A roof 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, notably rain or snow, but heat also, sunlight and wind. The word denotes the framing or framework which facilitates that covering also.[1]The characteristics of any roof are centered upon the goal of the building it protects, the available roofer materials and the neighborhood traditions of structure and wider ideas of architectural design and practice and could also be governed by local or national legislation. In most countries a roof protects against rain primarily. A verandah might be roofed with materials that defends against natural light but admits the other elements. The roof of a 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 roofer 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 lumber shakes and shingles.
The construction of a roof is determined by its approach to support and how the underneath space is bridged and set up roof top is pitched. The pitch is the perspective at which the roof rises from its least expensive to highest point. Most US local structures, except in very dry out regions, has roofs that are sloped, or pitched. Although modern structure elements such as drainpipes might take away the dependence on pitch, roofs are pitched for reasons of looks and tradition. So the pitch is dependent after stylistic factors partly, and to do with practicalities partially.
Some types of roof covering, for example thatch, need a steep pitch to become waterproof and durable. Other types of roofing, for example pantiles, are unstable over a steeply pitched roof but provide excellent weather protection at a relatively low angle. In locations where there is little rainfall, an almost smooth roof with hook run-off provides enough protection against an occasional downpour. Drainpipes take away the need for a sloping roof covering also.
A person that specializes in rooftop construction is named a roofer.The durability of the roof is a matter of concern because the roofing is usually the least accessible part of your building for purposes of repair and renewal, while its devastation or harm can have serious effects.
Because the reason for a roof top is to safeguard people and their belongings from climatic elements, the insulating properties of your roof covering are a awareness in its composition and the choice of roofing materials.Some roof covering materials, those of natural fibrous material specifically, such as thatch, have excellent insulating properties. For those that do not, extra insulation is installed under the outer part often. In developed countries, nearly all dwellings have a ceiling installed under the structural members of the roof. The purpose of a ceiling is to insulate against heating and cold, noises, dirt and grime and frequently from the lice and droppings of birds who frequently choose roofs as nesting places.
Concrete tiles can be utilized as insulation. When installed leaving a space between the tiles and the roofing surface, it can reduce heat caused by the sun.Types of insulation are vinyl or experienced sheeting, with a reflective surface sometimes, installed below the tiles or other materials immediately; 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 sometimes are mandated by local codes. Cool roofs are defined as roofs with both high reflectivity and high thermal emittance.
Poorly covered and ventilated roofing can suffer from problems including the formation of glaciers dams around the overhanging eaves in cold weather, causing water from melted snow on top elements of the roofing to penetrate the roofing materials. Ice dams appear when heat escapes through the uppermost area of the roof, and the snow at those true tips melts, refreezing as it drips across the shingles, and collecting in the form of ice at the lower points. This may cause structural damage from stress, like the damage of drainage and gutter systems.
