A roofer specializes in roof construction, concentrating on the application of materials that water proof and / or weather proof buildings,designed material�as a substrate for the roofing materials to be installed on. The rafters, beams, and trusses are the frame or skeleton for the roof to be built upon. Naturally, a roofer must not be scared of heights and have good balance as well as carpentry skills. In Australia this type of carpenter is called a roof carpenter and in that country a roofer is someone who puts on the roof cladding (tiles, tin, etc.). In the USA a well trained roofer is called a journeyman. In California, if a journeyman wishes and has three consecutive years working in the field, he is eligible to pass a state test for a contractors license- state license.
Roofs made of cut turf (modern ones known as Green roofs, traditional ones as sod roofs) have good insulating properties and are increasingly encouraged as a way of "greening" the Earth. Adobe roofs are roofs of clay, mixed with binding material such as straw or animal hair, and plastered on lathes to form a flat or gently sloped roof, usually in areas of low rainfall.
. Some roofing materials, particularly those of natural fibrous material, such as thatch, have excellent insulating properties. For those that do not, extra insulation is often installed under the outer layer. In developed countries, the majority of dwellings have a ceiling installed under the structural member of the roof. The purpose is to insulate against heat and cold, noise, dirt and often from the droppings and lice of birds who frequently choose roofs as nesting places.
