A beam is required for added support, and this will need 200×50 (2×8) lumber. You'll need two pieces at 4.5m (15ft) long, totaling 9m (30ft) of lumber.

For the finishing touches, you'll need 150×25 (1×6) fascia board for the front and side barge boards. You'll need 18m (60ft) of lumber for this.

It's essential to follow the construction details carefully to ensure a sturdy and safe frame.

The beam is a crucial element in constructing a lean-to pergola, and it's essential to get it right. Check out the top of each post for the beam by marking a horizontal line 200mm (8″) down from the top outside edge of each post.

Cut along the pencil mark with a power saw to a depth of 50mm (2″), which is the thickness of the beam. Do this to all posts.

To create a strong and stable beam, scribe a line 50mm (2″) in from the outside edge of each post from the top, down 200mm (8″). Cut down that line using a sharp handsaw.

Bolt the 200×50 (2×8) beam to the posts using m12 (1/2″) galvanized bolts and washers. Ensure all posts are plumb (vertical) and parallel, as this will provide a solid foundation for your lean-to pergola.

Here's a quick rundown of the steps to follow:

Fixing a roof is a crucial step in the construction process, and it's essential to get it right. To fix a ledger plate to the fascia board, mark a level line just below the spouting and use a spirit level or a water level to ensure it's perfectly horizontal.

You'll need to fix the ledger plate to the level line on the fascia board using coach screws at least every 1200mm (48″) apart, making sure they penetrate through the fascia board and into solid timber, usually the end of a roof rafter or eaves sprocket.

For fixing PVC or polycarbonate roof sheets, you'll need to use the right type of screws, which are readily available from suppliers. If you're choosing between different types of screws, hexagonal heads are the easiest to use.

To fix the roof sheets, you should aim to fix them at every fourth corrugation, unless you're at a gutter, ridge, or overlap, where you should fix them at every second corrugation. This will ensure a secure and even finish.

When building or renovating a structure, the roof pitch is a crucial factor to consider. Most types of PVC or polycarbonate manufacturers recommend a 10-degree pitch, which is roughly equivalent to a 1 in 5.7 fall.

This pitch is often considered the standard for these materials, and it's not hard to see why. A lesser pitch might require additional weatherproofing measures, such as extra flashings or appropriate sealants.
