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

In lots of parts of the world ceramic tiles have been the predominant roofing materials for centuries, if not millennia. Other roofing materials include asphalt, coal tar pitch, EPDM plastic, Hypalon, reboundable foam, PVC, slate, Teflon cloth, TPO, and hardwood shakes and shingles.
The construction of an roof depends upon its method of support and the way the underneath space is bridged and set up roof covering is pitched. The pitch is the angle at which the roof goes up from its least expensive to highest point. Most US local architecture, except in very dry locations, has roofs that are sloped, or pitched. Although modern construction elements such as drainpipes might remove the dependence on pitch, roofs are pitched for reasons of appearance and tradition. So the pitch is dependent after stylistic factors partly, and to do with practicalities partially.
Some types of roof, for example thatch, require a steep pitch to become waterproof and durable. Other types of roofing, for example pantiles, are unstable on a steeply pitched roof but provide excellent weather protection at a relatively low angle. In parts where there is little rainwater, an almost chiseled roof with a slight run-off provides adequate protection against an occasional downpour. Drainpipes remove the need for a sloping roofing also.
A person that specializes in roofing construction is named a roofer.The durability of an roof is a matter of concern because the roofing is usually the least accessible part of a building for purposes of repair and renewal, while its damage or destruction can have serious effects.
Because the purpose of a rooftop is to safeguard people and their property from climatic elements, the insulating properties of a roof structure are a thought in its composition and the decision of roofing materials.Some roof materials, those of natural fibrous materials particularly, such as thatch, have excellent insulating properties. For those that do not, extra insulation is often installed under the outside level. In developed countries, nearly all 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 grime and often from the droppings and lice of parrots who frequently choose roofs as nesting places.
Cement tiles can be used as insulation. When installed leaving a space between the tiles and the roofing surface, it can reduce heat caused by sunlight.Forms of insulation are clear plastic or sensed sheeting, sometimes with a reflective surface, installed directly below the tiles or other material; 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 are becoming popular significantly, and in some full cases are mandated by local codes. Cool roofs are defined as roofs with both high reflectivity and high thermal emittance.
Poorly insulated and ventilated roof covering can have problems with problems like the formation of snow dams about the overhanging eaves in cold weather, causing normal water from melted snow on top elements of the roof structure to permeate the roofing materials. Ice dams arise when heat escapes through the uppermost part of the roof, and the snow at those true tips melts, refreezing as it drips along the shingles, and collecting by means of ice at the low points. This can result in structural destruction from stress, like the devastation of drainage and gutter systems.
