Colorado Springs Roofing: Article About How Roofing Reduces Heat Islands
A heat island is a common phenomenon throughout the developed world in which temperatures are typically higher in urban areas and lower in rural ones. Most modern construction methods make use of materials that absorb the sun's heat energy. For example, on a hot day, it may feel much warmer to stand on the sidewalk than in the middle of a city park. The materials that are used on roofs also contribute to this change in temperature throughout the urban environment.
For eco conscious homeowners, the consequences of this heat island effect are a serious issue. The good news is that residents can mitigate some of the effect by carefully attending to the building process. By working with reliable and experienced Colorado Springs roofing companies, homeowners can start to discover which roofing options are most appropriate for their home. Not only does the homeowner benefit their community by reducing heat islands, but they stand to enjoy a more comfortable home as well.
Essentially, heat islands occur when roofs and other materials absorb heat energy instead of reflecting it. Naturally, absorbing heat energy can be desirable in cold climates during the colder seasons. However, as temperatures rise, few homeowners want a home design that "bakes" them indoors.
A roofing contractor from Avalanche Roofing & Exteriors of Colorado Springs CO can answer any question about water damage restoration or attic insulation.
Therefore, the best roofs to combat the heat island effect have a high solar reflectance, or albedo.
With these environmental and energy saving goals in mind, roofing engineers have developed several options for use in residential roofing as well as other forms of construction. Cool roofs are designed to absorb less heat. According to the Environmental Protection Agency, these roofs are typically 50 to 60 degrees cooler than conventional roofs. They are most commonly installed on flat or low slope roofs, making them ideal for the construction styles of drier climates as well as many urban centers.
Aside from cool roofs, green roofs are another alternative that cuts down on the heat island phenomenon. Drawing inspiration from the cooler temperatures found within a city park, designers of green roofs borrow from Mother Nature's wisdom. Instead of man made materials, the roof is covered with plantings. These plants offer additional insulation and reduce the amount of heat absorbed through the roof.
Heat islands are primarily an issue for city or suburb dwellers. As climates shift throughout the world, many are finding cooler indoor temperatures desirable during hot summers. While it may seem that one roof makes a small difference in a whole city, the widespread adoption of cool roofs could go a long way. In addition, homeowners have reason to think about heat islands for their own benefit; a less absorbent roof means lower HVAC bills.
