Build A Pergola – Installing Purlins and Roof Sheets

As you build a pergola and get to the part where you install purlins and roof sheets then you know your pergola is almost complete.

Purlins are the timber boards that run parallel to the ridge and the final touches to the roofing framework. They provide support for the roof sheets.

Watch how Peter, one of our expert builders, deals with these as he builds a pergola. Link back to our earlier blog post on how to build a pergola for step-by-step instructions on how to install purlins and how to install roof sheets. Note that both the video and the instructions in the blog are for polycarbonate roof sheets.
