Metal is today one of the most versatile roofing materials.It is produced in the form of sheets of galvanized steel: the raw material is specially treated to obtain the effect of simulating natural tile, and the surface is treated with a polymer coating different colors.This type of roofing material has good technical characteristics, such as low weight sheets, strength and durability, the ease and speed of installation.Consider the question of how to close the roof metal tile in detail.
Preparations
Before installation you must carry out the preparatory work, which constitute the gasket and sealing assembly batten roof system, as well as the calculation of the required amount of material.
Waterproofing
for roofing coating of metal, usually on the inside of the condensed moisture, which eventually leads to undesirable consequences, such as corrosion, rotting roof rafters and others. To do this, carry out the works on waterproofing and layinginternal ventilation.On the question of how to close the roof metal tile, this phase plays an important role.Below is information that could be helpful:
- Waterproofing lay overlapping starting from the eaves upwards, while the apex leave a gap of more than 50 mm to create air channels.
- Carpet waterproofing materials are laid on the joists or rafters, while it is necessary to strengthen the system battens.
- Vents must be provided at the highest point of the roof.
- in unheated attics create natural ventilation - end window, if necessary inserted into the means for forced air circulation.
assembly of battens
to more fully disclose the issue of how to cover the roof, look at the highlights of the assembly of battens.To perform the crates must use solid boards, pre-treating them with antiseptic.Recommended size - 30 × 100 mm.Installation of the boards is carried out with a certain step, the value of which is indicated in the instructions included in the kit.This interval corresponds to a step wave on the sheets.
Laying bars begin from the bottom edge, with the very first bar should be greater thickness of the remaining elements in the 1-1.5 cm crates. The boards are fixed across the roof beams using screws.Plan a mechanical bar above batten to the height of the wave crest fixed to the rafters with nails made of galvanized steel.For durable installation ridge strips provide additional boards.Planck cornice must be attached to the installation of tiles.Crate in the valley, around chimneys and skylights must be to lay a solid layer.
Calculation of raw materials
To understand how close the roof metal tile, it is necessary to take into account that the implementation of the calculation of the number of sheets of material is carried out separately for each slope, and consists of the following stages:
1. It is necessary to checksymmetrical rays by measuring them on the diagonal - these values should be equal.
2. Then, count the number of rows of roofing slope.To do this, measure the length of the roof slope of the valley to the eaves.This value should be divided into a useful indicator of the width of which is determined by deducting from the actual width of the sheet metal values overlap.The result should be rounded to whole numbers in the direction of greater magnitude.Typically, the tiles produced wide range 1,17-1,2 m, while the working value will be the same - 1.1 m, and the residue is used in the packing of overlap.For example, the ramp length of 7 m calculation will be carried out as follows: 7 m ÷ 1,1 m = 6,36 ≈ 7 series.
3. Further, the calculation is carried out in a number of sheets to determine the overall length of the sheets by adding the value of the length of the slope, the descent of the cornice and values overlap.It is recognized that the tiles are available with a maximum length of 8 m and the total length of the roof slope with a descent does not exceed this value, the value of overlap is equal to 0. However, transportation and installation of bulky material is difficult, such as sheets require cutting.If drop wave to coincide with the line of tiles cut, it can lead to undesirable consequences, for example, to deformation or difficulties during assembly.To avoid such situations, you need to choose the optimal length of the sheets.For example, if the ramp length of 6 m length and 0.5 m overhang can be installed on two sheets of a length of 4 m, with overlap - 0.25 m.
4. The total number of tiled sheets determined by the number of rows and the number of sheets in a row:7 rows × 2 sheets = 14 sheets on one skate.
Tools Required
also the question of how to close the roof metal tile, no harm will be information about the tools used.When installation work fitting the roofing material.This may require the following tools:
- Special device for cutting tiles made of metal.
- Hammer.
- screwdriver.
- line.
- marker.
As a special tool for cutting sheets is recommended to use jigsaws, metal saw with the teeth of pobedita, scissors and other tools.It is important to remember that the use of cutting tools with abrasive wheels made of, for example, saws, grinders, are excluded.This is so that the resulting high temperature can destroy the coating of polymer and galvanized, which would entail corrosion and degradation at the molecular level.
Installation of metal roofing
After preparatory work to begin assembling material.It should take into account the important points:
- sheet metal asymmetric, as they have a top and bottom, so the masonry material consumption increases.
- roof with two slopes veiled, since the end face, and the type of roof tent on both sides with the highest points.
- Overlap the sheets lengthwise envisage equal to 250 mm.
- At the edge of the eaves do plummet 40 mm.
- Metal tile is attached with screws to the depth of the wave at each meter cover must be 8 pieces of connecting elements.
coating of metal roofing is very economical because the installation work, shingles is not so complicated.Today the market of construction materials can be found various roofing materials, the prices of which are presented in a wide range.It may be noted that metal is the most inexpensive and suitable for most variants of the structure material.Proper selection and installation will help to keep your home from any weather troubles.
