Clay tile - a solid and heavy covering. Also it is a lot of manufacturers in the Europe. Service life very big. In Old Riga houses with a tile roof which already more than 100 years till now cost. The tile does not change the color on the expiration of time. The tile "breathes" as is a natural product, the condensate harming wooden designs therefore does not accumulate. As the concrete tile is widely used, she those so is durable, but it is easier than clay. A tile roof heavy enough (42-55kg/m2), therefore bearing designs should be from a material with thick section - however this minus often consider from the positive point of view as the heavy roof well presses on a design of the house.
