Pros and cons of roofing material

The products are based on a steel sheet with a thickness of 0.45-0.55 mm. It is galvanized and has a special polymer-based coating. The cost of production may vary depending on the thickness of the metal and the type of protective layer.

List of advantages

First of all, the following advantages must be highlighted:

Wide design possibilities are provided by a variety of profiles and colors

Few disadvantages

Since the sheets are thin and large enough, there is still a risk of damaging them if they are carelessly installed. Subject to all the rules, the integrity of the elements is difficult to break.

In order not to break the sheets when lifting, it is recommended to use bars

Another disadvantage is the appearance of a noise effect during heavy rain during operation. However, with the correct soundproofing living space this disadvantage is completely eliminated.

Basic set of accessories

In the step-by-step instructions for the installation of metal tiles, the main elements used in conjunction with the sheets should be mentioned. They are used depending on the roof configuration and operational characteristics.

The main elements of the roofing are presented

It is suggested to take a look at the list of basic parts:

Loading and unloading of products can be carried out manually, but during the work a certain number of people must be involved. Usually 1 person is required for 1.5-2 linear meters of sheet length. That is, when unloading metal fragments 6 m long, 3-4 people must be present.

Waterproofing and fixation of control bars

If thermal insulation is laid between the rafters, then the waterproofing material must be present in any case. It is fastened with brackets to the supporting part of the roof. The canvases are spread across the rafter legs with an overlap of at least 15 cm along all slopes.

Laying waterproofing under the crate

Bars 50x50 mm are nailed directly along the rafters, providing a ventilation gap between the waterproofing and the roofing material. For fixation, nails of at least 90 mm are used.

Correct installation of the lathing under the metal tile

An edged board 25 mm thick and 100 mm wide is usually used as a lathing, but the final choice will depend on the pitch of the rafters. The elements are attached to 50x50 mm bars using nails at least 70 mm long. The distance between the boards depends on the wavelength of the metal tile used.

The step of the lathing of popular types of metal tiles

In the place where the ridge element is installed, it is recommended to install two strips close to each other. This will simplify the installation of the ridge on the metal tile. The same should be done in the places where the valleys are attached. The bottom board of the sheathing should be higher than the rest by the height of the wave. Usually the thickness of the lining is sufficient to compensate for the difference.

The battens are ready for roofing

Installation of parts mounted before sheets

To protect the ventilated space under the roof from the penetration of moisture and street debris, the eaves of metal tiles are being installed. An additional ventilation tape must be attached to the ends of the 50x50 mm bars.

The eaves plank is fixed to the lathing

When installing the valley, the universal seal is laid. The bottom edge of the element should be on the surface of the eaves.At the horizontal joint, an overlap of at least 30 cm is made.

Brick outline chimney implies the withdrawal of the waterproofing membrane by at least 50 mm. A groove is made in the pipe itself, the depth of which should be at least 15 mm. Water is discharged into a valley located in the immediate vicinity.

The process of laying and fixing sheets

All sheets must be aligned horizontally with a 50 mm crate outlet. When fixing metal elements, the following points should be adhered to:

Layout and fixation of sheets

Installation of end plates and ridge

Elements for closing end joints are mounted in the direction from the eaves overhang to the ridge. The overlap on adjacent strips should be 10 cm.The recommended spacing between the fasteners is 35 cm.

The side edge of the sheets is closed with an end plate

As for the ridge, it is fixed in the upper crest of every second wave. When building up the elements, a gap of at least 15 cm is left. A self-adhesive sealing tape is attached along the entire length.

The location of the seal directly under the ridge

Additional instructions for the installation of snow guards on metal tiles

The number of elements for holding snow drifts on the roof is selected taking into account the geometry of the roof. In areas of heavy snow removal, two rows of metal profiles can be installed. Through-type snow stoppers are the optimal solution for individual buildings. They are attached using long self-tapping screws to the crate itself through roof... The distance between the fixation points usually ranges from 50-100 cm.

Snow guards are located along the edge of the slopes

Ordering metal roofing: prices for installation work

If you hire specialists, you will have to spend additional funds. The price for installation of metal tiles per m2 is presented in the table.
