A rooftop is part of any building envelope. It's the covering on the uppermost part of any building or shelter which gives protection from pets and weather, notably rain or snow, but also heat, wind and sunlight. The term denotes the framing or structure which facilitates that covering also.[1]The characteristics of an roof are dependent upon the goal of the building it covers, the available roof covering materials and the neighborhood traditions of building and wider ideas of architectural design and practice and may also be governed by local or national legislation. In most countries a roof protects against rain primarily. 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 many parts of the world ceramic tiles have been the predominant roofer materials for centuries, if not millennia. Other roof materials include asphalt, coal tar pitch, EPDM silicone, Hypalon, reboundable foam, PVC, slate, Teflon cloth, TPO, and hardwood shingles and shakes.
The construction of your roof depends upon its method of support and how the underneath space is bridged and whether or not the rooftop is pitched. The pitch is the perspective at which the roof increases from its least expensive to highest point. Most US local structures, except in very dried up areas, has roofs that are sloped, or pitched. Although modern development elements such as drainpipes might remove the need for pitch, roofs are pitched for reasons of traditions and aesthetics. So the pitch is partly dependent after stylistic factors, also to do with practicalities partially.
Some types of roofer, for example thatch, need a steep pitch in order to be waterproof and durable. Other styles of roofing, for example pantiles, are unstable over a steeply pitched roof but provide excellent weather protection at a relatively low angle. In regions where there is little rain, an almost chiseled roof with a slight run-off provides satisfactory protection against an intermittent downpour. Drainpipes remove the need for a sloping roofing also.
A person that specializes in roof covering construction is named a roofer.The durability of any roof is a matter of concern because the roof structure is often the least accessible part of a building for purposes of repair and renewal, while its damage or damage can have serious effects.
Because the reason for a roof covering is to protect people and their possessions from climatic elements, the insulating properties of a roof are a concern in its composition and the choice of roofing materials.Some roof covering materials, particularly those of natural fibrous material, such as thatch, have excellent insulating properties. For all those that not, extra insulation is installed under the exterior 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 warmth and cold, noise, dirt and grime and often from the droppings and lice of birds who frequently choose roofs as nesting places.
Cement tiles can be used as insulation. When installed going out of a space between your tiles and the roofing surface, it can reduce heat caused by the sun.Types of insulation are sensed or plastic material 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 may be inserted or sprayed into roof cavities. So called Cool roofs are becoming more and more popular, and in some full 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 can suffer from problems like the formation of ice dams round the overhanging eaves in winter, causing water from melted snow on higher parts of the rooftop to penetrate the roofing materials. Ice dams appear when warmth escapes through the uppermost part of the roof, and the snow at those points melts, refreezing as it drips across the shingles, and collecting in the form of ice at the lower points. This can lead to structural destruction from stress, including the destruction of drainage and gutter systems.
