Slate roof with his hands

Advantages of slate

Reasons for its popularity are many, they can be attributed, and a long service life and high functional properties. But the main thing that attracts the attention of consumers slate - a unique value for a relatively low price and high quality. Reliability wave Slate is able to protect a home from the vagaries of the weather and give the house a cosiness. A roof slate will last considerably longer than the roof of any other material. This is only a small part of the advantages of slate.

Technology of production slate

For many years, it is used in the construction of a roofing material such as slate. Today, he is still one of the most popular ways to overlap roof, and probably the most common.

Initially, the roofing used natural slate. Natural slate tiles called, obtained as a result of natural separation of rocks, rather shale, from which came the name of the building material. Nowadays you can still find some places of the roof of natural slate, built in the Middle Ages.

Sheet slate design is of two types: flat and wave.

To flat slate was more rigid in its structure adds a special chrysotile fibers that act as a reinforcing element. Basically, this material was used Walling furthermore includes a flat slate construction wall panels, which can significantly improve their thermal insulation properties.

The main direction of the wave Slate is the formation of the roof. Latest slate processing technology has allowed to make it more durable and give an attractive appearance. wave Slate sheets have ...

cons slate

• Such material as the slate is very difficult to transport, it is sufficiently fragile. Because hundred slate sheet thickness disproportionate to the volume necessary to move it in the vertical position, otherwise it may crack.
• It should exercise extreme caution, if necessary, by a slate roof.
• Over the years, the color of slate may change under the influence of the environment.
• Transverse edges Slate often break off
• Waterproof properties of slate over the years, become worse.
• If the Slate is in the shade, then it can form lichens.

Advantages and types of asbestos-cement slate

In today's market of building materials there are several materials that are available in the form of wave sheets, they are called slate. All these materials are divided into three types: the euro, metal and asbestos slate.

Metal roofing slate is made from galvanized sheet steel, which is later covered with a protective film of polymer. In the production evroshifer applied several components, such as fiberglass, cellulose, a basalt fiber and jute.

Neither metaloshifer nor evroshifer not contain asbestos in its composition, they are on the bitumen. The popularity of these kinds of slate and could not catch up with the popularity of asbestos-cement slate.

Its composition can be judged by its name. The strength of the asbestos fibers in its composition superior in strength steel wire and cement, acting as a connector, makes the material hard as stone. When fine fibers are uniformly distributed on asbestos cement, they form a reinforcing mesh which greatly increases the reliability of the material and its toughness.

Types of Corrugated asbestos slate:

• IN - is corrugated sheets slate rectangular shape with the conventional profile. Besides the standard sheets are produced the various parts of the roof.
• SW - a unified slate wavy. Dimensions of this Slate help to reduce the number of joints that is what brought him widespread popularity.
• VU - slate corrugated sheets with the reinforced profile. It is intended to cover the production facilities.

The roof of slate and its installation

Preparatory stage

Before we proceed directly to the installation, you must carry out a number of preliminary operations. First of all, it is necessary to measure the surface area to be coated. After the measurement will be finished, it will be possible to calculate the amount of materials needed for the roof slab. Based on the amount of material possible to make an indicative budget for the purchase of materials and execution of works.

In order to calculate the area of ​​coverage and the necessary amount of material you can use the design of the building, if it is not then it is not a problem. Area can be calculated based on the measurements made.

Before starting the installation of the roof is necessary:

• To conduct inspection of slate to detect cracks or chipping;
• Measure the sheets;
• Mark and drill the holes for the fasteners;
• Carry out the necessary cutting work Slate. When cutting out an asbestos slate recommended to use steel chisels, or power tools.

painting slate

The service life can be extended, to paint it with a special paint. This not only prolongs the service life, but will give it a beautiful appearance, the appropriate design solution exterior of the house. Special acrylic create a special protective layer on the surface of slate, which would slow down the process of destroying a mixture of slate.

