You don't have to replace the roof. You can coat it in a white, "elastomeric" paint like [1]. Each bucket can do about 450 sq ft (40 sq m) and is ~$100 for the supplies.
In California, roof color isn't regulated, but reflectivity (or rather energy absorption) is by Title 24. You're basically required on new construction to have a fairly efficient roof.

Then it's not your fault.
I'm talking people building or renovating and then bitching about expensive AC. Talk about idiotic.
I'm in a town where more than half the roofs are black. BLACK! It has been over 30 degrees and sunny for two months of summer. Guess what complaints I kept hearing?
Reflective paint helps in summer much more than it hurts in winter.
But beyond that, I just hate people going "Reeee we need to do something about the climate change" who do absolutely nothing themselves.

dark roof helps on cold days right?
I am one of your fuckees. The house I bought was expensive enough as it was. I am not changing a brand new dark roof for a different one for an exorbitant price right now, because budget. A perfectly new roof going down (isn't that actually waste?) for saving, say, 10 of 30 days when the AC is really needed?
(I am also not even sure if roof colors are regulated by the local authorities or not. There are over thirty houses in the same project, with the same roofs. Maybe I wouldn't even be allowed to.)
