Most Reflective Metal Roof Color

White and light colors.

Most reflective metal roof color.

It is best to choose a light color metal such as white light bronze beige peach light green or blue if you live in a region that has a lot of sun and a hotter climate. The reality of color selection is that the color choice is only part of the decision that is being made. Such a roof can be reasonably expected to be some 50 to 60 degrees cooler than a dark color asphalt shingles roof. Do colored metal roofs absorb or reflect heat.

Compared to a white metal roof that reflects and releases up to 59 of the sun s heat white being the most energy efficient a galvalume roof only reflects and releases 25 of the sun s heat. Slightly darker and muted shades that tend toward the blue side of the color spectrum are called cool. Most to all other modern metal roofs have color applied in a factory setting. A white or light colored metal surface reflects best under testing at about 67 percent reflectivity and even some newly developed cool colors send the rays away source.

These colors will inevitably fade to a different hue of the same color. Step 1 heat reduction. If you are looking to reduce the heat in the building or structure which has the metal roofing you are looking to paint then this may be the paint for you and your needs. White is the most reflective color and white metal roofing can actually lower the ambient.

Modern energy efficient metal roofing acts as a giant mirror of sorts by reflecting the heat and energy up into the air. This means it can reduce the temperature inside the structure as much as 50 degrees in some conditions. Despite galvalume being very reflective it lacks the ability to release stored heat back into the atmosphere once it heats up.
