A roof is part of your building envelope. It is the covering on the uppermost part of your building or shelter which gives protection from pets and weather, rain or snow notably, but heat also, wind and sunlight. The term denotes the framing or framework which facilitates that covering also.[1]The characteristics of any roof are centered upon the goal of the building that it addresses, the available roofing materials and the neighborhood traditions of structure and wider principles 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 an garden conservatory protects plants from cold, wind, and rain, but admits light.

In lots of parts of the entire world ceramic tiles have been the predominant roofer materials for centuries, if not millennia. Other roofing materials include asphalt, coal tar pitch, EPDM plastic, Hypalon, reboundable foam, PVC, slate, Teflon textile, TPO, and lumber 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 top is pitched. The pitch is the position of which the roof goes up from its lowest to highest point. Most US home architecture, except in very dry out locations, has roofs that are sloped, or pitched. Although modern structure elements such as drainpipes may take away the dependence on pitch, roofs are pitched for reasons of appearance and tradition. So the pitch is dependent upon stylistic factors partly, and to do with practicalities partly.
Some types of roofing, for example thatch, require a steep pitch in order to be durable and waterproof. Other types of roofing, for example pantiles, are unstable over a steeply pitched roof but provide excellent weather protection at a comparatively low angle. In parts where there is little rainwater, an almost chiseled roof with a slight run-off provides enough protection against an occasional downpour. Drainpipes take away the need for a sloping roof covering also.
Somebody who specializes in roof construction is called a roofer.The durability of any roof is a matter of matter because the roof structure is often the least accessible part of the building for purposes of repair and renewal, while its harm or destruction can have serious effects.
Because the purpose of a roof is to safeguard people and their possessions from climatic elements, the insulating properties of the roof top are a awareness in its framework and the choice of roofing material.Some roof covering materials, those of natural fibrous materials particularly, such as thatch, have excellent insulating properties. For all those that do not, extra insulation is often installed under the outer covering. In developed countries, the majority of dwellings have a ceiling installed under the structural members of the roof. The goal of a roof is to insulate against temperature and cold, noise, mud and frequently from the droppings and lice of birds who frequently choose roofs as nesting places.
Concrete tiles can be utilized as insulation. When installed departing a space between your tiles and the roofing surface, it can reduce heating caused by sunlight.Types of insulation are plastic material or sensed sheeting, with a reflective surface sometimes, installed below the tiles or other materials straight; 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 have become progressively popular, and sometimes are mandated by local codes. Cool roofs are defined as roofs with both high reflectivity and high thermal emittance.
Poorly covered and ventilated roof covering can suffer from problems including the formation of glaciers dams round the overhanging eaves in winter, causing normal water from melted snow on top elements of the roof top to penetrate the roofing materials. Ice dams arise when heat escapes through the uppermost part of the roof, and the snow at those tips melts, refreezing as it drips across the shingles, and collecting by means of ice at the low points. This can bring about structural damage from stress, like the devastation of drainage and gutter systems.
