A roof top is part of any building envelope. It is the covering on the uppermost part of your building or shelter which gives protection from pets and weather, rain or snow notably, but also heat, sunlight and wind. The term denotes the framing or framework which facilitates that covering also.[1]The characteristics of your roof are centered upon the goal of the building which it addresses, the available roofing materials and the neighborhood traditions of development and wider principles of architectural design and practice and may also be governed by local or nationwide legislation. In most countries a roof protects generally against rain. 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 lots of parts of the world ceramic tiles have been the predominant roof covering materials for years and years, if not millennia. Other roof covering materials include asphalt, coal tar pitch, EPDM silicone, Hypalon, reboundable foam, PVC, slate, Teflon fabric, TPO, and real wood shakes and shingles.
The construction of any roof depends upon its approach to support and how the underneath space is bridged and set up rooftop is pitched. The pitch is the perspective at which the roof goes up from its minimum to highest point. Most US domestic structures, except in very dried regions, has roofs that are sloped, or pitched. Although modern engineering elements such as drainpipes might take away the dependence on pitch, roofs are pitched for reasons of custom and aesthetics. So the pitch is partly dependent upon stylistic factors, and partially to do with practicalities.
Some types of roofing, for example thatch, need a steep pitch in order to be durable and waterproof. Other styles of roofing, for example pantiles, are unstable on the steeply pitched roof but provide excellent weather protection at a comparatively low angle. In locations where there is little rainwater, an almost flat roof with hook run-off provides adequate protection against an intermittent downpour. Drainpipes take away the dependence on a sloping roof structure also.
Somebody who specializes in roof construction is called a roofer.The durability of a roofing is a subject of matter because the roof covering is usually the least accessible part of any building for purposes of repair and renewal, while its devastation or damage can have serious effects.
Because the purpose of a roof top is to protect people and their property from climatic elements, the insulating properties of any rooftop are a thought in its structure and the decision of roofing material.Some roof materials, specifically those of natural fibrous material, such as thatch, have excellent insulating properties. For all those that do not, extra insulation is installed under the exterior covering often. In developed countries, the majority of dwellings have a ceiling installed under the structural members of the roof. The purpose of a ceiling is to insulate against warmth and cold, sound, dirt 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 departing a space between your tiles and the roof top surface, it can reduce heating up caused by sunlight.Forms of insulation are thought or cheap 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 can be inserted or sprayed into roof cavities. So called Cool roofs have become popular more and more, and in some full cases are mandated by local codes. Cool roofs are thought as roofs with both high reflectivity and high thermal emittance.
Poorly covered and ventilated roof covering can suffer from problems including the formation of glaciers dams throughout the overhanging eaves in cold weather, causing drinking water from melted snow on higher elements of the roof top to permeate the roofing materials. Ice dams happen when heat escapes through the uppermost part of the roof, and the snow at those true things melts, refreezing as it drips over the shingles, and collecting by means of ice at the lower points. This may result in structural harm from stress, like the destruction of drainage and gutter systems.
