Features of the selection and installation of aluminum roofing for a private house

Aluminum roofing is often underestimated by many consumers and developers. There is a strong opinion that the roofs on a private house made of other materials are always more practical. However, in reality this is not quite the case.

The roof of aluminum is used not so long ago as products from copper and steel alloys. But a number of advantages allowed them to become one of the leading options on the market. Aluminum structures are strong and relatively light, with their help you can create a new coating or repair an existing one. Excellent corrosion resistance, long use time and aesthetic advantages also favor the winged metal. But it is important to carefully select products from it and evaluate their advantages and disadvantages.

Like all metals, aluminum expands rapidly when heated. If you put the coating on the frame hard, it can bend and even become covered with cracks. Another characteristic difficulty is significant heat loss and severe overheating. Partially this disadvantage is eliminated due to thermal protection, but because of it, the time of work and the cost of construction (repair) increase. When striking the roof surface of raindrops, hailstones, when moving the birds below there is a strong noise; more aluminum is more expensive than simple galvanized steel, but the cost overruns on its acquisition are justified by long service.

The roof based on aluminum is represented by such main types as:

• fold covering;
• professional flooring (he is professional sheet);
• metal tile;
• shingle.

Fold type is formed by metal paintings, connected by a single or paired mount. Placing a strong castle outside the plane of the roof makes the house as protected as possible from rainfall. The metal tile turns out due to stamping of the sheet of aluminum; This technological technique gives the coating a fair amount of flexibility and an easy-to-use structure. Technologists and consumers appreciate such designs for the opportunity to get a relief of a complex profile.Profiled - wavy material, the relief of which is formed by trapezoids or rectangles.

By production of a professional flooring, it must be supplemented with stiffeners, otherwise the resistance to normal operating load will be very low. Longitudinal structures feature improved drainage of water and snow. As for the shingle, such a word is used to refer to special blanks that allow forming a coating for a unit roof. Most often shingle roofs make double-layer or three-layer, which allows to make waterproofing more qualitatively. The appearance of such a roof is similar to fish scales, but the elegant look turns into a serious problem: only experienced craftsmen will be able to do all the work properly.

Roofing aluminum is easier to install than slate, because it is not so fragile. But there are special nuances. So, seam seams can be formed by both manual and electric tools. Before laying the material it is necessary to prepare a layer of anti-condensate film. It will ensure the dryness of the metal from the inside and transfer all condensable drops of liquid into the drainage system.

It is desirable to lift up the aluminum folds one by one., and roll up (connect them and give the desired shape) - directly on the roof. The best results are achieved if the length of metal sheets coincides with the length of the slopes: then there will be no need for horizontal folds, and the final coating will become more reliable and sustainable. It is undesirable to use sheets longer than 10 m, since they are too easily deformed with temperature changes.

The installation of a folded aluminum roof involves attaching one of the edges to the clamps with a step of 60 cm. If you have to use sheets of more than 10 m, they must be held by floating clamps that can suppress thermal expansion. Aluminum slate is put on a similar pattern (folding is applied in the same way, and self-tapping screws do not need to be screwed). The bases are solid and sparse, but the slats can not be separated from each other by more than 250 mm. Klyammery put at a distance of 300-400 mm from each other, attach them to the crate on the screws.

Important: screws and nails must be inserted into the base slats at right angles. All recommendations of the manufacturer should be followed when working extremely strictly and clearly.

Wave aluminum (slate) can be used even where it is absolutely impossible to exceed the design load. Special coatings allow you to give the roof surface a very different appearance: the texture of copper, ceramic tile, and even natural wood can be imitated.

To choose the most suitable option for the price, you need to pay attention to:

• panel thickness;
• profile height;
• execution of galvanization or type of applied polymers.

Important: with all the advantages of aluminum slate corrugated sheet is much more practicaltherefore, it has almost displaced the previous version from the market. This option is much easier, it lasts longer, and it is relatively easy to mount it. You should not only buy material without an external zinc or polymer layer: such a product is intended exclusively for interior use.In terms of reliability and elegance, polymer casings are considered the best, but this turns into their increased cost.

As for marking, corrugated sheets of categories H and NS are intended for the roof; wall profile can be used minimum category C20 and above. Laying material permissible on the roof, the slope of which is at least 11 degrees. The exception is self-supporting profiles with a significant height of the corrugations: they can be applied even on flat bases. Calculating the need for the material, you need to remember that stacking is performed with an overlap in one corrugation. It is required to attach the blocks to the substrate on self-tapping screws with sealing gaskets.
