A rooftop is part of your building envelope. It's the covering on the uppermost part of your building or shelter which provides protection from animals and weather, notably rain or snow, but also heat, sunlight and wind. The term also denotes the framing or structure which supports that covering.[1]The characteristics of the roof are based mostly upon the purpose of the building that this addresses, the available roof covering materials and the neighborhood traditions of building 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 protects against sunshine but admits the other elements. The roof of an 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 roof covering material for centuries, if not millennia. Other roofer materials include asphalt, coal tar pitch, EPDM rubber, Hypalon, polyurethane foam, PVC, slate, Teflon cloth, TPO, and wood shingles and shakes.
The construction of an roof depends upon its method of support and how the underneath space is bridged and set up roof covering is pitched. The pitch is the position at which the roof goes up from its minimum to highest point. Most US domestic architecture, except in very dry parts, has roofs that are sloped, or pitched. Although modern development elements such as drainpipes may take away the dependence on pitch, roofs are pitched for reasons of aesthetics and tradition. So the pitch is partly dependent upon stylistic factors, also to do with practicalities partly.
Some types of roof covering, for example thatch, need a steep pitch in order to be durable and waterproof. Other types of roofing, for example pantiles, are unstable on a steeply pitched roof but provide excellent weather protection at a relatively low angle. In regions where there is little rainwater, an almost even roof with a slight run-off provides adequate protection against an intermittent downpour. Drainpipes take away the need for a sloping roof top also.
A person that specializes in rooftop construction is called a roofer.The durability of any roof structure is a matter of matter because the roof structure is often the least accessible part of the 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 property from climatic elements, the insulating properties of any roofing are a account in its composition and the decision of roofing material.Some roof 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 layer often. 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 heat and cold, sound, dirt and grime and frequently from the droppings and lice 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 surface, it can reduce heating up caused by the sun.Forms of insulation are noticed or clear plastic sheeting, sometimes with a reflective surface, installed directly below the tiles or other material; synthetic foam batting laid above the ceiling and recycled paper products and other such materials that may 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 covered and ventilated roof covering can have problems with problems including the formation of snow dams round the overhanging eaves in winter, causing normal water from melted snow on top parts of the rooftop to penetrate the roofing materials. Ice dams take place when temperature escapes through the uppermost area of the roof, and the snow at those true things melts, refreezing as it drips across the shingles, and collecting by means of ice at the lower points. This may lead to structural damage from stress, like the destruction of gutter and drainage systems.
