Maintenance
Routine maintenance of the membrane is not normally required, but regular inspection of the roof should be carried out at least annually and preferably in early spring and late autumn.
The purpose of this inspection is to:
- Check for damage
- Ensure rainwater outlets are not obstructed
- Check that materials from other trades have not been left on the roof
- Check lightning and fall arrest equipment
If ponding causes accumulation of silt or algae on exposed membranes, this can be removed by brushing when wet with a soft bristle brush and removed by water spray. Proprietary fungicides or cleaners are not necessary and may not be compatible with the waterproofing – they should not be used. It is recommended that a standard format roof plan, marked with co-ordinates, be used to record the findings of a planned inspection. This will avoid confusion with instructions to contractors and provide an ongoing record of roof performance, which can be compared year-on-year.
