A rooftop is part of the building envelope. It's the covering on the uppermost part of a building or shelter which provides protection from family pets and weather, rain or snow notably, but also heat, wind and sunlight. The term also denotes the framing or structure which supports that covering.[1]The characteristics of an roof are dependent upon the goal of the building it covers, the available roofing materials and the neighborhood traditions of structure and wider ideas of architectural design and practice and may also be governed by local or national legislation. In most countries a roof protects generally against rain. A verandah might be roofed with material that helps to protect against sun rays but admits the other elements. The roof of any garden conservatory protects plants from cold, wind, and rain, but admits light.

In lots of elements of the global world ceramic tiles have been the predominant roofer materials for years and years, if not millennia. Other roof materials include asphalt, coal tar pitch, EPDM rubber, Hypalon, reboundable foam, PVC, slate, Teflon cloth, TPO, and hardwood shingles and shakes.
The construction of your roof is determined by its method of support and how the underneath space is bridged and set up roof is pitched. The pitch is the position at which the roof goes up from its least expensive to highest point. Most US home structures, except in very dry locations, has roofs that are sloped, or pitched. Although modern engineering elements such as drainpipes might take away the need for pitch, roofs are pitched for reasons of tradition and appearance. So the pitch is partly dependent upon stylistic factors, also to do with practicalities partly.
Some types of roofing, for example thatch, require a steep pitch in order to be waterproof and durable. Other types of roofing, for example pantiles, are unstable over a steeply pitched roof but provide excellent weather protection at a comparatively low angle. In parts where there is little rainwater, an almost even roof with hook run-off provides satisfactory protection against an intermittent downpour. Drainpipes take away the need for a sloping rooftop also.
Somebody who specializes in roof structure construction is named a roofer.The durability of any roof top is a matter of concern because the roof is usually the least accessible part of an building for purposes of repair and renewal, while its damage or destruction can have serious effects.
Because the reason for a roof covering is to protect people and their property from climatic elements, the insulating properties of your roof structure are a thought in its structure and the choice of roofing material.Some roofing materials, particularly those of natural fibrous material, such as thatch, have excellent insulating properties. For all those that not, extra insulation is often installed under the exterior level. In developed countries, the majority of dwellings have a ceiling installed under the structural members of the roof. The purpose of a roof is to insulate against warmth and cold, noises, 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 giving a space between the tiles and the roof surface, it can reduce heating up caused by the sun.Forms of insulation are sensed or plastic sheeting, sometimes with a reflective surface, installed straight below the tiles or other material; 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 significantly, 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 can have problems with problems such as the formation of snow dams surrounding the overhanging eaves in cold weather, causing normal water from melted snow on upper parts of the roofing to penetrate the roofing materials. Ice dams appear when warmth escapes through the uppermost area 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 can cause structural harm from stress, like the destruction of gutter and drainage systems.
