A roof is part of any building envelope. It's the covering on the uppermost part of any building or shelter which provides protection from pets and weather, rain or snow notably, but also heat, wind and sunlight. The word also denotes the framing or structure which supports that covering.[1]The characteristics of your roof are dependent upon the purpose of the building which it addresses, the available roofing materials and the neighborhood traditions of construction and wider concepts of architectural design and practice and may also be governed by local or countrywide legislation. In most countries a roof protects against rain primarily. A verandah may be roofed with material that protects against sunlight but admits the other elements. The roof of any garden conservatory protects plants from cold, wind, and rain, but admits light.

In many parts of the global world ceramic tiles have been the predominant roof materials for centuries, if not millennia. Other roof materials include asphalt, coal tar pitch, EPDM silicone, Hypalon, polyurethane foam, PVC, slate, Teflon cloth, TPO, and lumber shakes and shingles.
The construction of an roof is determined by its approach to support and the way the underneath space is bridged and whether or not the roof top is pitched. The pitch is the viewpoint at which the roof rises from its minimum to highest point. Most US home architecture, except in very dried areas, has roofs that are sloped, or pitched. Although modern building elements such as drainpipes might take away the need for pitch, roofs are pitched for reasons of appearance and tradition. So the pitch is dependent after stylistic factors partly, and partially to do with practicalities.
Some types of roofer, for example thatch, require a steep pitch in order to be durable and waterproof. Other styles of roofing, for example pantiles, are unstable over a steeply pitched roof but provide excellent weather protection at a comparatively low angle. In parts where there is little rainfall, an almost flat roof with hook run-off provides adequate protection against an intermittent downpour. Drainpipes take away the need for a sloping roof structure also.
A person that specializes in roof covering construction is called a roofer.The durability of your roof structure is a matter of concern because the roof is usually the least accessible part of an building for purposes of repair and renewal, while its destruction or destruction can have serious effects.
Because the purpose of a roof top is to safeguard people and their property from climatic elements, the insulating properties of any roof covering are a awareness in its framework and the decision of roofing materials.Some roof covering materials, those of natural fibrous material specifically, such as thatch, have excellent insulating properties. For those that not, extra insulation is installed under the external covering often. In developed countries, nearly all dwellings have a ceiling installed under the structural members of the roof. The purpose of a roof is to insulate against temperature and cold, noise, mud and often from the lice and droppings of parrots who frequently choose roofs as nesting places.
Cement tiles can be used as insulation. When installed giving a space between the tiles and the roof surface, it can reduce heating up caused by sunlight.Forms of insulation are vinyl or experienced sheeting, with a reflective surface sometimes, installed below the tiles or other materials directly; synthetic foam batting laid above the ceiling and recycled paper products and other such materials that can be inserted or sprayed into roof cavities. So called Cool roofs have become popular ever more, and sometimes are mandated by local codes. Cool roofs are thought as roofs with both high reflectivity and high thermal emittance.
Poorly insulated and ventilated roof can have problems with problems like the formation of ice dams around the overhanging eaves in cold weather, causing water from melted snow on upper elements of the roof top to penetrate the roofing materials. Ice dams occur when high temperature escapes through the uppermost part of the roof, and the snow at those factors melts, refreezing as it drips along the shingles, and collecting by means of ice at the low points. This may bring about structural destruction from stress, like the destruction of drainage and gutter systems.
