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

In many parts of the entire world ceramic tiles have been the predominant roof covering material for centuries, if not millennia. Other roof materials include asphalt, coal tar pitch, EPDM rubber, Hypalon, polyurethane foam, PVC, slate, Teflon cloth, TPO, and real wood 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 roof covering is pitched. The pitch is the angle of which the roof increases from its lowest to highest point. Most US home architecture, except in very dry out regions, has roofs that are sloped, or pitched. Although modern development elements such as drainpipes may remove the dependence on pitch, roofs are pitched for reasons of tradition and aesthetics. So the pitch is dependent after stylistic factors partly, and partially regarding practicalities.
Some types of roofer, for example thatch, require a steep pitch to become waterproof and durable. Other styles of roofing, for example pantiles, are unstable over a steeply pitched roof but provide excellent weather protection at a comparatively low angle. In locations where there is little rain, an almost level roof with a slight run-off provides satisfactory protection against an occasional downpour. Drainpipes also take away the need for a sloping roof.
A person that specializes in roofing construction is named a roofer.The durability of any roof top is a subject of concern because the roof is usually the least accessible part of the building for purposes of repair and renewal, while its damage or damage can have serious effects.
Because the purpose of a rooftop is to safeguard people and their belongings from climatic elements, the insulating properties of the roof are a thought in its composition and the decision of roofing materials.Some roof covering materials, those of natural fibrous material specifically, such as thatch, have excellent insulating properties. For all those that not, extra insulation is often installed under the outer level. 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 heat and cold, noise, 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 giving a space between the tiles and the rooftop surface, it can reduce heating up caused by sunlight.Types of insulation are vinyl or felt sheeting, sometimes with a reflective surface, installed directly below the tiles or other materials; 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 progressively 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 covered and ventilated roof covering can have problems with problems including the formation of glaciers dams about the overhanging eaves in cold weather, causing water from melted snow on higher elements of the roof structure to penetrate the roofing material. Ice dams occur when heat escapes through the uppermost area of the roof, and the snow at those true items melts, refreezing as it drips over the shingles, and collecting by means of ice at the lower points. This may bring about structural damage from stress, like the destruction of drainage and gutter systems.
