A rooftop is part of an building envelope. It's the covering on the uppermost part of an building or shelter which provides protection from family pets and weather, rain or snow notably, but also heat, wind and sunlight. The word denotes the framing or composition which supports that covering also.[1]The characteristics of a roof are reliant upon the purpose of the building which it covers, the available roof materials and the local traditions of engineering and wider concepts of architectural design and practice and could also be governed by local or national legislation. In most countries a roof protects against rain primarily. A verandah might be roofed with material that helps to protect 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 elements of the global world ceramic tiles have been the predominant roofer material for years and years, if not millennia. Other roofer materials include asphalt, coal tar pitch, EPDM plastic, Hypalon, polyurethane foam, PVC, slate, Teflon textile, TPO, and wood shingles and shakes.
The construction of an roof depends upon its approach to support and the way the underneath space is bridged and set up roof top is pitched. The pitch is the viewpoint of which the roof increases from its least expensive to highest point. Most US home architecture, except in very dry parts, has roofs that are sloped, or pitched. Although modern structure elements such as drainpipes might take away the dependence on pitch, roofs are pitched for reasons of custom and aesthetics. So the pitch is dependent after stylistic factors partly, and partially to do with 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 over a steeply pitched roof but provide excellent weather protection at a comparatively low angle. In parts where there is little rain, an almost chiseled roof with hook run-off provides adequate protection against an intermittent downpour. Drainpipes remove the need for a sloping roofing also.
A person that specializes in rooftop construction is called a roofer.The durability of any roofing is a subject of matter because the roof top is usually the least accessible part of an building for purposes of repair and renewal, while its damage or damage can have serious results.
Because the purpose of a roof is to protect people and their belongings from climatic elements, the insulating properties of any roof top are a concern in its composition and the decision of roofing material.Some roofing materials, those of natural fibrous material especially, such as thatch, have excellent insulating properties. For all those that do not, extra insulation is installed under the exterior covering often. 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 warmth and cold, noises, dirt and grime and often from the droppings and lice of wild birds who frequently choose roofs as nesting places.
Cement tiles can be utilized as insulation. When installed departing a space between the tiles and the roofing surface, it can reduce heat caused by sunlight.Types of insulation are sensed or cheap 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 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 defined as roofs with both high reflectivity and high thermal emittance.
Poorly protected and ventilated roof can have problems with problems like the formation of ice dams round the overhanging eaves in winter, causing water from melted snow on higher parts of the roof to permeate the roofing materials. Ice dams occur when temperature escapes through the uppermost area of the roof, and the snow at those true details melts, refreezing as it drips over the shingles, and collecting by means of ice at the lower points. This may bring about structural destruction from stress, like the devastation of gutter and drainage systems.
