A roof top is part of a building envelope. It is the covering on the uppermost part of any building or shelter which provides protection from pets or animals and weather, rain or snow notably, but also heat, sunlight and wind. The word also denotes the framing or structure which supports that covering.[1]The characteristics of a roof are based mostly upon the purpose of the building that it addresses, the available roof covering materials and the local traditions of building and wider ideas 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 your garden conservatory protects plants from cold, wind, and rain, but admits light.

In lots of parts of the world ceramic tiles have been the predominant roofing material for centuries, if not millennia. Other roofing materials include asphalt, coal tar pitch, EPDM plastic, Hypalon, reboundable foam, PVC, slate, Teflon fabric, TPO, and timber shakes and shingles.
The construction of any roof is determined by its approach to support and how the underneath space is bridged and whether or not the roof covering is pitched. The pitch is the position of which the roof goes up 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 structure elements such as drainpipes may remove the dependence on pitch, roofs are pitched for reasons of custom and appearance. So the pitch is dependent after stylistic factors partly, also to do with practicalities partly.
Some types of roof, for example thatch, need a steep pitch to become durable and waterproof. Other types of roofing, for example pantiles, are unstable on a steeply pitched roof but provide excellent weather protection at a relatively low angle. In areas where there is little rainfall, an almost flat roof with a slight run-off provides satisfactory protection against an intermittent downpour. Drainpipes also take away the dependence on a sloping roofing.
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 covering is often the least accessible part of any building for purposes of repair and renewal, while its damage or destruction can have serious results.
Because the purpose of a roof top is to safeguard people and their property from climatic elements, the insulating properties of a roof are a consideration in its composition and the choice of roofing materials.Some roofer materials, especially those of natural fibrous materials, such as thatch, have excellent insulating properties. For all those that not, extra insulation is often installed under the outer coating. In developed countries, nearly all dwellings have a ceiling installed under the structural members of the roof. The purpose of a ceiling is to insulate against heating and cold, sound, mud and often from the lice and droppings of wild birds who frequently choose roofs as nesting places.
Concrete tiles can be used as insulation. When installed departing a space between the tiles and the roof top surface, it can reduce heat caused by sunlight.Types of insulation are felt or plastic sheeting, sometimes with a reflective surface, 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 progressively 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 protected and ventilated roof can suffer from problems including the formation of glaciers dams around the overhanging eaves in winter, causing drinking water from melted snow on upper elements of the roofing to penetrate the roofing material. Ice dams appear when temperature escapes through the uppermost area of the roof, and the snow at those true things melts, refreezing as it drips across the shingles, and collecting in the form of ice at the low points. This can lead to structural damage from stress, like the destruction of gutter and drainage systems.
