I'm getting a new roof on my house. I'm considering changing to brown

If anyone here has any experience about increased air conditioning costs
after going to a darker roof, I would like know how much your bill went up
(or didn't).

Particulars would be most helpful, such as climate, and how well the attic
was insulated.

My own particulars: Louisville KY, ranch house, low pitched hip roof,
poorly insulated attic. Air conditioner ducts do not pass through attic.
House gets a fair amount of shade from trees located on East, South, and
West sides. But they are Maples, and I don't want to assume they will last
the next 30 years.


IF (note the IF) the attic is insulated properly, the roof color will be
of no consequence. You will also be able to see the fungus on the north
side a lot more with the white than with the darker color. If your roof
does not have a north side, then disregard.