If you apply a water-emulsion paint, then, uniformly covering the surface, it would delay the microcracks film. With this coating the water will drain quickly from the roof, and the snow and ice, it will create a rolling effect.

A good solution would be the use of alkyd paints. After drying, they create the effect of elasticity, which prevents the formation of cracks. Special elements in the composition of alkyd paints to help prevent burnout, protecting the roof from direct sunlight. When applying such a coating it is likely that the slate can last for yes two times longer.

Mounting battens for slate

By itself, the process of creating the crates under the slate operation is not difficult, the main thing to know all the necessary details. Asbestos-cement sheets of slate are heavy, for this reason, the installation lathing requires a special responsibility.

installation steps

Mounting battens for slate produced in several stages.

Step 1. The first step is to install the beams and rafters fix. Depending on the length of the ridge of the roof rafters la crates should be set in increments of 1-2 m. each truss pair is formed from two bars which are fixed at an angle via a crossbar.

Step 2. The second step is the installation directly crates. Start packing crates better below. For this timber is placed on the lower edge of the rafters, and then fixed by several nails. Sufficiently high strength slate sheet allows you to move crates quite rare. The main thing that the slate was attached to the joists on the edges and in the middle. If slate sheets have standard dimensions 120 × 68 cm, then is fine pitch batten 50 cm. To crate is securely fastened to the rafters, as the fixtures you want to use galvanized nails, their length should be between 70 to 80 mm. At this stage it is important not to forget the presence of the drainage gutter, from there it is or not will depend upon how far from the wall should be the edge of the eaves.

Step 3. The third stage - is to ensure heat and waterproofing. Most frequently as a material for a crate stacked on the waterproofing roofing material. So when laying roofing felt it was not difficult to move around the joists crates, stack it better vertical rows. For this roll is thrown through the roof ridge and carefully unfolds. Attach roofing felt need by using staple gun, and special clamps, wherein the rows of waterproofing material must lie overlapping and enter one below the other approximately 10 cm. Sometimes, instead of roofing waterproofing membrane is used and a layer of fiberglass. At the same time to keep the glass, the roof is necessary to incite the special building cardboard.

Step 4. In the fourth stage address issues of abutting to the chimney. How roofing slate will be adjacent to the chimney, it is directly dependent on its location. If rasplozhen pipe on the ridge of the roof, the bottom apron is mounted on top of waterproofing. It must be made of sheet metal and must have a notch under the smoke tube. Slate sheets are stacked on top of the apron around the tube must be laid asbestos. In those cases when the tube is located on the slope of the roof, there are two options contiguity slate sheet. If waterproofing is provided, the backsheet contiguity installed under slate and film. If waterproofing is not present, the sheet abutment is mounted so that it was above the pipe beneath the sheets, and below - on top of the sheets.

Quite often, in order to seal the space between the slate and grout tube is used instead of the upper apron.

Nuances batten installation

In choosing the material for the crates there are some nuances, which we should not forget. If the timber is too thick, the prolonged exposure to moisture it may be deformed if the timber is too thin, it is impossible to ensure the strength of the whole structure. 50-75 mm - the thickness of such a timber can be considered optimal.

To create crates are best-edged boards without bark. This is necessary to ensure that no further proved that live under the bark beetles or larvae of insects that will destroy the crate. To avoid this, it is necessary to impregnate the board Bioprotective means, and fire-retardant impregnation did not hurt.

Sometimes it does not work immediately after the laying of roofing material to begin the installation of slate, in which case the roofing material must be secured. To do this, it stapled to the wood battens are targeting, this will help avoid shearing roofing wind.

Technology laying slate roof

Installation of slate sheets taken hold vertical rows below the top, with a high wave should fall on the low tide of the previous row overlap. The topsheet should overlap the bottom of about 10-20 mm. To the edge of the roof it was even necessary to stretch the tape, which will serve as a reference point, as it will add the convenience of installation.

There are two ways of stacking corrugated slate, are popular. The first method - the offset of the second - with corners cut sheets. Selection depends on the method of laying the roof T configuration.

