A roof structure is part of your building envelope. It is the covering on the uppermost part of any building or shelter which gives protection from pets and weather, rain or snow notably, but also heat, sunlight and wind. The word also denotes the framing or structure which supports that covering.[1]The characteristics of an roof are reliant upon the purpose of the building that it includes, the available roof covering materials and the local traditions of structure 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 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.

In many elements of the global 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 fabric, TPO, and hardwood shakes and shingles.
The construction of an roof depends upon its approach to support and how the underneath space is bridged and whether or not the roof covering is pitched. The pitch is the position of which the roof goes up from its minimum to highest point. Most US home structures, except in very dried parts, has roofs that are sloped, or pitched. Although modern engineering elements such as drainpipes might take away the need for pitch, roofs are pitched for reasons of looks and custom. So the pitch is dependent upon stylistic factors partly, also to do with practicalities partially.
Some types of roof covering, for example thatch, need a steep pitch to become durable and waterproof. Other types of roofing, for example pantiles, are unstable over a steeply pitched roof but provide excellent weather protection at a relatively low angle. In regions where there is little rainwater, an almost smooth roof with hook run-off provides adequate protection against an intermittent downpour. Drainpipes also remove the need for a sloping roofing.
A person that specializes in roof construction is named a roofer.The durability of the roof structure is a matter of concern because the roof is usually the least accessible part of any building for purposes of repair and renewal, while its damage or destruction can have serious results.
Because the reason for a roof structure is to protect people and their belongings from climatic elements, the insulating properties of any roof covering are a awareness in its composition and the choice of roofing materials.Some roofing materials, those of natural fibrous materials specifically, such as thatch, have excellent insulating properties. For all those that not, extra insulation is installed under the outer level often. In developed countries, the majority of dwellings have a ceiling installed under the structural members of the roof. The goal of a ceiling is to insulate against heating and cold, sound, mud and frequently from the lice and droppings of birds who frequently choose roofs as nesting places.
Concrete tiles can be used as insulation. When installed going out of a space between the tiles and the roof structure surface, it can reduce heating caused by sunlight.Types of insulation are plastic or thought sheeting, sometimes with a reflective surface, installed below the tiles or other materials immediately; 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 have become increasingly popular, and in some cases are mandated by local codes. Cool roofs are defined as roofs with both high reflectivity and high thermal emittance.
Poorly protected and ventilated roof can suffer from problems including the formation of glaciers dams throughout the overhanging eaves in winter, causing water from melted snow on upper parts of the roof structure to penetrate the roofing material. Ice dams arise when heating escapes through the uppermost area of the roof, and the snow at those details melts, refreezing as it drips over the shingles, and collecting by means of ice at the low points. This may lead to structural damage from stress, including the devastation of drainage and gutter systems.
