– Cut the panels to fit around vents, chimneys, and other roof features using a saw.
– Apply flashing and sealing tape to seal the edges and joints of the panels.
6. Final Touches
After installing the metal roofing panels, it’s time to add the final touches:
– Inspect the roof for any gaps, loose nails, or improperly installed panels.
