The colors used on the exterior side of the building envelope all have an impact on how efficiently the desired temperature can be maintained inside the building. As a general rule, darker colors absorb heat, while lighter hues reflect it, but here are some more details of how the rule applies for roofs.
In terms of contact with solar radiation, the roof is the most exposed housing component, in constant daytime contact with the sun’s rays. Black or dark colored roofs absorb the heat of the sun and transmit it towards the building interior, therefore dark shades are great for cold climate areas, where any help that can make the work of the heating system is welcome. Lighter colors, on the other hand, reflect solar heat, which means that they never become as hot as dark roofs and they make it easier to maintain the air inside the building cool.
The color of your roof can, in itself, reduce the strain that your air conditioner or your heating system has to endure in respective peak periods, but to be able to make the most of the thermal protection provided by your roof, it is a good idea add insulation underneath the roof as well.
