There are clear pluses and minuses to utilising each kind of roofing system for your residence, however, let's start out with an effectively-kept secret, the one that will provide you with a quick understanding over the wide range of roof solutions:
The slope of your roof can be a distinct indicator of methods hi-tech the roofing is. An incredibly low slope indicates a hi-tech roof, along with a high slope a small-tech roof.
To completely grasp this principle, permit us to begin with one of the more low-tech roofing systems: a thatch roof. Thatch roofs in a large number of countries could have a slope of 45 degrees or so. The reason being they aren't very watertight. However, they are really rather thick, quite often 400mm (16") or so. So the high slope forces this type of water to operate off before it seeps from the thickness from the thatch, a decreased-tech solution.
Alternatively, a top tech system for example low-slope "kliplock" corrugated metal sheets may be installed at slopes of 1 degree or less, since it is perfectly water tight.
Besides being watertight, a roof will need to perform other functions: it needs to support snow, must look attractive, need to have an extended lasting abrasion-resistant finish, should never in hot climates, and should not lose heat in cold climates.
Thatch Roofs: are some of the earliest roofing systems made by man, and are also still utilized in countless structures globally. Made up of dried plant stems, a thatch roof will often have a very slope of 45 degrees and thickness of 400mm (16"). This thickness is made of many layers of individual plant fibres. When water falls onto a thatch roof, it would trickle from layer to layer as gravity brings it downwards. So the thickness in fact creates enough layers for that water drops to advance horizontally away from structure before they drop to a room. The steep slope will help to increase the speed of the drops, therefore they quickly move out of the construction before falling inside. So this kind of roof is quite unique off their roofs, since it doesn't have a waterproof skin.
Slate or Stone Roofs: stone is just not the most significant material for roofs, as it is heavy. Slate can be a natural sort of stone which splits into thin layers when you strike it having a chisel within just the right manner. This produces thin, waterproof tiles which may be overlapped to form a roof. Since the stone tiles usually will not be exactly the same dimension and thickness, this just isn't a system which happens to be highly waterproof. Therefore it should have a great slope, of say twenty to thirty degrees, for making the liquid to move from the roof rather than seep from the cracks.
Wood Shingle Roofs: wooden shingles are lightweight and extremely easily changeable, and were employed commonly in lots of areas worldwide.
Metal Roofing Systems: metal roofing systems are greatly popular today. They can be chosen in nearly every industrial and airport terminal building and may be used in residential and academic buildings. They manufacture for an incredibly lightweight, robust, economical, and watertight roof, and come in an exceedingly wide range of varieties. Typically used metals are mild steel, aluminum, and stainless steel. Steel roofing sheets should be shielded from corrosion, and therefore are typically galvanized or covered with other protective layers. The sheets are somewhat thin, approximately .5mm in the case of steel, and 1mm in aluminum. They therefore need insulation and various other layers being integrated into the roof.
