Pärein

Pärein is a Finnish term that refers to a type of wooden shingle or shake used for roofing and siding. These are traditionally made from split or sawn pieces of wood, typically pine or spruce, chosen for their durability and resistance to weather. The process of creating pärein involves splitting logs into thin, uniform pieces, which are then often treated with natural preservatives like tar or linseed oil to extend their lifespan.

Historically, pärein was a common roofing material in Finland due to the abundance of suitable timber and the material's suitability for the local climate. Wooden roofs offered good insulation and were relatively easy to repair. The characteristic appearance of pärein roofs, with their natural wood grain and earthy tones, is a distinctive feature of traditional Finnish architecture.

In modern times, while other roofing materials like metal and asphalt have become more prevalent, pärein is still used in the restoration of historical buildings and in new constructions seeking a traditional aesthetic. The production of pärein is a craft that requires skill and knowledge of wood properties. The installation process involves overlapping the shingles to create a watertight surface, with a specific pattern and angle to ensure effective drainage. The longevity of a pärein roof depends on the type of wood used, the quality of craftsmanship, and regular maintenance, which may include re-treatment with preservatives.
