A focused repair may suit when
- The defect is isolated
- Surrounding material is sound
- There is a clear water-entry cause
- Previous repairs have not repeatedly failed
- The remaining roof is serviceable
A broader scope may be considered when
- Defects occur across multiple areas
- Ridge work is widely deteriorated
- Old coatings are failing
- Many tiles or components need attention
- Ageing affects the roof as a whole
Paint is not leak repair
Coatings may form part of a suitable restoration system, but they should not replace repairs to broken tiles, flashings, valleys, fixings or structural defects.
