A roof structure is part of an building envelope. It is the covering on the uppermost part of an building or shelter which provides protection from pets or animals and weather, rain or snow notably, but heat also, sunlight and wind. The word denotes the framing or framework which facilitates that covering also.[1]The characteristics of the roof are dependent upon the purpose of the building which it addresses, the available roofer materials and the neighborhood traditions of construction and wider concepts 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 your garden conservatory protects plants from cold, wind, and rain, but admits light.
Shack manufactured from date palm branches at Neot Semadar, IsraelA roofing might provide additional living space, for example a roof top garden.The elements in the design of a roofing are:the materialthe constructionthe durabilityThe material of your roof may range from banana leaves, wheaten straw or seagrass to laminated glass, copper (see: copper roof), aluminium sheeting and pre-cast concrete. In many parts of the entire world ceramic tiles have been the predominant roofing material for years and years, if not millennia. Other roofing materials include asphalt, coal tar pitch, EPDM plastic, Hypalon, polyurethane foam, PVC, slate, Teflon fabric, TPO, and real wood shingles and shakes.
The construction of the roof depends upon its approach to support and the way the underneath space is bridged and whether or not the roof is pitched. The pitch is the position at which the roof goes up from its least expensive to highest point. Most US local structures, except in very dried out regions, has roofs that are sloped, or pitched. Although modern construction elements such as drainpipes may remove the need for pitch, roofs are pitched for reasons of traditions and aesthetics. So the pitch is dependent after stylistic factors partly, and partially regarding practicalities.
Some types of roof, for example thatch, require a steep pitch to become waterproof and durable. Other types of roofing, for example pantiles, are unstable on a steeply pitched roof but provide excellent weather protection at a comparatively low angle. In regions where there is little rainwater, an almost even roof with a slight run-off provides satisfactory protection against an occasional downpour. Drainpipes take away the need for a sloping roof also.
A person that specializes in roof top construction is named a roofer.The durability of a roofing is a matter of concern because the roofing is often the least accessible part of an building for purposes of repair and renewal, while its damage or devastation can have serious results.
Because the reason for a roof top is to safeguard people and their possessions from climatic elements, the insulating properties of a roofing are a consideration in its framework and the decision of roofing material.Some roofer 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 outside layer 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 high temperature and cold, noises, dirt and often from the droppings and lice of wild birds who frequently choose roofs as nesting places.
Cement tiles can be utilized as insulation. When installed leaving a space between your tiles and the roof covering surface, it can reduce heat caused by the sun.Types of insulation are clear plastic or sensed 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 can be inserted or sprayed into roof cavities. So called Cool roofs are becoming popular ever more, and sometimes are mandated by local codes. Cool roofs are thought as roofs with both high reflectivity and high thermal emittance.
Poorly protected and ventilated roofing can suffer from problems including the formation of ice dams round the overhanging eaves in winter, causing drinking water from melted snow on higher elements 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 true factors melts, refreezing as it drips along the shingles, and collecting by means of ice at the lower points. This can cause structural harm from stress, including the devastation of gutter and drainage systems.
