Different Roof Types Of Sloped Roofs
A sloped roof should have a strong water-resistance capacity. Besides, it should protect the building from snow, contain a stable abrasion-resistant finish, not engross heat in scorching climate, not release heat in cold weather.
A roof should have the adequate strength to resist the following loads:
- Wind loads (it can be very high in some regions)
- Human loads (if the roof is not convenient, it should have the ability to bear the weight of maintenance workers)
- Snow loads
- Earthquake
Different Roof Types Of Sloped Roofs
Thatch Roofs:
These types of roofing systems are extensively utilized in several structures all through the world. It is built with dried plant stems and normally comprises a slope of 45 degrees and thickness of 400mm (16"). This thickness is formed with a number of layers of separate plant fibers. If the water is poured on a thatch roof, it will flow from layer to layer since gravity draws its downward direction. Therefore, the thickness effectively develops adequate layers for the water drops to pass on horizontally beyond the structure prior to drop into a room. The purpose of the steep slope is to raise the speed of the drops, with the intention that they rapidly go away from the structure prior to going down inside. Therefore, that roof comprises of a huge number of partially waterproof layers instead of a single waterproof skin.
Slate or Stone Roofs:
Due to heavyweight, the stone is not recommended to be used as material for roofs. Slate belongs to a naturally generated type of stone that is divided into thin layers after being hit with a chisel in a proper manner. It creates thin, water-resistant tiles which are overlapped to build up a roof. As the size and thickness are not uniform, this type of roof is not greatly water-resistant. So, there should be a good slope of 20 to 30 degrees, to drive the water to clear off the roof and not flow through the gaps.
Clay Tile Roofs:
Clay tiles belong to a normal type of roofing material. Clay can be easily accessible and transformed into various forms which contain lips and channels to lead the flow of water. It is mostly recognized in several parts of the world as the tile has strong resistance capacity against wind and moisture, and provides a long-lasting roofing option – could be last for 80 years or longer.

Wood Shingle Roofs
Wood shingles stand for thin, tapered pieces of wood which are commonly utilized to cover roofs and walls of buildings to safeguard them from the weather. Wooden shingles are light in weight and can be mostly found in several parts of the world.
Metal Roofing Systems:
In recent times, the metal roofing systems are gaining popularity. They are mostly found in every industrial and airport terminal building as well as in residential and educational buildings. They are used to create a very light, strong, economical, and waterproof roof, and available in a very wide range of varieties. Different types of metals like mild steel, aluminum, and stainless steel are used to develop this type of roof. Steel roofing sheets should be defended from erosion, and are generally galvanized or coated with other preventive layers. The sheets are relatively thin, as much as 0.5mm for steel, and 1mm for aluminum. They, therefore, need insulation and other layers to be combined into the roof.
Asphalt Shingle Roofing:
Asphalt shingles mainly belong to thin rubber-like sheets that are cut to appearance as clay or stone shingles. They are normally attached to the under-surface with an adhesive, or with hot bitumen.
