A roof covering is part of a building envelope. It is the covering on the uppermost part of a building or shelter which provides protection from pets and weather, notably rain or snow, but also heat, wind and sunlight. The word denotes the framing or composition which helps that covering also.[1]The characteristics of an roof are centered upon the purpose of the building that it addresses, the available roofing materials and the neighborhood traditions of structure and wider principles of architectural design and practice and could also be governed by local or countrywide 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 an garden conservatory protects plants from cold, wind, and rain, but admits light.

In lots of elements of the global world ceramic tiles have been the predominant roof materials for centuries, if not millennia. Other roofer materials include asphalt, coal tar pitch, EPDM silicone, Hypalon, reboundable foam, PVC, slate, Teflon cloth, TPO, and lumber shakes and shingles.
The construction of any roof is determined by its approach to support and the way the underneath space is bridged and whether or not the roof is pitched. The pitch is the angle of which the roof increases from its least expensive to highest point. Most US local architecture, except in very dry out parts, 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 appearance and custom. So the pitch is dependent after stylistic factors partly, and to do with practicalities partly.
Some types of roof, for example thatch, require a steep pitch to become waterproof and durable. Other types 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 rainfall, an almost even roof with hook run-off provides enough protection against an occasional downpour. Drainpipes also take away the dependence on a sloping roof structure.
A person that specializes in rooftop construction is called a roofer.The durability of your rooftop is a subject of matter because the roofing is usually the least accessible part of any building for purposes of repair and renewal, while its damage or damage can have serious effects.
Because the reason for a roof top is to protect people and their belongings from climatic elements, the insulating properties of your roof structure are a factor in its composition and the choice of roofing materials.Some roof covering materials, those of natural fibrous materials especially, such as thatch, have excellent insulating properties. For all those that do not, extra insulation is often installed under the exterior part. 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 heating and cold, sound, dirt and frequently from the lice and droppings of wild birds who frequently choose roofs as nesting places.
Concrete tiles can be utilized as insulation. When installed giving a space between the tiles and the roof covering surface, it can reduce home heating caused by sunlight.Forms of insulation are plastic material or experienced 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 progressively, and in some cases are mandated by local codes. Cool roofs are defined as roofs with both high reflectivity and high thermal emittance.
Poorly covered and ventilated roofing can suffer from problems like the formation of glaciers dams about the overhanging eaves in cold weather, causing drinking water from melted snow on top parts of the rooftop to penetrate the roofing material. Ice dams arise when heating escapes through the uppermost part of the roof, and the snow at those details melts, refreezing as it drips along the shingles, and collecting by means of ice at the lower points. This can bring about structural harm from stress, like the damage of gutter and drainage systems.
