What is better - a metal tile or a professional flooring

When choosing a roof covering for building a house, you should consult a professional who will clearly explain what is best for the roof - metal or corrugated board. Materials have many similar characteristics, and are used in different situations.

What is better - a metal tile or a professional flooring for a roof?

To understand what is better - metal tile or corrugated board, you should understand the advantages and disadvantages of each building material.

The starting material for the production of corrugated board is cold-rolled steel sheet, the thickness of which can vary between 0.5-1.2 mm. The sheet is stamped, giving it a profile shape. The stiffening ribs created in this way make the material particularly durable. To improve the moisture resistance of the profiled sheet, it is coated with a special composition of zinc, aluminum zinc, and polymer. The advantages of this material include such factors:

  • service life up to 50 years;
  • resistance to sunlight, humidity, mechanical damage;
  • affordable price;
  • simple installation;
  • light weight.

Such material is suitable in cases where reliability is required, and appearance does not matter. Often used in the construction of garages, industrial buildings or outbuildings.

The metal tile is made of profiled cold-rolled steel. Sheet thickness up to 0.6 mm. Top layer consisting of aluminum zinc, polymeric pural film, plastisol, polyester and protective varnish. This structure enhances strength. The shape of the metal tile is similar to natural tile.

The advantages of this material include:

  • service life of more than 15 years;
  • excellent choice of colors and textures;
  • the roof of this material can withstand significant mechanical stress.

Not without drawbacks:

  • installation requires a professional approach;
  • mandatory laying of a special layer that protects against the creation of condensate;
  • low level of thermal insulation;
  • roof slope - not less than 12;.

What is the difference between metal tile and corrugated board?

Decking is made from steel of greater thickness, it is resistant to mechanical stress. But it has a smaller protective layer, so it lends itself to corrosive changes faster.

Professional roofers to the question: which is better - corrugated board or metal tiles, give the following arguments:

  1. If a roof made of metal tiles is made in compliance with the technology, then it will last much longer than that made of profiled sheet.
  2. The multilayer structure of the metal tile material has excellent anti-corrosion characteristics.
  3. Decking looks much less impressive.
  4. Metal roofing requires careful installation if the top layer is damaged, the protective properties deteriorate.

Which roof is cheaper: metal or corrugated board?

When comparing the cost of roofing from these materials, it becomes clear that corrugated board comes out much cheaper, both in terms of the cost of sheets and the cost of work.

So, 1 m2 of profiled sheet will cost almost two times cheaper than metal tiles.

What kind of corrugated board to cover the roof?

Decking is divided into three categories:

  • wall is relevant for wall cladding and the construction of fences;
  • roofing up to a millimeter thick, with good bearing capacity and low weight, suitable for roofing;
  • universal suitable for both walls and roofs.

Comparison of metal tiles and corrugated roofing for different items

To conduct a detailed analysis of roofing materials, they are compared according to certain parameters. According to the results of the comparison, the best option for construction is selected. The following characteristics are important:

  • sheet thickness and weight corrugated board is thicker;
  • the composition of the polymer coating of the metal tile is much better;
  • the dimensions of the sheets and the level of complexity of installation; metal tiles are more difficult to install;
  • service life depending on the thickness;
  • soundproofing advantages of metal tiles;
  • fire safety advantages of a profiled sheet;
  • the price of corrugated board is cheaper;
  • the appearance of the metal tile is in the lead.

Each material has many grades with different characteristics.

Disadvantages of metal coatings

Metal roofing is in good demand due to its solid service life, low weight, resistance to the external environment. However, they have disadvantages:

  1. The metal base of such building materials has a high coefficient of thermal conductivity. This creates a lot of problems. The warm surface from below causes the snow layer that forms on the roof to melt, resulting in ice. When it comes off, it damages the protective layer, which leads to the formation of corrosion. Thermal insulation required.
  2. The ability to resonate creates a lot of noise, for example, in rain or wind. Soundproofing required.
  3. Metal surfaces are heated under the rays of the sun, which causes condensation in the space under the roof, which, in turn, provokes decay of the frame elements, consisting of wood. High-quality ventilation or vapor and waterproofing is required.

Criteria for choosing metal tiles and corrugated board

Building materials have certain advantages and disadvantages, have a significant service life, and the choice is guided by a number of criteria:

  1. The price of a profiled sheet is cheaper, but it serves less.
  2. Metal tiles are mounted only when the roof slope is more than 12;, and the profiled sheet is more than 3-6;.
  3. The appearance of the metal tile coating is much more presentable.
  4. Decking has a length of up to 12 m, this is true for large-scale industrial buildings. The metal tile is more suitable for private houses.

Metal tile and corrugated board features, similarities and differences

Both materials are made from metal sheets, but of different thicknesses. Both have a protective layer, but of different composition and thickness.

Installation of a professional sheet is much simpler, and the price is much cheaper, but metal tiles look more aesthetically pleasing and richer.

Comparative table of roofing materials

The comparison results can be presented in the form of a table:

Parameters Decking metal tile
Relevance for a flat roof + -
Lifetime + +
Price ++ +

Appearance + +++

Comparison of metal tiles and corrugated board

Comparing two roofing materials, we can conclude for each specific case: which is better - metal tiles or corrugated board. It depends on the needs and preferences of the building owner. If appearance is important and sound insulation is needed, you should choose the first option. If you want to save money, and mount the roof with your own hands, a profiled sheet is suitable. Any material can be purchased from Almet.
