Installation of elements of the roofing system (eaves strips). Frontal and eaves drip strip for metal roofing. Cornice drip strip

When making eaves strips for metal tiles, it is necessary to use a material similar to the roofing covering. The main structural element in it is galvanized steel, with a thickness of 0.4 - 0.5 mm.

Cornice strip used for metal roofing can be said to be a very important element. Indeed, thanks to this component, it improves not only decorative look roof, but it also performs a protective function.

We install the eaves strip after all the metal tiles have been laid and secured to the sheathing. But in some cases, it is fixed before laying the metal tiles.

Thanks to its oblong shape, it can protect not only the front eaves board from moisture, but also protects the space under the roof from moisture.

Installation of curtain rod

In order to install the curtain rod, the first thing we need to do is secure the fascia board. It is fixed to the ends of the rafters using galvanized nails. But there is also Alternative option– fastening the cornice boards in the grooves on the rafter system.

Then we proceed to filing, using a tongue-and-groove board or corrugated sheeting. We fix a support beam to the wall surface, which will serve as an additional support for filing the eaves overhang.

Before we begin installing it, we can also install brackets for the drainage system. Then we begin to install the cornice strip itself. And as was said earlier, if necessary, this can be done before the process of laying metal tiles begins.

The plank can also be mounted on top of the gutter fastening, using self-tapping screws or by screwing it into the eaves or front board. We leave a distance of 30–35 cm between the screws. When extending the plank, do not forget about an overlap of 5–10 cm.

Mounting features

We fix the eaves strip above the height of the wave of the tiles; at the same time, it should also be located above the level of the sheathing. We completely cover the corner of the roof end. We install fasteners on the top and sides. Thanks to the screws located on top, the strip is fixed to the crests of the tile waves.

After fixing, a joint is formed between the roof covering and the plank, which is carefully sealed.

Roof covered with modern metal tiles - practical solution for a private cottage, country house or townhouses. Contrary to the beliefs of homeowners, the durability of such a roof does not entirely depend on the quality of the roofing material. Big influence The durability, waterproofness, and reliability are influenced by the additional elements used for installation, despite the fact that their area is less than 5% of the roof surface. In this article we will tell you what a wind strip for metal tiles is, what it is needed for, and how it is secured.

The wind strip is one of the additional elements used for metal roofing. It is a corner made of plastic or galvanized metal and performs protective and decorative functions. Distinguish the following types wind slats:

Important! The wind strip is a corner with 2 fastening shelves; the wider they are, the more reliably this additional element for the roof protects the overhang from the penetration of moisture and wind. Installation end element often performed in conjunction with a seal that follows the waveform of the coating for more efficient operation.

Materials, sizes

For the manufacture of cornice wind strips, materials are used that are highly resistant to atmospheric conditions, as well as mechanical strength. The service life of a metal tile roof is at least 20-25 years, which means that additional elements should last no less. The most commonly used strips are:

Steel. The most popular models of additional elements for protecting the ends and cornices are steel ones. Galvanized steel, which is coated with a layer of paint, pural or polyester during the production process, can withstand exposure to water, does not corrode, and is quite light and durable.
Plastic. Polyvinyl chloride is a thermoplastic plastic used to make cornice and end strips. The advantages of this material are: a light weight and diversity color solutions. However, plastic elements are subject to thermal expansion, and installation on them is not recommended. thermal cable for heating the roof.

Please note that the sizes of eaves strip models for metal tiles vary greatly. This additional element usually has a length of 1.5-2.5 m, the width of the fastening shelves is 15-30 cm. Steel products are made to order according to the buyer’s dimensions.

Functions

Additional elements in a metal tile roof, depending on the complexity of the structure, account for 2-5% of the area, but their importance can hardly be overestimated. Installation roofing without wind strips leads to the penetration of moisture and wind into the rafter frame and, as a result, accelerated wear of the material. The cornice and wind strip perform the following functions:

Protective. The main task of the eaves strip is to prevent atmospheric moisture and cold wind from penetrating under the roofing material. Because of high humidity wooden frame dampness and rot, which negatively affects the service life of the roof. Blowing in attic room cold air increases home heating costs.
Decorative. Installation of wind strips allows you to carefully and aesthetically cover the front board, as well as hide the “insides” from view. rafter system. Additional elements are selected to match the color of the metal tiles, so the slopes look holistic and harmonious.

