Roof Lining Repair for Older and Classic Cars

Roof linings in older cars are not always built like the ones in modern vehicles. Different eras used different constructions and materials, and that affects how a lining is repaired. If you own an older or classic car, here is what to know before you start.

Two main constructions

Board-type headliners

In a board-type lining, a rigid board is covered with foam and fabric and glued up against the roof. The board is commonly pressed fibreglass or fibreboard, and in some cars it is cardboard-based. Owners and restorers describe old boards as fragile. Heat tends to break down the foam backing first, as in a modern car, and the board itself can crack or warp when removed. Replacing the cover on a board-type lining is generally considered easier than working with the older bow style, as long as the board survives.

Bow-type headliners

In a bow-type lining, the fabric hangs from metal rods (bows) that slot into channels in the roof, and it is tensioned across them rather than glued to a board. This was common in older and classic vehicles. Restorers describe bow headliners as more labour-intensive, because the fabric has to be fitted and stretched correctly over the bows so that it stays taut without wrinkling or sagging. Replacement fabric for bow headliners is generally thicker to cope with the tensioning. Missing bows and fixing clips can often be replaced.

Some cars use both. For example, a sunroof model may use a board where a non-sunroof version uses bows.

Materials by era

Classic car parts suppliers note that the original materials depend on the period. A car from the 1950s may have used mohair cloth, while vinyl was common in the 1960s and 1970s. Many enthusiasts prefer like-for-like replacement to keep the car's character, but modern foam-backed fabrics are also widely used where originality is less important. Ask what is available for your model.

Why old linings fail

Heat and age break down the foam backing, so the fabric comes away from the board.
Moisture from leaks softens boards, especially cardboard-based ones.
Old glue becomes brittle or lets go.
Previous quick fixes, such as pins or tacks, leave holes and can damage the board.

Repair guides for classic cars advise against tacking a sag. Pins and tacks are temporary bandages that can look poor and damage the board underneath.

Considerations before restoring

Check the board or bows first. A fragile board may need careful handling or replacement.
Check for rust and leaks. Old cars often have seal failures, and a new lining will fail again if water gets in. See water stains and leaks.
Decide how original you want it. Match the original pattern and fabric type, or choose a modern alternative.
Take care with fittings. Dome lights, sun visors, grab handles and trim in older cars can be brittle or hard to replace.
Allow time. Older cars can hide surprises under the lining.
