When you delve into the world of roofing, you’ll come across various terms and measurements. One of these is the roof pitch, often represented as a fraction like 8/12. But what does this fraction mean, and is an 8/12 pitch roof considered steep? In this blog, we’ll break down roof pitch, explain what an 8/12 pitch means, and discuss whether it’s steep or not.

Understanding Roof Pitch

Roof pitch is a crucial aspect of roofing design. It indicates the steepness or slope of a roof. Roof pitch is typically expressed as a fraction, with the first number representing the vertical rise, and the second number representing the horizontal run. For example, in an 8/12 pitch roof, for every 8 inches of vertical rise, there are 12 inches of horizontal run.

What Does 8/12 Pitch Mean?

Now that we know how to read roof pitch, let’s interpret what an 8/12 pitch roof signifies:

• The first number (8) represents the vertical rise, which is 8 inches.
• The second number (12) represents the horizontal run, which is 12 inches.

So, for an 8/12 pitch roof, there is an 8-inch vertical rise for every 12 inches of horizontal run.

Is an 8/12 Pitch Roof Steep?

Whether an 8/12 pitch roof is considered steep depends on various factors, including personal perspective and regional standards. Here’s a general guideline:

• Low Pitch: Roofs with pitches between 2/12 and 4/12 are considered low-pitched or low-slope roofs. These are relatively flat and are often found on modern homes.
• Moderate Pitch: Roofs with pitches between 4/12 and 8/12 are considered moderately pitched. They strike a balance between flat and steep and are common in many residential constructions.
• Steep Pitch: Roofs with pitches of 8/12 or higher are classified as steep-pitched roofs. These roofs have a steeper slope, which can have both functional and aesthetic advantages.

So, by general standards, an 8/12 pitch roof is considered steep. It has a significant vertical rise for every foot of horizontal run, making it steeper than the average residential roof.