Stacking with offset

For roofs with a narrow vertical ramp and wide horizontal ramp optimal option is offset stacking.

With this method of stacking cut sheets in unnecessary places splicing. Attach first sheet slate begin at a distance from one wave lathing. Further attached a second sheet of the same row, it is laid overlapping the first, in one wave. The first sheet of the second series is placed on one or two overlapping the first. Installation of all the other sheets is similar.

Stacking cut corners

Such a method is applied for laying ramp narrow horizontally wide and vertically.

In this method, two sheets of slate sawing off diagonal corners, then sections of the joint, leaving a gap of up to 3 mm. It is necessary that the slate is not bent at the junction of four sheets and lay flat. Otherwise cracks may appear thereon.

That which corners should be cut depends on the party slate stacking sheets. If the roof is mounted on the left to the right, then in the first row is processed by the upper left corner, and the last - right bottom corner. On the middle leaves are processed two opposite corners.

Important!

For fixing slate sheets best suited galvanized screws having a cap and rubber gasket, their length must be at least 100 mm. Professionals advise for fixing slate acquire screws whose thread ends before reaching the cap, otherwise the thread will damage the sheet.

It is necessary to firmly tighten the screws, but need to be careful, otherwise the slate crack. The number of attachment points will depend on the dimensions of the sheet. If the sheet 6 par, it is possible to dispense with screws 4. 2 will be located on the second wave and 2 at the sixth.

If necessary, cut a sheet or a cut angle primarily need to humidify the cutting place. This simple technique will not only facilitate the process of cutting, but also significantly reduce the amount of dust. Slate sawing the sheets grinder, a charged plate of stone or a hand saw. The same method works well, wherein in the cut line drawn by drilled holes with a pitch of 1.5 - 2 cm. after the holes are ready to break off a piece of slate would need only a little effort.

The final stage of installation of roofing slate

The last step slate roofing assembly installation can be considered metallic ridge and cracks under subsequent filling with foam sheets slate.

It is necessary that overlaps the ridge slate sheet to 20-25 cm.

In order not to damage the integrity of the slate will have to show accuracy when working with assembly foam.

All zatenenennye should be carefully treated with paint, which used to be painted sheets.

The final step in installing the slate roof should be fixing the angular elements, their finishing, as well as the installation of the drain.

Rules for the care and repair of the slate roof

As a result of the weather, biological and mechanical effects on the slate can develop cracks and other damage types.

Since slate sheets rough surface, they often accumulate dust, leaves and other debris, the presence of which can give rise to various kinds of moss and lichen, which represent a serious danger to slate roof. The whole point of acid-produced substances that can corrode the slate. If as a result of mechanical action on the slate chips are formed, the later they can lead to crack formation. Dense snow formed during the big snowfall, can lead that the slate will crack under his weight. With the onset of thaw slate tends to slide with a layer of snow. And that's not all hazards can destroy slate roof to slate roof as long as possible has retained its properties, it needs proper care. Every six months, you must check the condition of the coating.

Slate sheets must be cleaned regularly. To do this, you can use a broom, but cleaning with the electric pump will be effective.

In winter, snow and icing it is desired to remove.

If the slate roof is in need of some renovation. The effort it will take quite a bit:

• The first step in the repair should be to create a mixture that will be stopped damage. It may look like: cement, asbestos diluted in proportion 2: 3, and the resulting mass is added PVA glue.
• After the mixture is prepared to do a preliminary purification treatment surface. First, it is cleaned of debris.
• Once the debris has been cleaned, dust and dirt are washed with water, after which the surface give a good dry.
• Next, onto the surface glue is applied diluted by water
• Then, chips and cracks are sealed previously prepared mixture. It is important that the layer thickness is not less than 2 mm.
• After a good slate surface is dry, it can be painted.

Regular and proper care of the slate roof slate roof will serve for many years, and some simple repairs conduct further extend its service life.
