Advantages of White Roof Coating
There are many benefits to white roof coating. For one thing, white roof coating absorbs less heat than dark roofs, meaning that homes with white roofs don’t need to rely as much on air conditioning during hot summer months. This can reduce cooling costs by up to 40 percent. In addition to saving you money on electric bills, white roof coating also protects the roof from deteriorating as a result of the sun’s powerful UV rays.
White roof coating is primarily recommended for flat or metal roofs, but switching to a white roof has the potential to actually reduce energy use by up to 20% in hot and sunny weather. In urban areas, white roofs also help lower smog levels by decreasing local temperatures, which tend to be higher due to the large proportion of paved surfaces. White roofs also, in fact, save on air conditioning use, which ordinarily emit about half a ton of carbon dioxide each year.
When it comes to colder weather, however, critics have suggested that white roofs actually do more harm than good. On the contrary, research shows that the heating benefits of a dark roof in the winter are essentially insignificant, as days are shorter and skies are cloudier. Additionally, the angle of the sun is lower, and of course, when it snows in the winter, roofs will become covered with snow. Therefore, white roofs are highly beneficial because they save energy and keep your house naturally cooler during those hot summer months.
