Not with all the brown you have.

So, do you suggest going with the similar brown color?

You might be able to go with a color that spans the brown greyish color tone.

This would be a more traditional look.

See how bad adding gray to all the brown looks? It's not a good outcome. The brick is going to keep to tied to something in the brownish family for the roof.

Take advantage of the online tools they offer so you can see the roof on your house.

Tudor Revival homes often had slate roofs. Or wood shake roofs. So roofs that emulate slate or wood tones should work well on your home.

I think a dark brown is best on your home. The picture of the applachian sky above is a nice color. I dont really like the shaded colors on your house. They look a bit busy. I would look for shingles that are all the same color, similar to what you already have.

Look at photos of old tutors and follow suit! do not do gray.
