Roof overlap using different materials

On how correctly the roof covering will be equipped, the convenience of living in the house and the durability of the building's constructions directly depends. The materials intended for sheathing the roof frame, there are many. Installation of each of them is done in compliance with certain technologies. Most often, the roofs of houses are trimmed with slate, metal roofing or corrugated board.

How can I cover the roof

There are two main ways of covering the roof frame: with or without insulation. The second option is usually used in small country houses with lofts of small area. The roof of cottages is most often insulated. This allows you to equip a comfortable attic, thus increasing the living area of the building.

When assembling an insulated roofing system , the following materials are usually used:

• Vapor barrier;
• Material for the inner skin;
• A heater (most often mineral wool);
• Waterproofing (technical polyethylene film);
• Actually the roofing sheets themselves.

All these materials must be installed in a strictly defined order. Collecting roof overlap in a cold way, apply only a waterproofing and roofing sheets.

What you need to know about

Whichever method of roof carcass plating is selected, a ventilation gap must necessarily be arranged between the waterproofing and the roofing material. You can do it by installing a control bar from the bar.

The sheets on the roof frame should be fixed using the fasteners intended for this type of roofing material . Before the beginning of the plating, all the wooden elements of the truss system should be treated with antiseptic and fire-resistant compounds.

Cold roof installation: features

If the loft in the house is supposed to be unheated, the roof covering is arranged in several steps:

• On the rafters fix a waterproofing film;
• Mount the crate;
• Cover the roof with the selected roofing material.

The film is supposed to be fastened with a sag about 2 cm (except for some modern expensive waterproofing). The overlap between the strips should be made at least 15 cm. To ensure their tightness, it is worth to additionally glue with adhesive tape. To fix the film is recommended brusks with a thickness of at least 2.5-3 cm. Thus, the necessary ventilation gap is arranged.

The cladding is mounted in steps specified for a particular roofing material. The boards under it should be taken strong enough. The timber should be not too wide and not particularly narrow. Thick bar or very wide boards in the process of exploitation of the roof will necessarily disintegrate. Too narrow or thin lumber can not withstand the weight of sheets and snow in winter.

Building a warming pie

In residential houses, a roof covering is more thoroughly built than in country houses. Insulation of the roof, as already mentioned, is worth doing in the event that there is a desire to equip the house with a comfortable attic. The procedure in this case will be the same as when assembling a cold roof. The only thing, when installing a warm roof between the rafters before fixing the waterproofing plate are installed mineral wool plates.

To ensure that the insulation does not fall out into the attic, it is supported by boards or simply stretched wire between the rafters. To install mineral wool should be voraspor. The steam insulator and the internal cladding are mounted after the roof has been covered with sheets. In this case, the film is also fastened to the rafters by means of bars to provide an air gap.

Begin the installation of roofing material immediately after the assembly of the "pie". Otherwise, the waterproofing film may be damaged by wind or as a result of accidental mechanical influences.

Features of slate mounting

This material, despite the fact that it does not differ with a particularly attractive appearance, is quite in demand on the market. Many of the owners of country houses are equipped with slate roofing. It's all about its very low cost. Slate roofing is usually 1.5-2 times cheaper, for example, the same metal-tile roof .

In order for the roof covered with this material to look more attractive, the sheets can be pre-primed and painted using a special paintwork.

Work with slate when covering the roof should be as carefully as possible. After all, the material is quite heavy and at the same time fragile. On high houses in 2-3 floors before the roofing of the roof it is worthwhile to build forests. Use slate is allowed only to cover the ramps with an angle of inclination of at least 22 degrees. Too often a crate for this material is usually not done. Under each sheet, in most cases, three planks are laid - along the edges and in the middle.

This material is mounted to cover the roof from right to left and from bottom to top. On roofs with a slope angle of skates of less than 30 degrees, a vertical lap is made at a minimum of 12-14 cm, and horizontal - by two waves. On the roofs steeper than 30 degrees the first indicator can be 10-12 cm. The horizontal overlap in this case is usually made for one wave.

The order of laying asbestos cement sheets

Actually, the installation of the slate itself is done in the following order:

• Mount three sheets of the lower row;
• Set two - the next row;
• Three lower sheets are mounted again.

According to this algorithm, the roof is closed to the very ridge. Mount slate sheets should be on special nails. In this material holes are pre-drilled. On each sheet usually leaves 4 nails. Under them, you should always use a rubber gasket. Attach slate sheets to prevent the destruction of the coating due to temperature fluctuations with a slight backlash. Scoring nails should be at the top of the wave.

After all the slate has been laid, to ensure the integrity of the roof, you need to install a ridge element. It can be made from tinplate or painted boards.

Evroshifer (ondulin and other varieties) is mounted about the same technology. The only thing, in this case, you should carefully read the manufacturer's instructions. It can describe some of the installation-related nuances.

Roof overlap with metal tile: basic rules

This material costs more than slate, but it also lasts much longer. In addition, the metal tile looks much more attractive. Mount these sheets can be on the roof with a slope angle of skates from 14 degrees. The step of the battens in this case depends on the width of the material wave. Fill the boards so that they fall under the crest of a wave.

Installing sheets

Actually, the very order of stacking sheets of this variety is about the same as that of slate. This material is usually supplied with a large number of different kinds of additional elements. Before proceeding actually to the roofing of the roof with metal roofing sheets, a spillway system should be installed.

To do this, including independently, is not difficult. Preliminary, at the lower edge of the ramp, a curtain rod is installed. Fasten it using self-tapping screws, positioning them with a step of 25 cm. Actually, the trough-receiver itself is fixed by means of arc-shaped brackets installed at a distance of 1-1.2 m from each other. Gutter pipe is fixed to the wall on special clamps.

At the next stage, mount the bottom end carpets (if required by the roof structure). Overlapping of the roof, assembled using metal roofing, are also obtained with reliable installation of the waterproofing flume of the chimney. Only after installing the latter you can proceed to fixing, in fact, the sheets of roofing material. Cutting metal tiles exclusively using simple scissors for steel or electric. Bulgaria can not be used for cutting this material. When installing the sheets themselves, care must be taken to match the capillary grooves.

After the roof has been sheathed with sheets, the gable end boards, the ridge element, the chimney apron and the upper valley are mounted.

How to install corrugated board

The principle of mounting sheets of this variety is similar to the technology of roofing metal roofing. Overlapping of the roof with corrugated board, however, can be done even if its slopes are inclined less than 12-14 degrees. Weigh this material a little more metal. It is cheaper, but it is more difficult to lift it to the roof. However, in fact, the installation of the corrugated board is simpler than metal roofing. The point is that in this case it is not necessary to monitor the capillary grooves and the safety of the upper protective layer. Cutting corrugated board can be including a Bulgarian.

How to make roof overlap using other materials

In addition to metal and asbestos cement sheets, roofing materials can be used to protect the roof, as well as flexible or clay tiles. Rolled soft materials are usually used on gently sloping roofs (up to 15 degrees). The casing under the roofing material is arranged solid - from plywood or chipboard. Glue bands in 2-3 layers on the melted bitumen. They also miss seams.

When using flexible shingles on a continuous crate, a backing carpet is pre-assembled. The roofing material itself is simply glued on it in a certain order with a sticky layer down.

Under the clay tiles, because the material is heavy, they equip a strong crate from the bar with a step corresponding to the size of the tile. This material is fixed to the roof frame by means of screws through special holes (with backlash). Each third shingle is clamped.
