Roof lingo can be as puzzling as a complex puzzle, but today, we’re breaking it down to basics. Let’s unravel the mystery behind a “5 pitch roof.” Think of it as a roofing 101 lesson, simple and straightforward.

Understanding the 5 Pitch Roof:

No more head-scratching, let’s get right to it. A “5 pitch roof” is just a fancy way of describing how steep or flat your roof is. We use numbers to do this, and in this case, it’s all about that magical number 5.

1. What’s the “5” All About?

Imagine a piece of paper again, but this time, it’s a square. If you fold it diagonally once, you get two triangles. Each of these triangles has a slope or “pitch” of 45 degrees. Now, let’s move on to the “5” – it stands for a 5/12 pitch.

2. Let’s Break Down the Fraction:

Got it? Good. The “5/12” tells us that for every 12 inches (or one foot) of horizontal distance along your roof, it goes up or slopes up by 5 inches. It’s like climbing a small hill – not too steep, but not flat either.

3. Easy Math Alert:

Now, think about a roof that’s 20 feet wide. With a 5/12 pitch, for every foot of horizontal run, it goes up 5 inches vertically. So, for every 12 inches (or one foot) across, it rises by 5 inches. If you do the math, that’s a 41.67% slope – still not too steep, right?

Why Does It Matter?

You might be wondering, “Why should I care about the pitch of my roof?” Well, here are a few good reasons:

1. Rain and Snow Runoff:

A steeper pitch helps water and snow slide off smoothly. Think of it as a slippery slide for raindrops and snowflakes, keeping your roof watertight.

2. Aesthetics:

The pitch can influence the overall look of your home. Some architectural styles, like Colonial, often feature steeper pitches for that timeless appeal.

3. Attic Space:

A lower pitch can mean more usable space inside your attic. It’s like having extra storage or a cozy hideaway under your roof.


In the roofing world, a 5 pitch roof is like a middle-ground option – not too flat, not too steep. It’s practical for shedding water, and it can suit various home styles.

So, the next time someone talks about a 5 pitch roof, you can nod with confidence. You’ve cracked the code! Remember, it’s all about that 5/12 slope, making your roof just right for your home.
