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

In many parts of the earth ceramic tiles have been the predominant roof covering material for years and years, if not millennia. Other roofing materials include asphalt, coal tar pitch, EPDM silicone, Hypalon, polyurethane foam, PVC, slate, Teflon textile, TPO, and timber shakes and shingles.
The construction of any roof is determined by its method of support and how the underneath space is bridged and whether or not the roof is pitched. The pitch is the viewpoint of which the roof rises from its least expensive to highest point. Most US domestic architecture, except in very dry locations, has roofs that are sloped, or pitched. Although modern building elements such as drainpipes may remove the need for pitch, roofs are pitched for reasons of appearance and tradition. So the pitch is dependent upon stylistic factors partly, also to do with practicalities partially.
Some types of roofing, for example thatch, need a steep pitch in order to be waterproof and durable. Other styles of roofing, for example pantiles, are unstable over a steeply pitched roof but provide excellent weather protection at a comparatively low angle. In areas where there is little rain, an almost smooth roof with a slight run-off provides sufficient protection against an occasional downpour. Drainpipes also take away the dependence on a sloping roofing.
A person that specializes in rooftop construction is called a roofer.The durability of the roof structure is a subject of concern because the roof top is usually the least accessible part of a building for purposes of repair and renewal, while its destruction or damage can have serious effects.
Because the purpose of a roof top is to protect people and their possessions from climatic elements, the insulating properties of your roof top are a thought in its composition and the decision of roofing material.Some roof materials, those of natural fibrous materials especially, such as thatch, have excellent insulating properties. For those that do not, extra insulation is often installed under the exterior level. 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 heating and cold, noises, dirt and grime and frequently from the lice and droppings of birds who frequently choose roofs as nesting places.
Concrete tiles can be used as insulation. When installed giving a space between your tiles and the roof top surface, it can reduce heating system caused by sunlight.Forms of insulation are plastic material or experienced sheeting, sometimes with a reflective surface, installed below the tiles or other materials immediately; 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 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 round the overhanging eaves in winter, causing drinking water from melted snow on higher elements of the rooftop to penetrate the roofing material. Ice dams occur when warmth escapes through the uppermost area of the roof, and the snow at those items melts, refreezing as it drips across the shingles, and collecting by means of ice at the lower points. This may cause structural damage from stress, including the damage of drainage and gutter systems.