Experienced craftsmen claim that additional elements for metal tiles can be made with your own hands. Wind bars are made from sheet metal thickness 0.4-0.5 mm. However, homemade planks will not look so neat.

Installation

Wind bars are simple elements in design, so the models different manufacturers They differ only in the type of coating and the thickness of the metal used. The effectiveness of these devices depends on correct use. Installation of cornice and end strips is carried out as follows:

The cornice strips are fixed to cornice board to laying the roofing material. Before installing this additional element, brackets for the gutter are fixed to the eaves. After this, the wind strip is overlapped by 10-15 cm and secured to the cornice board using nails or self-tapping screws in increments of 30-50 cm.
Wind strips are fixed to the front board after laying the metal tile roof. They should overlap the roofing material by 1 wave. The overlap between these elements can be more than 50 cm. Each plank is fixed to the board with 4 nails or screws to avoid deformation in strong winds.

Important! The joints between the wind slats must be sealed and not allow water to pass through. To do this, they are treated with silicone-based sealant.

If you think that the roofing material is sheets of metal tiles and that’s it, then you are deeply mistaken!
In addition to the roofing material itself, quite a lot of a large number of so-called additional elements.
All kinds of valleys, strips, skates, which are designed for joining together various parts roofs.

There are not so few such elements on the roof.
This can even be understood from their cost: the cost of a set of additional elements is 15% of the cost of the entire roofing cake.
And the more complex the roof structure on your building, the more additional elements you will have to use.
For some reason, most developers believe that roofing material sellers, by reminding them of the need to purchase these elements, seek to earn extra money.
This is actually not true.
The function of these elements is not only decorative.
They still reliably protect the rafter system and roofing pie from water getting in there.
Typical representatives additional elements are cornice and end strips.
Cornice strip (dropper) is one of the essential elements.
In addition to the decorative function, this element also performs a protective function.
It is designed to reliably protect the frontal board of the cornice from precipitation, prevent this board from getting wet and moisture from penetrating under the roof when a strong side wind blows.

The water that drains from the roof, thanks to the drip, enters the drainage system.

Protective strips are made from the same metal and using the same technology as standard sheets metal tiles.
The thickness of the steel sheet is 0.4-0.5 mm.
And in the same way, the cornice and end strips are covered with a layer of zinc and polymer protective coating.

In those houses where the roof structure does not provide for the installation of a cornice strip, or the tightness of its fastening is broken, smudges begin to appear on the walls, and metal elements rust will form.
End strip in appearance it very much resembles a cornice strip, but only such a product is not attached to the cornice part roof slopes, and at their lateral ends.
This element performs the function of protecting the sheathing from getting wet and protects against wind loads. roofing decking.
That is, during strong gusts of wind it prevents the roof from being torn off.
It is for this reason that it is often called a wind bar.

Installation

Before you begin to install the cornice strip, install the front board. To do this, it is nailed with galvanized nails front board to the end parts of the rafter legs. Sometimes, instead of a frontal board, a cornice board is nailed, securing it in special grooves pre-made in the rafters.
The next step is filing the cornice. To do this, use a tongue and groove board, siding or corrugated board. A support beam is attached to the wall of the house. This beam plays the role of a second support so that the roof eaves can be hemmed.
Before installing the cornice strip, the brackets are attached, into which the gutters will then be laid drainage system. The brackets can be attached both to the eaves strip itself and to the ends of the rafter legs.
The cornice strip is installed in place. If the brackets of the drainage system are fixed to the ends of the rafters, then it is installed on top of the brackets and attached to the front board. Self-tapping screws are used for fastening. The distance between the screws should be 35 cm.
The plank is mounted before the beginning of laying sheets of metal tiles.

