Existing slate identified
We check size, thickness, colour and type before choosing the new unit.
Course alignment preserved
We fit the replacement to maintain the roof's overlap and appearance.
Repeat slipping investigated
We check whether nails, battens or wider ageing are causing movement.

Restore the slate course and its overlap
Each slate overlaps the rows below it to move rain down the roof. When one cracks, slips or disappears, that pattern is interrupted and the layers beneath become more exposed. We replace broken roof slates in Cardiff while preserving the alignment of the surrounding courses. Natural and manufactured slates differ in thickness, finish and fixing needs, so we first identify the existing covering. We then look for a replacement with a suitable size, colour and lap before removing the damaged slate and checking the course around it.
One slipped slate can reveal a deeper fault
A single impact break may call for a straightforward replacement. Repeated slippage is more telling. It can point to failing nails, weak battens or age-related deterioration across the roof rather than several unlucky slates. We assess the fixing area before securing the new unit with a suitable method. This protects the weatherproof pattern and avoids disturbing sound neighbouring material unnecessarily. If the same fault appears across several courses, we explain the need for a broader inspection instead of repeatedly replacing the latest slate to move.

Frequently asked questions
Can natural and manufactured slates be mixed?
They differ in thickness, finish and fixing requirements, so we first identify the existing roof covering. We choose a suitable replacement that maintains the course, overlap and practical weather protection.
Why do roof slates keep slipping?
Repeated movement can result from ageing or failed nails, weak battens or broader deterioration. We inspect the fixing area and surrounding course rather than treating every slipped slate as an isolated accident.
Will a replacement slate look exactly the same?
We consider size, thickness, colour and surface finish when selecting a replacement. Availability affects visual matching, especially on older roofs, but correct fit, lap and secure fixing come first.
