1. What color is your siding?
You want to complement your siding color with a contrasting roof color. If you have light-colored siding, you should choose a darker roof color.
A red house stands out with a black or gray roof. Dark gray, black, or green complements a light gray home. White houses are versatile and look great with any color roof.
You should coordinate colors with other color elements of your home. What color are your shutters? Your front door? You want to both complement and contrast colors. If everything matches, the overall look will lose its curb appeal.
A good rule of thumb is to match your siding color to your roof color by pairing a warm color with another warm color, or a cool color with another cool color.
