Modular metal tile. Recommendations for the installation of modular tiles Installation of end strips and ridge

When roofing, the most difficult thing is to cover a complex roof. Here it is necessary to choose the right material. One of the best suitable options is a modular metal tile. Even one person can mount it on the roof of a complex configuration. And what are the other advantages of a modular metal tile, and what are the nuances of its use?

Material Features

Modular metal tile is gaining more and more popularity. Manufacturers offer many types of this modern roofing material. But, they all share one main feature. Modular metal tiles are not produced in sheets, the length of which sometimes reaches 6-8 meters, but in small modules, hence the name. For other characteristics, this type of roofing material does not differ from the same type.

The modular metal tile has the following positive qualities:

Ease of transport and storage. Modular metal tile Venice, namely this brand is considered the most popular, has a sheet width of a little more than a meter, and a little less length. Such small dimensions make it easy to transport and store the material;
Small dimensions speed up the installation of modular metal tiles. In addition, such small dimensions allow one person to work on laying roofing material, without the involvement of assistants;
A number of manufacturers, including the Venice brand, provide special grooves and protrusions on each module. This simplifies the "cohesion" of sheets of material and also speeds up installation;
Another important plus is waste minimization. When, especially if the roof is complex, there are always a lot of trimmings. This is due to the fact that you have to "customize" the pattern. In the case of a modular metal tile, such waste will be many times less. And this means that the financial costs will be less.

In addition, do not forget about the "usual" advantages of this type of roofing material. The metal tile is durable, strong and easy. Also, this material has an attractive appearance.

If we talk about the shortcomings, then he can be said to be the only one. Modular metal tile is quite expensive. Of course, a lot depends on the manufacturer. The better the material, the more expensive it is. For example, the Venice brand is considered expensive. But this minus is easily compensated by a long service life, practicality and attractive appearance.

Characteristics

Modular metal tiles are produced by several manufacturers. But the differences in the products themselves are minor. The most popular brand is Venice. Its characteristics are as follows:

The total width of one module is 1190 millimeters. This parameter is taken into account during transportation and storage.
The useful width of the sheet is 1150 millimeters. It is this value that should be taken into account when calculating the amount of material to cover the roof.
The height of the wave or profile is 26 millimeters. Such dimensions are sufficient to give the sheet the desired bending strength.
The length of the module is 736 millimeters. If we talk about the useful value of this parameter, then it is equal to 70 centimeters.
The size of one "tile" or wavelength is 35 centimeters. It is this value that is taken into account when choosing .
The area of the entire module is 0.8 square meters. Knowing this parameter, you can easily calculate the required amount of material to cover the roof. Just be sure to add 10-15 percent.

Another important characteristic is the weight of the module. It is 3.7 kilograms. It means that square meter roofing from a modular metal tile will weigh less than 4 kilograms.

What you need for installation

Laying a modular metal tile is not too different from the usual version of this roofing material. First you need to prepare everything necessary tools and fixtures. For installation you will need the following:

In addition, the modular metal tile itself should be prepared. Most manufacturers, to protect the polymer layer from damage during storage and transportation, cover it with a film. It needs to be torn off before.

Laying

Venice metal tile or another brand of this type of modular material is mounted in almost the same way as a regular one. But there are also some nuances. The installation itself is carried out in the following sequence:

Separate modules of metal roofing tiles are an innovative laying and fastening technology, and the brand "Venice" has become one of the most popular in the construction markets. What explains the popularity of this type of tile? What is so special about her?

Description

The module is a separate, completely finished piece that can be easily laid on any type of roof slope. Small in area and light, only one person can lay it, which is why the builders of private houses loved it so much.

The tile modules are made in one piece from sheet steel using Swedish technology, with a matte or glossy finish.

The product has a unique shape - five lower and six upper waves, and the unusual angle of the tiles helps during installation - the sheets lie perfectly evenly with excellent fit to each other over the entire roof area. The lower relief part of the wave only once again emphasizes the exclusivity of the shape of the Venice metal tile, it can be put on a par with the most exclusive types of ceramic roofing products.

The tile consists of:

High strength polymer layer;
Primers at the bottom of the zinc base
The product is covered with an anticorrosive layer of high-quality protective varnish.

Pros-cons

Features of the structure of the metal tile Venice is able to reliably protect the structure from various leaks without arranging an additional waterproofing layer. The appearance is very similar to the traditional ceramic tiles, so familiar to many, but its characteristics are far superior to it:

Not afraid of sunlight and does not suffer from a change in the original color;
The cost is very democratic;
Installation accessible even to a novice builder;
High strength and durability of products;
Not afraid of drops temperature regime;
Low weight of products;
The laid tile copes well with waterproofing;
Excellent view of the entire flooring and a variety of color shades.

