Swarf Removal

Prevention of swarf damage is much easier than repair.

Dew or condensation will produce rust overnight, so the swarf should be collected as it is produced. A screw gun with a magnetic bit can be useful for this purpose.

As swarf particles are sharp, care should be taken not to damage the surface coating by wearing clean, soft-soled shoes that do not collect swarf, dirt, and gravel. Damage can be minimised by placing a mat or sacking at the base of the ladder so that shoes can be cleaned before moving on to the roof.

All contractors with access to the job should follow the same rules for cleaning up, work practices, and footwear as other trades are often responsible for causing damage that is incorrectly attributed to the roofing contractor.
