Roofing – Its Function And Purpose
Roofing is usually the highest part covering a structure, including all additional structures and materials necessary to support it, on uprights or on the roofs of buildings, providing protection from the elements, heat, sunlight, wind, and snow. A good roofing system is designed to provide protection in several different ways. A roof protects the structure from the weather while at the same time acting to conserve heat. It also provides insulation against heat loss from the inside of the structure. A good roof will also have vents and air vents that allow the heat to escape and cool the interior of a structure.

In addition to providing insulation against heat loss, a good roof system will have drainage. This allows a building to drain off excess water or moisture when the ground becomes wet from rain or snowfall. This drainage also helps to prevent roof leaks, which can damage the materials that are holding up the roof as well as the foundation of a structure. As such, roofing should be inspected periodically for any damage, especially if the water has leaked onto it. This type of damage can be repaired, but it is often more economical to simply replace the damaged materials with new ones.
Finally, roofing is used to protect the roof from the sun. This is most important in climates that have long periods of direct sunlight, such as southern United States and Florida, Canada, and Australia. The roof will be made out of either asphalt shingles or polyethylene tile, but not both. Polyethylene tiles are more commonly used for commercial buildings, but asphalt shingles are the more common choice for residential use.
