There are actually distinct positives and negatives to using each form of roofing system to your property, however, let's start with an effectively-kept secret, one which will grant an quick understanding regarding the wide range of roofing solutions:
The slope in the roof serves as a distinct indication concerning how hi-tech the rooftop is. An exceptionally low slope means a hi-tech roof, plus a high slope a low-tech roof.
To completely grasp this concept, we will start with one of the low-tech roofing systems: a thatch roof. Thatch roofs in the majority of countries have a very slope of 45 degrees or more. This is just mainly because they aren't very watertight. However, they are rather thick, frequently 400mm (16") or so. Therefore the high slope forces the water to operate off before it penetrates with the thickness from the thatch, a low-tech solution.

On the other hand, a high tech system such as low-slope "kliplock" corrugated metal sheeting could be installed at slopes of 1 degree or less, because it is perfectly water tight.
Besides being water-tight, a roof will likely need to perform additional functions: it requires to support snow, must look attractive, must have a lasting abrasion-resistant finish, should never absorb heat in hot climates, and should not lose heat in colder climates.
Thatch Roofs: are the earliest roofing systems created by man, and are still made utilization of in countless constructions globally. Consisting of dried plant stems, a thatch roof will in most cases possess a slope of 45 degrees and thickness of 400mm (16"). This thickness is composed of many layers of individual plant fibres. When water falls upon a thatch roof, it will trickle from layer to layer as gravity pulls it downwards. Therefore the thickness the truth is generates ample layers for the water drops to transfer horizontally away from structure before they drop in a room. The steep slope will serve to enhance the speed with the drops, hence they quickly move from the construction before dropping inside. So this style of roof is incredibly distinct utilizing roofs, since it doesn't have got a waterproof skin.
Slate or Stone Roofs: stone just isn't the most significant material for roofs, as it is heavy. Slate is usually a naturally occurring type of stone which splits into thin layers in the event you strike it with a chisel in only the proper manner. This creates thin, water-resistant tiles which might be overlapped to create a roof. Ever since the stone tiles aren't exactly the exact same size and thickness, this isn't a real system which is highly waterproof. Therefore it must possess a decent slope, of say 20 to 30 degrees, for making the water to work off the roof and not seep with the gaps.
Wood Shingle Roofs: wooden shingles are lightweight and extremely easily replaceable, and were made usage of widely in several regions worldwide.
Metal Roofing Systems: metal roofing systems are greatly popular today. They are utilized in just about any industrial and airport terminal building and could also be used in domestic and educational buildings. They make for any extremely light, strong, economical, and waterproof roof, and can be purchased in many varieties. Frequently used metals are mild steel, aluminum, and stainless. Steel roofing sheets have to be shielded from corrosion, and so are usually galvanized or engrossed in other protective layers. The sheets are rather thin, approximately .5mm when it comes to steel, and 1mm in aluminum. Therefore, they want insulation and several other layers to get integrated into the rooftop.
