There are actually distinct advantages and drawbacks to utilising each type of roofing system for the home, however, let's start with a properly-kept secret, one who will give you a fast understanding over the range of roof solutions:
The slope of the roof serves as a distinct indicator concerning how hi-tech the roof is. An extremely low slope means a hi-tech roof, along with a high slope a decreased-tech roof.
To comprehend this basic principle, why don't we get started with one of the most low-tech roofing systems: a thatch roof. Thatch roofs in the majority of countries could have a slope of 45 degrees or more. This is mainly because they are not too watertight. However, these are rather thick, regularly 400mm (16") or thereabouts. Hence the high slope forces the water to work off before it penetrates throughout the thickness from the thatch, a decreased-tech solution.

Conversely, a cutting edge system for example low-slope "kliplock" corrugated metal sheets can be installed at slopes of 1 degree or less, as it is completely water-tight.
In addition to being water-tight, a roof must perform many other functions: it must support snow, need to be eye appealing, need to have a permanent abrasion-resistant finish, should never absorb heat in hot climates, and must retain heat in cold climates.
Thatch Roofs: are some of the oldest roofing systems developed by man, and are also still used in countless buildings all over the world. Made of dried plant stems, a thatch roof will commonly possess a slope of 45 degrees and thickness of 400mm (16"). This thickness consists of many layers of individual plant fibres. When water falls upon a thatch roof, it will trickle from layer to layer as gravity brings it downwards. So the thickness in fact creates ample layers for the water drops to transfer horizontally out from the structure before they drop in to a room. The steep slope will serve to boost the speed in the droplets, to make sure they swiftly leave the structure before falling inside. So this kind of roof is extremely unique utilizing roofs, mainly because it doesn't have got a waterproof skin.
Slate or Stone Roofs: stone just isn't the greatest material for roofs, because it is heavy. Slate can be a natural style of stone which splits into thin layers in case you strike it employing a chisel in just the ideal manner. This provides thin, water-resistant tiles which might be overlapped to produce a roof. Ever since the stone tiles aren't the identical dimension and thickness, this may not be a system that is highly waterproof. Therefore it has to possess a decent slope, of say twenty to thirty degrees, to produce water to operate from the roof but not trickle from the cracks.
Wood Shingle Roofs: wooden shingles are light and very easily replaceable, and were applied widely in most regions around the world.
Metal Roofing Systems: metal roofing systems are immensely popular in today's times. They are chosen in virtually every industrial and airport terminal building and can also be used in residential and educational buildings. They create for an very light, robust, affordable, and waterproof roof, and can be bought in many varieties. Typically used metals are mild steel, aluminum, and stainless. Steel roofing sheets has to be safeguarded from corrosion, and so are usually galvanized or covered with other protective layers. The sheets are particularly thin, approximately .5mm in the matter of steel, and 1mm in aluminum. They therefore need insulation and many other layers to be incorporated into your roof.
