• Secure each panel: Use the appropriate hardware provided with your kit or structure to secure each roof panel in place. Make sure to follow the manufacturer’s instructions for proper installation.
• Seal the seams: Once all the roof panels are securely in place, seal any exposed seams or gaps with a high-quality sealant. This will help prevent water leakage and ensure the longevity of your gazebo or pergola.

By following these steps and taking the time to install the roof panels correctly, you’ll have a beautiful and functional gazebo or pergola that can enhance your outdoor space for years to come.

Attaching the Side Panels

Once the main frame of your 12×20 gazebo or pergola is assembled, it’s time to attach the side panels to enclose the structure and add privacy and protection from the elements. Follow these steps to securely attach the side panels:

1. Identify the side panels designated for each side of the gazebo or pergola. Ensure that you have the correct panels before proceeding with installation.

Consider adding intricate lattice panels, climbing plants, or decorative screens to give your structure a unique look. These additions can provide shade, privacy, and a touch of elegance to your outdoor space.

Decorative Element Ideas:

• Lattice Panels: Install lattice panels around the perimeter of your gazebo or pergola for a classic and decorative touch.
• Climbing Plants: Add climbing plants like vines or roses to soften the structure’s appearance and create a natural, lush setting.
• Decorative Screens: Incorporate decorative metal or wood screens to add flair and charm to your outdoor living space.

Applying Sealant for Weather Protection

One of the essential steps in protecting your gazebo or pergola 12×20 is applying sealant to guard against the elements. Sealant is a crucial component in weatherproofing your outdoor structure and prolonging its lifespan.
