Secure the drip edge using screws spaced no more than 24 inches apart. Ensure screws are driven through the drip edge and into the patio's framing members for maximum durability.

Installing the Metal Roofing Panels

For the following rows, use a trim piece or panel to cover the overlap and give a clean, professional look. Continue this process until the entire patio is covered, ensuring each panel is properly aligned and overlapped.

Securing Flashing and Ridge Caps

Once the main roof panels are in place, install flashing around protrusions like chimneys, vents, and skylights to prevent water intrusion. Use a combination of flashing pieces andcounter flashing to create a watertight seal.
