A roof is part of any building envelope. It's the covering on the uppermost part of a building or shelter which provides protection from animals and weather, rain or snow notably, but also heat, sunlight and wind. The word also denotes the framing or structure which supports that covering.[1]The characteristics of any roof are reliant upon the purpose of the building that it includes, 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 countrywide 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 your garden conservatory protects plants from cold, wind, and rain, but admits light.

In many parts of the planet ceramic tiles have been the predominant roof material for years and years, if not millennia. Other roofing materials include asphalt, coal tar pitch, EPDM silicone, Hypalon, polyurethane foam, PVC, slate, Teflon textile, TPO, and timber shingles and shakes.
The construction of an roof is determined by its method of support and the way the underneath space is bridged and set up roof covering is pitched. The pitch is the position of which the roof goes up from its most affordable to highest point. Most US local structures, except in very dry parts, has roofs that are sloped, or pitched. Although modern construction elements such as drainpipes may remove the need for pitch, roofs are pitched for reasons of aesthetics and custom. 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 on a steeply pitched roof but provide excellent weather protection at a relatively low angle. In locations where there is little rainwater, an almost even 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 roof structure construction is named a roofer.The durability of an roof top is a matter of concern because the roof top is usually the least accessible part of a building for purposes of repair and renewal, while its destruction or destruction can have serious results.
Because the purpose of a roof top is to protect people and their property from climatic elements, the insulating properties of your roofing are a consideration in its structure and the choice of roofing materials.Some roofer materials, specifically those of natural fibrous material, such as thatch, have excellent insulating properties. For those that do not, extra insulation is often installed under the exterior covering. In developed countries, nearly all dwellings have a ceiling installed under the structural members of the roof. The goal of a ceiling is to insulate against temperature and cold, sound, dirt and often from the droppings and lice of birds who frequently choose roofs as nesting places.
Concrete tiles can be utilized as insulation. When installed departing a space between your tiles and the roof top surface, it can reduce heating caused by sunlight.Forms of insulation are believed or cheap 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 are becoming progressively 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 insulated and ventilated roofer can suffer from problems like the formation of snow dams around the overhanging eaves in winter, causing water from melted snow on upper parts of the roof to penetrate the roofing material. Ice dams arise when temperature escapes through the uppermost area of the roof, and the snow at those points melts, refreezing as it drips across the shingles, and collecting by means of ice at the low points. This can lead to structural damage from stress, including the damage of gutter and drainage systems.
