The reinforced concrete roof is constructed similarly to reinforced concrete floors and can be solid, lightweight. The roof slabs are reinforced with steel rods often in both directions, the longest rods are clear and be embedded in the walls of at least 100 mm. Usually the slab is finished horizontal and the slope is obtained with a template, possibly with a slight addition to improve the thermal insulation. Vents can be installed to remove trapped air and moisture from below the roof covering.
Palm roofs (Sloping roof)
Palm roof is mainly used in places with hot and humid climate. This material is very useful for its waterproof qualities and has the ability to, allow effective ventilation and it is also abundant, economical and easy to use.
Roofs made of beams and foundation boards

Clay tile roof
This type of roof is very suitable for moderate climates, whether wet or dry. Its construction is simple and inexpensive; the materials involved are annealed clay tiles, which should be of uniform and homogeneous nature, should have no cracks and can be natural or painted.
They are constructed by placing wooden beams on two end walls with proper slope and variable partitioning (50 to 80 cm) between the beams, depending on the size of the brick to be placed. The beams remain seated and locked in place by filling the gaps between them and the wall, with a mixture of lime-sand concrete.
Tile roof made of asbestos cement
In this type of roofing, slates made of asbestos cement are used for making the roof. This cement, which is actually a mixture of cement & asbestos, forms a material which is very hard and is ideal to be used as roofs in people’s houses. However, these roofs do not last as long as other roofs after certain years, you will need to replace them as they can become hazardous to people’s health. These roofs are easy to clean and they can be used in all kinds of weather as they can keep the house at a moderate temperature.

However, they are ideal for places like Seattle where the weather is pretty moderate and the temperature is never extreme in summer or in winter.
Mixed structure roofs