Important!
When extending the cornice strip, you should not overlap more than 100 mm.

Installation of the end strip

Unlike a cornice, the end strip is mounted after how the roofing carpet will be completely laid on the roof.
Install the end strip so that it covers the ends of the roof.
For installation, you must perform the following steps:

The end strip is installed according to the height of the wave of the laid metal tile. It should completely cover the sheathing. In this case, the surface of the end strip should be connected from above to the crest of the wave of the metal tile;
when extending the end strips, an overlap of 100 mm is made;
All joints between the roof and the wind strip must be sealed.

The end strip should be installed so that the crest of the wave overlaps.
If this is not done, then with a high degree of probability water will get under the metal tiles.
To block the crest of the wave, the metal tile sheet is flanged upward.

Where do you buy additional elements?

If you want the roof of your house to look beautiful and elegant, then all roofing materials should be of the same style and color.
It is for this reason that it is recommended to buy metal tiles not end-to-end, but several sheets more.
If suddenly for some reason the sheet has to be replaced, then the exact same tile, but from a different batch, may have a completely different shade.
And it will be very noticeable!
The same applies to additional elements.

If you purchase them elsewhere, the shade of their color may differ from the shade of the metal tile sheets.
Therefore, cornice and wind plates are purchased immediately in the same place where the sheets of material are purchased.
And it makes sense to purchase self-tapping screws here.
Then the color of their hats will not be different.
And with delivery, everything will be easier when all the material is purchased in one place.
By the way, you should know that most metal tile manufacturing companies provide a guarantee for their material only if you install additional elements good quality.
To avoid warranty problems, purchase everything at once in one place.
The price of one linear meter of eaves strips for metal tiles, depending on the coating, is 100 - 200 rubles.
Believe me: you will save on wholesale (when you buy everything for a roof, you will automatically turn into a wholesaler), you will save on delivery and nervous system you'll save it for yourself!

Metal tiles are one of the most popular roofing materials. One of the most important elements of a roof made from this material are strips for metal tiles.

They ensure reliable and long-term operation of the entire roof of the house. This article will talk about why metal roofing slats are needed, as well as how to install them.

For the manufacture of windshield and eaves strips, materials similar to the main roofing material are used. They are based on galvanized steel with a polymer protective coating. The thickness of the steel is 0.4-0.5 millimeters.

Metal tile strips perform the following functions:

Cornice strip for metal tiles it has an oblong shape. Its manufacturing technology is similar to the main roofing material. Its main purpose is to protect the frontal roof board from moisture during heavy rain. Consequently, the eaves strip also protects the roof space from moisture. The technology for producing the end strip is also identical to the technology for producing metal tile sheets. This element is fixed to the ends of the roof slopes.
End strip provides protection for the sheathing from the effects of water, and also evens out the wind load. Therefore, this element is also called a wind bar.
Junction strip. It is a universal element that performs protective and decorative functions.

The ridge strip protects the under-roof space from precipitation in the area where the roof slopes converge. It can take many forms.

Fastening the cornice strip

Attaching the eaves strip to the roof junctions is carried out as follows:

photo of cornice strip installation

The first step is to install the front plate. It is fixed to the ends of the roof frame using galvanized nails. Instead, sometimes a cornice board is installed. This element is fixed into special grooves on the rafter system.

The next step is hemming. For these purposes, corrugated sheeting or tongue and groove boards are used. When filing eaves overhang a support beam attached to the wall of the building is used as a second support.

Before installing the eaves strip, install the brackets necessary to fix the drain. They are fixed to the rafter legs or to the eaves board.

Next, install the cornice strip. Its installation is carried out before laying the metal roofing. The plank is attached over the gutter fastening using self-tapping screws, which are screwed into the frontal or cornice board. The distance between the screws should be from 30 to 35 centimeters.

The extension of the cornice strip must be overlapped. The overlap size should be 100 millimeters.

