Gable trim is installed at the gable ends to seal the edge of the roof, preventing water and debris from entering the roof system. It is often painted to match or complement the roof color or the home's exterior as it will overlap the metal roof panels at the gable ends.

Gable accent trim is an exterior decorative element applied at the apex of the gable, typically extending down and hanging from the rake trim. Gable accent trim is most commonly made from either wood, PVC, or fiber cement, and, when paired with a complimentary or high contrast rake trim, creates the final aesthetic edge of the roof.
