How Roof Pitch will Determine the Materials Used

When choosing the roofing material you want for your home, there are a seemingly infinite number of choices. However, the pitch of your roof is a significant factor in which materials will work. The roof pitch is the angle, slope, or slant of your roof. The roof pitch designations are usually portrayed as a fraction, with the numerator noting the height and the denominator indicating the length.

How Do I Calculate Roof Pitch?

Let’s say the pitch of your roof is 5/12. That would mean that for every 12 feet in length, the roof height rises 5 feet. The average roof pitch ranges from 4/12 to 8/12. On the more extreme end, a nearly flat roof would be in the 1/4 – 0/12 and a perfect 45-degree angle would be 12/12.

What Materials Work Best for Which Pitch Ranges?

1/12 to 3/12 Pitches: Lower roof pitches are commonly found in urban and contemporary-style homes. You cannot have shingles on these types of roofs, as the water will not drain off fast enough due to the lack of slope in shape. Built-up roofing made from tar paper roll or a standing seam metal roof is your best bet for a watertight seal.

4/12 to 12/12 Pitches: Asphalt and composite shingles are great options for these pitches. The slope is steep enough to allow for proper water runoff.
