Slates, roof tiles and wall covers
Roof tiles and wall covers are common products on the reuse market. There is a broad range of different colours, dimensions and shapes, with the appearance varying according to the production region. There are fewer slates in Belgium and the Netherlands, although they are much more commonplace in other parts of Europe with a longer history of slate extraction (Wales, the south of France, etc.).
The manufacturer’s name appears on the back of most roof tiles. When trying to dispose of a batch of roof tiles, it is useful to communicate this information to the dealers contacted. Some types of reusable roof tile are certainly in demand on the market. The fact that a roof appears to be in good condition does not necessarily guarantee that the roof tiles can be put back into circulation.
Roof tiles come in different ranges with different finishes: Some keep their clay appearance; others are varnished or enamelled. Some popular models:
storm tiles: they allow double (and sometimes even triple) interlocking
round tiles (more characteristic of French regions).
Ceramic wall covers come in different formats: straight or angled.
For roof tiles, the prices vary from 17 €/m² (for Boom tiles) to 34 €/m² (for rarer models, like black tiles, known as blauwgesmoorde).
For wall covers, prices are in the region of 25 €/unit (excl. VAT).
Did you know?
The life span of roof tiles, slates and wall covers depends on their intrinsic characteristics and orientation, as well as the weather conditions to which they are exposed during their initial usage phase. Some completed reports of 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 very high porosity
roof tiles from barns often crumble easily due to contact with nitrogen and sulphur emissions.
