A roof structure is part of the building envelope. It is the covering on the uppermost part of a building or shelter which gives protection from animals and weather, rain or snow notably, but also heat, wind and sunlight. The term denotes the framing or framework which supports that covering also.[1]The characteristics of a roof are based mostly upon the goal of the building that it protects, the available roof materials and the neighborhood traditions of construction and wider principles of architectural design and practice and could also be governed by local or countrywide legislation. In most countries a roof protects primarily against rain. A verandah may be roofed with material that protects against sunlight but admits the other elements. The roof of a garden conservatory protects plants from cold, wind, and rain, but admits light.

In many parts of the entire world ceramic tiles have been the predominant roofing material for centuries, if not millennia. Other roof materials include asphalt, coal tar pitch, EPDM silicone, Hypalon, reboundable foam, PVC, slate, Teflon fabric, TPO, and hardwood shingles and shakes.
The construction of any roof depends upon its approach to support and how the underneath space is bridged and set up roof top is pitched. The pitch is the viewpoint at which the roof rises from its minimum to highest point. Most US domestic structures, except in very dried up locations, has roofs that are sloped, or pitched. Although modern engineering elements such as drainpipes may take away the need for pitch, roofs are pitched for reasons of custom and appearance. So the pitch is partly dependent after stylistic factors, and to do with practicalities partially.
Some types of roofing, for example thatch, need a steep pitch in order to be waterproof and durable. Other styles of roofing, for example pantiles, are unstable on the steeply pitched roof but provide excellent weather protection at a relatively low angle. In regions where there is little rainfall, an almost even roof with a slight run-off provides enough protection against an occasional downpour. Drainpipes remove the dependence on a sloping roofing also.
Somebody who specializes in roof construction is named a roofer.The durability of any roof is a matter of matter because the roof structure is usually the least accessible part of a building for purposes of repair and renewal, while its destruction or destruction can have serious effects.
Because the reason for a roof covering is to protect people and their property from climatic elements, the insulating properties of your roof are a thought in its structure and the choice of roofing materials.Some roof materials, specifically those of natural fibrous materials, such as thatch, have excellent insulating properties. For all those that do not, extra insulation is installed under the exterior level often. 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 heat and cold, sound, mud and often 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 the tiles and the roofing surface, it can reduce heat caused by sunlight.Types of insulation are felt or clear plastic sheeting, sometimes with a reflective surface, installed directly below the tiles or other materials; 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 have become popular more and more, 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 covered and ventilated roof can suffer from problems including the formation of glaciers dams around the overhanging eaves in cold weather, causing normal water from melted snow on higher parts of the roof to penetrate the roofing material. Ice dams arise when high temperature escapes through the uppermost part of the roof, and the snow at those true details melts, refreezing as it drips across the shingles, and collecting in the form of ice at the low points. This may bring about structural damage from stress, including the destruction of gutter and drainage systems.
