What do we get by choosing a metal tile roof?

Choosing the right roof is the most important step determining the service life of the entire house. Today, more and more homeowners are choosing a roof made with metal shingles. In addition to easy and quick installation, it competes with other roofing materials with a number of advantages. We will tell you more about them and why metal shingles are the most preferred roofing material.

What is a metal shingle?

A metal tile is an embossed sheet of galvanized steel with a polymer coating. This material is much more durable, reliable and environmentally friendly than its competitors. The appearance of metal shingles is reminiscent of natural shingles. But they differ from them in a number of advantages. For example, being lighter, available in more colors and predisposed by their quick installation.

The metal roof can be installed all year round, even in sub-zero temperatures, while on the other hand bitumen tiles cannot. In addition to being the most popular roofing choice in Europe, metal roofing is known for a number of other advantages.

A wide variety of finishes, thicknesses, colors and designs

Availability of three finishes: gloss, matte and grande matte is another advantage that no other roofing material has. Each one of the three coatings contains a different amount of zinc (between 225-275 grams) per square meter, which together with the thickness plays an important role in the guarantee of the material. Therefore, the higher the zinc content of a sheet, the slower its corrosion and the greater its warranty. As sometimes it reaches 30 years and more.

The thickness of the metal tile is also a property that we should not underestimate. How thick the metal tile is depends on its resistance to bending. Which plays an important role in its delivery and installation. For example, if the sheets for your roof are to be 5 meters long, but you have chosen a material thickness of 0.4mm, installation will be more difficult due to the possibility of individual sheets bending. Today, factories produce metal sheets with a thickness of 0.3 to 0.7 mm.

Manufacturers of metal roof tiles today can satisfy the requirements of even the most demanding buyers. In addition to a variety of coatings and thicknesses, the factories offer a wide range of colors and different leaf wave designs.

Lightweight roof and less load on the house

Metal roof tiles are the most practical choice of material for both new and old roofs. They are particularly suitable for replacing an old roof, because metal tiles are the lightest roofing material. It does not weigh down the roof and does not load the walls of the house. One square meter of sheet metal weighs only about 5 kilograms.

Long service life

The service life with proper installation of the metal roof is 50 years and more. But only if the necessary conditions for roof ventilation are built. Namely, in addition to the membrane, we should also have a built-in double grill for ventilation.

Manufacturer's warranty

All metal tiles that our company sells are issued with a guarantee from the factory itself. The warranty period of the material varies from 10 to 30 years, depending on the coating and thickness of the metal tile. As the 10-year warranty applies to the budget segment.

Resistance to atmospheric conditions

We've all heard that sometimes the cover breaks, peels or flies. But not the metal roof. A risk of peeling when the glue dries exists with bitumen. Due to its installation technology, with the metal roof, there is no risk of peeling when the glue dries, because there is none. While with bitumen this risk is high.

When installing each individual sheet of metal tile, at least 8 special screws for metal-wood with washers are placed. Ensuring that the roof will not fly off.

Another plus of the metal roof is that it cannot be destroyed by hail or the individual sheets crack in extreme cold like natural concrete tiles. Thanks to their composition, metal roof tiles are resistant to all weather conditions.

Competitive price

The price of metal roof tiles not only in Prague, but also throughout Czech Republic attracts more and more owners. Considering its advantages, their price is affordable across the country. Our company offers metal roof tiles in various color ranges, coatings and thicknesses, on which the price of the metal roof depends. More and more homeowners prefer a metal roof for years to come, considering its low cost.

• Metal tiles price: Gloss 0.4 mm - 196 Kč/sq.m.

• Metal tiles price: Matt 0.6 mm - 290 Kč/sq.m.

• Metal tiles price: Grande Mat 0.5 mm - 335 Kč/sq.m.

Disadvantages of metal roof tiles

In addition to all the advantages of metal tiles, we must also pay attention to their disadvantages. A large part of them, we can call requirements for proper installation.

Mandatory slope

The slope of the roof is an important characteristic that affects the choice of roofing material. The minimum slope of the roof with the metal tile must be at least 12%, so that in case of rain or snow, the water can be drained off. If there is not enough slope, it is impossible for the water to drain. Remaining on the roof in the form of small puddles that cause the metal coating to rust.

Breathable roof

When it is said that "the roof must breathe", this means that the roof structure must allow for effective ventilation and drainage of moisture. This is achieved by using special technology materials in the construction and maintenance of the roof to prevent the accumulation of moisture and water vapor that can cause damage such as mold and rotting of the wooden elements of the roof. A key element in this system is the under-roof foil, which is vapor permeable and provides good waterproofing. It allows the moisture from the wood and household water vapor to drain away, thus keeping the roof dry. At the same time, the foil protects against water penetration from the outside. Technically, these foils are designed to be resistant to various atmospheric influences and provide long-lasting protection to the roof structure. Thus, the "breathing" of the roof is key to preventing moisture-related problems and increasing the life of the roof structure. This is particularly important where repairs or replacements are being made to old roofs, as proper insulation and ventilation are essential to the long-term stability and functionality of the roof. In addition to laying a membrane, the installation technology also includes a mandatory double grid. Its construction is neither complicated nor difficult. It will increase the cost of the lumber, but it will be a minor expense compared to the benefits it provides. However, many owners neglect the double grill, not realizing how much it increases the life, not only of the roof, but of the entire structure.

Noise insulation

Metal shingles can be noisier during rain or high winds than other types of roofing materials. But this shortcoming can be easily eliminated. By using an additional coating, also known as DRIP STOP. It is a synthetic coating that is attached to the inside of metal roof tiles. By providing good sound absorption and additionally protecting the roof from condensation.

Thermal insulation

Metal roof tiles usually offer poorer thermal insulation properties compared to other types of roofing materials. For this reason, it is important that the metal roof has thermal insulation installed, which plays an important role in the overall energy efficiency of the building. It not only improves building comfort in winter and summer, but also helps reduce heating and cooling costs. Properly performed insulation can not only reduce heat loss, but also reduce noise insulation with metal tiles.

Correct installation of the roof

Even if you choose the best and most reliable roof, improper installation can lead to serious problems and costs in the future. A major part of the installation depends on the right choice of contractor. For this reason, it is important to choose a reliable and professional contractor who has the necessary professionals familiar with the relevant roofing material.
