First, there needs to be what I call ‘water forensics, roof assessment or investigation’.
- Water can track a considerable distance from the original point of entry.
- This needs to be determined prior to works starting.
- Using a concrete roof as an example - water may track underneath the existing failed sheet membrane and find its way out to rooms below.
- Inevitably the entire rooftop may require a newly installed robust membrane - not just the area of water leaks.
