A rooftop is part of an building envelope. It is the covering on the uppermost part of any building or shelter which gives protection from pets or animals and weather, rain or snow notably, but heat also, wind and sunlight. The term also denotes the framing or structure which supports that covering.[1]The characteristics of the roof are centered upon the purpose of the building that this includes, the available roofing materials and the local traditions of construction and wider concepts of architectural design and practice and could also be governed by local or nationwide legislation. In most countries a roof protects mostly against rain. A verandah might be roofed with materials that protects against sunlight but admits the other elements. The roof of the garden conservatory protects plants from cold, wind, and rain, but admits light.

In many parts of the global world ceramic tiles have been the predominant roof materials for centuries, if not millennia. Other roof materials include asphalt, coal tar pitch, EPDM rubber, Hypalon, reboundable foam, PVC, slate, Teflon fabric, TPO, and timber shakes and shingles.
The construction of a roof depends upon its approach to support and how the underneath space is bridged and whether or not the rooftop is pitched. The pitch is the perspective of which the roof goes up from its least expensive to highest point. Most US domestic structures, except in very dried regions, 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 looks and tradition. So the pitch is partly dependent after stylistic factors, and partially regarding practicalities.
Some types of roof covering, for example thatch, require a steep pitch in order to be waterproof and durable. Other styles of roofing, for example pantiles, are unstable on the steeply pitched roof but provide excellent weather protection at a relatively low angle. In locations where there is little rainwater, an almost even roof with hook run-off provides enough protection against an occasional downpour. Drainpipes also take away the need for a sloping roof covering.
A person that specializes in roof top construction is called a roofer.The durability of your roof top is a matter of matter because the roof top is usually the least accessible part of a building for purposes of repair and renewal, while its harm or devastation can have serious effects.
Because the purpose of a rooftop is to safeguard people and their belongings from climatic elements, the insulating properties of your roof structure are a awareness in its framework and the choice of roofing materials.Some roofing materials, especially those of natural fibrous material, such as thatch, have excellent insulating properties. For all those that do not, extra insulation is often installed under the external covering. 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 heat and cold, sound, dirt and grime and frequently from the droppings and lice of wild birds who frequently choose roofs as nesting places.
Cement tiles can be used as insulation. When installed departing a space between your tiles and the roof surface, it can reduce warming caused by sunlight.Forms of insulation are sensed or cheap sheeting, sometimes with a reflective surface, installed directly below the tiles or other materials; 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 have become ever more popular, and sometimes are mandated by local codes. Cool roofs are defined as roofs with both high reflectivity and high thermal emittance.
Poorly protected and ventilated roofer can have problems with problems like the formation of ice dams round the overhanging eaves in winter, causing drinking water from melted snow on higher elements of the roof top to penetrate the roofing materials. Ice dams occur when temperature escapes through the uppermost area of the roof, and the snow at those things melts, refreezing as it drips along the shingles, and collecting by means of ice at the low points. This can lead to structural damage from stress, like the devastation of drainage and gutter systems.
