Do roof pitches have to match?
Unless you’re absolutely sure of the effect you’re after, avoid combining different roof pitches. More often than not, varied pitches look disorganized or, worse, like a construction error. Stick to a uniform pitch, and rely on the size and arrangement of roof masses for effect.

What is roof pitch? … For example a “3 pitch” or “3 in 12 pitch” or “3/12 pitch”, all mean that the roof rises 3 inches, for every 12 inches of it’s horizontal run. Using pitch, its footprint, and basic geometry, you can quickly and with a high degree of accuracy calculate the length of the gable sides.
