Chimney Flashing Repairs

Useful observations include water marks on a ceiling or wall near the chimney breast, dampness after wind-driven rain, cracked sealant, old temporary patches, loose adjacent tiles, weathered mortar or visible gaps around the junction. Record whether the concern changes after particular weather and whether the stain is new, recurring or growing.

The brickwork, chimney, roof covering, flashing, mortar and nearby tiles form a group of connected details. Water can travel before it becomes visible, so an indoor mark may not sit directly beneath the point of entry. We inspect old sealant, patches and adjoining materials to identify the junction repairs required.

We inspect the chimney flashing, adjacent tiles, mortar and roof connections on site. Where signs extend beyond the chimney, we include the connected roof area in the leak investigation and explain any further access needed.

We identify whether the affected flashing can be repaired or needs renewal, then explain the compatible materials and preparation proposed. The repair plan follows the junction condition and any adjoining roof defects found on site. On a completed chimney flashing project, our work included waterproofing, local repairs and replacement of damaged roof tiles.
