A roof covering is part of any building envelope. It is the covering on the uppermost part of your building or shelter which gives protection from family pets and weather, notably rain or snow, but also heat, sunlight and wind. The word denotes the framing or framework which supports that covering also.[1]The characteristics of any roof are centered upon the purpose of the building which it includes, the available roof materials and the neighborhood traditions of development and wider principles 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 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 entire world ceramic tiles have been the predominant roof covering materials for years and years, if not millennia. Other roofer materials include asphalt, coal tar pitch, EPDM rubber, Hypalon, reboundable foam, PVC, slate, Teflon textile, TPO, and timber shakes and shingles.
The construction of a roof depends upon its method of support and the way the underneath space is bridged and whether or not the roof covering is pitched. The pitch is the angle of which the roof rises from its most affordable to highest point. Most US domestic structures, except in very dried locations, has roofs that are sloped, or pitched. Although modern engineering elements such as drainpipes might remove the need for pitch, roofs are pitched for reasons of aesthetics and tradition. So the pitch is dependent after stylistic factors partly, 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 types of roofing, for example pantiles, are unstable on the steeply pitched roof but provide excellent weather protection at a comparatively low angle. In parts where there is little rain, an almost smooth roof with a slight run-off provides satisfactory protection against an occasional downpour. Drainpipes remove the dependence on a sloping roof also.
A person that specializes in roof top construction is named a roofer.The durability of an roof structure is a subject of concern because the roof top is usually the least accessible part of your building for purposes of repair and renewal, while its damage or destruction can have serious results.
Because the reason for a roof top is to safeguard people and their property from climatic elements, the insulating properties of a roof structure are a awareness in its framework and the choice of roofing material.Some roof covering materials, those of natural fibrous materials particularly, such as thatch, have excellent insulating properties. For those that not, extra insulation is often installed under the exterior coating. 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 heat and cold, noises, mud and often from the droppings and lice of wild birds who frequently choose roofs as nesting places.
Cement tiles can be utilized as insulation. When installed going out of a space between the tiles and the roof surface, it can reduce warming caused by sunlight.Types of insulation are felt or plastic sheeting, with a reflective surface sometimes, installed immediately 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 ever 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 including the formation of snow dams surrounding the overhanging eaves in cold weather, causing normal water from melted snow on higher parts of the roof to permeate the roofing materials. Ice dams happen when warmth escapes through the uppermost area of the roof, and the snow at those points melts, refreezing as it drips over the shingles, and collecting by means of ice at the lower points. This can bring about structural damage from stress, including the destruction of gutter and drainage systems.
