They are commonly made of cedar, but can also be made of other rot resistant woods, such as redwood. Wood gives a natural look but it has a short lifespan and requires periodic maintenance.
Wood shakes or wood shingle roofs require fireproof treatment and are not recommended for fire-prone regions.
These durable synthetic roofing shingles can be recycled when replaced. They require little maintenance but do not provide as much thermal insulation as other alternatives.
Regarding fire resistance, some of these synthetic products require the installation of a special underlayment to obtain a Class A Fire Rating, so we must be aware of which product we are going to install.
They are made of clay that is heated to very high temperatures in large kilns. Although they come from a natural raw material, their production process requires a lot of energy. Large amounts of CO2 are released in their manufacture with a consequent negative impact on the environment.
Once placed on the roof, they require little maintenance and can have a long life under normal conditions. However, they are quite brittle and can break if they are subjected to impact. They are also somewhat more expensive than wood or metal.
Although the most common are Pan and Roman tiles, clay tiles are now available in a variety of shapes that can mimic other materials such as slate tiles.

Normally use for flat roofing, this material is lightweight and provides an inexpensive way to waterproof a roof. On the contrary roofing felts are vulnerable to damage and usually they have a short lifespan.
Slate is one of the oldest roofing materials. The value of natural slate lies in its impermeability, durability and versatility.
A good quality slate roofing is very durable and will out-perform better than other roofing materials. Besides, roofing slates are fireproof (class A), immune to insects, fungus and any kind of microorganisms. It is the most long-lasting natural building material ever.
A poor quality roof needs constant repair and maintenance, but when good quality slate is used, not only the cost of re-roofing can be effectively discounted, but the repair and maintenance expenses during its lifetime are extremely low.
