A roof covering is part of your building envelope. It's the covering on the uppermost part of any building or shelter which provides protection from pets or animals and weather, notably rain or snow, but heat also, sunlight and wind. The word also denotes the framing or structure which supports that covering.[1]The characteristics of a roof are centered upon the purpose of the building so it covers, the available roofer materials and the local traditions of development and wider concepts of architectural design and practice and may also be governed by local or countrywide legislation. In most countries a roof protects against rain primarily. A verandah might be roofed with materials that helps to protect against sun light 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 planet ceramic tiles have been the predominant roofing materials for centuries, if not millennia. Other roofer materials include asphalt, coal tar pitch, EPDM plastic, Hypalon, polyurethane foam, PVC, slate, Teflon textile, TPO, and hardwood shakes and shingles.
The construction of any roof depends upon its method of support and how the underneath space is bridged and whether or not the roof structure is pitched. The pitch is the position at which the roof increases from its minimum to highest point. Most US domestic structures, except in very dry areas, has roofs that are sloped, or pitched. Although modern development elements such as drainpipes may remove the need for pitch, roofs are pitched for reasons of appearance and tradition. So the pitch is dependent after stylistic factors partly, and to do with practicalities partly.
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 the steeply pitched roof but provide excellent weather protection at a comparatively low angle. In regions where there is little rain, an almost toned roof with hook run-off provides adequate protection against an occasional downpour. Drainpipes also take away the need for a sloping roofing.
A person that specializes in rooftop construction is named a roofer.The durability of any roof is a matter of concern because the roof top is often the least accessible part of any building for purposes of repair and renewal, while its destruction or damage can have serious effects.
Because the reason for a roof covering is to safeguard people and their belongings from climatic elements, the insulating properties of an roof are a account in its framework and the choice of roofing material.Some roofer materials, especially those of natural fibrous materials, such as thatch, have excellent insulating properties. For those that not, extra insulation is often installed under the exterior level. In developed countries, nearly all dwellings have a ceiling installed under the structural members of the roof. The purpose of a roof is to insulate against heating and cold, noise, mud and frequently from the lice and droppings of parrots who frequently choose roofs as nesting places.
Concrete tiles can be used as insulation. When installed leaving a space between your tiles and the roofing surface, it can reduce heating up caused by the sun.Forms of insulation are felt or clear plastic sheeting, sometimes with a reflective surface, 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 progressively, and sometimes are mandated by local codes. Cool roofs are defined as roofs with both high reflectivity and high thermal emittance.
Poorly covered and ventilated roofing can have problems with problems such as the formation of ice dams around the overhanging eaves in winter, causing water from melted snow on top elements of the roof structure to permeate the roofing materials. Ice dams occur when heating escapes through the uppermost part of the roof, and the snow at those true details melts, refreezing as it drips across the shingles, and collecting by means of ice at the low points. This may result in structural destruction from stress, like the devastation of gutter and drainage systems.
