Definition
Roof pitch simply refers to the slope, angle, and slant of your roof. A roof’s pitch is represented as either two numbers divided by a slash, or as a ratio with a colon between two numbers. The first number is the numerator, and the second number is the denominator. Each number represents a specific measurement of a roof’s slope. The numerator represents the vertical height of a roof’s slant, while the dominator represents the horizontal length of a roof’s slant.
These numeric values vary a great deal depending on the construction and architecture of a home or property. There are flat roof systems with little to no slope, as well as, low-pitched roofing company akron systems and high-pitched roofing systems. On average, most systems range in pitch from 4/12 to 8/12. Flat systems may have extremely low values, such as ¼ over 12, while other high-pitched systems may have a 12/12 value and slope down at a perfect 45 degree angle.
Doing the Math
The math can be tricky since the number 12 is the common numeric value used for slope denominators. Even though 12:12 can be reduced to 1:1, the number 12 is always used for roof pitch purposes. To read a roof pitch value, you would need to start with the top number (numerator) and finish with the bottom number (denominator).
