Purpose and function of the roof moulding

The left roof moulding for the BMW E81/E87 series is responsible for the aesthetic and functional finishing of the roof edge and the contact area with windows and seals. This component:

• masks mounting gaps and attachment points on the roof,
• stabilizes the body line in the upper part of the chassis,
• enables the maintenance of a consistent side profile design for the vehicle,
• complements other elements from the Doors and door panels group within the side body area.

Thanks to its factory profile, the moulding ensures proper adhesion to the roof and compatibility with original mounting points, which facilitates installation and reduces the need for additional modifications.

Color and visual fit

The finish in Black Sapphire Metallic - 475 allows for a consistent match with the factory BMW paint in this color. Metallic black blends well with both dark and lighter body colors, making the moulding suitable for use:

• as a component restoring the original look of the car after repair,
• as a replacement for a damaged or missing moulding on the left side,
• in projects where maintaining the factory roof styling line is essential.

The original paint color of the moulding reduces the need for additional painting, which shortens repair time and lowers vehicle preparation costs.

Vehicle placement and installation aspects

The moulding is designed for installation on the left side of the vehicle, in the upper part of the body, along the roof edge. Thanks to its factory profile and geometry:

• it fits the original mounting points in the roof,
• it maintains the correct line of adhesion to the body,
• it enables proper alignment with adjacent elements of the side body area.

The used OEM part is a good choice for repairs where maintaining original geometry and compatibility with BMW's factory design solutions is important.

Application in BMW body repairs

The left roof moulding in Black Sapphire Metallic is primarily used for:

• repairs after collisions involving the upper part of the side body area,
• removing the effects of corrosion or mechanical damage to the mouldings,
• completing missing elements during vehicle restoration.

Since it is an element from the Doors and door panels group, it fits well into comprehensive work on the side of the body, including the replacement of panels, doors, or other sheet metal components.
