Standard metal sheets for roof trim
Useful sheet size should match the size of the roof, but not be too large, otherwise the roof installation process can be considerably more complicated. The most convenient for installation is considered 1.16 m width and length -. 4.5 m It should be borne in mind that the sheets of material are assembled overlapped, i.e. the edge of one sheet is superimposed on neighbor. This is done in order to eliminate the possibility of leaks and increase service life of the coating.
The optimal size for a metal roof - a full size minus excesses. In standard cases overlap size is from 6 to 8 cm in the transverse direction and from 10 to 15 - in the longitudinal direction. Also, the value of laps depends on the brand of your chosen material.
What parameters should be considered in addition to sheet metal size
In addition to the length and width of the sheet of roofing material, must be considered when selecting a number of important parameters:
- sheet thickness. This parameter varies from 0.45 to 0.5 mm, most popular is the latest version. The thickness is indicated in the parameters that are stated by the manufacturer, but it is better when buying check it manually. If the purchase is too thin metal roofingThen it will be difficult to transport and install, and the load it can survive a little;
Parameters and dimensions of the sheet metal
- profile height. The standard height is 1.8-2.5 cm, if you need a sheet of greater or lesser height, its production can be ordered individually;
- step wave. For standard models ranging from 35 to 40 cm, but the order may be made with profiles of other characteristics.
The most popular among buyers enjoy the metal with a small wave height - up to 50 mm. This is due to the fact that it is cheaper than other types of profiles and easier to install. If the wave height exceeds 50 mm, these sheets are considered elite and are more expensive than usual.
Useful advice!Wave profile can also be asymmetrical or symmetrical. The first variant is more common and cheaper. The sheets are produced with symmetrical wave is not all manufacturers and are several times more expensive.

Dependence of the size and price of sheet metal on the characteristics of the models
One of the features of the material - is the presence of sheets explicit top and bottom. This means that they can not turn over. If your roof is a complicated form, and you use for roofing tiles complex configuration, this feature largely complicates the installation and increases the cost due to the large number of waste.
If you choose a model with a complex wave patterns, it is necessary to understand that it is not just going to be more expensive than the standard, but also its installation takes you more time and effort. Therefore, if you do not have professional skills in the field of roofing, better to stay on the simpler and cheaper option. Photos roof of metal shows that it looks good even when mounted the most common roofing material with no frills.
If you want to understand how it will look already edited material on your roof, you should visit the dedicated stands, where manufacturers show has already finished pieces of the roof.
The variety of metal colors
Features and purpose of the various layers of material
When selecting the size of the sheet metal roof is necessary to consider that the material itself is composed of several layers, each of which has its own special purpose:
- Zinc layer - metal sheets protect against corrosion, humidity, and other types of adverse effects;
- polymeric layer - the sheet material gives the desired coloration, acts as an additional protection against external influences. In the photo the color of metal depends precisely on top of the polymer coating.
- a passivation layer - does not accumulate on the sheets of roofing material to static electricity;
- Primers layer - is the basis for applying the polymer coating.
When choosing a roofing material is coated, you receive a guarantee of longevity of 10-15 years, and with the right mounting and care for a longer period of time.
Dimensions of the sheet metal roof: the price and features of various coatings
Common sizes of sheet metal are summarized in the table below:
| The size (length x width) in mm | Overlap in length, mm | Overlap width, mm |
| 705h1190 | 45 | 5 |
| 3600/2200/1150 / 450h1185 | 100 | 85 |
| 3620/2220/1170 / 470h1140 | 120 | 90 |

Different roofing materials used to create the top layer of tiles of different materials:
- pural - a relatively new variant of the coating based on polyurethane. With a thickness of 50 microns, the material boasts high level of resistance to temperature changes, mechanical stress and corrosion. Tiles coated with from pura generally used in cases where the roof has to withstand very high or very low temperatures;
- polyester - a polyester based on glossy paint, characterized by a 25 .mu.m thick. Of its advantages can be identified stable, saturated color that does not fade in the sun, and the possibility of installation and operation in any environment. Furthermore, different polyester coating metal lowest price per square meter;
- matt polyester - the same as the previous embodiment, but differs slightly matte and gloss greater thickness - 35 micrometers. Also color stability is characterized by the fact that maintains a high level of performance in all environmental conditions. If you choose between matte and glossy metal tile - which is better, the choice here depends entirely on your individual preferences in terms of the design of the roof;
As fasteners screws used for metal
- PVDF - gloss coating comprised of 80% polyvinyl fluoride and 20% acrylic. Its thickness is 27 microns, but the main advantage is the high level of resistance to UV and aggressive environments. Tiles coated with such good use when installing a house roof, for example, at the seaside. In addition, the coating of PVDF is samoomyvayuschimsya, and it can be installed not only on the roof, but also on the walls. Most often metal produced in the color so coated metallic and boasts color fastness and durability;
- plastisol - the thickest option polymer coating has a thickness of 200 microns. At the core material is PVC, and its main advantage - the highest compared to other levels of resistance to mechanical and atmospheric influences. The only drawback plastisol - when heated, it can fade and fade, so when installed in a hot climate it is recommended to use light-colored sheets.
Useful advice! The main criterion for selecting a polymer coating sheets embodiment - is the environmental conditions.

