Fixing the Pergola to Your Composite Decking

After preparing all you need to build your pergola, you can fix the pergola to your composite decking. 

Step One – Install the Posts of the Pergola

You must install the pergola posts and ensure that you fixed them firmly to the decking below. There are different types of composite patios. If your plastic wood decking is flushed and you installed it in the open space in your garden, your pergola will have four posts. But if you attach the pergola to your house, it will need two posts. This is possible if your composite decking is flushed with your home. 

To install the posts, you have to ensure you attach them to the frame or substructure of the decking and not the composite boards. Heavy wind can blow your pergola away if you connect it to the boards. Use your screws or nail to fix the posts to the composite decking. Depending on whether your decking is flushed or close to your house, you might have to tighten two or four pillars of the frame.

Step Two – Attach the Pergola Roof Frame

There are some premade pergola roof shades that homeowners can use. But if you prefer to bud your pergola style, you can attach the frame for the roof to the posts. For pergolas that are close to a house, you have to connect the roof frame to the wall of your home and screw it down. Attach planks to the posts until you have made the roof, but don’t cover the top of the pergola. Most pergolas have exposed roofs that homeowners cover when the sun is hot.
