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 animals 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 an roof are dependent upon the goal of the building so it covers, the available roofing materials and the local traditions of building and wider principles of architectural design and practice and may also be governed by local or nationwide legislation. In most countries a roof protects primarily 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 roof material for years and years, if not millennia. Other roof covering materials include asphalt, coal tar pitch, EPDM rubber, Hypalon, polyurethane foam, PVC, slate, Teflon fabric, TPO, and solid wood shingles and shakes.
The construction of any roof depends upon its method of support and how the underneath space is bridged and set up roof is pitched. The pitch is the viewpoint of which the roof rises from its most affordable to highest point. Most US home architecture, except in very dry out locations, has roofs that are sloped, or pitched. Although modern construction elements such as drainpipes might take away the need for pitch, roofs are pitched for reasons of tradition and appearance. So the pitch is partly dependent after stylistic factors, and to do with practicalities partly.
Some types of roofing, for example thatch, need a steep pitch in order to be waterproof and durable. Other styles of roofing, for example pantiles, are unstable on the steeply pitched roof but provide excellent weather protection at a relatively low angle. In parts where there is little rainfall, an almost level roof with a slight run-off provides enough protection against an occasional downpour. Drainpipes take away the dependence on a sloping roof covering also.
Somebody who specializes in roof covering construction is called a roofer.The durability of an roof top is a matter of matter because the roof top is often the least accessible part of a building for purposes of repair and renewal, while its damage or destruction can have serious results.
Because the reason for a roofing is to safeguard people and their property from climatic elements, the insulating properties of an roofing are a concern in its structure and the decision of roofing material.Some roofer materials, particularly those of natural fibrous materials, such as thatch, have excellent insulating properties. For all those that do not, extra insulation is installed under the external covering often. In developed countries, the majority of dwellings have a ceiling installed under the structural members of the roof. The goal of a roof is to insulate against high temperature and cold, noise, dirt and frequently 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 structure surface, it can reduce heating caused by the sun.Types of insulation are plastic or felt sheeting, with a reflective surface sometimes, installed directly 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 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 such as the formation of ice dams about the overhanging eaves in cold weather, causing water from melted snow on upper parts of the roofing to permeate the roofing materials. Ice dams take place when high temperature escapes through the uppermost part of the roof, and the snow at those items melts, refreezing as it drips along the shingles, and collecting by means of ice at the low points. This may cause structural harm from stress, including the devastation of gutter and drainage systems.
