The majority of houses are covered with tiles. This is because the tile has many advantages: Longevity, strength, resistance and aesthetics. But among the different types of tiles, how can you make the right choice? Because to make or remake its roof is a site that is expensive. And once the tiles are laid, it's for a few decades... so do not be fooled.
Choose your tiles according to the standards
The installation of your roof must be done by a professional who must respect the rules and the conditions of installation relating to each type of tiles. Those are the DTU (Unified Technical Documents) which govern these rules: minimum slope of roof, rate of recovery of the tiles on each other according to the geographical area, etc.
The different DTU 40 relate to the covers that are detailed according to the type of tiles.
For example, DTU 40.11 for slate roofs, DTU 40.21 for clay roof tiles with interlocking or raised slip, DTU 40.25 for flat tile roofs, ect.
DTU 43 concern the waterproofness of roofs.
In addition to the technical know-how, you must respect the rules enacted by your municipality. Depending on the region you may be forced to impose a certain type of tile and color. Inquire at your town hall.
Choose your tiles according to their material
Among the traditional materials most commonly used in tile making are terracotta, concrete and slate. How to make your choice?
- Terracotta tile: Classic and timeless
This is the most common tile.
It is robust and resists winds and shocks. It provides excellent thermal insulation and good impermeability. It is elegant and adapts to all styles and architectures regardless of its shape and color.
In recent years, manufacturers have made great efforts to make it even stronger, more insulating and easier to install.
- Concrete tile: Almost similar to terracotta
It mimics the terra cotta tile but is made of concrete.
It has a very exceptional resistance to UV, frost, pollution. It ensures almost perfect waterproofing of the roof.
But it requires a framework and load-bearing walls solid because it is heavy. And mosses and lichens tend to appreciate its surface to settle. These two major defects have been corrected by concrete tile manufacturers.
- Slate tile: Distinguished and resistant
Slate tile is a natural material.
They are very sturdy and very aesthetic. It ensures good thermal insulation
It offers excellent resistance to mosses and lichens but it can rust which weakens it. Its color does not move almost throughout the decades.
But slate is heavy. The frame that supports it must be able bear its weight.
Apart from this historic trio, you can also find recycled composite tiles and steel tiles. Less used, they nevertheless have many qualities of robustness, aesthetics and especially lightness.
Choose your tiles according to their shape
Flat tiles and canal tiles are very geographically marked. The flat tiles are rather central and north and the south and southwest channel tiles. In fact their shape meets the characteristics of roof structure and roof slope which themselves respond to meteorological constraints.
- The flat tile dresses roofs with steep slopes in windy and rainy climates. She does not fear the snow.
- The tile channel is ideal for low slope roofs and allows rapid evacuation of water during heavy rain showers.
The interlocking tile also called mechanical tile is more waterproof, more wind resistant and more economical. It comes in terracotta or concrete. Depending on its size and shape, it adapts to many regions. Roman tile, it imitates the tile channel. Tile small flat-aspect mold, it competes flat tile.
To choose your tiles, you must take into account:
- of the local urbanism constraints in your commune (PLU, historical monuments, etc) that can impose you shape, color and material.
- The geography and climate of your home: Mountain? Plain? Coastal region? Its climatic constraints will determine the slope of your roof and therefore, the shape of your tiles. This information is included in DTUs.
