A roof top is part of the building envelope. It is the covering on the uppermost part of any building or shelter which gives protection from family pets and weather, notably rain or snow, but heat also, wind and sunlight. The word also denotes the framing or structure which supports that covering.[1]The characteristics of a roof are reliant upon the purpose of the building so it addresses, the available roof materials and the local traditions of development and wider concepts of architectural design and practice and could also be governed by local or countrywide legislation. In most countries a roof protects primarily against rain. A verandah might be roofed with materials that shields against natural light but admits the other elements. The roof of a 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 roof covering material for years and years, if not millennia. Other roofing materials include asphalt, coal tar pitch, EPDM silicone, Hypalon, polyurethane foam, PVC, slate, Teflon cloth, TPO, and real wood shakes and shingles.
The construction of your roof depends upon its method of support and the way the underneath space is bridged and whether or not the rooftop is pitched. The pitch is the position at which the roof rises from its minimum to highest point. Most US local architecture, except in very dried out locations, has roofs that are sloped, or pitched. Although modern structure elements such as drainpipes may take away the need for pitch, roofs are pitched for reasons of appearance and tradition. So the pitch is dependent after stylistic factors partly, and partially to do with practicalities.
Some types of roofer, for example thatch, need a steep pitch in order to be waterproof and durable. Other types of roofing, for example pantiles, are unstable on 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 satisfactory protection against an occasional downpour. Drainpipes also remove the dependence on a sloping roof top.
Somebody who specializes in roof covering construction is called a roofer.The durability of an roof is a subject of matter because the roof covering is often the least accessible part of the building for purposes of repair and renewal, while its destruction or destruction can have serious results.
Because the reason for a roof is to safeguard people and their belongings from climatic elements, the insulating properties of an roof covering are a factor in its composition and the choice of roofing material.Some roofing materials, those of natural fibrous materials specifically, such as thatch, have excellent insulating properties. For those that not, extra insulation is installed under the outside coating 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, sound, mud and frequently from the lice and droppings 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 roof top surface, it can reduce heating caused by sunlight.Types of insulation are believed or plastic sheeting, sometimes with a reflective surface, installed straight below the tiles or other material; 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 significantly 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 insulated and ventilated roof covering can suffer from problems such as the formation of ice dams throughout the overhanging eaves in winter, causing drinking water from melted snow on higher elements of the rooftop to penetrate the roofing material. Ice dams arise when temperature escapes through the uppermost part of the roof, and the snow at those true tips melts, refreezing as it drips across the shingles, and collecting in the form of ice at the lower points. This may cause structural harm from stress, like the devastation of gutter and drainage systems.
