The different types of roof terrace fit-out in Belgium

Depending on the configuration chosen for the roof terrace of your home in Belgium, the cost can vary significantly. Each type of design has its own advantages and specific characteristics.

Accessible and non-accessible roof terraces

The accessible roof terrace requires work to create a passage from the inside of the home.
The surface must be covered with a coating capable of supporting the weight of installations as well as regular passage.
The floor can remain in raw concrete, but for more comfort, one can opt for tiling, wooden planks, natural stones, etc.
You can also green it by integrating a garden, plants, flower beds, or a lawn in Belgium.

The non-accessible roof terrace, on the other hand, has a simpler structure accompanied by a waterproofing membrane.
Unlike the accessible roof, it cannot serve as a living space, as no internal access is provided.
However, it is possible to install ventilation, a smoke outlet, or heating-related elements.
One can also consider greening it to improve the thermal insulation of the roof in Belgium.

Landscaping vs functional fit-out

The landscaping aims to create a pleasant and decorative space.
The professional then uses plants, flowers, shrubs…
He can also install synthetic grass or outdoor furniture.

The functional fit-out, on the other hand, maximizes the practical use of the roof terrace in Belgium through various arrangements.
It can include a terrace slab, outdoor lighting, a cooking area, or other installations that allow the roof to be used for specific activities.

Essential steps and considerations in the fit-out of a roof terrace in Belgium

When creating a roof terrace in Belgium, the main steps involve the waterproofing and insulation of the roof.
Other key elements include safety, the installation of a guardrail, shading solutions, and the choice of suitable furniture.

Factors influencing the cost of a roof terrace in Belgium

Several elements can affect the price of a roof terrace fit-out in Belgium.
To precisely identify those that concern your project, it is recommended to consult a specialist like Avenir Rénovations to obtain a personalized quote.
However, keep in mind that the main parameters likely to impact the final amount are: the chosen materials, technical constraints, as well as the size and configuration of the roof in Belgium.

These two aspects play an important role in the overall cost.
A larger area requires more materials (covering, structural elements, etc.) and results in a higher rate for waterproofing.
It also requires a longer intervention time and a larger workforce, which increases the price charged by the professional in Belgium.

The configuration of the roof and its geometric complexity can also lead the craftsman to increase the rate.
Indeed, these particularities make the work more demanding and require additional interventions in Belgium.

The materials used strongly influence the cost of a roof terrace in Belgium due to the varied needs of each project.
Depending on whether you choose a wood, tile, concrete, or other type of covering, the price will be directly affected.

If your project requires premium products or materials that require more elaborate technical installation, the rate may also be adjusted.
It is therefore essential to choose your materials in Belgium based on your budget and the desired performance.

These constraints encompass obligations related to construction, urban planning, or applicable engineering standards in Belgium:

  • seismic regulations,
  • thermal insulation rules,
  • maximum load requirements, etc.

These parameters influence the cost of a roof terrace in Belgium, as they condition the choice of materials and the design of the project.

The necessary permits and authorizations can also increase the cost, as they incur expenses related to compliance.
To avoid delays, unexpected expenses, and unforeseen events, work with the teams at Avenir Rénovations, who are well acquainted with Belgian regulations.
