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

In lots of parts of the global world ceramic tiles have been the predominant roofing materials for centuries, if not millennia. Other roofer materials include asphalt, coal tar pitch, EPDM plastic, Hypalon, polyurethane foam, PVC, slate, Teflon fabric, TPO, and solid wood shingles and shakes.
The construction of a roof is determined by its approach to support and how the underneath space is bridged and set up rooftop is pitched. The pitch is the angle at which the roof rises from its most affordable to highest point. Most US home structures, except in very dried out locations, has roofs that are sloped, or pitched. Although modern structure elements such as drainpipes may remove the dependence on pitch, roofs are pitched for reasons of custom and aesthetics. So the pitch is dependent after stylistic factors partly, and partially regarding practicalities.
Some types of roofing, for example thatch, need a steep pitch to become durable and waterproof. 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 areas where there is little rainwater, an almost chiseled roof with a slight run-off provides enough protection against an intermittent downpour. Drainpipes remove the need for a sloping roof also.
A person that specializes in rooftop construction is named a roofer.The durability of the roof covering is a matter of concern because the rooftop is often the least accessible part of a building for purposes of repair and renewal, while its destruction or harm can have serious effects.
Because the reason for a roof covering is to protect people and their possessions from climatic elements, the insulating properties of an roof are a thought in its composition and the decision of roofing material.Some roofing materials, those of natural fibrous material specifically, such as thatch, have excellent insulating properties. For those that do not, extra insulation is installed under the exterior covering often. In developed countries, nearly all dwellings have a ceiling installed under the structural members of the roof. The goal of a roof is to insulate against warmth and cold, noises, dirt and grime and frequently from the droppings and lice of parrots who frequently choose roofs as nesting places.
Cement tiles can be used as insulation. When installed departing a space between the tiles and the roof structure surface, it can reduce home heating caused by sunlight.Types of insulation are clear plastic or experienced sheeting, sometimes with a reflective surface, installed below the tiles or other material immediately; 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 defined as roofs with both high reflectivity and high thermal emittance.
Poorly insulated and ventilated roofer can suffer from problems such as the formation of ice dams throughout the overhanging eaves in winter, causing normal water from melted snow on upper elements of the roofing to penetrate the roofing material. Ice dams appear when heating escapes through the uppermost area of the roof, and the snow at those tips melts, refreezing as it drips across the shingles, and collecting by means of ice at the low points. This can cause structural harm from stress, like the destruction of gutter and drainage systems.
