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

In lots of parts of the planet ceramic tiles have been the predominant roof covering material for centuries, if not millennia. Other roof covering materials include asphalt, coal tar pitch, EPDM rubber, Hypalon, reboundable foam, PVC, slate, Teflon fabric, TPO, and timber shakes and shingles.
The construction of an roof is determined by its method of support and how the underneath space is bridged and whether or not the roofing is pitched. The pitch is the position of which the roof goes up from its least expensive to highest point. Most US domestic architecture, except in very dried areas, has roofs that are sloped, or pitched. Although modern construction elements such as drainpipes might take away the need for pitch, roofs are pitched for reasons of appearance and traditions. So the pitch is dependent after stylistic factors partly, and to do with practicalities partially.
Some types of roofer, for example thatch, require a steep pitch to become durable and waterproof. Other styles of roofing, for example pantiles, are unstable on the steeply pitched roof but provide excellent weather protection at a comparatively low angle. In areas where there is little rain, an almost flat roof with a slight run-off provides enough protection against an occasional downpour. Drainpipes also remove the need for a sloping roof top.
A person that specializes in roofing construction is named a roofer.The durability of the roof structure is a matter of concern because the roofing is usually the least accessible part of your building for purposes of repair and renewal, while its destruction or damage can have serious effects.
Because the purpose of a roofing is to safeguard people and their property from climatic elements, the insulating properties of the rooftop are a consideration in its composition and the decision of roofing material.Some roof materials, those of natural fibrous material particularly, such as thatch, have excellent insulating properties. For all those that not, extra insulation is installed under the outer level often. In developed countries, the majority of dwellings have a ceiling installed under the structural members of the roof. The purpose of a ceiling is to insulate against heating and cold, sound, dirt and frequently from the droppings and lice of parrots who frequently choose roofs as nesting places.
Concrete tiles can be used as insulation. When installed giving a space between the tiles and the roof surface, it can reduce warming caused by the sun.Forms of insulation are clear plastic or thought sheeting, with a reflective surface sometimes, installed immediately below the tiles or other material; synthetic foam batting laid above the ceiling and recycled paper products and other such materials that may be inserted or sprayed into roof cavities. So called Cool roofs are becoming increasingly popular, and occasionally are mandated by local codes. Cool roofs are defined as roofs with both high reflectivity and high thermal emittance.
Poorly protected and ventilated roof can have problems with problems including the formation of snow dams across the overhanging eaves in winter, causing water from melted snow on upper elements of the roof structure to penetrate the roofing materials. Ice dams take place when heating escapes through the uppermost area of the roof, and the snow at those points melts, refreezing as it drips over the shingles, and collecting in the form of ice at the low points. This can lead to structural harm from stress, including the devastation of gutter and drainage systems.
