A shingle roof is composed of around 65 cm long spruce boards. These are covered four times, which means that only about 16 cm of a shingle is visible. The shingles are produced by local companies of wood from the Grindelwald forests and the roof are covered in traditional craftsmanship. Therefore the shingled roof is one of the most ecological and sustainable roof types and with a lifespan of 40-50 years it can also compete with the other materials. The shingle roof is part of the village-scape of Grindelwald and its construction is supported by various institutions in order to balance the price difference to other roofing materials.
