A Step-by-Step Guide to Installing a Slate Roof
Installing slate is a coordinated roofing project involving the structure, underlay, battens, fixings and weathering details. Getting the layout right before laying slates prevents awkward junctions and avoidable cuts. This guide describes what homeowners should expect from a professional installation.
The main installation stages
- Survey the roof, agree the slate specification and establish safe access.
- Repair the supporting structure and specify underlay, ventilation and battens.
- Set out and fix the slates to the selected product and site requirements.
- Complete ridges, verges, valleys, flashings and rainwater details before inspection.
Ask for the final specification and completion photographs, particularly for details that become concealed.
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.
