Why choose or renovate a steel deck roof?
1. Lightness and ease of installation
The steel deck is one of the lightest roofing materials on the market, making it an ideal solution for existing frameworks or lightweight structures. It allows for a quick and clean installation, even on large surfaces.
2. Excellent mechanical resistance
Treated against corrosion, the steel deck withstands impacts, wind, rain, hail and temperature variations. Some models include anti-UV coatings or matte anti-reflective finishes to enhance their durability.
3. Effective waterproofing
In renovation, a well-installed steel deck ensures a perfect waterproofing, particularly thanks to its overlapping joints, ribbed profiles and waterproofing accessories (edges, ridges, drainage strips).
4. Contemporary aesthetics
Available in various colors, finishes and shapes, the steel deck allows for a sleek or architectural look, perfectly suited to modern homes, extensions or commercial buildings.

Insulation and condensation: a crucial point
The steel tray, especially in single skin version, is sensitive to condensation. It is therefore essential to provide:
- A high-performance and continuous insulation
- A ventilation in the underface or between panels
- An internal vapor barrier to limit moisture rise
In renovation, the insulated steel tray (sandwich type) is a very effective 2-in-1 solution.

Frequently Asked Questions – Steel Tray Roofing in Belgium
What is the lifespan of a steel tray roof?
A well-installed steel tray can last 30 to 50 years, depending on the type of coating, climatic conditions, and the quality of maintenance. Double skin models or those with anti-corrosion finish offer superior durability.
Is the steel tray noisy in case of rain?
Yes, in the uninsulated single skin version, the steel tray can generate resonance noises during showers. To remedy this, we offer the installation of an insulated steel tray (sandwich type) or the implementation of a complementary sound insulation system, particularly effective in residential areas.
Is the steel tray compatible with a residential house?
Yes, provided you choose the right type of steel tray (insulated or aesthetic) and meet the requirements for insulation, waterproofing, and aesthetics. Some models tile effect or standing seam integrate perfectly into contemporary residential projects.
Do you need a permit to replace a roof with a steel tray?
This depends on the municipality. If the roof changes appearance (shape, color, type of coating), it may be necessary to declare the work to urban planning. We assist you in checking local regulations before starting the work.
Is the steel tray suitable for low slope roofs?
Yes. Some profiles of steel trays are designed to be installed from 5 to 10% slope, with anti-condensation treatment and reinforced waterproofing accessories. It is therefore ideal for extensions, garages, annexes, or agricultural sheds.
