A roofing is part of any building envelope. It is the covering on the uppermost part of a building or shelter which provides protection from family pets and weather, rain or snow notably, but heat also, wind and sunlight. The word denotes the framing or composition which supports that covering also.[1]The characteristics of your roof are based mostly upon the goal of the building it addresses, the available roofing materials and the neighborhood traditions of development and wider concepts of architectural design and practice and may also be governed by local or national legislation. In most countries a roof protects against rain primarily. A verandah might be roofed with material that protects against sun rays but admits the other elements. The roof of a garden conservatory protects plants from cold, wind, and rain, but admits light.

In many elements of the global world ceramic tiles have been the predominant roofing material for years and years, if not millennia. Other roof materials include asphalt, coal tar pitch, EPDM silicone, Hypalon, reboundable foam, PVC, slate, Teflon textile, TPO, and hardwood shakes and shingles.
The construction of a roof is determined by its approach to support and the way the underneath space is bridged and set up roof is pitched. The pitch is the angle at which the roof increases from its most affordable to highest point. Most US domestic architecture, except in very dry areas, has roofs that are sloped, or pitched. Although modern engineering elements such as drainpipes might take away the dependence on pitch, roofs are pitched for reasons of traditions and aesthetics. So the pitch is partly dependent upon stylistic factors, and partially regarding practicalities.
Some types of roof covering, for example thatch, need a steep pitch in order to be durable and waterproof. 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 areas where there is little rainwater, an almost toned roof with a slight run-off provides enough protection against an occasional downpour. Drainpipes remove the need for a sloping roof also.
Somebody who specializes in roof top construction is named a roofer.The durability of your roof is a matter of concern because the roofing is often the least accessible part of any building for purposes of repair and renewal, while its devastation or destruction can have serious results.
Because the purpose of a roof covering is to protect people and their belongings from climatic elements, the insulating properties of the roof structure are a thought in its framework and the choice of roofing material.Some roofer materials, those of natural fibrous material especially, such as thatch, have excellent insulating properties. For all those that not, extra insulation is installed under the exterior covering often. In developed countries, the majority of dwellings have a ceiling installed under the structural members of the roof. The goal of a ceiling is to insulate against warmth and cold, noise, dirt and grime and frequently from the lice and droppings 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 roof surface, it can reduce heating caused by sunlight.Types of insulation are thought or plastic sheeting, with a reflective surface sometimes, installed below the tiles or other material immediately; 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 progressively, 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 covered and ventilated roof covering can suffer from problems like the formation of ice dams surrounding the overhanging eaves in winter, causing drinking water from melted snow on higher elements of the roof structure to penetrate the roofing material. Ice dams arise when heating escapes through the uppermost area of the roof, and the snow at those points melts, refreezing as it drips along the shingles, and collecting by means of ice at the lower points. This may result in structural harm from stress, like the damage of drainage and gutter systems.
