Types of Roofing Materials | JP Construction London

When it’s said “roof”, means a loose roof in a building, made of anything, and there is NO concrete slab that can be used by humans and it’s provided by jp Construction Sevice Roofing Greenwich. Let’s start with a well-kept secret, which will give you a quick natural understanding of how a roof solution works: The lowest slope will mean the technical roof, and the higher slope the low-tech roof. ”To understand the process, let’s start with one of the most basic types of roofing systems: thatched roofs. The grass roof mostly will have a slope of 45 degrees or more. This is because there is not much water. However, they are thick, usually 400mm (16 ”) anyway.

On the other hand, a state-of-the-art system such as a sloping slope of a steel plate can be placed on slopes of 1 degree or less, as it is completely waterproof.

In addition to waterproofing, the roof must perform other functions: it must support snow, look attractive, must have a permanent anti-ageing finish, must not absorb heat in hot climates, and must not allow heat in cold climates.

The roof must be able to withstand the following loads:

Air cargo, which can be very large in some areas

  • Loads of people (if the roof is not accessible, it should be able to withstand the weight of maintenance personnel)
  • Loads of ice
  • Earthquakes

Thatched Roof

A thatched roof is been given extra layers of grass protection.

It is one of the first man-made roofing systems and is still used by millions of buildings worldwide. Made of dried plant stems, the grass roof will have a slope of 45 degrees and a thickness of 400mm (16 ”). This thickening is done by several layers of fibers of each plant. When waterfalls on a grass roof, it will drip from layer to layer as gravity pulls down. So the thickness creates enough layers of water droplets to flow smoothly out of the building before it enters the room. A steep slope works to increase the speed of the droplets so that they come out of the building quickly before falling inside. So this type of roof is very different from other roofs, as it does not have a single waterproof skin, but instead has a lot of waterproof layers.

Foundation Roof

Slide roofs are installed over wooden bands.

Slate or Roofs: stone is not the largest thing on the roof, as it is heavy. Slate is a type of natural stone that breaks into smaller layers if you use a chisel. This produces small, waterproof tiles that can be spread out to form a roof. Since stone tiles are not the same size, this is not a very wet system. It is therefore needed to have a good slope, 20 to 30 degrees, forcing water to run through the roof and not drip into the gaps.

Indigenous Clay Tile Roof

Clay Tiles: Clay tiles are a traditional type of Roofing Greenwich material. Clay is a widely available and easy-to-use form into lip-shaped water flow channels. It is still widely used in many parts of the world, and it looks good.

Wood Timber: Wood timber is light and easy to replace, and it is widely used in many parts of the world. A corrugated iron sheet is inexpensive and quick to install.

Metal Roofing Systems: Metal roofing systems are very popular in modern times. They are used in almost all industrial buildings and airports and can also be used in residential and educational buildings. They made a very light, durable, economical, and waterproof roof, and came in a wide variety of designs. The most commonly used metals are mild steel, aluminum, and stainless steel. Metal roof sheets need protection from corrosion, and they are usually covered with tile or covered with other layers of protection. The sheets are very small, up to 0.5mm for steel, and 1mm for aluminum. They, therefore, need to be separated from other layers to be installed on the roof.

Asphalt Shingle Roofing: Are small sheets of rubber that are cut to make them look like clay or stone. They usually adhere to the ground with adhesive, or with hot bitumen.
