A roof is part of an building envelope. It's the covering on the uppermost part of a building or shelter which gives protection from animals and weather, rain or snow notably, but heat also, wind and sunlight. The word denotes the framing or structure which helps that covering also.[1]The characteristics of an roof are based mostly upon the goal of the building that it includes, the available roofing materials and the neighborhood traditions of building and wider principles of architectural design and practice and may also be governed by local or nationwide legislation. In most countries a roof protects mostly against rain. A verandah might be roofed with material that protects against sun rays but admits the other elements. The roof of a garden conservatory protects plants from cold, wind, and rain, but admits light.Shack made of date hand branches at Neot Semadar, IsraelA roof top may provide additional living space, for example a roof garden.The elements in the design of a roof are:the materialthe constructionthe durabilityThe material of a roof may range from banana leaves, wheaten straw or seagrass to laminated glass, copper (see: copper roofer), aluminium sheeting and pre-cast cement. In lots of parts of the entire world ceramic tiles have been the predominant roofing material for centuries, if not millennia. Other roof covering materials include asphalt, coal tar pitch, EPDM rubber, Hypalon, polyurethane foam, PVC, slate, Teflon cloth, TPO, and real wood shakes and shingles.The construction of your roof depends upon its approach to support and how the underneath space is bridged and set up roof structure is pitched. The pitch is the position at which the roof goes up from its minimum to highest point. Most US home architecture, except in very dry out locations, has roofs that are sloped, or pitched. Although modern engineering elements such as drainpipes may remove the need for pitch, roofs are pitched for reasons of tradition and appearance. So the pitch is dependent upon stylistic factors partly, and partially regarding practicalities.Some types of roofing, for example thatch, need a steep pitch in order to be durable and waterproof. 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 regions where there is little rainwater, an almost toned roof with hook run-off provides satisfactory protection against an occasional downpour. Drainpipes remove the dependence on a sloping roof structure also.A person that specializes in roof structure construction is named a roofer.The durability of an roof covering is a subject of concern because the roof top is often the least accessible part of an building for purposes of repair and renewal, while its damage or destruction can have serious effects.Because the purpose of a roof is to safeguard people and their property from climatic elements, the insulating properties of the rooftop are a concern in its framework and the decision of roofing materials.Some roofer materials, specifically those of natural fibrous materials, such as thatch, have excellent insulating properties. For all those that not, extra insulation is installed under the external part often. In developed countries, nearly all 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, mud and frequently from the lice and droppings of wild birds who frequently choose roofs as nesting places.Cement tiles can be utilized as insulation. When installed departing a space between your tiles and the roof surface, it can reduce warming caused by sunlight.Types of insulation are clear plastic or experienced 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 are becoming progressively more popular, and occasionally 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 have problems with problems like the formation of ice dams across the overhanging eaves in cold weather, causing normal water from melted snow on higher parts of the roof covering to permeate the roofing material. Ice dams take place when heat escapes through the uppermost part of the roof, and the snow at those true points melts, refreezing as it drips along the shingles, and collecting in the form of ice at the low points. This may bring about structural harm from stress, like the destruction of drainage and gutter systems.
