When the question arises of what kind of roofing to purchase, it is important to remember that the material should last not one or two years, but several decades. This article will talk about how and which metal tile to choose, paying attention to the various characteristics of the material.
roofing material should be chosen carefully and with great care.
Despite the fact that a metal tile may seem like a rather simple product, its quality depends on a number of parameters and characteristics, which will be discussed in more detail in the article.
The most important performance indicators of metal roofing are:
- Durability;
- Aesthetic appearance;
- Material cost.
Manufacturers of metal tiles
So, metal tile - which one to choose? How well-known the manufacturer or brand of the material depends not so much on its prestige, but on the quality that creates its name.
The difference in cost between metal tiles of little-known or completely unknown manufacturers and metal tiles of well-known brands, which is about 5-10%, primarily guarantees such advantages as:
- High-quality materials used in the production of metal tiles;
- Modern production equipment;
- Responsibility of the manufacturer for the products manufactured by him.
Little-known manufacturers quite often operate on the market for a short time, after which they disappear without a trace, as a result of which, in the event of various troubles associated with the roofing material produced by them, there is simply no one to turn to under warranty, unlike well-known manufacturers who have been working on the market for many years. decades.
When thinking about which metal tile to choose, you should pay special attention to the labeling of its sheets, which differs for different manufacturing plants.
The name of the factory and the date of manufacture of metal tiles are usually applied to the edge of the sheet.
In addition, before choosing the right metal tile, you should clarify the complete list of its components. In the case of a fairly short list, you should not be lazy and spend your time figuring out how unnecessary the missing items are.
Quite often, in practice, buyers find out that any necessary ingredients were excluded from production after purchasing the material, having encountered problems during its installation.
Important: well-known brands are characterized, in addition to an extensive composition of components, also by a complete set of various accessories, and they consider the metal tile itself as a roofing system.
Parameters of steel sheets of metal tiles
Sheet thickness. Steel sheets are the basis of metal tile material. In most European countries, the minimum allowable thickness of a sheet of metal for covering the roof of a residential building is 0.5 mm.
In Russia, a number of suppliers offer material with a sheet thickness of only 0.4 millimeters - such material can only be used when covering objects such as:
- Small buildings (household, household, etc.);
- Sheds;
- Visors.
Useful: in the assortment of the roofing market there are also materials whose thickness exceeds 0.5 mm. An example is the Classic profile manufactured by Rannila.
Part roof coverings metal tiles should include:
- Passivating layer;
- primer layer;
- polymer coating.
The most common drawback of metal tile material is the absence of a primer or a passivating layer, which causes a significant reduction in the service life of a decorative roofing up to 1-3 years.
At present, on the roofs of many buildings built in recent years and covered with metal tiles without one of the required layers, the coating has already peeled off, and rust has appeared on the roof.
Important: In order to make sure that all the required layers are included in the metal tile, the seller must provide a sample of the material that can be broken for visual inspection.
The main types of external polymer coating today are the following:
- Pural;
- Polyester;
- Polyester matte;
- PVDF;
- Plastisol.
The performance, color fastness and durability of all these coatings vary.
When choosing a metal tile for roofing works It is also important to give special time to guarantee the material. Quite often, sellers assume almost any obligation, but only the guarantee provided by the manufacturer matters.
Let us consider in more detail the main types of polymer coating:
- PVF2 or Pural will bring joy for a long time and cause healthy envy among neighbors. Pural is the most optimal material in terms of cost and performance ratio, and PVF2 provides the coating with the greatest resistance to external influences. Naturally, when choosing both materials, you should choose the most complete set and a more well-known brand.
- Matte polyester is suitable for those for whom it is important that the roof does not shine at all, despite the fact that there is shine on roofs covered with clay tiles, which are an imitation of metal tiles.
- Polyester is a suitable material for those who do not make demands on its reliability. When choosing this coating, it should be understood that most Finnish manufacturers do not guarantee this metal tile as a roofing.
The appearance of the roof being erected is determined by the profiling of the metal tile.In addition to design, various requirements during installation depend on the profile, for example, the pitch of the crate.
Most often, a metal tile is an imitation of a natural tile. The profile of this material can be symmetrical or asymmetrical.
The joining of metal tile sheets during installation depends on the quality of profiling, and for some samples of metal tiles of domestic and foreign production, stripes on the roof are characteristic, which can be seen at certain angles.
Useful: when choosing a profile, it is recommended to ask the seller for photos of roofs covered with this material, it is best to ask a couple of sheets to be joined on the spot.
You should also pay special attention to the apparent absence of transverse and longitudinal joints of the sheets ("solidity" of the metal tile).
Other parameters of metal tiles
In order to choose the right color for a metal tile, a number of factors should be taken into account:
- The design of the building and the landscape of the surrounding area, as well as the taste of the developer;
- Greater heating of dark metal tiles under the influence of sunlight, due to which, in case of improper ventilation, the space under the roof in the attic room will be stuffy and hot;
- On light sheets of metal, pollution is more noticeable.
After the choice of a specific type of metal tile is made, you should choose the right organization from which the material will be purchased. Metal tiles of the same brand and manufacturer can be purchased from different sellers.
When choosing a seller, it is recommended to consider the following factors:
- Low price;
- level of counseling;
- Service;
- Information openness;
- Respectful attitude towards the buyer;
- Individual approach to the client, etc.
If all the listed qualities of the selected company turned out to be at the proper level, you can be sure that this company is competitive and expects a long work in the construction market.
Consequently, the metal tile purchased from this company will last for decades, since the seller is interested in providing a quality product.
The service life of a metal tile is also a very important point.
It should be borne in mind that the quality of its installation directly affects the life of this material, so the ability of the seller to provide its own roofing team that has the appropriate licenses to perform this type of work may be of great importance.
This allows even with self-covering the roof to contact the seller for various consultations and recommendations.
Despite the fact that the metal tile is not a roofing system, but only its covering, its quality and reliability have a direct impact on the durability and attractiveness of the entire roof.
Choosing metal tile material should be carefully, sparing no time for this, so that later you can enjoy the comfort and coziness in the house for a long time.
