Roofing

Color descriptors are strange things. Someone who is blue is sad, not cerulean. Seeing red has nothing to do with a primary color; you are just angry. A green roof is not green. It means it is environmentally sound, harmonizing with the goals of lowering our carbon footprint and increasing energy savings. Your San Antonio business baking under the southern sun can tap into the power of a green roof to lower your energy costs.

Color and Temperature Basics

The sun’s light is a mix of three wavelengths:

  • Ultraviolet light—Energetic but invisible light
  • Visible light—Red, orange, yellow, green, blue and violet give us all the colors of our world
  • Infrared—Heat energy

Your Texas business stands bravely under the ultraviolet light (which breaks down molecules in the roofing material chemicals) and bakes beneath the infrared energy, which heats up your building. 

Lighter colors reflect the sun’s energy, while darker colors absorb that energy. This reflectance sends infrared rays back into the atmosphere, rather than letting them soak into your structure. High-emissivity coatings also radiate infrared energy back into the atmosphere quickly, while low-emissivity products trap heat in your building, raising internal temperatures. 

Think of Mediterranean villages, with sparkling white roofs beside azure seas. The homes stay cooler because the roofs stay whiter. 

Cool Roofing

Green roofing, then, can be brilliant white and save you a lot of money. The U.S. Environmental Protection Agency (EPA) reports that cool roofs make good economic sense for businesses, especially in the sun belt. 

Six Benefits

The EPA and U.S. Department of Energy point to six energy-saving benefits of a cool or green roof:

  1. It reduces energy bills by decreasing air conditioning load
  2. It improves indoor comfort in spaces for which air conditioning is not economically feasible, such as warehouses and factory floors
  3. It lowers peak energy demand, preventing localized power outages and keeping businesses productive
  4. Lower demand preserves nonrenewable resources, keeping commodity prices lower and electricity rates down
  5. Reduced power plant emissions mean smaller quantities of carbon dioxide, sulfur dioxide, nitrous oxides and mercury in our air
  6. Lower roof temperature on a green roof extends its service life, saving costs on removing the old roof and installing a new one
