What this means in practice
Chimneys, valleys, abutments, ridges, verges and eaves are where different materials and movements meet. Repairs must address the supporting masonry or timber as well as the visible lead, mortar, plastic or metal finish.
What to check next
- Compatibility with ridge and roof covering matters
- Follow fixing centres and manufacturer instructions
- Mortared remnants should not obstruct the system
When should you ask a roofer to inspect it?
Arrange close inspection for loose masonry, repeated staining around a chimney, split lead, detached verge units or gutters that still overflow after cleaning. Scaffold-dependent repairs should be grouped where sensible so access is not paid for twice.
Safety first: do not climb onto a roof without suitable access, training and protection. Keep clear of loose coverings, unstable ceilings and water near electrical fittings.
