Common Roof Pitch: Different Types of Roof Pitches Explained

Roof Pitch Explained

Roof pitch, also known as roof slope, is the measure of how steep a roof is. It typically expressed as a ratio or angle using two numbers separated by a colon. The first number is the vertical rise (inches) and the second number represents 12 inches of horizontal measurement.

Roof Pitch Explained

For example, a 4:12 slope means that for every 4 inches of vertical rise there are 12 inches of horizontal distance. Generally speaking, steeper roofs have higher pitches and flatter roofs have lower pitches with a 12:12 typically being the most common high-pitched roof.

Roofs with higher pitches (>6:12) tend to be more durable in areas prone to heavy snowfall since the weight of the snow can slide off easier than on roofs with lower slopes (<5:12). On the other hand, high-pitched roofs are best suited for regions with milder weather since they can still shed rainwater and have very little snowfall to worry about.

Roof Pitch Explained 6-12 Slope

The pitch of a roof is an important factor to consider when deciding on what type of material to use for the roofing job as well. Certain materials are better suited for certain pitches, so make sure you consult with a professional before making any final decisions. For instance, installing asphalt shingle roofing on a 1:12 roof pitch will fail.

Most Common Roof Pitch or Roof Slope (Residential)

Ever noticed how some houses have that just-right roof slope? Turns out, there’s a sweet spot most homes aim for—a 6/12 pitch. That means for every 12 inches the roof runs horizontally, it goes up by 6 inches. Why so popular? Well, it’s like the Goldilocks of roofs—not too flat, not too steep. It sheds snow like a champ, lets rain roll right off, and still leaves you some decent space in the attic to stash your holiday decorations.

But hey, it’s not a one-size-fits-all deal. You’ve got options from the laid-back 4/12 pitch to the mountain-ready 12/12. If you’re in a spot that barely knows what snow looks like, a chill 4/12 might do the trick. But if you’re living where winter means business, you might want to buddy up with something steeper.

Here’s the kicker though—no matter how steep or flat you go, if it’s not put together right, you’re gonna have a bad time. Proper installation is key to keeping the weather where it belongs—outside. And don’t skimp on materials. Whether you’re all about that metal look or traditional shingles are more your jam, picking quality stuff means not having to redo the whole thing when Mother Nature throws a tantrum.

How to Measure Roof Pitch or Roof Slope

Alright, let’s talk about getting to know your roof a bit better—specifically, figuring out its pitch. This isn’t just busy work; it’s crucial for when you’re looking to give your roof a makeover or build it from scratch. Knowing your roof’s pitch is like having the secret recipe. It tells you how much material you’ll need and which type of shingles or tiles will cozy up best with your home.

So, how do you crack this code? First up, you’ll need to measure the rise of your roof. That’s the distance from the top dog, the peak, right down to where it hits the wall, also known as the eaves. Got it? Great.

Next, we’re measuring the run. This is the width of your roof at the base – basically, how long it stretches out for. Now, here comes the math part (don’t worry, it’s not too scary). You take your rise measurement and divide it by your run. This gives you your pitch, revealing just how steep your roof is.

Benefits of a Higher Roof Slope

Installing Asphalt Shingle Roofing Requires More Slope Than Metal Roofing

Dipping into the world of roofing, did you know there’s a minimum slope needed to roll out those asphalt shingles? Yep, we’re talking a 2:12 pitch—meaning for every 12 inches that roof stretches out, it needs to rise by at least two inches. Now, if your roof’s got a gentler slope than that, don’t fret. There are workarounds like adding extra flashing or opting for shingles specially made for low-slope roofs to keep water from throwing a pool party up there.

But here’s the catch: stick to the script. Manufacturers have their rulebook for a reason, and straying from it could mean waving goodbye to your warranty. Especially since many won’t honor it if your roof’s slope is playing it too cool with less than that 2:12 pitch. My advice? Before you dive in, have a chat with a roofing professional. They’ve got the scoop on how to keep your roof tight and right.

Switching gears to metal roofing, it’s a bit more forgiving with the whole slope situation. Most metal roofs are happy as long as there’s a 1:12 pitch. But hold onto your hats, because some metal options are cool with even less—down to a .5:12 pitch, practically flirting with being flat. Speaking of flat, ever seen those tar and gravel roofs? They’re basically the chillaxed cousins in the roofing family, lounging around with a mere 1/2-inch rise per foot. So, whether you’re going steep or keeping it sleek, there’s a roofing material ready to match your style. Just remember, playing by the rules makes for a happy roof.
