Metal Roofing Colors Cool Roofs

All bridger steel 29 gauge colors are cool roof certified except for black galvalume and galvanized.

Metal roofing colors cool roofs.

Historically cool roofs have been either white or some other lighter shade color. Light metal roofing colors such as. These light colors are often referred to as cool metal roofing colors. Cool metal roofs can help reduce energy consumption by lowering cooling loads with their wide array of finishes designs and colors.

Cool roof performance is a function of two radiative properties. A cool metal roof with high solar reflectance and high thermal emittance would have a lower surface temperature as compared to a roof with low reflectance and low emittance. Since more heat is reflected energy bills are lowered. Cool painted metal roofs retain 95 of their initial reflectance and emittance over time equaling longer lifespan over conventional roofing systems.

White beige bronze sand light blue etc reflect the sun s rays a lot better than darker ones thus keeping your home cooler in the summer. While a metal roof is already more energy efficient than asphalt shingles you can maximize its efficiency by choosing the right color. Solar reflectance is defined by the cool roof rating council crrc as the ratio of the reflected flux to the incident flux. Look for the solar reflectance index metal roofing number on our color charts to find a cool roof color for your next roofing project.

Cool roof coatings are white or special reflective pigments that reflect sunlight. Metal roofing utilizing cool colors are known to have energy savings ranging from 7 15 of overall cooling costs. In the case of a cool metal roof a lower surface temperature translates into less heat gain into the attic space or living space below the roof. You should go with a lighter color metal roof such as lighter shades of green silver or off white if you want to attain maximum energy efficiency and keep your home as cool as possible during summer.

However you can also go with other colors such as red or even black as long as it s a cool roof rated color. And with metal roofing panels while to the eye a cool brown and a standard brown may appear almost the same color the cool brown is almost 20 percent more solar reflective than the conventional brown 27 percent versus 8 percent. Compared to dark colors light colors such as white light bronze beige and peach are better at reflecting the sun s heat rather than absorbing it into the building. In other words the number reported for solar reflectance for a roof product is a decimal number less than one that represents.

You can usually make a new or existing roof cool by selecting the appropriate surface. 26 gauge color chart. Solar reflectance and infrared emittance. 29 gauge color chart.
