  • The imitation slate or tile steel tray : it is the modern version of the lightweight corrugated iron roof, and which can be improved with an optional anti-condensation felt layer.
  • The single skin steel deck :this is the cover most commonly used for agricultural buildings, for example.
  • The double skin steel deck which includes insulation: this roof is perfectly suitable for an altitude above 1,000 meters, and can therefore be considered as a mountain cover.
  • The carrier steel deck : it includes insulation and sealing support.
  • The standing seam steel deck : this roof is unsuitable in the mountains, but it is on the other hand quite common in the plain. It is appreciated for its aesthetic side, its speed of implementation, its affordable price, but also because it can be suitable for a curved work.

  • Its quick implementation and without great complexity,
  • The ease with which it can be harmonized with different types of constructions,
  • The possibility of using it even when specific standards such as anticyclonic (or para-cyclonic) and paraseismic are required,
  • Adapts to all shapes of slightly sloping roofs,
  • Its great resistance to corrosion, UV, climatic variations, fire, strong winds, humidity and therefore mold and moss,
  • Its exceptional lifespan estimated at a good hundred years,
  • Its ability to meet rigorous climatic requirements,
  • The fact that it is perfectly adapted to a light frame,
  • The possibility of installing it as cladding,

Disadvantages of steel deck roofing

Appreciated for its many advantages, the steel deck roof does have some disadvantages, listed here.

  • Very airtight if the steel deck roof is not galvanized, which leads to condensation problems inside the house or any other building,
  • Can only be installed on a roof with a slope of at least 5% but not exceeding 15%, i.e. low slope roofs (neither flat nor too steep),
  • Sensitive to pollution which promotes wear by oxidation,
  • Does not constitute a good thermal insulator except in the case of steel deck roofs incorporating insulation that protects the habitat from cold and excessive heat,
  • Is not a good acoustic (sound) insulator,
  • Involves the application for a building permit,
  • May be prohibited by local planning regulations,
  • Can be a source of discomfort in the event of torrential rain or hailstorms because the sound of drops or hailstones falling on the roof can be amplified. This is enough to disturb the tranquility of the occupants, especially in the rooms located just under the roof.

A simple sheet metal roof for a shed that imitates tile costs on average €18/m². For information, for a single skin steel deck roof, it is necessary to count between 19 and 23 €/m², from 30 to 36 €/m² for a standing seam steel deck roof and from 45 to more than 80 €/m² for insulated sandwich panel. These prices are out of pose.
