A roof covering is part of a building envelope. It is the covering on the uppermost part of the building or shelter which provides protection from pets and weather, notably rain or snow, but also heat, sunlight and wind. The term also denotes the framing or structure which supports that covering.[1]The characteristics of your roof are centered upon the goal of the building so it addresses, the available roofing materials and the local traditions of building and wider concepts of architectural design and practice and may also be governed by local or nationwide legislation. In most countries a roof protects primarily against rain. A verandah may be roofed with material that protects against sunlight but admits the other elements. The roof of any garden conservatory protects plants from cold, wind, and rain, but admits light.

In many parts of the global world ceramic tiles have been the predominant roof materials for centuries, if not millennia. Other roofing materials include asphalt, coal tar pitch, EPDM rubber, Hypalon, polyurethane foam, PVC, slate, Teflon fabric, TPO, and solid wood shakes and shingles.
The construction of the roof is determined by its approach to support and the way the underneath space is bridged and whether or not the roof top is pitched. The pitch is the angle at which the roof increases from its lowest to highest point. Most US local architecture, except in very dry out locations, 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 custom and appearance. So the pitch is dependent after stylistic factors partly, also to do with practicalities partly.
Some types of roofing, for example thatch, require a steep pitch to become durable and waterproof. 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 rain, an almost chiseled roof with hook run-off provides adequate protection against an occasional downpour. Drainpipes take away the need for a sloping roofing also.
A person that specializes in rooftop construction is named a roofer.The durability of your roofing is a matter of matter because the roof covering is often the least accessible part of an building for purposes of repair and renewal, while its destruction or harm can have serious results.
Because the reason for a roofing is to safeguard people and their property from climatic elements, the insulating properties of your roof are a concern in its composition and the choice 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 often installed under the outside coating. In developed countries, the majority of 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, dirt and often from the lice and droppings of birds who frequently choose roofs as nesting places.
Concrete tiles can be used as insulation. When installed departing a space between the tiles and the roofing surface, it can reduce heating up caused by sunlight.Types of insulation are sensed or plastic material 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 popular ever more, and occasionally are mandated by local codes. Cool roofs are defined as roofs with both high reflectivity and high thermal emittance.
Poorly protected and ventilated roofer can suffer from problems including the formation of glaciers dams throughout the overhanging eaves in cold weather, causing normal water from melted snow on top elements of the roof to permeate the roofing materials. Ice dams take place when high temperature escapes through the uppermost part of the roof, and the snow at those true points melts, refreezing as it drips over the shingles, and collecting by means of ice at the low points. This may result in structural harm from stress, including the damage of gutter and drainage systems.
