last nuance is very important. Indeed, depending on the corner of the skate, both in relation to each other and in relation to the base, the flow rate of the required material during the roof can be significantly different. With uncertainty in choosing an angle, the program has provided the "The angle of the slope of the slope is not known."
To find out the area of \u200b\u200bthe roof, you should enter the necessary dimensions in meters. It is necessary to know that if the length of the front-bottom sweep is assumed, for example, 30 centimeters, then you need to enter a decimal value, that is, 0.3.
Entering all the necessary data, the program proposes to make calculations for additional indicators. The consumer is provided with calculations for visors (single and bounce), accounting mansard windows and pipe-chimneys. Entering numbers occurs in a similar way, as in the previous program submenus.
After that, it remains to choose the form "Calculation". To calculate the required number of materials online, the roof calculator spends the fraction of seconds. The next and final stage: the program offers how to do further. You can immediately look at the list, you can save it in the two proposed formats (to choose from) - Exel or PDF. Also, for convenience, it is proposed to print a list immediately after the calculation.
The indisputable advantage of this calculator is its accuracy. In the proposed list, all materials for the roof of the roof of the specified size are taken into account, their number is fed in certain units of measure (pieces, rolls, kilograms, robes, packaging, etc.).
For additional questions, if such an all the same arises, the developers are thought out with the manufacturer. The consumer directly from the Calculator pages can send an email with questions or wishes and is guaranteed to get an answer in the shortest possible time.
