I don’t know for sure but I assume of it is because light roofs require more maintenance to look as nice. Nothing shows up on a dark brown or black roof. A white or light grey would show dirt and debris. I don’t want to waste my time washing my roof because my HOA doesn’t like the way it looks.

i guess so? But a dark grey roof is already literally made from asphalt. It can’t look much worse that proto road material.
Even then you could easily do a brighter grey color. Doesn’t have to be white, but nearly every roof i ever see is either black, some variant of a dark color. Not a lighter grey or red, those are lot less common.

Also, the color doesn’t make that much of a difference. Like a percentage you can count on one hand. Much more significant gains can be had from ridge vents and other ways of getting the heat out of the attic, and insulation to keep that heat from going into the house.
At least according to my acquaintance in the roofing industry, and obvs this is regarding typical US/Canada SFHs

i could see the utility in it providing natural drafting for ventilation, but honestly, with the advent of modern homes moving towards insulated attics and loft spaces, that’s definitely the correct choice.

It’s cause they are built from petroleum
