Today, more and more developers, instead of heavy clay tiles or modest slate, use a durable, light and very strong metal tile. The house covered with it looks very presentable and elegant. When buying this roof, you should pay attention that the metal tile sheet size can have different (both in length and in width). In this article we will give the most common dimensions, as well as tell you how to accurately calculate the consumption of material.

What you need to know about the width and length of metal tile sheets
Distinguish between full and useful length and width, and, accordingly, the area of sheets of metal. To determine the full length of the sheet, you need to measure the distance from one edge to the other. The full width, which depends on the width of the steel sheet rolls, is measured in the same way.
The length can range from 40 centimeters to 8 meters, and the width can range from 1.16 to 1.19 meters. It is convenient to use a sheet corresponding to the size of the roof, but only when it is not too large. And then, after all, a six-meter panel is not so simple to pull up and mount, and the walls can be pretty torn off. So the optimal size of the sheet of metal for the roof is the width - from 1.16 to 1.19 meters, and the length is 4.5 meters, not more.
When one sheet of roofing is partially superimposed on an adjacent sheet, the place of their overlap is called an overlap, or overlap. This eliminates leaks and increases the strength of the roof. Full width and length minus overlaps and will give usable length and width, as well as sheet area. For a metal tile, the overlap in width is quite small - only from 6 to 8 centimeters. In the longitudinal direction, it will be slightly larger - from 10 to 15 centimeters. Having thrown back these sizes, it is possible to calculate the useful area of the sheet of metal tile, and, accordingly, to calculate the required amount of material. The amount of overlap will depend on the manufacturer of the metal tile.
Other important parameters of metal tiles:
- Sheet thickness: 0.45-0.5 millimeters (the most popular is the last value). When buying, it is better to check whether the thickness declared by the manufacturer is true. And it happens that in reality the roof is thinner than in the material passport. It is harder to transport a thin roof, and it is capricious in installation, and can withstand smaller loads.
- Profile height: 1.8-2.5 centimeters and depends on the type of profile. Other sizes are possible in the manufacture of metal tiles to order.
- Profile wave step: 35-40 centimeters. If necessary, it is also possible to order a roof with a different wave step from the manufacturer.

Installation dimensioning
Before installation, calculate the area of the roof. Measure the length of the cornice and slope, and depending on the results obtained, select the appropriate sheet size. If the dimensions of the metal roof tiles do not fit into its configuration, you can always cut off the excess. Buying short sheets is also not entirely profitable, because there will be a large overspending of material due to overlap.Therefore, the length of the sheet should be optimal depending on the length of the roof slopes.
Consider some important points:
- For the crate, only boards treated with antiseptic are taken, so be sure to observe the center distance (35 and 40 centimeters).
- The board facing the cornice is thicker than other boards by a centimeter and a half.
- Due to the overlap, part of the width and length of the sheets of the metal roof is lost. Therefore, when buying a metal tile, always round the calculated amount up.
What you need to know about additional elements
For installation, in addition to the metal itself, standard components, the so-called additional elements, are also used. For example, the length of the ridge is usually 2 meters. The wind profile has the same size. However, here it is necessary to take into account the overlap, so in reality the length of the elements will be reduced to 1.9 meters. Thus, the number of skates required for installation is determined as follows. The length of the slope of the roof is divided by 1.9 (the true length of the ridge), and then round off the resulting value in the direction of increase.
Now we will do the same with the wind profile. Only by 1.9 we will divide the total length of the ends. We have 4 of them, each of 4 meters - in the end we get 16 meters. Divide 16 by 1.9, and then round to get 9 pieces. So, we need to purchase 9 standard wind profiles.
But these are not all additional elements. We will also need the details necessary to retain the snow (after all, the metal tile is slippery, and snow can leave it in an avalanche). It should also include strips for the eaves, and some other elements, depending on the configuration of the roof.