Types of roof slopes and their impact on the size of the sheet metal
The choice of metal for the roof size also affects the type of ramp. It can be as follows:
- mono- or gable roof;
- gable;
- hipped;
- Roof;
- hipped.
Various methods styling of sheet metal
Shed option - the most simple in terms of design and is characterized by the smallest of details. There is no pent roof ridge, additional ventilation elements and other spare parts, respectively, based on The single metal type roof can calculate the minimum waste. In addition, it affects the price of the work.
How much is covered with metal roof pent form? Much cheaper than other roofing options. But the durability of a roof is on top, even if you use the most subtle option, as the load on the shed roof is less than no roof other configuration.
For a gable roof is also suitable metal sheets of standard size. With a gable roof made of metal photos of houses look very attractive regardless of the manufacturer of roofing material or type of polymer coating. For thrift in terms of material used is an option a little more expensive than in the case of pent roof, but also does not require large financial costs.
For lathing devices are used boards 100 mm thick
hip roof - one of the most complicated and costly in terms of the use of roofing materials roofing options. What is the best metal roofing use in this case is up to you, but it is necessary to take into account the the fact that a sufficiently large amount of material can go to waste due to the complex configuration design.
Installation of a roof of metal
Regardless of sheet sizes, price per sheet of metal, assembling the roof of this material is carried out in a certain sequence and with observance of a number of important nuances.
Preparatory work
Once you have decided on a metal tile - what better to choose for the roof, you need to ensure the evenness of the surface of the roof. All detected defects should be eliminated, otherwise you run the risk of a short-lived construction with low quality water and heat insulation and other performance characteristics.
Metal roofing and apply for new construction and renovation
After all the defects of the roof will be removed, it is necessary to make measurements of each of the rays and the entire roof as a whole. It depends on the size and price of metal.
Useful advice! Metal tiles as roofing material should be selected if the roof pitch is not less than 14 degrees. Otherwise it is recommended to give preference to other materials.
If the roof is already some kind of roof covering, then it must be removed. Also, before starting the work necessary to bring through the roof all the alleged ventilation, chimney and other penetrations. It is not recommended to carry out the installation of the material in parallel with the tiling.
Sheets of the standard size of metal need be laid overlapping 10 cm. If the ramp is longer than 6-7 m, the sheet should be divided into 2-3 parts.
Installation of sheet can be carried out with any edge
the groundworks
Crate - is the foundation of the roof of metal. Its installation should be carried out in accordance with the following guidelines:
- Step between rafters must not exceed 900 mm. When using metal standard size is recommended to take a cross-section of the rafters 150h50 mm boards - 100h25 mm.
- First board should be nailed crates strictly along the eaves. Thus it must not protrude beyond the ledge, and its thickness should be 10-15 mm larger than the other system boards.

Construction of additional elements
Is a mandatory element roof cornice strip and wind, horse, gutter or other additional structural elements. Price skate for metal and other elements depending on your choice of manufacturer and model, and the installation of these elements includes some nuances.
On either side of the ridge must arrive extra batten boards, it will provide greater reliability of its fastening with any amount of metal working.
Wind board must be secured above the plane of the batten to a value which is the height of the sheet. This parameter, as well as the size of the waves of metal, depends entirely on the manufacturer. The answer to the question, what manufacturer of metal is best to choose depends on your financial capabilities and aesthetic preferences.
tin gutter may be used for roofs of metal
In order to equip the drain before the stacked roof deck to the bottom board crates need to attach special brackets, which will then be mounted trough. The optimal distance between the brackets - 50-60 mm and the trough slope - 5 mm per meter.
Cutting sheet metal and styling
Sheets of material are cut with special chopping eletronozhnits. It is not recommended to use for this grinder, since the sheet surface at the incision overheated, which leads to deformation and delamination of the protective layer.
Useful advice!If you plan to laying tiles on the roof with a complex configuration, the sheets to be cut is better to hire a qualified person, as you will reduce the amount of waste to a minimum.
The choice of colors and shapes of metal are purely individual factors
Laying should start with the edge of a slope, on the right end of the roof. Mounts should always carry in the hollows between the waves, and in places of overlapping sheets mount done in each groove. Thus it is necessary to take into account the size of the sheet. For example, the dimensions metallocheerpitsy Monterrey fit the definition of a standard and do not require special efforts for installation.
The photo metal roof color and styling always look perfect, but in reality in order to achieve this effect it is necessary to apply a considerable amount of effort. This includes not only the proper installation, but also the choice of the size and sheet model.
