How Dulwich's Local Conditions Affect Slate Roofs Over Time
Slate roofs beneath trees or beside tall neighbouring buildings can face different maintenance demands from open roof slopes. Debris, shading and wind exposure affect drainage and fixings even when the slate itself is durable.
Local conditions to assess
- Leaves collecting in valleys can redirect water beneath surrounding slates.
- Exposed verges and ridges need secure, suitable details.
- Persistent shade can make surface growth and drainage checks more important.
Inspection should consider the roof's position and details instead of assuming every Dulwich slate roof ages in the same way.
Retain sound material where practical
A slate inspection should distinguish the condition of the stone from that of its fixings, battens and underlay. Those components do not necessarily fail at the same time. Where renewal is proposed, ask whether suitable existing slates can be graded for reuse and how new units will match the retained roof. Include flashings and valley details in the scope.
