If I run Google search for "roof" the pictures are typically of medium or dark gray, medium or dark green, medium or dark brown, brick red and other not very light colors - very rare are clay or sand coloured or similar colours roofs.
Neat image from Wikipedia:
Roofing materials nowadays are typically engineered (plastic coated steel, etc), not natural materials such as straw, and can have whatever color you please.
It looks like light coloured roofs absorb much less sunlight and so heat up notably less and this should prolong their lifetime. In my experience the key reason of dark ruberoid degradation is evaporation of resin because of sun radiation - it loses elasticity, basically turns into cardboard and then inevitably tears into pieces. I assume similar degradation processes happen in all materials that are either coated in plastic or rely on elastic resin for their properties.
Why are lighter coloured roofs not more popular? Is there any engineering reasoning behind this, or is it simply a design aesthetics choice? Does a light color roof provide any significant benefit from durability standpoint?
