Why a slate roof?

Slate is a natural material that offers unparalleled durability. It withstands frost, UV radiation and mechanical stress decade after decade. Slate's natural colour and texture give the roof a unique and prestigious appearance that no industrial material can replicate.

Types of slate

The most commonly used slates in Finland come from Spain, Wales and Norway. Slates of different origins vary in colour (grey, dark, greenish) and properties. Spanish slate is the most affordable, while Welsh slate is considered the finest in the world. Small quantities of domestic slate are quarried in Kainuu.

Slate roof price

The price of a slate roof is typically 120–250 €/m². The high price is due to the quality of the material and the fact that installation requires specialist expertise. Each stone is installed by hand. Thanks to its long lifespan, the annual cost is nevertheless competitive with cheaper materials.
