A roof’s pitch refers to the level of incline in relation to the length of the roof. The higher the roof, the higher the slope of the structure. While most people use the terms “slope” and “pitch” in the same way. Slope actually refers to the angle of the roof covering whereas pitch pertains to the roof deck itself. However, since the slope of the roof is dependent on the pitch, the 2 terms refer to basically the same thing when the same roof is being talked about.