Installation of the end strip

After laying the metal tile roof, an end strip is installed. Its installation is carried out as follows:

installing an end strip

Installation of the wind strip is carried out at the wave level of the nearest roofing sheet. In this case, the corner of the roof end must be completely covered.
The end strip is fixed at the top and sides. Self-tapping screws are used for these purposes. Installation of the plank from above is carried out in the crest of the metal tile wave.
The extension of the wind strip is carried out with an overlap of up to 100 millimeters.
The joints between the roofing material and the strip must be sealed.
The end plate not only performs protective functions, but also decorative. This element must necessarily overlap the wave crest of the roofing sheets. Otherwise, water may get under the metal tiles. To do this, the edge of the sheet of roofing material is flanged upward.

How to install a ridge strip

When installing ridge strip First of all, you need to check that all necessary work on the arrangement of under-roof ventilation. To prevent snow from getting under the ridge, special strips are installed on the flat slopes of the roof.

photo of ridge strip

Installation of the ridge strip should begin from the end. The roofing ridge is laid on top of the end strips, and an outlet is also made to the outside by approximately 20 -30 millimeters. Elements of a flat roof ridge must be overlapped. The amount of overlap should be 100 millimeters. If the ridge elements have a semicircular shape, then they should be connected along the stamping line.

If the roof slope angle exceeds 45 degrees, then the location where the ridge board is attached, as well as the methods for fixing the roof ridge, may have significant differences depending on the slope of the roof slopes. At the stage of installation of the sheathing, it is necessary to simulate the installation of the roof ridge. In this case, the angle of inclination of the roof, as well as the shape of the ridge element, should be taken into account.

This installation method has become popular due to its accessibility and simplicity. If the angle of inclination of the roof and the ridge strip do not match, they are corrected with a metalworking tool. Upon completion of the installation of the ridge strip, which has a semicircular shape, it is plugged on both sides using special accessories.

Installation of the junction strip

Installation of the junction strip should be carried out after laying the roofing and installing the wind strip. Using this element, the valley carpet is fixed on vertical planes.

The junction strip is also used in places where the roofing covering abuts ventilation ducts and the chimney. In these cases, it acts as a sealed element. The abutment strip is installed upon completion of the construction of the roof of the house.

This element also performs decorative functions. It gives the roof an attractive appearance.

Where should you purchase additional elements?

In order for the roof of a house to have an attractive appearance, it is necessary to install roofing materials of the same color and style. Therefore, experts advise purchasing several more sheets of metal tiles than required.

The point is that it's exactly the same roofing sheet, but from a different batch may have a different shade. And this will affect appearance roofs. The same can be said about additional roofing elements.

If you purchase them elsewhere, their shade may not match the shade of the metal tile sheets. For this reason, windshield and eaves strips for metal tiles should be purchased in the same place as the main roofing material.

It should be noted that most of companies that produce metal tiles provide a guarantee for their products only if high-quality additional elements are installed on the roof.

To avoid warranty problems, it is better to buy everything roofing elements In one place. The price of 1 linear meter of cornice strips ranges from 100 to 200 rubles, depending on the coating.

Video on how to install the plank:

Any, even the most simple roof, involves the use of special elements that form its joints, kinks, junction points of slopes and areas adjacent to walls and gables.

She protects against getting wet the frontal board of the cornice during precipitation;
Prevents moisture from entering under the roof and in the interior;
Gives completeness attractive appearance the entire structure;

Sectional diagram

Design and principle of operation

Cornice strips form a metal protective edge with anti-corrosion coating, protecting the frontal or cornice boards from moisture getting on it.

Looking at the roof first, it may seem that this longitudinal element is brought under the edges of the roofing. In fact, its installation is carried out even before laying or. Only after it has been strengthened on the frontal or cornice board will it be possible to begin laying facing materials.

Usually, made from the same material as the cladding, it is painted in a color similar to it and protects not only the eaves or front board from getting wet, but also prevents water from entering the under-roof space itself.

Cornice device

Drip rail and cornice strip - what are the differences?

Many people mistakenly believe that the cornice strip and drip represent one and the same thing.

In reality, they are two different bars that perform two different functions.

