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

In lots of parts of the global world ceramic tiles have been the predominant roofing materials for centuries, if not millennia. Other roof materials include asphalt, coal tar pitch, EPDM silicone, Hypalon, reboundable foam, PVC, slate, Teflon fabric, TPO, and wood shakes and shingles.
The construction of your roof depends upon its approach to support and how the underneath space is bridged and whether or not the roofing is pitched. The pitch is the perspective of which the roof increases from its most affordable to highest point. Most US domestic architecture, except in very dry out locations, has roofs that are sloped, or pitched. Although modern structure elements such as drainpipes might take away the need for pitch, roofs are pitched for reasons of aesthetics and custom. So the pitch is dependent after stylistic factors partly, and partially regarding practicalities.
Some types of roofer, for example thatch, need a steep pitch to become 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 areas where there is little rainwater, an almost flat roof with a slight run-off provides enough protection against an occasional downpour. Drainpipes remove the dependence on a sloping roof covering also.
A person that specializes in roofing construction is named a roofer.The durability of your roof top is a matter of concern because the roof covering is often the least accessible part of an building for purposes of repair and renewal, while its destruction or damage can have serious results.
Because the reason for a roof top is to safeguard people and their property from climatic elements, the insulating properties of your roof covering are a account in its composition and the decision of roofing material.Some roofer materials, those of natural fibrous material specifically, such as thatch, have excellent insulating properties. For those that do not, extra insulation is installed under the outside layer often. 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 heating and cold, noises, dirt and grime and frequently from the lice and droppings of birds who frequently choose roofs as nesting places.
Cement tiles can be used as insulation. When installed leaving a space between the tiles and the roof covering surface, it can reduce heating up caused by the sun.Types of insulation are plastic or thought sheeting, sometimes with a reflective surface, installed below the tiles or other material immediately; 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 popular increasingly, 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 roofing can suffer from problems such as the formation of ice dams across the overhanging eaves in winter, causing normal water from melted snow on upper parts of the rooftop to permeate the roofing material. Ice dams happen when temperature escapes through the uppermost part of the roof, and the snow at those true things melts, refreezing as it drips along the shingles, and collecting in the form of ice at the lower points. This may lead to structural harm from stress, including the devastation of drainage and gutter systems.