Among other things, it is very economical and less waste is left during installation.

Particularly relevant are modular tiles for roofs with complex slopes, attics, or several at once. In such a house there are always several chimney pipes, which, with a different type of roofing material, are quite difficult to equip and waterproof. And smaller modules can be stacked to suit even the most complex roof design, and are easy to cut and fit to size.

Each sheet has special holes, with the help of which it is successfully attached and connected to other elements of the roofing material, the seam is practically invisible, which will undoubtedly affect the impermeability of moisture and raindrops. But for all these amenities, of course, you will have to pay much more than for simple sheets of cermet.

Take a closer look at the ceramolist of Venice - you will see a characteristic bend on it, this is not done by chance, this detail is designed to give the sheet special resistance to the onslaught of bad weather and all kinds of winds.

In addition, during roofing work and fitting parts, very little waste remains, they are cut without crumbs, solid parts remain, which can then be used to cover chimneys or other inaccessible places, there are many options for their use, and waste-free production, of course, can only be attributed to the positive qualities of cermets.

Installation instructions

Note! In flight with a metal tile, there should be a briefing on the main work, but if it is not, then you need to know:

All the necessary holes for fasteners are already present on the finished parts, you do not need to do anything yourself;
Small recesses ensure the invisibility of the seams of the joints;
All recesses are bowl-shaped, which acts as a waterproofing barrier, they prevent moisture from entering;
The unique front part creates conditions for ventilation, which will affect the life of the truss system.

On the video - a modular metal tile budmat Venice:

For high-quality installation, prepare special tools:

Electric scissors for cutting purposes;
Cordless screwdriver - if it is not there, then working with a long wire can complicate the work;
Ordinary construction scissors for cutting metal;
Special powerful stapler and hammer;
Level, marker and folding measures.

Step by step:

First you need to assemble the rafters, put the crates on them;
Cover the legs of the rafters with a septic tank and you can use construction foil:
The distance between the rails in rows - 290 mm, along the axis - 350;
Then auxiliary strips are attached in places of chimneys and sewage system;
After preparatory work finished, you can start laying metal tiles;
Lay the first part in the lower right corner, secure it thoroughly with fasteners;
The next product is placed along the end part of the previous sheet, self-tapping screws are placed in the finished holes and fastened;
In this technique, lay all the material, do not forget about the ridge and the drainage system.

You will also need to pick up parts for finishing the chimney, you can do this from the waste that remained from cutting the tiles.

For those who have made their choice and settled on the Monterrey metal tile, it is worth paying attention to the existing guest of this material, and for this it is worth going

What are the benefits soft roof in front of the metal tile exist and which of them are the most important, is described in detail here

What and how to choose the right building material for yourself is described in this article.

Modular tiles are relatively the new kind roofing. Its release began in 2010. The brands of European companies are in the greatest demand: Venecja, Talia and Germania (produced by different companies in Poland), Finnera (Finland). The obvious difference from conventional steel sheets is the smaller dimensions. Manufacturers have significantly improved the quality of the connections between the fragments, facilitated the installation process and extended the service life. Even one person can handle the installation, and the guarantee reaches 50 years.

Characteristics and properties

It is made from sheet steel with a thickness of 0.5-0.8 mm. Products are treated with several layers of protection: zinc and polymer decorative coating- from the front side, galvanized and varnished - from the inside. Fragments are interconnected by means of an additional bend on the upper and lower edges, due to this, absolute tightness is achieved. The mounting holes are already drilled at the factory.

There is a special type of modular tile - with a hidden mount. The fragments are connected by a Z-shaped lock, so that the screws are under the roofing sheet and are completely protected from atmospheric phenomena.

Finishing coatings are resistant to any external influences. They have a high class of protection against UV rays, they are not afraid of chemical compounds, sand, moisture, temperature changes. The difference in shades between products from different batches is strictly regulated, visual discrepancies in color are excluded.

Sizes vary slightly from manufacturer to manufacturer. Dimensions of tiles from BudMat:

width - 1190 mm (5 waves, 6 ridges);
height - 736 mm (2 rows);
usable area - 0.8 sq.m.;
weight of one module - 3.7 kg;
wave height - 26 mm.

The ridges are reinforced with stiffening ribs - they ensure the stability of the module to large wind and snow loads. Thanks to the lock-type joints, the finished roof is a monolithic structure without horizontal and vertical joints visible to the eye.

The most demanded metal tile on the construction market Venice from the manufacturer Budmat has three types of coatings:

X-Matt (thickness 30 microns) - matte, will last up to 50 years.
D-Matt (35 microns) - fine-grained matte, 30 years of service.
S-Pure - glossy, warranty period - 20 years.

