A Guide to Calculating Roof Pitch
What roof pitch is, and the math behind it, are actually quite simple, but you might feel yourself getting a little confused while trying to understand what it means and how it impacts your new building. By the end of this post, you’ll know how to quickly calculate it, and you’ll also know why it is so important for the overall success of any structure.

Calculating Roof Pitch
At the heart of the idea of roof pitch is the comparison of “rise” over “run”. In roof parlance, the “rise” is how much the roof rises vertically, while the “run” is the distance that it travels horizontally. Comparing these two numbers is how you can determine the pitch of a roof. For simplicity’s sake, the pitch is usually represented by how much rise a roof has for every 12 inches of run.
So, for a quick example, if you measure that the roof has 3’’ of vertical rise for every 12’’ of run, you could say that the roof pitch is 3:12. That is just the shorthand way to demonstrate the 3’’ of vertical gain for each foot of horizontal travel. While there isn’t necessarily a “standard” roof pitch – this number varies wildly from one roof to another – something in the range of 3:12 or 4:12 is pretty common.
How Roof Pitch Impacts Building Maintenance
More important than knowing how to calculate the pitch of your roof is knowing what that pitch means for the performance of the roof, so you can select the right option for your needs. As you might imagine, a steep roof is going to be very efficient in terms of shedding rain and snow, but if it is going to be on top of a large building, it will have to be very tall to make the geometry work. So, for a bigger building that isn’t going to be in place that deals with a lot of snow, you might want to consider a slightly flatter pitch.
There is also an element of aesthetics to consider on this matter. If you go with a steep roof pitch, a large portion of that roof is going to be visible to people standing at ground level. That’s neither a good or a bad thing, but it is something to remember and think about. You can effectively hide some of the roof by opting for a flatter pitch, but you shouldn’t let cosmetic considerations get in the way of what will function best – concern yourself mostly with function first, and then factor in aesthetics at the end to make sure you love the finished product.
Materials Best for Roofs
Choosing the best materials for your roof and your building as a whole will make your upcoming project more successful. Of course, as we specialize in metal buildings, that is exactly what we are going to suggest for a variety of reasons. As a starting point, metal buildings are less expensive than wooden structures. But that doesn’t mean lower quality – that’s not the case at all. Metal buildings, when purchased from a trusted supplier, are extremely reliable and will be an asset to your property for years to come.
It’s also nice to know that when you go with metal, you’ll have a lighter overall roof than a wood building. This makes engineering metal buildings a more flexible experience, as without so much weight within the roof to consider, it’s easier to adopt different designs and still have them fall within safe limits.
Build a Custom Metal Building
Roof pitch is an important concept in the building world, but it doesn’t have to be a point of confusion as you plan out your next project. When adding a new metal building to your property, partnering with the right company is crucial. Carport Kingdom is the ideal choice.
