Slates, roof tiles and wall copings
Roof tiles, slate and wall copings are quite common products on the reclamation market. They come in a broad range of different colours, dimensions and shapes, with the appearance varying according to the production region. Slates are less frequent in Belgium and the Netherlands, but they are commonplace in other parts of Europe with a long history of slate extraction (e.g. Wales, the south of France, etc.).
The manufacturer’s name appears on the back of some roof tiles. When looking for a dealer to reclaim a batch of roof tiles, it is useful to communicate this information to assess the reuse potential of said batch.
Roof tiles come in different ranges with different finishes: some keep their clay appearance; others are varnished or enamelled. Some popular models:
- Boom tiles (frequent in Belgium)
- storm tiles: they allow double (and sometimes even triple) interlocking
- flat tiles
- round tiles (more characteristic of French regions).
Ceramic wall copings come in different formats: straight or angled. They also exist in other materials such as stone, terracotta…
Prices vary according to the tiles types and regions. As an indication, in Belgium, common types such as Boom tiles are sold at around 20 €/m² while rarer models (such as like black tiles, known as blauwgesmoorde) are sold at around 35 €/m².
For wall copings, prices are in the region of 25 €/unit (excl. VAT).
Did you know?
The life span of roof tiles depends on their intrinsic characteristics, as well as their orientation and the weather conditions to which they are exposed during their initial usage phase. Basic tests make it possible to identify poorer-quality roof tiles:
- the colour (a darker tile is better fired and therefore more resistant to frost).
- the sound they produce when tapped (a dull sound indicates high porosity or a crack).
- how easily they crumble when scratched.
- how quickly they absorb a small amount of water.
- the presence of foam is also an indicator of high porosity.
- roof tiles from barns often crumble easily due to contact with nitrogen and sulphur emissions.
