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

In lots of parts of the global world ceramic tiles have been the predominant roof covering material for centuries, if not millennia. Other roof covering materials include asphalt, coal tar pitch, EPDM silicone, Hypalon, reboundable foam, PVC, slate, Teflon fabric, TPO, and wood shingles and shakes.
The construction of the roof is determined by its approach to support and the way the underneath space is bridged and whether or not the roof covering is pitched. The pitch is the perspective at which the roof rises from its most affordable to highest point. Most US domestic architecture, except in very dried out parts, has roofs that are sloped, or pitched. Although modern construction elements such as drainpipes may remove the dependence on pitch, roofs are pitched for reasons of tradition and appearance. So the pitch is dependent after stylistic factors partly, also to do with practicalities partly.
Some types of roof covering, for example thatch, require a steep pitch in order to be waterproof and durable. Other types of roofing, for example pantiles, are unstable over a steeply pitched roof but provide excellent weather protection at a relatively low angle. In locations where there is little rainfall, an almost even roof with a slight run-off provides enough protection against an intermittent downpour. Drainpipes take away the dependence on a sloping rooftop also.
Somebody who specializes in roofing construction is called a roofer.The durability of a roof structure is a matter of concern because the rooftop is often the least accessible part of an building for purposes of repair and renewal, while its damage or damage can have serious results.
Because the reason for a roof structure is to safeguard people and their belongings from climatic elements, the insulating properties of any roofing are a concern in its structure and the decision of roofing material.Some roof covering materials, particularly those of natural fibrous material, such as thatch, have excellent insulating properties. For all those that not, extra insulation is installed under the outer level 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, sound, dirt and frequently from the droppings and lice of wild birds who frequently choose roofs as nesting places.
Cement tiles can be used as insulation. When installed leaving a space between your tiles and the roof surface, it can reduce heating up caused by sunlight.Forms of insulation are sensed or clear plastic sheeting, with a reflective surface sometimes, installed below the tiles or other material straight; 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 have become popular significantly, 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 covering can have problems with problems including the formation of glaciers dams across the overhanging eaves in cold weather, causing drinking water from melted snow on top elements of the rooftop to permeate the roofing materials. Ice dams happen when heating escapes through the uppermost area of the roof, and the snow at those details melts, refreezing as it drips along the shingles, and collecting in the form of ice at the lower points. This can result in structural damage from stress, including the devastation of gutter and drainage systems.
