A rooftop is part of an building envelope. It's the covering on the uppermost part of a building or shelter which gives protection from pets and weather, notably rain or snow, but also heat, sunlight and wind. The word denotes the framing or framework which helps that covering also.[1]The characteristics of any roof are centered upon the goal of the building it addresses, the available roof covering materials and the local traditions of construction and wider ideas of architectural design and practice and could also be governed by local or countrywide legislation. In most countries a roof protects against rain primarily. A verandah might be roofed with materials that defends against sun light but admits the other elements. The roof of any garden conservatory protects plants from cold, wind, and rain, but admits light.

The construction of a roof is determined by its method of support and the way the underneath space is bridged and whether or not the roofing is pitched. The pitch is the viewpoint at which the roof rises from its most affordable to highest point. Most US local architecture, except in very dried up parts, has roofs that are sloped, or pitched. Although modern development elements such as drainpipes might take away the need for pitch, roofs are pitched for reasons of custom and appearance. So the pitch is partly dependent upon stylistic factors, and partially to do with practicalities.
Some types of roof, for example thatch, require a steep pitch in order to be durable and waterproof. 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 parts where there is little rainwater, an almost toned roof with hook run-off provides satisfactory protection against an intermittent downpour. Drainpipes also remove the dependence on a sloping roof structure.
Somebody who specializes in rooftop construction is called a roofer.The durability of the roof structure is a subject of concern because the roof covering is often the least accessible part of a building for purposes of repair and renewal, while its damage or destruction can have serious effects.
Because the purpose of a rooftop is to safeguard people and their property from climatic elements, the insulating properties of the roofing are a factor in its composition and the decision of roofing materials.Some roofer materials, those of natural fibrous materials particularly, such as thatch, have excellent insulating properties. For all those that do not, extra insulation is installed under the outside layer often. In developed countries, nearly all dwellings have a ceiling installed under the structural members of the roof. The purpose of a roof is to insulate against warmth and cold, noise, dirt and grime and frequently from the droppings and lice of birds who frequently choose roofs as nesting places.
Cement tiles can be utilized as insulation. When installed departing a space between your tiles and the roof covering surface, it can reduce warming caused by the sun.Forms of insulation are vinyl or believed sheeting, with a reflective surface sometimes, 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 are becoming popular increasingly, and occasionally are mandated by local codes. Cool roofs are thought as roofs with both high reflectivity and high thermal emittance.
Poorly protected and ventilated roofer can suffer from problems including the formation of snow dams surrounding the overhanging eaves in winter, causing drinking water from melted snow on higher parts of the roof structure to penetrate the roofing materials. Ice dams occur when warmth escapes through the uppermost part of the roof, and the snow at those true factors melts, refreezing as it drips along the shingles, and collecting in the form of ice at the low points. This may lead to structural destruction from stress, like the devastation of drainage and gutter systems.
