How to Build and Install Metal Trusses in 4 Steps

Roof trusses are the backbone of your roof, giving it structure, shape, and durability. When it comes to selecting the right material, metal roof trusses are one option some homeowners choose for projects like sheds, garages, and pole barns. While the cost of metal trusses is nearly double that of wood trusses, metal can bear a higher load than wood. This means if you are planning a bigger structure like a large livestock barn, you can have a wider span with more space in between supports. Below, you’ll find the steps you need to take on this project.

Before Starting to Build and Install Metal Trusses

Trusses form the framework for your roof, giving it shape and support. Unless you are an experienced roofer or builder, this probably isn’t a DIY project for the weekend. Roof trusses impact the function of your roof, so any mistakes could result in significant (and costly) problems down the road. Not to mention, the necessary know-how needed for successful and safe welding. If you have a solid understanding of how the parts of a roof fit together and a background in building, the steps below outline what's involved in building metal trusses.

How Much Does It Cost to Build Metal Trusses Yourself vs. Hire a Pro?

You may be looking at all of these steps and thinking it’s best to hire someone to take it off of your hands instead. Here’s some additional information to help you make the best decision for your home project.

DIY Truss-Building

Roofing labor costs about $50 to $75 per hour, so by building metal trusses yourself, you’ll likely save on that cost. However, this project is not an easy DIY, and you’ll need to research the following to ensure the project is done safely and correctly:

• Acquire all necessary permits

• Purchase safety gear like gloves, safety glasses, a hard hat, and a welding mask

• Ensure that you perform the work in mild weather, not during rain, snow, or high winds

Hiring a Roofing Pro

Hiring a local metal roof contractor is a much safer bet. While it might save you money on labor in the short term to try to build metal trusses yourself, it will probably actually save you more in the long run if you hire a pro. That way, you won’t be paying for roof repairs later or the cost of a replacement roof due to any mistakes made in the building process.

Plus, doing this job yourself may void your roof’s manufacturer’s warranty, meaning you’ll face high costs if your roof gets damaged in the future.
