Why choose Avenir Renovations?
Why renovate a tile roof?
1. Preserve waterproofing and structure
Damaged or displaced tiles can allow water to pass through, leading to:
- Infiltrations in the attic
- Degradation of the thermal insulation
- Risk of mold and efflorescence
- Deterioration of the wooden framework
Renovation allows for a complete restoration of the roof's waterproofing and to intervene on structural elements if necessary.
2. Prevent tile falls
Frost, wind, or aging can cause displacement or breakage of tiles, posing a risk to the safety of occupants and passersby. Regular diagnostics and preventive intervention can avoid these inconveniences.
3. Enhance property value
A renovated roof improves the overall aesthetic appearance of the house and increases its resale value. This is an important argument for energy performance, comfort, and safety of the home.

Insulation and ventilation: an essential complement
During the renovation of a tile roof, it is often relevant to consider external insulation (sarking), especially in the case of heavy renovation.
This allows for:
- A significant improvement in thermal performance
- Optimization of summer and winter comfort
- Durable energy savings
A proper ventilation (2 cm rule, ventilation tiles, ridge vents) is also essential to avoid condensation in the attic.

Frequently Asked Questions – Tile Roofs in Belgium
When should a tile roof be renovated?
A renovation is recommended when you notice:
- Leaks or infiltrations under the roof
- Broken, displaced, or missing tiles
- Excessive moss or vegetation
- Roof sagging or a weakened structure
- Absence of an underlayment, especially in older homes
A site diagnosis is essential to determine whether it is a localized repair or a complete renovation.
Do all tiles need to be replaced?
No. If the roof covering is generally in good condition, it is sometimes possible to only replace the defective tiles. However, in the case of old, porous tiles or if the structure is weakened, it is preferable to opt for a complete refurbishment, which is more durable and cost-effective in the long run.
Can old tiles be retained during a renovation?
Yes, if they are still in good mechanical and aesthetic condition. It is possible to carefully remove them and then reinstall them after renovating the support. This helps maintain the original appearance, especially in areas subject to urban planning regulations.
What is the lifespan of a tile roof?
- Clay tiles: about 40 to 60 years, sometimes more if well maintained
- Concrete tiles: about 30 to 40 years
The lifespan also depends on exposure, quality of installation, and maintenance.
What assistance can be obtained for a roof renovation?
In Belgium, certain regional aids (energy grants, PEB renovation) may be available, especially if you include thermal insulation in your project. We will assist you in checking your eligibility in Wallonia, Brussels, or Flanders.
