Which roofing system is the best choice for your home?

There are clear advantages and disadvantages to using each sort of roofing system for your home, however, let's begin with a well-kept secret, one that will provide you with an immediate understanding regarding the range of roof solutions:

The slope of the roof provides a clear indicator of how hi-tech the roof is. A very low slope means a hi-tech roof, and a high slope a low-tech roof.

To comprehend this theory, allow us to start with one of the more low-tech roofing systems: a thatch roof. Thatch roofs in the majority of countries will have a slope of 45 degrees or so. This is mainly because they are not very watertight. However, they're rather thick, regularly 400mm (16") or so. So the high slope forces the water to run off before it permeates through the thickness of the thatch, a low-tech solution.

Alternatively, a state of the art system such as low-slope "kliplock" corrugated metal sheets can be installed at slopes of 1 degree or less, as it is completely watertight.

Aside from being water tight, a roof must perform additional functions: it must support snow, must be aesthetically pleasing, must have a permanent abrasion-resistant finish, must not absorb heat in hot climates, and must retain heat in cold climates.

Thatch Roofs: are among the earliest roofing systems created by man, and are even now utilized in millions of buildings worldwide. Consisting of dried plant stems, a thatch roof will typically employ a slope of 45 degrees and thickness of 400mm (16"). This thickness is made up of many layers of individual plant fibres. When water falls on a thatch roof, it will trickle from layer to layer as gravity brings it downwards. So the thickness essentially creates sufficient layers for the water drops to shift horizontally outside the structure before they fall into a room. The steep slope will serve to accelerate the speed of the drops, so that they can swiftly get out of the construction before falling inside. So this style of roof is quite different from other roofs, as it doesn't have a waterproof skin.

Slate or Stone Roofs: stone isn't the ideal material for roofs, since it is heavy. Slate is a naturally occurring kind of stone that splits into thin layers if you strike it using a chisel in just the proper way. This creates thin, waterproof tiles which can be overlapped to form a roof. Since the stone tiles aren't exactly the exact same size and thickness, this is not a system which is highly waterproof. Therefore it must have a good slope, of say 20 to 30 degrees, to make the water to run off the roof and not trickle through the cracks.

Wood Shingle Roofs: wooden shingles are lightweight and very easily changeable, and were employed widely in many parts of the world.

Metal Roofing Systems: metal roofing systems are immensely popular in present day constructions. They are chosen in almost every industrial and airport terminal building and may also be used in domestic and educational buildings. They make for an particularly light, robust, economical, and waterproof roof, and are available in a very wide range of varieties. Frequently used metals are mild steel, aluminum, and stainless steel. Steel roofing sheets must be protected from corrosion, and are usually galvanized or covered with other protective layers. The sheets are somewhat thin, approximately 0.5mm in the case of steel, and 1mm in aluminum. They therefore will need insulation and various other layers to be integrated into the roof
