How to build a pergola roof

Person screwing shade batten into pergola roof.

Overview

You can choose from a range of different shade types for your pergola. Here you'll see how to install shade battens. You can use these to cover as much or as little of the pergola as you like.

Steps

1Screw in the shade battens

Install your first batten so that it lines up with the edge of your pergola. Pre-drill the batten with your driver and then screw the batten to every rafter of the pergola. Use a spacer to show you where your next batten should go before you screw it down. This will make sure you'll always have a consistent gap.

2Measure and cut the ends for a straight finish

Now you're ready to cut the rafter ends off so they are all the same length. Choose the line you want outside the final rafter. Then clamp a spirit level down to give you a neat, straight cut. Use the circular saw to carefully cut the battens and you're done. 

Health & Safety

Asbestos, lead-based paints and copper chromium arsenic (CCA) treated timber are health hazards you need to look out for when renovating older homes. These substances can easily be disturbed when renovating and exposure to them can cause a range of life-threatening diseases and conditions including cancer. For information on the dangers of asbestos, lead-based paint and CCA treated timber and tips for dealing with these materials contact your local council's Environmental Health Officer or visit our Health & Safety page.

When following our advice in our D.I.Y. videos, make sure you use all equipment, including PPE, safely by following the manufacturer’s instructions. Check that the equipment is suitable for the task and that PPE fits properly. If you are unsure, hire an expert to do the job or talk to a Bunnings Team Member.
