A good roof protects your home from weather, water and wind. Year after year. Scandinavian slate has been used on roofs since the Middle Ages and to this day you can see beautiful slate roofs that are several hundred years old. A living proof that our roof slate is timeless, perpetual and maintenance-free.

Acid rain proof
The roof tile isscrewed or nailed onto wooden laths laid horizontally and vertically, with distances adapted to the size of the roof tile. The laths ensure that the slate roof is well ventilated against the suspended ceiling. Roof tiles from Minera Skifer have pre-drilled holes adapted to the slath distance. See our installation instructions for roof tiles.
Prices vary depending on the type of roof tile and the complexity of the roof (angle, gutter, etc.). The installation of slate slabs including laths costs from around NOK 700 per m2 of roof surface. The slate itself is an additional cost. As an example, Otta square slate in a fixed thickness and with fixing holes costs NOK 1700 per m2 of roof surface, including slate overlap. A slate roof of 100 sqm laid with this type of Otta slate costs a total of around NOK 240,000.
A slate roof laid with Norwegian slate rarely needs repairs due to its high breaking strength and frost protection. It can withstand Norwegian winters and the weight of large amounts of snow. Replacing loose or broken slabs is a simple matter for professionals.
Yes, you can. The snow traps are attached to the laths at the same time as the slate is installed, and in exactly the same way as on roofs with other tile types (Zanda, etc.).
As a rule, it is not necessary to clean a slate roof. If a person lives somewhere where climatic conditions provide a breeding ground for moss, this can be removed from the slate roof for aesthetic reasons. The moss is cleaned away with a broom and water or a high-pressure cleaner.
A well-laid slate roof with slate from Norway is almost eternal and usually lasts longer than the actual lifespan of the building. Minera Skifer’s roof tiles are made of natural stone of solid Norwegian rock that does not weather, and it is therefore very common for old roof tiles to be reused on new buildings.
The traditional method is to finish with a higher ridge stone on one roof surface, creating an overlap that covers the ridge. Ridge fittings in steel are also used on slate roofs, as gutters, snow traps, etc., already break with the old style where only slate is visible. The ridge fitting is attached to a wooden lath on the ridge. The fitting itself must be pre-adjusted in the same profile as the lath it is going to cover.
