A roofing is part of your building envelope. It's the covering on the uppermost part of an building or shelter which provides protection from family pets and weather, rain or snow notably, but heat also, 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 goal of the building which it protects, the available roofing materials and the local traditions of development and wider ideas 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 might be roofed with material that protects against sun light 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 covering material for centuries, if not millennia. Other roof covering materials include asphalt, coal tar pitch, EPDM silicone, Hypalon, polyurethane foam, PVC, slate, Teflon cloth, TPO, and wood shakes and shingles.
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 angle at which the roof rises from its least expensive to highest point. Most US local structures, except in very dried up parts, has roofs that are sloped, or pitched. Although modern structure elements such as drainpipes may remove the need for pitch, roofs are pitched for reasons of looks and traditions. So the pitch is dependent after stylistic factors partly, and partially regarding practicalities.
Some types of roof, for example thatch, need 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 regions where there is little rain, an almost toned roof with hook run-off provides adequate protection against an intermittent downpour. Drainpipes remove the dependence on a sloping roofing also.
Somebody who specializes in roof structure construction is named a roofer.The durability of an roof covering is a subject of matter because the roof top is usually the least accessible part of your building for purposes of repair and renewal, while its destruction or devastation can have serious effects.
Because the purpose of a roofing is to safeguard people and their belongings from climatic elements, the insulating properties of your roof structure are a thought in its composition and the decision of roofing material.Some roofing materials, especially those of natural fibrous materials, such as thatch, have excellent insulating properties. For all those that not, extra insulation is installed under the outside part often. In developed countries, nearly all dwellings have a ceiling installed under the structural members of the roof. The goal of a ceiling is to insulate against temperature and cold, noise, mud 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 going out of a space between the tiles and the roof surface, it can reduce heating up caused by the sun.Forms of insulation are clear plastic or sensed sheeting, sometimes with a reflective surface, 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 have become more and more popular, and in some 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 can suffer from problems including the formation of glaciers dams surrounding the overhanging eaves in cold weather, causing drinking water from melted snow on top parts of the rooftop to penetrate the roofing materials. Ice dams arise when high temperature escapes through the uppermost part of the roof, and the snow at those tips melts, refreezing as it drips across the shingles, and collecting in the form of ice at the lower points. This can bring about structural harm from stress, like the destruction of drainage and gutter systems.