The main differences between products from different manufacturers are in the shape of the wave, the number of stiffeners and the quality of the finish layer:

The combs of the Germania modules are reinforced with two vertical bends. Wide selection shades and textures.
Talia - without additional stiffeners. The polymeric compositions for staining are the same as those of the previous species.
Finnera - the shape of the wave resembles Venice, the crest is reinforced with one fold. Finish coat– Purex.

The tile is completed with additional elements: ridge strips, valleys, drainage systems. Transported to wooden pallets(Europallets) 350 pcs with foam pads for shape retention.

Benefits of a modular roof

Convenience. Even one person can handle the installation of a roof from small fragments with already prepared holes for self-tapping screws. They do not need to be customized, sizes with high precision factory calibrated.
Minimum waste. Suitable for multi-pitched, geometrically complex roofs, the number of non-working trims will be small.
Appearance. Waveform and most coatings mimic natural tiles. The houses look expensive, presentable and unique.
Tightness. A special system of connections and recesses in the area of fastenings provide reliable protection against leaks, both at vertical and horizontal joints.
Lifetime. No other material can boast a 30-50 year through hole guarantee. The appearance is preserved for up to 25-40 years, depending on the type of polymer composition.

The only downside is the high cost. It is justified by the fact that the products are different high level quality, are transported over long distances and are already maximally ready for installation, the builder only needs to fasten the fasteners. They do not have noise and heat insulation, but this problem can be easily solved by equipping the roofing cake with a layer of insulation.

Mounting Features

The installation of modular tiles is practically no different from other metal ones. sheet materials. There are some nuances:

The place of attachment to the crate is the lower point of the wave, the self-tapping screw is screwed in with a slight indent from the step of the next row. The frequency of the beam or board should be equal to the length of the stamping step. For BudMat, it is 35 cm.
As fasteners, it is necessary to use self-tapping screws with a press washer that are suitable in color. It is more convenient to screw them with a screwdriver. A screwdriver is acceptable, but the duration of work will increase significantly.
For cutting, it is better to use special metal scissors (manual or electric). Disc tools are not suitable as they damage the protective coating of the steel.

You will need a tape measure, a marker for marking, a building level. Before starting work, it is necessary to remove the protective film from the surface of the tiles, if any, and place the cornice drips and brackets under the gutters.

Installation steps:

The first fragment is placed in the lower right corner of the roof, fixed along the edge and in the middle of each wave of the first row under the threshold of the second tile.
The second module is placed to the left of the first, fixed with self-tapping screws.
The third is installed above the first, first the screws are screwed in the lock, then to the crate, thus the entire roof is sheathed.
Completion - installation of the ridge, valley, sealing of the openings of chimneys and chimneys, construction of gutters.

If the modules had to be cut, then the edge must be treated with paint to protect against moisture and rust formation.

Overview of the cost of shingles of popular brands

This material is different from other metal roofing long term service without loss appearance and attractive design. Original products have a laser or stamped marking.

Roof made of BudMat metal tiles with an area of 100 sq.m. it will cost at least 50 thousand rubles (only the cost is indicated, without extras and fasteners), but repairs will not be required for a long time. If one fragment is mechanically damaged, it can be replaced. To do this, it is not necessary to disassemble part of the structure, it is enough to unscrew only the damaged module and buy a new one in its place. A variety of shades and textures of coatings allows you to choose a material suitable for the exterior of the building, which will last for several decades.

STRUCTURE OF A METAL ROOF

CRATING

When ordering metal tiles along the length from the eaves to the ridge.

The crate is assembled from antiseptic-treated bars with a section of 50x50 mm and boards 32x100 (approximate dimensions). First, falling bars 50x50 (depending on the waterproofing used) are nailed to the rafters over the waterproofing from the ridge to the eaves, to which the sheathing boards are then horizontally attached. The distance from the beginning of the first board of the crate to the middle of the second board is 300 mm (for metal tiles with a pitch of 350 mm) or 350 (for metal tiles with a pitch of 400 mm). The distance between the middles of all other boards of the crate with a section of 32x100 is 350 mm (for a step of 350 mm) or 400 (for a step of 400 mm).

The first board from the cornice of the crate should be 10 - 26 mm higher than the rest, depending on the step length and the height of the metal tile step.

For example: if the step height is 26mm, then B1 = 58mm. (26mm + 32mm). B2- varies depending on the step length and step height.

The value of B2 is determined empirically.