The eaves strip protects the frontal board of the eaves from getting wet, and the drip is used to remove water, namely condensation from the waterproofing, from the most important elements of the roof structure into the gutter or directly to the ground. It is especially important in autumn and spring when high humidity air and frequent rains;
protects the facade of the house from the formation of fungus, mold and leaching construction mixture from brickwork, as well as from wood rotting, while the eaves strip protects the roof itself;
The drip cap strengthens the roof and protects it from air masses, and the cornice strip protects it from aggressive external influences;

Both additional elements can be installed together or separately, but they cannot replace each other.

Cornice strip: dimensions

The strips protecting the roof are made of galvanized steel profiles. Manufacturers use the same thin sheets of steel for their production, the thickness of which varies from 0.4 to 0.5 mm, as for production metal tiles.

They are covered with the same polymer materials, for example, polyester or plastisol, which, in turn, coats metal tiles. When using composite metal tiles, the planks are covered with basalt chips. The approximate length of the element is vaped within 50-60 cm.

Because the plank is, as it were, “planted” on the base of the roof, the required footage is collected from its individual parts.

Installation of cornice strips

Installation of additional elements attached to the cornice, carried out on an already prepared frontal board, which is nailed with galvanized steel nails to the end parts of the rafter system. If the front board is level, attaching the plank will be much easier.

Installation of cornice strips is carried out in the following order:

The frontal area of the roof base is hemmed with tongue and groove boards. You can use siding or corrugated sheets for these purposes;
Then on the wall of the house support beam is installed, serving as a safety support when hemming the eaves overhang;
Right before the event finishing works cornice the drainage system is equipped with brackets or hooks, attaching them to the rafters or to the eaves board. In them, further, the gutters of the drainage system will be folded. If the distance between the rafters is the same, it is better to attach hooks to them;
Lower the first hook or bracket below the continuation of the slope line by 2 cm in order to ensure that water from the roof is guaranteed to enter the gutter.
Next comes the turn of fixing the cornice strip over the gutter fastenings to the front board. It is nailed down with screw spacing of at least 30-35 cm in a checkerboard pattern.
The planks cannot be attached end-to-end or with gaps between them. Each subsequent plank must overlap, namely, go about 1 cm onto the already fixed element. The last bar is adjusted to size by a neat cut.
Having completed the installation, you can begin cladding the roof or. And after finishing laying the roofing materials, you should start installing other additional roof elements.

Additional elements

We invite you to familiarize yourself with other types of additional roofing elements:

used as a decorative component to mask the joints of roof cladding with corrugated sheeting. They protect the ventilation gap of the under-roof space and joints from seepage and water retention;
End strip protects sheets of metal tiles or corrugated sheets, covering them at the ends, from strong wind, water penetration under the roof in the area where the roof adjoins the gables, and also prevents insects or birds from entering under the roof;
Wall strip used in areas adjacent to walls or other vertical planes.
Wall straight protects the joint without grooves with additional sealing;
Wall bottom is attached under facing material, metal tiles or corrugated sheets in the area of attachment to a wall or other surface located vertically. At one edge of the additional element there is a fold that prevents the drainage water from overflowing over the edge.
directs water flowing from the roof, mainly performing decorative role masking the internal areas of the joint of sheets of roofing material.
Lower endova- an element used in areas where negative angles meet. It protects the junction of sheets of metal tiles or corrugated sheets from water seeping under the roof;
Low tides- an element designed to protect the joints of the window and the walls of the building from water penetration;
used on various roof fractures. They protect the joint from the penetration of water under the roof space;
protect against unexpected avalanche-like snow masses, as well as unintentional falls components roofs;
Internal and external corners — decorative elements, used to mask the joints of internal and external corners facing material roofs;
Ridge aerator- a product used to get rid of excess moisture in the area under the roof;
Ridge cap- an important component that prevents dirt and moisture from getting under the roof.

Additional elements

The work of all additional roofing elements together is aimed at maintaining the integrity of the roof and increasing its service life. The absence of any element can, although imperceptibly, have an extremely negative impact on the design of the house as a whole.
