Roofs come in all shapes and slopes, and today, we’re demystifying the “10 pitch roof.” You don’t need to be an expert to get it. We’re going to keep it simple and clear, like chatting with a friend.

Understanding the 10 Pitch Roof:

Let’s dive in. A “10 pitch roof” is a way of saying how steep or flat your roof is. Forget the jargon; it’s just about the angle. So, what’s the deal with the “10”?

1. The “10” Breakdown:

Imagine a piece of paper – square or not. When you fold it diagonally, you get two triangles. Each of those triangles has a slope or “pitch” of 45 degrees. Now, the “10” part? It represents a 10/12 pitch.

2. Decoding the Fraction:

Clear as day, right? The “10/12” means that for every 12 inches (or one foot) of horizontal distance on your roof, it goes up by 10 inches. It’s like climbing a moderate hill – not too steep, but not a walk in the park either.

3. Simple Math:

Now, picture a roof that’s 20 feet wide. With a 10/12 pitch, for every foot of horizontal run, it rises by 10 inches vertically. So, for every 12 inches (or one foot) across, it goes up by 10 inches. If you do the math, that’s an 83.33% slope – steeper than most, but not extreme.

Why Does It Matter?

You might wonder, “Why should I care about my roof’s pitch?” Well, here’s the deal:

1. Efficient Water Shedding:

A steeper pitch helps water and snow flow off easily. It’s like having a water slide for raindrops, keeping your roof dry and trouble-free.

2. Aesthetic Influence:

The pitch can shape your home’s overall look. Certain styles, like Gothic, often feature steeper pitches for that classic, dramatic appeal.

3. Attic Possibilities:

A higher pitch can mean more usable space inside your attic. It’s like having an extra room up there for storage or a cozy nook.


In the roofing universe, a 10 pitch roof is like the adventurous choice – not for the faint of heart, but not extreme either. It’s practical for shedding water, and it can suit various home styles.

So, next time someone talks about a 10 pitch roof, you can nod knowingly. You’ve got it down! Remember, it’s all about that 10/12 slope, making your roof just right for your home.


As a civil engineer and roofer, I love to share the experience that I have gained through the last couple of years. In the roofing industry, practical experience is a very crucial fact that can help you a lot. Hence, I want to help you with my blog.
