A roof structure is part of your building envelope. It is the covering on the uppermost part of a building or shelter which provides protection from pets and weather, rain or snow notably, but heat also, wind and sunlight. The term denotes the framing or structure which supports that covering also.[1]The characteristics of the roof are centered upon the purpose of the building which it covers, the available roof materials and the neighborhood traditions of building and wider principles of architectural design and practice and could also be governed by local or countrywide legislation. In most countries a roof protects against rain primarily. A verandah might be roofed with materials that shields against sunshine 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 globe ceramic tiles have been the predominant roofer materials for years and years, if not millennia. Other roofing materials include asphalt, coal tar pitch, EPDM plastic, Hypalon, reboundable foam, PVC, slate, Teflon cloth, TPO, and lumber shingles and shakes.
The construction of a roof depends upon its method of support and how the underneath space is bridged and whether or not the rooftop is pitched. The pitch is the viewpoint of which the roof goes up from its most affordable to highest point. Most US home structures, except in very dried up parts, has roofs that are sloped, or pitched. Although modern building elements such as drainpipes might take away the need for pitch, roofs are pitched for reasons of looks and tradition. So the pitch is dependent upon stylistic factors partly, and partially regarding 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 over a steeply pitched roof but provide excellent weather protection at a relatively low angle. In areas where there is little rainfall, an almost smooth roof with a slight run-off provides adequate protection against an occasional downpour. Drainpipes take away the dependence on a sloping roof covering also.
A person that specializes in roofing construction is named a roofer.The durability of an roof is a subject of concern because the roofing is usually the least accessible part of your building for purposes of repair and renewal, while its damage or damage can have serious results.
Because the purpose of a roof top is to safeguard people and their property from climatic elements, the insulating properties of any roof structure are a concern in its structure and the decision of roofing material.Some roofer materials, those of natural fibrous materials specifically, such as thatch, have excellent insulating properties. For those that do not, extra insulation is installed under the exterior part often. In developed countries, nearly all dwellings have a ceiling installed under the structural members of the roof. The goal of a roof is to insulate against heating and cold, noises, dirt and grime and often from the lice and droppings of parrots who frequently choose roofs as nesting places.
Concrete tiles can be utilized as insulation. When installed going out of a space between the tiles and the roof structure surface, it can reduce heat caused by the sun.Forms of insulation are thought or cheap sheeting, sometimes with a reflective surface, 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 popular progressively, and in some full cases are mandated by local codes. Cool roofs are thought as roofs with both high reflectivity and high thermal emittance.
Poorly covered and ventilated roofing can have problems with problems like the formation of ice dams across the overhanging eaves in winter, causing water from melted snow on top parts of the roof top to penetrate the roofing materials. Ice dams appear when temperature escapes through the uppermost area of the roof, and the snow at those items melts, refreezing as it drips over the shingles, and collecting by means of ice at the lower points. This may lead to structural harm from stress, including the damage of drainage and gutter systems.
