A roof 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, notably rain or snow, 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 purpose of the building which it protects, the available roof covering materials and the local traditions of structure and wider principles of architectural design and practice and could also be governed by local or national legislation. In most countries a roof protects mainly against rain. A verandah might be roofed with materials that helps to protect against sun light but admits the other elements. The roof of your garden conservatory protects plants from cold, wind, and rain, but admits light.
Shack made of date hand branches at Neot Semadar, IsraelA roof may provide additional liveable space, for example a rooftop garden.The elements in the look of a roof are:the materialthe constructionthe durabilityThe material of a roof may range from banana leaves, wheaten straw or seagrass to laminated a glass, copper (see: copper roof covering), aluminium sheeting and pre-cast cement. In many parts of the planet ceramic tiles have been the predominant roof materials for centuries, if not millennia. Other roofing materials include asphalt, coal tar pitch, EPDM plastic, Hypalon, polyurethane foam, PVC, slate, Teflon fabric, TPO, and hardwood shingles and shakes.
The construction of your roof is determined by its method of support and the way the underneath space is bridged and whether or not the roof structure is pitched. The pitch is the position at which the roof increases from its least expensive to highest point. Most US domestic structures, except in very dried up parts, has roofs that are sloped, or pitched. Although modern engineering elements such as drainpipes may remove the dependence on pitch, roofs are pitched for reasons of appearance and custom. So the pitch is dependent upon stylistic factors partly, and partially to do with practicalities.
Some types of roof covering, for example thatch, require 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 comparatively low angle. In areas where there is little rainwater, an almost toned roof with hook run-off provides adequate protection against an occasional downpour. Drainpipes also take away the dependence on a sloping roofing.
Somebody who specializes in roof covering construction is named a roofer.The durability of any rooftop is a subject of concern because the roof is usually the least accessible part of your building for purposes of repair and renewal, while its destruction or damage can have serious results.
Because the purpose of a roof top is to safeguard people and their possessions from climatic elements, the insulating properties of a roof are a consideration in its framework and the decision of roofing material.Some roofer materials, specifically those of natural fibrous material, such as thatch, have excellent insulating properties. For all those that not, extra insulation is installed under the outside covering often. 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 heat and cold, noises, mud and frequently from the droppings and lice of wild birds who frequently choose roofs as nesting places.
Concrete tiles can be used as insulation. When installed departing a space between your tiles and the roof surface, it can reduce heating up caused by sunlight.Forms of insulation are clear plastic or sensed sheeting, with a reflective surface sometimes, installed straight 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 popular, and occasionally are mandated by local codes. Cool roofs are thought as roofs with both high reflectivity and high thermal emittance.
Poorly protected and ventilated roofer can suffer from problems like the formation of ice dams surrounding the overhanging eaves in winter, causing normal water from melted snow on upper parts of the roof covering to permeate the roofing material. Ice dams occur when high temperature escapes through the uppermost area of the roof, and the snow at those details melts, refreezing as it drips across the shingles, and collecting by means of ice at the low points. This can cause structural destruction from stress, including the destruction of gutter and drainage systems.
