A roof top is part of a building envelope. It is the covering on the uppermost part of your building or shelter which provides protection from 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 a roof are based mostly upon the goal of the building it addresses, 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 against rain primarily. A verandah may be roofed with material that protects against sunlight but admits the other elements. The roof of any garden conservatory protects plants from cold, wind, and rain, but admits light.

In many parts of the global world ceramic tiles have been the predominant roof covering material for centuries, if not millennia. Other roof covering materials include asphalt, coal tar pitch, EPDM rubber, Hypalon, reboundable foam, PVC, slate, Teflon textile, TPO, and solid 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 roof covering is pitched. The pitch is the position of which the roof rises from its most affordable to highest point. Most US local architecture, except in very dried out areas, 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 appearance and traditions. So the pitch is partly dependent upon stylistic factors, also to do with practicalities partially.
Some types of roofing, for example thatch, need a steep pitch in order to be durable and waterproof. 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 rain, an almost level roof with hook run-off provides enough protection against an occasional downpour. Drainpipes also remove the dependence on a sloping roof.
A person that specializes in roof covering construction is called a roofer.The durability of your roof is a matter of matter because the roof covering is often the least accessible part of any building for purposes of repair and renewal, while its harm or devastation can have serious results.
Because the purpose of a roof structure is to protect people and their belongings from climatic elements, the insulating properties of any roofing are a factor in its composition 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 outer coating. In developed countries, the majority of dwellings have a ceiling installed under the structural members of the roof. The goal of a ceiling is to insulate against warmth and cold, sound, mud and frequently from the lice and droppings of wild birds who frequently choose roofs as nesting places.
Cement tiles can be utilized as insulation. When installed going out of a space between your tiles and the roof surface, it can reduce heating caused by the sun.Forms of insulation are sensed or plastic material sheeting, with a reflective surface sometimes, installed directly 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 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 roofer can suffer from problems like the formation of snow dams throughout the overhanging eaves in winter, causing drinking water from melted snow on top elements of the roof to penetrate the roofing material. Ice dams arise when heating escapes through the uppermost part of the roof, and the snow at those details melts, refreezing as it drips over the shingles, and collecting by means of ice at the lower points. This may result in structural harm from stress, including the devastation of gutter and drainage systems.
