A roof covering is part of the building envelope. It is the covering on the uppermost part of the building or shelter which provides protection from pets or animals and weather, rain or snow notably, but also heat, wind and sunlight. The word also denotes the framing or structure which supports that covering.[1]The characteristics of a roof are centered upon the goal of the building which it protects, the available roofer materials and the local traditions of construction and wider ideas of architectural design and practice and may 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 any garden conservatory protects plants from cold, wind, and rain, but admits light.

In many parts of the globe ceramic tiles have been the predominant roofing materials for centuries, if not millennia. Other roof materials include asphalt, coal tar pitch, EPDM rubber, Hypalon, reboundable foam, PVC, slate, Teflon cloth, TPO, and wood shakes and shingles.
The construction of any roof is determined by its approach to support and how the underneath space is bridged and set up roof structure is pitched. The pitch is the viewpoint at which the roof goes up from its lowest to highest point. Most US home structures, except in very dried parts, has roofs that are sloped, or pitched. Although modern development elements such as drainpipes might remove the dependence on pitch, roofs are pitched for reasons of traditions and aesthetics. So the pitch is dependent after stylistic factors partly, also to do with practicalities partially.
Some types of roofer, for example thatch, require a steep pitch in order to be waterproof and durable. Other types of roofing, for example pantiles, are unstable on the 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 hook run-off provides adequate protection against an occasional downpour. Drainpipes remove the dependence on a sloping roof also.
Somebody who specializes in roof construction is named a roofer.The durability of your rooftop is a subject of concern because the roofing is usually the least accessible part of a building for purposes of repair and renewal, while its damage or damage can have serious effects.
Because the purpose of a roofing is to safeguard people and their possessions from climatic elements, the insulating properties of a rooftop are a consideration in its framework and the decision of roofing material.Some roof materials, those of natural fibrous material particularly, such as thatch, have excellent insulating properties. For those that not, extra insulation is installed under the external level 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 high temperature and cold, noises, dirt and grime and frequently from the lice and droppings of wild birds who frequently choose roofs as nesting places.
Concrete tiles can be utilized as insulation. When installed departing a space between the tiles and the roof surface, it can reduce heating up caused by sunlight.Forms of insulation are clear plastic or believed sheeting, sometimes with a reflective surface, installed below the tiles or other material straight; 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 more and more popular, and in some cases are mandated by local codes. Cool roofs are thought as roofs with both high reflectivity and high thermal emittance.
Poorly protected and ventilated roof can have problems with problems including the formation of glaciers dams surrounding the overhanging eaves in cold weather, causing water from melted snow on higher parts of the rooftop to permeate the roofing materials. Ice dams occur when warmth escapes through the uppermost area of the roof, and the snow at those things melts, refreezing as it drips along the shingles, and collecting in the form of ice at the lower points. This may result in structural damage from stress, including the destruction of drainage and gutter systems.
