Slate sizes have names
A Duchess is 24 by 12 inches, a Countess 20 by 10, a Ladies 16 by 8. We match the size your roof already has, so a repair blends into the roof.
Match the slate to the roof
Use the size guide below to recognise common slate names. We confirm the material and quantity after inspecting your roof.
Not sure which slate you have?
We identify the size and condition when we inspect the roof. You do not need to calculate materials before contacting us.
Tell us the property location, describe the problem and include a roof photograph in your email if you have one.
