How to Choose the Right Metal Panels for Your Roof Slope: A Guide

If you are considering a new metal building, then one important decision you will need to take involves the roof pitch. With a range of roof styles, you can decide which type works for the area you live in and the slope of the roof pitch that will work for you. If you need some help to decide, then read our guide to choosing the right metal panels to suit your roof pitch needs.

What Do You Mean by Roof Pitch?

If you have heard the term ‘roof pitch’, but don’t know what it means, then it can be very stressful when you come to choose your steel panels. Put simply, roof pitch is the angle at which your roof rises, and it is essential that you know what it is so that you can choose the best steel panels for your building.

What Expression is Used to Explain Roof Pitch?

When you are expressing roof pitch, there are two ways you can do it. Firstly, you can express it in degrees, or you can choose to express it as ‘n/12’. When you are choosing a roof pitch for your steel building, your design team will be able to provide the degrees of the ‘n/12’ to help you understand the design.


Why Roof Pitch Matters So Much?

When you are installing metal buildings, it is important that you understand why roof pitch is so important. However, there are many answers to this question, so we have shared them below:

  • Rain – when it comes to thinking about the structure of your new build, it is essential that you consider how much rain you get in your area. Flat roofs are an attractive feature, but if your rain levels are high, then you can expect it to start leaking pretty quickly. Choosing a steeper roof pitch for your metal building is a sensible choice if you live in an area that experiences heavy snow, lots of rain, and other extreme weathers that threaten the structure of your building.
  • Local Regulations – areas that experience significant weather events are typically required to follow a strict building code to ensure safety and durability. Before you start building your new prefab metal building, it is imperative that you take the time to check out what the local zoning rules state and if your design will be able to get insurance.
  • Design Features – another important part of building a new metal building is the overall look and feel of the design. Roof shape and pitch play a huge part in the finished look, and it is important that you take the time to consider what will look the best as well as perform the best.
  • Pricing – cost is always an important consideration, and when you are choosing your new roof, you can expect different roof designs to use different amounts of materials and cost different amounts. Typically, a steep roof will cost more, leaving you to find the balance you need for your project.

Following Building Regulations with Your New Roof

Whether we like it or not, local building codes will dictate much of what you can and cannot do during your building installation. It is important to remember that different roof styles will have their own specifications to follow when installing. The 2012 International Building Code clearly sets out that your metal panels will need to follow these rules:

  • The minimal pitch allowed for steel buildings that are lapped and non-soldered is three vertical units in twelve horizontal units, providing a 25% slope.
  • The minimal pitch allowed for lapped prefab metal buildings with non-soldered seams that make use of lap sealant is one-half vertical unit in twelve horizontal units providing a 4% slope.
  • The minimal pitch allowed for steel buildings with a standing seam of roof systems is one-quarter vertical unit in 12 horizontal units providing a 2% slope.

The Minimum Requirements for Roof Pitch

It is important that you consider the minimum slope requirements depending on the profile of the roof you have. Your roof profile is the shape you get when your metal panels have been bent into shape. The slope of your metal roof can be expressed using a ratio that shows the vertical rise with the horizontal span. Some of the most common roof slope ratios are ½:12, ¼:12, and 3:12. When you work with Coast to Coast Carports, we will ensure that your chosen metal panels will work for your building.

The Uses of Low and Steep Sloped Roofs

When you are planning a new prefab building, there are many different uses that you may need it for. Understanding when to choose a low or steep roof is pretty straight forward:

  • Commercial Uses

If you are building a commercial building, then you will typically need a roof that is less than 3:12. These roofs offer a simpler design and a far easier to build, and cheaper to buy. These low-slope roofs are also easier to install on large metal buildings, making the project cheaper and more effective overall.

  • Residential Uses

When building a new house, you can expect a steep slope roof to be the preference and to come in steeper than 3:12. These roofs are great in areas that experience heavy rainfall and snow loads and also reduce the risk of water pooling and stagnating on the roof.
