A roof with x rise 12 run slope means that for every 12 inches horizontally run it rises x inches. The most commonly used roof pitches fall in a range between 4 12 and 9 12.

The basic ranges of pitch are not uniformly defined but range from flat which are not perfectly flat but sloped to drain water up to 1 2 12 to 2 12 1 in 24 to 1 in 6. This depends on who you are talking to. The average roof is 3 000 square feet or around 30 squares. Why is it more difficult roofing on steeper pitches.
