Installing Roof Trusses: 5 Mistakes to Avoid

Latest News

Installing timber roof trusses is a topic we hear about a lot as timber roof truss manufacturers. Although we are involved in the design, manufacture, and delivery stages of a house build (the installation is up to you) we have definitely seen our fair share of mistakes when installing roof trusses. Here are 5 mistakes to avoid when installing roof trusses.

Should you install roof trusses?

When you choose an engineered roof system, like the timber roof trusses we make, one of the many benefits is that they’re relatively quick to install. We’ve already done a great deal of the hard work for you. But, it’s important to remember that it’s not fool proof! Whilst we’re confident our trusses are great quality, they can only ever be as good as the installation job – and that’s out of our hands!

Mistakes during installation can be costly, at the very least. In the worst cases, it can spell disaster for your building project. So, we’ve collated a few of the most common roof truss installation mistakes, so you can avoid them!

1) Making changes to the foundations

If the roof trusses have been made to a plan, and you subsequently make changes, even at foundation level, don’t forget about your roof. Any deviations from the original plan will lead to problems with installing the roof trusses.

2) Supplying incorrect measurements

This is a very common problem. Some roof truss manufacturers will produce your order based on your supplied measurements. If you supply the incorrect measurements, the roof won’t fit – simple as that! Getting the measurements right is also critical for load bearing, so it’s a really important part of the process.

If you’re in East Anglia, the good news is that you can give us a call and we’ll come and measure up for you. We’ve measured up for hundreds of roof truss projects, so we know just what to look out for. It also passes the responsibility for getting this bit right from you to us. If there is an error in the measuring, it’ll be up to us to put it right!

3) Incorrect bracing for the project

Outside walls must be lined and braced off well before you attempt installation. Once trusses are loaded, moving walls is very difficult. You can take a look at some of our previous projects here and learn more about the kinds of projects that require installing roof trusses.

4) Using the wrong size connector plates

It’s important to make sure you get the right size and weight connector plates for your roof. If they’re too small they might not hold the trusses together under the weight of the roof. Too large and the structure may not fit.

We’ve thought of that too! If you order through us, we’ll supply all the connector plates and other hardware that you need to complete installation successfully.

5) Failing to follow the plans

Each piece of the roof has its place. There’s little room for error. If you load the packages incorrectly, put things in the wrong place, or spin them backwards, it won’t work! Make sure you follow the plans carefully to save yourself a lot of time and heartache.

And a final word on safety. By their very nature, when you’re installing roof trusses, you’re likely to be working at height. Do not take any risks. Make sure you work on a dry day, wear safety gloves, helmet and protective clothing.

It’s our mission to make your life as easy as possible. If you’re in Norfolk, Suffolk or Cambridgeshire, choose us and you’ll immediately knock a couple of these potential mistakes off your list of things to worry about. Why not give us a call to discuss your project?
