Metal tile

In the spring, construction and repair work is flaring up with renewed strength. People build houses in their cottages and cottages. Only preliminary it is necessary nevertheless to estimate volume of the future works and to be reserved with necessary materials, including for a roof. Practice shows that for the roof the best choice will be metal roofing.

Today more than 70% of Russians prefer this material. Nevertheless, there are also questions to this roof covering. Some shortcomings are just myths that are related to metal tile.

Metal tile

Metal tile – expensive material.

Builders argue that there is simply no equal metal tile for the price-quality ratio. Analog in value can be considered ondulin. But the metal tile though more expensive, but has a number of advantages. First of all, it should be said that this material does not fade with time. But ondulin in 5 years will lose its former appearance. A counterfeit material will retain the original gloss even less. It should be noted that after years of use, the ondulin will look very shabby. A metal tile on some objects has been lying for more than 10 years. In this case, both its state and appearance do not change. After all, for this material 10 years – the minimum period of operation, but in fact it will last much longer. So the cost of “cheap” ondulin should be added and the cost of its replacement and repair for a long period of operation. So it turns out that metal tile in the end will be cheaper.

Many scraps are obtained from metal.

When ordering a roof, you must carefully select your supplier. After all, he can prepare a metal tile of accuracy in accordance with the project. In this case, the sheets will already be cut and cut in the most optimal way. Without waste, of course, not do, but the volume of them will be minimal. But a large number of scraps is formed when metal tiles are purchased directly in batches in the market. In this case, a competent calculation of the layout of the sheets is simply not carried out.

In the rain, the roofs with metal tiles are noisy.

Such roofs can really make noise, but only when they are incorrectly mounted. This can occur if you use an insufficient number of screws, or if you do not tighten them properly. It is worth blaming in such a noise and loose fit sheets of metal tile to each other, as well as the crate. In this case, raindrops will become a source of noise. In the general case, the roofs over residential buildings always have a thermal insulation, which perfectly resists external noise. Therefore, to consider this problem global is certainly not worth it.

With metal roofing, the polymer coating often peels off.

It should be understood that any building material can be of different quality. If the technology was not observed in the production of steel with a polymer coating, then it can really go away. If the material is produced qualitatively, then the coating will last for ten years. You can advise here only one thing – you should not pursue a penny profit, but it’s worth choosing a reliable manufacturer and supplier. Usually they even give the guarantee for the most economical class of their products for 10 years, and it lasts much longer. After all, the strictest control is carried out for all production, starting with steel rolling at a metallurgical plant, where technological norms are strictly observed.

Metal tile serves as an object attracting lightning.

This is why it must be grounded. Electricians believe that any roof, covered even with slate or ondulin, needs protection from lightning. To do this, a lightning grid is installed at the top, from which the current collectors are led along the facade, and the contour is installed in the ground. In addition to this, sometimes at the highest point of the roof, another rod lightning receiver is put. If the roof is metal, made of copper or galvanized, then it really is itself a lightning detector. In this respect, metal tile is not much different from slate or ondulin.After all, the sheets are covered with a polymer coating, and there is no guaranteed contact with each other.

Metal tile

Metal tile will not look good on the roofs of wooden houses.

Manufacturers of houses from a profiled beam claim that about half of customers prefer metal roofing. You can successfully choose its color, the combination of wood and metal can be very good. So, a wooden house will become more elegant with a burgundy, brown or dark green roof made of metal.

With slippery metal, snow will fall avalanche.

To avoid snow landslides, tubular snow holders can be used. They will cut the snow mass and make it fall safe for people and their things. Yes, and cars parked near the walls, will feel much calmer. Put snegozaderzhateli must be on the perimeter of the roof and under the mansard windows. Usually, these improvements are purchased as an additional option to the roofing system. By the way, they are needed not only for roofs with metal roofing. After all, with a set of mass snow will still come down, regardless of the coverage. Therefore, the less it becomes slippery, the later it will happen. Consequently, the mass of snow will be much greater.

про Between the sheets of metal under the roof of the water will seep.

Qualitative metal tiles have a clear geometry. Proper installation provides for the installation of overlapping sheets and their close fit to each other. Thus, water can not penetrate into the interior. And the flow process is facilitated. To do this, on the first wave, each sheet has a special groove-capillary. It is also important to say that any roof under the coating has a layer of waterproofing. And to exclude the possibility of leaks through the fixing holes, special screws with a painted head and a waterproofing EPDM gasket are used. All this makes it possible to avoid leaks in the case of properly installed roofing of metal roofing. But about other materials, this is hard to say. So, a bitumen-based roof very poorly tolerates low temperatures. From this they become fragile, which is fraught with damage and leaks. In the case of cement-sand tiles, a poor role can be played by the hygroscopicity of the materials from which it is made. Water first absorbed into the shingles, and then already, with colds, inside it will freeze. After several similar cycles, the brittle material will begin to break down. For the warm countries of Europe, this is not so scary, but for Scandinavia and Russia it can be a problem.

If the coating is scratched, the metal tile will rust.

In fact, the polymer coating that is applied to sheet steel has a fairly high resistance to mechanical stress. This applies to the budget polyester, and to a very strong polyurethane. That is why surface scratches do not violate the integrity of the coating. And if it does, steel will remain a protected primer, an anti-corrosion layer and a zinc coating. The blame for corrosion on the roofs with metal tiles is to be laid not on bad material, but on unscrupulous assemblers. By the rules, in no case it is impossible to cut the steel coated with an ordinary Bulgarian. After all then in a place of a cut a protective layer burns out, and flying sparks will spoil it in the neighborhood. To properly cut the metal, you need to use either cut-through shears, or a special attachment to the drill. This is constantly mentioned by all manufacturers in their instructions, but not all masters pay attention to this. It is worth remembering that, after cutting the leaves, the edging edges need to be tinted, which also applies to scratches made by negligence. Corrosion may also appear when using self-tapping screws during the fixing of the roof, is not intended for this at all. After all, they should have a protective coating and EPDM gasket.

Metal tile

Mount metal is difficult.

Experts argue that this occupation in skilled hands will not take much time.The fact is that the metal tile is not a set-up coating, it must be laid in whole sheets. In the summer, this will be done faster than in the case of bitumen-based materials. After all, they begin to swim because of the heat intolerable for them. So it is necessary to work only in the morning and in the evening, which in the case with metal roofing is excluded.
