Roofing, by definition, is the covering of a structure, composed of all structures and materials needed to support it upon the structure’s outer wall, providing maximum protection from the elements, rain, snow, sun, extreme temperatures, and external threats (wind, ice, snow) storm damage exoerts. A roof also forms part of the outer protective envelope of any building. A well-functioning roof, properly installed and maintained, increases the overall value of a property as well as its efficiency in terms of energy consumption. A property with a properly installed and maintained roof also provides a safe, healthy environment for its residents.
There are two main types of roofing materials used for residential and commercial applications. These are the flat roof and the slate roof. The flat roofing system is composed of a number of flat roofing systems attached to a single central support. The flat roofing system is usually less stable and more susceptible to failure due to wind and weather. Moreover, such systems generally lack in the ability to provide thermal insulation; thus exposing the occupants to increased heating and cooling costs.
Moreover, the flat roofs are often exposed to a greater degree of UV radiation, reducing the life of these roofing materials considerably, particularly for people who spend a great deal of time indoors. Another important disadvantage of flat roofing systems is that they have a short life expectancy (typically between fifteen and twenty years). Finally, such systems are extremely susceptible to heavy winds.
