Slate is one of the longest-lasting roofing materials available, prized for its natural beauty and exceptional durability. Many slate roofs remain in service for generations, offering a timeless look that few other roofing materials can match.
Even slate isn’t immune to weathering, though. Tiles can develop hairline fractures, become porous, or shift out of place over time, and the flashing details around chimneys and valleys are often the first point of failure. Addressing these vulnerable points before they lead to leaks helps protect both the roof and the structure underneath, without compromising the character of the slate.
Our Slate Roof Coating Process
Roof Inspection
We carry out a detailed inspection of tiles, flashings, valleys, and fixing points, identifying cracked, porous, or displaced slates as well as any deteriorating metalwork around chimneys and valleys.
Cleaning and Preparation
The roof is cleaned to remove moss, lichen, and surface debris using methods that avoid dislodging or damaging the slate tiles during the process.
Repairs
Any loose, cracked, or displaced slates are re-secured or replaced first, so the roof structure is sound and complete before targeted coating work begins.
Priming
Porous tiles and vulnerable flashing details are primed individually to prepare these high-risk areas for coating.
Membrane Coating Application
The liquid membrane coating is applied to seal and reinforce cracked tiles, flashings, and valleys, stopping water ingress at its most common entry points while preserving the natural, traditional appearance of the slate.
