Today’s topic is “Pitches”. You may be wondering, “What kind of pitch?”. There are plenty of pitches we won’t be discussing today, like a baseball pitch, a sales pitch, or pitching a tent. Today we’re going talk about Roof Pitches!

Pitch is basically how steep your roof is. That’s about it. Thanks for reading! WAIT. We’re kidding. There’s plenty more to be discussed about Roof Pitches!

Roof pitch is commonly known as “slope” and is defined by how many inches the roof rises across 12 horizontal inches. This can affect both the form and function of your pole building.

Most standard size pole buildings look and perform best at 4/12 pitch. Remember when we said that slope was determined by how many inches the roof rises over 12 horizontal inches? 4/12 pitch means that the roof rises 4 inches for every 12 it runs. This is also known as “Rise Over Run” or “Rise/Run”.

Here’s a helpful graphic to show you exactly what we mean:

So, by this logic, 8/12 pitch means that it rises 8 inches for every 12 it runs. A higher pitch, like 8/12, allows snow and water to run off better than a low pitch does. The higher the number, the steeper the roof. The lower the number, the flatter the roof. Speaking of snow and water, roof trusses need to be designed and engineered to handle snow loads for the area they’re in. For example, if you’re in the middle of Minnesota or Upstate New York, you’re going to need your roof to handle a lot more snow than if you’re in Florida.

Another thing to consider about Roof Pitches is that some Homeowners’ Associations require the pitch of any other structure’s roof on your property to be the same as your house’s roof, or the roof of the primary residence on your property. We recommend that you call your local municipality to make sure you adhere to those restrictions.

In addition to changing the overall look of your pole building and handling snow loads, a higher roof pitch can also allow room for a second floor or attic space. If you want additional storage space upstairs, like an attic, you will need a steeper roof. If you’re looking for storage space or a smaller room, you’ll need at least 6/12 pitch or higher. If you want to be able to stand upright, and allow for walking room, we recommend 8/12 pitch or above.

In summation, Roof Pitches have a lot more to it than meets the eye. There are specific ways to measure roof pitch, certain qualifications a roof pitch needs to meet structurally in order to achieve certain things and looks aren’t just strictly that. You will need to do your due diligence in order to stay within your municipality’s requirements.
