Lead Flashing in Cardiff
Where a chimney meets a slate roof in Roath, or a bay window meets the wall in Pontcanna, lead is doing the quiet work of keeping water out — and it's where a large share of Cardiff's roof leaks actually begin. On the city's Welsh slate and clay tile roofs, correctly dressed lead matters even more than on concrete tile roofs, since slate roofs typically use more intricate stepped flashings and valley details.
Lead flashing repairs in Cardiff address leaks at chimneys, valleys and bay windows on the city's Welsh slate roofs, where stepped leadwork is common. Re-dressing lifted flashing costs £150–£300, while a full chimney lead set typically runs £400–£900.
Roofing in Cardiff — what local roofers know
Across Cardiff Council's older neighbourhoods — Cathays, Splott and Grangetown among them — chimney stacks, valleys and bay windows set into Welsh slate roofs rely on lead flashing dressed into the mortar joints, and it's this detailing, not the slate itself, that most often fails first. The city carries a Moderate exposure rating rather than coastal-level battering, but named storms including Storm Eunice (2022) have still loosened flashings and ridges across postcodes such as CF5 and CF24, and older housing stock throughout the city — with original pitched roofs prone to worn valleys and perished underlay — is exactly where lifted or split lead tends to hide until a heavy rain event finds it. In conservation-conscious areas like Llandaff, matching leadwork detailing to the period of the property also matters for how the repair looks, not just how it performs.
