A roof top is part of your building envelope. It is the covering on the uppermost part of a building or shelter which provides protection from pets or animals and weather, rain or snow notably, but heat also, sunlight and wind. The term denotes the framing or composition which facilitates that covering also.[1]The characteristics of a roof are reliant upon the purpose of the building so it addresses, the available roof covering materials and the local traditions of engineering and wider concepts of architectural design and practice and may also be governed by local or nationwide legislation. In most countries a roof protects against rain primarily. A verandah may be roofed with material that protects against sunlight but admits the other elements. The roof of an garden conservatory protects plants from cold, wind, and rain, but admits light.

In lots of parts of the global world ceramic tiles have been the predominant roof covering material for centuries, if not millennia. Other roof materials include asphalt, coal tar pitch, EPDM silicone, Hypalon, reboundable foam, PVC, slate, Teflon textile, TPO, and wood shakes and shingles.
The construction of the roof depends upon its method of support and how the underneath space is bridged and set up roof top is pitched. The pitch is the position of which the roof rises from its least expensive to highest point. Most US domestic architecture, except in very dried up parts, has roofs that are sloped, or pitched. Although modern construction elements such as drainpipes might remove the dependence on pitch, roofs are pitched for reasons of aesthetics and custom. So the pitch is partly dependent upon stylistic factors, and 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 on a steeply pitched roof but provide excellent weather protection at a comparatively low angle. In parts where there is little rainwater, an almost smooth roof with a slight run-off provides satisfactory protection against an occasional downpour. Drainpipes take away the need for a sloping roof also.
A person that specializes in roof construction is called a roofer.The durability of an roof covering is a matter of matter because the rooftop is often the least accessible part of the building for purposes of repair and renewal, while its destruction 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 your roof covering are a consideration in its structure and the decision of roofing material.Some roofer materials, those of natural fibrous material especially, such as thatch, have excellent insulating properties. For all those that do not, extra insulation is often installed under the outside 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 temperature and cold, noises, dirt and often from the droppings and lice of wild birds who frequently choose roofs as nesting places.
Concrete tiles can be used as insulation. When installed leaving a space between the tiles and the roofing surface, it can reduce heating system caused by sunlight.Types of insulation are believed or plastic sheeting, with a reflective surface sometimes, 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 progressively more, and sometimes are mandated by local codes. Cool roofs are thought as roofs with both high reflectivity and high thermal emittance.
Poorly insulated and ventilated roofer can have problems with problems like the formation of ice dams round the overhanging eaves in winter, causing drinking water from melted snow on top elements of the rooftop to penetrate the roofing material. Ice dams happen when warmth escapes through the uppermost area of the roof, and the snow at those items melts, refreezing as it drips along the shingles, and collecting in the form of ice at the lower points. This can cause structural harm from stress, including the devastation of drainage and gutter systems.
