A roof structure is part of a building envelope. It's the covering on the uppermost part of your building or shelter which gives 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 a roof are reliant upon the purpose of the building so it addresses, the available roofing materials and the local traditions of engineering and wider ideas of architectural design and practice and may also be governed by local or countrywide legislation. In most countries a roof protects mostly against rain. A verandah may be roofed with material that protects against sunlight 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 globe ceramic tiles have been the predominant roofing material for years and years, if not millennia. Other roof covering materials include asphalt, coal tar pitch, EPDM rubber, Hypalon, reboundable foam, PVC, slate, Teflon cloth, TPO, and wood shingles and shakes.
The construction of a roof is determined by its method of support and how the underneath space is bridged and set up roof is pitched. The pitch is the viewpoint at which the roof goes up from its minimum to highest point. Most US local architecture, except in very dried up locations, has roofs that are sloped, or pitched. Although modern structure elements such as drainpipes may take away the dependence on pitch, roofs are pitched for reasons of looks and tradition. So the pitch is dependent upon stylistic factors partly, also to do with practicalities partly.
Some types of roof covering, for example thatch, require a steep pitch to become durable and waterproof. Other types of roofing, for example pantiles, are unstable on a steeply pitched roof but provide excellent weather protection at a comparatively low angle. In parts where there is little rainwater, an almost level roof with hook run-off provides sufficient protection against an occasional downpour. Drainpipes remove the need for a sloping roof also.
Somebody who specializes in roof construction is called a roofer.The durability of a roof is a subject of concern because the roof top is often the least accessible part of your building for purposes of repair and renewal, while its destruction or destruction can have serious effects.
Because the purpose of a roof is to protect people and their possessions from climatic elements, the insulating properties of a roof structure are a consideration in its structure and the choice of roofing materials.Some roofer materials, those of natural fibrous material specifically, such as thatch, have excellent insulating properties. For all those that do not, extra insulation is often installed under the outside covering. 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 heating and cold, noises, dirt and often from the lice and droppings of birds who frequently choose roofs as nesting places.
Concrete tiles can be utilized as insulation. When installed leaving a space between the tiles and the roof covering surface, it can reduce heating system caused by the sun.Forms of insulation are experienced or cheap sheeting, with a reflective surface sometimes, installed straight 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 popular more and more, and in some full cases 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 suffer from problems including the formation of ice dams throughout the overhanging eaves in cold weather, causing normal water from melted snow on higher parts of the roof to permeate the roofing material. Ice dams appear when temperature escapes through the uppermost area of the roof, and the snow at those true points melts, refreezing as it drips over the shingles, and collecting by means of ice at the lower points. This can cause structural destruction from stress, including the devastation of drainage and gutter systems.
