Roof

The roof is your standard roof material, available as OEM or alternative suppliers, if maintained correctly will last a long time. They are typical lined with rubber in the centre, making them waterproof.

Maintenance

See Roof

Water Leaks

If you find water leaking above the steering wheel, check the drainage channels are not blocked. This can be found under the 2 metal plates on either side of the rollbar, held down by 2 screws. A buildup of dirt over the years will force water under the roof seal.

Water gets between the roof and the header rail, it needs to be able to drain through the windscreen pillar, otherwise air pressure will drive it past the rubber seal into the car. Too much sealant when replacing the windscreen can block the channels.

Remove the plate and unblock using some soft thin bendable wire, then test by slowly pouring water down the channels, it should reappear by your feet under the car.

Elbow

The area around the V shape of the frame, above the door button is a weak point and tends to weaken over time from constant flexing, this will slowly shred and wear, leaving you no option but to repair or start budgeting for a new roof.

Frame

The roof frame is rigid and not susceptible to failure apart from the frame bolts, which can shear and break off. Called a Pivot bolt, they are not available to buy separately but a precision engineering firm can replicate these.

Rear Screen

Use the BMW toothpaste cleaner to improve appearance and remove scratches. If replacing, reinforce the inside of that area.
