Why Roof Leak
Detection is Essential
Roof leaks don’t just cause obvious water damage. When left unchecked, they can create a chain of costly and unsafe issues, including:
- Ceiling stains and sagging plaster.
- Mould and mildew (health risks).
- Electrical hazards in roof spaces.
- Costly structural damage if left untreated.
Signs You May Have a Roof Leak
- Water stains on ceilings or walls
- Peeling or bubbling paint near ceilings
- Damp smells or mould growth in roof space
- Dripping water during or after rain
- Sagging plasterboard
If you notice these signs, book a roof leak detection immediately.
