There are clear advantages and drawbacks to using each style of roofing system for your house, however, let’s begin with a highly-kept secret, the one which will provide an immediate understanding over the range of roofing solutions:
The slope from the roof serves as a clear indicator regarding how hi-tech the roofing is. A very low slope will mean a hi-tech roof, and also a high slope the lowest-tech roof.
To completely grasp this idea, why don’t we start with one of the low-tech roofing systems: a thatch roof. Thatch roofs in nearly all countries could have a slope of 45 degrees or so. This is certainly because that they are not so watertight. However, they may be really rather thick, frequently 400mm (16″) or so. So that the high slope forces this type of water to work off before it seeps via the thickness from the thatch, a small-tech solution.
On the other hand, a state-of-the-art system such as low-slope «kliplock» corrugated metal sheets could be installed at slopes of 1 degree or less, since it is completely watertight.
Apart from being watertight, a roof must perform other functions: it must have to support snow, need to be eye appealing, should have a lasting abrasion-resistant finish, must not in hot climates, and must not lose heat in colder climates.
Thatch Roofs: are one of the earliest roofing systems made by man, and are still utilised in scores of buildings across the world. Made from dried plant stems, a thatch roof will frequently have a slope of 45 degrees and thickness of 400mm (16″). This thickness consists of many layers of individual plant fibres. When water falls onto a thatch roof, it would trickle from layer to layer as gravity pulls it downwards. Hence the thickness the truth is generates enough layers to the water drops to move horizontally outside of the structure before they get caught in an area. The steep slope will help to accelerate the pace of your droplets, so they quickly leave the construction before falling inside. So this sort of roof is very distinct from other roofs, simply because it doesn’t have got a waterproof skin.
Slate or Stone Roofs: stone just isn’t the highest material for roofs, because it is heavy. Slate can be a naturally sourced type of stone that splits into thin layers should you hit it using a chisel in the optimal way. This gives thin, water-resistant tiles that can be overlapped to make a roof. Since stone tiles aren’t precisely the same dimension and thickness, this just isn’t a process that may be highly waterproof. Therefore it will take a reliable slope, of say 20 to 30 degrees, to create this type of water to work away from the roof but not seep through the gaps.
Wood Shingle Roofs: wooden shingles are light-weight and really easily replaceable, and were employed widely in numerous regions of the world.
Metal Roofing Systems: metal roofing systems are hugely popular today. They are used in virtually every industrial and airport terminal building and may also be employed in residential and academic buildings. They make for any incredibly light, robust, inexpensive, and waterproof roof, are available in most varieties. Widely used metals are mild steel, aluminum, and stainless. Steel roofing sheets have to be safeguarded from corrosion, and so are typically galvanized or coated with some other protective layers. The sheets are particularly thin, as much as .5mm in the matter of steel, and 1mm in aluminum. Therefore, they will need insulation as well as other layers to be incorporated into the rooftop.