Check the lengths of the roof slopes diagonally to make sure the roof is square. Take into account the minimum permissible angle when installing roofs from metal tiles 14۫. If the angle of inclination of the slope is less than 14۫, then the overlap of the sheets of metal tiles is done in two waves.
It is important to know! That on the inner surface of any roof there is condensation of moisture contained in the warm air rising from interior spaces. This leads to the formation of mold, moistening of the rafters and battens, freezing of the roof and damage. interior decoration. To deal with such phenomena it is necessary:

carry out thermal insulation of the interior from the roof;
protect the thermal insulation from below from moisture vapor barrier film, and on top with a waterproofing film;
provide good ventilation

INSTALLATION OF METAL SHEETS

When ordering a metal tile, it is necessary to take into account the length of the slope, if its size is more than 4 m, we strongly recommend ordering a metal tile in equal modules.

See Fig. 4. This will ensure the preservation of the geometric dimensions of the metal tile and ease of transportation and installation.

Installation of metal tiles without hidden fastening

metal tile without concealed fastening you need to start from the lower right corner, when the next sheet covers the previous one. The optimal stacking order of sheets is shown in Figure 4.

The slope angle of the slope of the metal tile should be at least 14-17 degrees.

No matter how difficult the slope is, the sheets are laid parallel to the eaves, aligned strictly horizontally.

Several adjacent sheets are fastened with one self-tapping screw in the upper half of the sheet, aligned and then finally fixed. Average consumption of roofing screws-6-8 pcs. per m2 and 4 pcs. per linear meter of accessories. For screwing self-tapping screws, it is best to use a screwdriver or drill at a low rotational speed of the cartridge.

Example

Fig 4.

Fig 5.

The general rules for fastening metal tiles without hidden fastening are as follows:

The metal tile is always attached to the lower crest of the wave at the point of contact with the crate. With this method of attachment, there is no lever between the attachment point and the point of application of forces to the self-tapping screw.
The lower sheets are screwed over the step at the points of contact with the crate in each wave, at the points of contact of the overlaps, since the greatest wind loads fall on this edge (Fig. 5).
Self-tapping screws are attached as close as possible to the bottom of the step. Firstly, in this place the metal tile has the greatest rigidity, Secondly, these places are usually in the shadow falling from the step, and the heads of the screws are not so noticeable.
On the side of the end plank, the metal tile is fastened at each step of the wave. (node 2, figure 5)
In places of vertical overlaps, the metal tile is fastened at each step of the wave of the covering and covering sheet at the points of contact with the crate (node 1, Fig. 5).

Recently, metal tiles have been increasingly used for arranging the roofing part. The material is supplied in the form of profiled sheets with a polymer coating. If desired, you can independently perform the installation of metal tiles. Step-by-step instructions will help you do this without serious mistakes.

Works on laying fragments of roofing

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

Enumeration of merits

First of all, it is necessary to highlight the following advantages:

aesthetic appeal;
weather resistance;
affordable cost;
lightness of the main elements.

Note! Polymer coatings perform not only a protective, but also a decorative function, since their color range can vary over a fairly wide range.

A few shortcomings

Since the sheets have a small thickness with sufficiently large dimensions, there is still a risk of damage to them during careless installation. Subject to all the rules, the integrity of the elements is difficult to violate.

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

Assembly tools

In advance, you need to prepare a set of tools and accessories for work:

Note! It is forbidden to cut sheets using abrasive wheels, as high temperature exposure leads to the destruction of not only the polymer, but also the zinc layer.

Basic set of additional parts

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 configuration of the roof and operational features.

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

a skate is required to close the upper joint between two slopes;
the end plank is necessary to decorate the edges from the side of the gable overhangs;
the valley is installed at the places where the slopes coincide;
the eaves plank is attached from the side of the gutters;
the junction bar is mounted in the presence of a pipe and other protruding structures;
a snow retaining element is needed to prevent snow from sliding off the roof.

Installation instructions for metal tiles: step-by-step execution of work

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

Waterproofing device and fixation of control bars

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

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

Proper installation of the crate under the metal tile

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

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

Installation of parts mounted up to sheets

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

When installing the valley, a universal seal is laid. The bottom edge of the element should be on the surface of the cornice board. At the junction horizontally, an overlap of at least 30 cm is made.

Stroking a brick chimney implies the withdrawal of a waterproofing membrane by at least 50 mm. A strobe is made in the pipe itself, the depth of which should be at least 15 mm. Water is diverted to a valley located in the immediate vicinity.

The process of laying and fastening sheets

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

the self-tapping screw must be installed in the deflection of the wave, where the sheet is adjacent to the crate;
fastening to the bottom board is carried out above the step directly through the wave;
along the edge of the slope, fasteners are screwed into each wave.

Installation of end strips and ridge

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

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

Additional instructions for installing snow guards on metal tiles

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