A rooftop is part of a building envelope. It's the covering on the uppermost part of an building or shelter which gives protection from animals and weather, rain or snow notably, but heat also, sunlight and wind. The word also denotes the framing or structure which supports that covering.[1]The characteristics of an roof are centered upon the purpose of the building that this includes, the available roof covering materials and the local traditions of building and wider principles of architectural design and practice and could also be governed by local or nationwide legislation. In most countries a roof protects generally against rain. A verandah might be roofed with material that shields against sunlight but admits the other elements. The roof of an garden conservatory protects plants from cold, wind, and rain, but admits light.

In many parts of the globe ceramic tiles have been the predominant roof material for years and years, if not millennia. Other roofing materials include asphalt, coal tar pitch, EPDM silicone, Hypalon, polyurethane foam, PVC, slate, Teflon textile, TPO, and real wood shakes and shingles.
The construction of an roof depends upon its method of support and the way the underneath space is bridged and whether or not the roofing is pitched. The pitch is the viewpoint of which the roof rises from its minimum to highest point. Most US domestic architecture, except in very dried up regions, has roofs that are sloped, or pitched. Although modern structure elements such as drainpipes might remove the need for pitch, roofs are pitched for reasons of tradition and looks. So the pitch is dependent after stylistic factors partly, and to do with practicalities partially.
Some types of roofing, for example thatch, need 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 relatively low angle. In locations where there is little rain, an almost flat roof with a slight run-off provides sufficient protection against an occasional downpour. Drainpipes take away the need for a sloping roof structure also.
Somebody who specializes in roof construction is named a roofer.The durability of a roofing is a subject of concern because the roofing is often the least accessible part of an building for purposes of repair and renewal, while its harm or devastation can have serious effects.
Because the reason for a roof covering is to safeguard people and their property from climatic elements, the insulating properties of any roof structure are a consideration in its framework and the choice of roofing materials.Some roofing materials, especially those of natural fibrous materials, such as thatch, have excellent insulating properties. For those that not, extra insulation is installed under the external part often. 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 heating and cold, noises, mud and frequently from the lice and droppings of parrots who frequently choose roofs as nesting places.Concrete tiles can be utilized as insulation. When installed giving a space between your tiles and the roof surface, it can reduce warming caused by the sun.Types of insulation are clear plastic or thought sheeting, with a reflective surface sometimes, installed straight below the tiles or other material; 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 more and more popular, and occasionally are mandated by local codes. Cool roofs are defined as roofs with both high reflectivity and high thermal emittance.Poorly insulated and ventilated roofer can suffer from problems such as the formation of ice dams throughout the overhanging eaves in cold weather, causing drinking water from melted snow on higher elements of the roofing to permeate the roofing materials. Ice dams happen when warmth escapes through the uppermost area of the roof, and the snow at those things melts, refreezing as it drips across the shingles, and collecting in the form of ice at the lower points. This can result in structural damage from stress, including the devastation of gutter and drainage systems.
