A rooftop is part of a 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 also heat, sunlight and wind. The term also denotes the framing or structure which supports that covering.[1]The characteristics of your roof are centered upon the purpose of the building that it includes, the available roof covering materials and the neighborhood 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 may be roofed with material 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 earth ceramic tiles have been the predominant roofer material for centuries, if not millennia. Other roof materials include asphalt, coal tar pitch, EPDM plastic, Hypalon, polyurethane foam, PVC, slate, Teflon cloth, TPO, and real wood shakes and shingles.
The construction of the roof depends upon its approach to support and how the underneath space is bridged and set up rooftop is pitched. The pitch is the angle of which the roof goes up from its most affordable to highest point. Most US local architecture, except in very dried parts, has roofs that are sloped, or pitched. Although modern building elements such as drainpipes may remove the dependence on pitch, roofs are pitched for reasons of looks and traditions. So the pitch is dependent upon stylistic factors partly, and partially regarding practicalities.
Some types of roof, 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 relatively low angle. In parts where there is little rainfall, an almost chiseled roof with a slight run-off provides enough protection against an intermittent downpour. Drainpipes also take away the dependence on a sloping rooftop.
Somebody who specializes in roof covering construction is named a roofer.The durability of the roof is a matter of matter because the roof is often the least accessible part of your building for purposes of repair and renewal, while its damage or harm can have serious results.
Because the reason for a roof structure is to protect people and their property from climatic elements, the insulating properties of any rooftop are a awareness in its structure and the decision of roofing material.Some roof covering materials, those of natural fibrous material specifically, such as thatch, have excellent insulating properties. For those that do not, extra insulation is often installed under the exterior coating. In developed countries, the majority of dwellings have a ceiling installed under the structural members of the roof. The purpose of a ceiling is to insulate against warmth and cold, noise, mud and often from the droppings and lice of parrots who frequently choose roofs as nesting places.
Cement tiles can be used as insulation. When installed departing a space between the tiles and the roof top surface, it can reduce warming caused by sunlight.Types of insulation are plastic or felt sheeting, sometimes with a reflective surface, installed below the tiles or other material 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 increasingly 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 insulated and ventilated roof covering can have problems with problems like the formation of glaciers dams throughout the overhanging eaves in cold weather, causing drinking water from melted snow on top elements of the roof covering to permeate the roofing material. Ice dams appear when temperature escapes through the uppermost area of the roof, and the snow at those tips melts, refreezing as it drips along the shingles, and collecting by means of ice at the low points. This may lead to structural destruction from stress, including the devastation of gutter and drainage systems.
