You will find distinct advantages and drawbacks to using each kind of roofing system for your home, however, let's get started with a properly-kept secret, one which offers you an instant understanding over the wide range of roofing solutions:
The slope in the roof can be a clear indication of methods hi-tech your roof is. An incredibly low slope means a hi-tech roof, along with a high slope the lowest-tech roof.
To be aware of this principle, allow us to begin with among the most low-tech roofing systems: a thatch roof. Thatch roofs in a large number of countries can have a slope of 45 degrees approximately. This really is because that they are not too watertight. However, they're rather thick, very often 400mm (16") or so. And so the high slope forces this type of water to operate off before it seeps through the thickness with the thatch, a low-tech solution.

In contrast, a advanced system for instance low-slope "kliplock" corrugated metal sheets can be installed at slopes of 1 degree or less, since it is completely watertight.
Other than being watertight, a roof will have to perform additional functions: it must support snow, must look attractive, need to have a lasting abrasion-resistant finish, must not in hot climates, and must retain heat in cold climates.
Thatch Roofs: are one of the oldest roofing systems created by man, and are still utilised in millions of constructions worldwide. Comprising dried plant stems, a thatch roof will in most cases use a slope of 45 degrees and thickness of 400mm (16"). This thickness comprises of numerous layers of individual plant fibres. When water falls using a thatch roof, it will eventually trickle from layer to layer as gravity pulls it downwards. Hence the thickness essentially generates ample layers for your water drops to shift horizontally outside the structure before they get into a room. The steep slope serves to raise the pace in the drops, to be able to quickly leave the building before dropping inside. So this particular roof is very different from other roofs, because it doesn't use a waterproof skin.
Slate or Stone Roofs: stone just isn't the best material for roofs, since it is heavy. Slate is a naturally sourced type of stone that splits into thin layers in case you strike it utilizing a chisel in only the correct manner. This generates thin, watertight tiles which may be overlapped to produce a roof. Considering that the stone tiles usually are usually not precisely the same size and thickness, this isn't really a system that is certainly highly waterproof. Therefore it must have got a decent slope, of say twenty to thirty degrees, to force water to perform over the roof and not trickle with the cracks.
Wood Shingle Roofs: wooden shingles are light-weight and really easily replaceable, and were applied commonly in several regions on the planet.
Metal Roofing Systems: metal roofing systems are immensely popular in modern constructions. These are utilized in nearly every industrial and airport terminal building and may be found in residential and academic buildings. They create to have an particularly lightweight, strong, economical, and watertight roof, and come in many varieties. Commonly used metals are mild steel, aluminum, and stainless steel. Steel roofing sheets have to be shielded from corrosion, and therefore are usually galvanized or coated with other protective layers. The sheets are somewhat thin, approximately .5mm in the matter of steel, and 1mm in aluminum. Therefore, that they need insulation and additional layers to generally be integrated into the rooftop.
