You can find clear positives and negatives to using each variety of roofing system for your personal property, however, let's begin with a well-kept secret, the one which provides you with a rapid understanding regarding the range of roof solutions:
The slope with the roof functions as a clear indication of how hi-tech your roof is. An incredibly low slope will mean a hi-tech roof, and also a high slope a low-tech roof.
To understand this principle, why don't we start using one of the reduced-tech roofing systems: a thatch roof. Thatch roofs in most countries will have a slope of 45 degrees roughly. This is because they aren't very watertight. However, they are really rather thick, frequently 400mm (16") approximately. And so the high slope forces the liquid to operate off before it enters with the thickness from the thatch, the lowest-tech solution.

Alternatively, an increased tech system like low-slope "kliplock" corrugated metal sheeting is often installed at slopes of 1 degree or less, because it is perfectly watertight.
As well as being watertight, a roof must perform additional functions: it needs to support snow, must look attractive, will need to have a permanent abrasion-resistant finish, should never absorb heat in hot climates, and must not lose heat in cold climates.
Thatch Roofs: are probably the earliest roofing systems designed by man, and are still found in countless buildings worldwide. Comprising dried plant stems, a thatch roof will frequently have a very slope of 45 degrees and thickness of 400mm (16"). This thickness is comprised of a number of layers of individual plant fibres. When water falls onto a thatch roof, it is going to trickle from layer to layer as gravity brings it downwards. So the thickness basically creates ample layers for the water drops to shift horizontally from the structure before they drop into a room. The steep slope will help to accelerate the pace of the droplets, so that they can swiftly leave the dwelling before dropping inside. So these kinds of roof is incredibly distinct utilizing roofs, since it doesn't have a very waterproof skin.
Slate or Stone Roofs: stone just isn't the ideal material for roofs, as it is heavy. Slate is a natural type of stone that splits into thin layers in case you strike it by using a chisel in barely the proper way. This offers thin, watertight tiles which may be overlapped to develop a roof. Because the stone tiles aren't the exact same dimension and thickness, this isn't a process that may be highly waterproof. Therefore it will have to use a decent slope, of say 20 to 30 degrees, to make water to perform over the roof but not seep through the spaces.
Wood Shingle Roofs: wooden shingles are light and really easily changeable, and were applied commonly in several parts worldwide.
Metal Roofing Systems: metal roofing systems are greatly popular today. They may be employed in virtually any industrial and airport terminal building and could also be used in residential and academic buildings. They manufacture for the particularly lightweight, robust, affordable, and watertight roof, and can be found in many varieties. Commonly used metals are mild steel, aluminum, and stainless-steel. Steel roofing sheets must be protected against corrosion, and are frequently galvanized or coated with protective layers. The sheets are actually quite thin, approximately .5mm when it comes to steel, and 1mm in aluminum. They therefore necessitate insulation and extra layers being integrated into the roofing.
