What should be the step of the roofing for metal roofing?

If you decide to use metal roofing material as a covering material, it will be necessary to carefully study the technology of the installation works, and not only the roofing itself, but also the system of the lathing.

Peculiarities of calculation

The step of the flooring under the metal tile should be selected with a look at some factors. Among them, we can distinguish the variety of roofing, it is important to pay attention to its profile. It is necessary to take into account the step between the arrangement of neighboring elements, which, as a rule, is indicated in the instruction by the manufacturer of the material. In order to determine this parameter, it is necessary to measure the distance from the bottom edge of the first board to the upper edge of the second one. The step of the roofing under the metal tile will depend on the slope of the ramp as well as the width of the roof protrusion beyond the start bar of the system.

The master must decide before the work starts, whether the design will contain a drain, as this affects the calculations. If the gutter is fixed to the frontal board, then you need to add 30 millimeters to the ledge. Among other things, the gutter for the gutter, or rather its diameter, will play a role. Thus, if its value is equivalent to 90 millimeters, the projection will be different from the case in which it is equal to 120 millimeters. Measurement of the parameters of the protrusion of the roofing material should be made from the frontal board, while the slope of the slope will depend on how much the metal tile should be released. If you make a mistake, it can adversely affect the determination of the correct location of the crate. At this position of the roof, the material will not coincide with the elements of the dredging system.

Determining the distance between elements

The step of the roofing under the metal tile should be determined taking into account the availability of the valleys, while measuring the parameters and making the fastening of the trolley from top to bottom, given the length of the tail of the system. In a number of cases, due to the presence of a long tail, there is a need for mounting an additional board of the dredging system, which is necessary for rigid fixation of the ridge's bar.

Features of fastening

Before starting work, you should think about what step of the roofing for metal tile will be chosen. It is also important what materials will be used. Thus, for rafters, a bar with a cross-section of 150 x 150 mm should be used, which is the minimum value, but a 25 x 100 mm beam should be used for the wire. It is important to install not only the crate, but also the control bar, for it you need to use a board with a cross section of 25 x 50 millimeters. The distance between the rafters should vary from 600 to 900 millimeters. The first board should be located in a straight line along the eaves, while you should not allow it to be strengthened with a ledge.

Advice of a specialist

The step of the roofing under the metal tile should be chosen in such a way that the distance from the board projecting beyond the cornice to the next element is less by 50 millimeters compared to the rest, that is, this parameter should be equal to 300 or 400 millimeters. The distance between the following components of the crate should be equal to the step between the nearest upper points of the profile, that is, 350 and 450 millimeters. The step between the boards of the trolley should be equivalent to 350 millimeters, with the exception of this rule being the first and second boards. To analyze how correctly the distance between the first elements is determined, it is still necessary on the ground. To do this, parallel to each other, two blanks should be placed at a certain distance, you can bait them on the crate itself. Then they impose a tile on the tiles, which will determine the most suitable length of the projection of the roofing.

Possible mistakes

If the step of the bog was incorrectly determined and the ledge turned out to be too long, this will cause the water to pour over the edge of the chute, while with a short ledge the water will flow between the chute and the frontal board. With a long ledge, the sheet can deform under the weight of the snow. To perform markup, you should use a tape measure. Afterwards, it is necessary to fix the end and skate straps. The wind bar should be located above the crate. In order to easier to strengthen the skate, in the right place, you need to fix additional boards measuring 25 x 100 millimeters.

Summarizing

As you know, the most difficult to determine the distance between the elements of the frame system. What should be the step of the roofing for metal roofing, you must know, because otherwise the roof system will not be reliable. For the reason that fixing a sheet of roofing material is recommended in the lowest part of its wave, the distance between the components of the lathing must be selected depending on the step of the material profile. As the optimal and standard dimensions of the transverse wave of metal tiles, 300 and 450 millimeters protrude. When calculating the distance between the boards of the battens, you should be guided precisely by this indicator.

Features of the execution of the wire

The step of the crate for the metal tile "Monterrey" will be the same as for the traditional material. Before making the work, it is necessary to measure the distance between the rafters. Thus, the length of the board or bar, which will form the basis of the crate, will be equal to the index, which is a multiple of the distance between the rafters. Select wood for the system is necessary so that it is well dried in natural conditions, as well as thoroughly impregnated with antiseptic. In addition, the elements can be treated independently with flame retardants. Depending on the configuration of the system, a plank of 24 x 100 millimeters should be used as a material for the crate with a roof slope of 15 to 60 degrees. The pitch between the rafters should be 1200 mm. A board of 36 x 100 millimeters should be used if the distance between the rafters exceeds 1200 millimeters. This is also true for the case where a metal tile with a thickness of 1.5 millimeters is used.

When the step of the lathing under the metal tile "Grand Line" (or any other) is determined, you can proceed to purchase the materials. Thus, if the roof has a non-standard configuration, then use bars 40 x 60 millimeters. At the same rafters will be stacked with a significant step. The cladding can be solid, while using chipboard or plywood. This material is combined with a crate made of a bar. This statement is true for complex areas of the roof, for example, areas of abutment, cornices, ridge or hills. Calculation of the step of the battens for metal tiles is made using the same technology if it is intended to use a metal profile that is capable of replacing wooden elements. This solution is worthwhile when there is a need to achieve high fireproof properties of the roofing system.

Determination of quantity of material

If you strengthen the crate under the metal, do the right step, it's very important. But it is also necessary to calculate the amount of materials. To do this, the number of rows in the lattice must be multiplied by the number of boards in the row, and then by two more. In the end, you get the right amount of lumber, which should be purchased to perform the dredging. Due to the fact that sawn timber is sold, as a rule, in volumes, the number of boards must be converted into cubic meters. For this, the geometric dimensions, expressed in meters, must be multiplied, and then multiplied by the number of boards determined by the calculation. The material is preferable to purchase with a certain margin, which will be necessary in the event that some elements are defective. If it is a question of a roof of a complex configuration, the calculation should be carried out for each section of the system separately.

Finally

You can determine the step of the crate by reading the article, but this is only a small part of the success. It will also be important to carry out the installation work properly, following the technology. Only in this way the calculations will be justified, and the entire system will differ in strength and durability, as well as in an attractive view.
