Keep rain moving down the roof
Water path investigated
We inspect beyond the damp mark to locate the likely entry point.
Local repair assessed
We retain sound lead where a focused and durable repair is suitable.
Adjacent materials checked
We consider chases, mortar and roof coverings around the flashing.
Seal the vulnerable chimney roof junction
Leadwork guides rain away from the point where your chimney passes through the roof. Step flashing follows the roof slope, while cover flashing protects the upper edge and chase. If those details split, lift, pull away or deteriorate, water can find its way behind the covering and appear inside. We inspect the lead, mortar chases and surrounding slates or tiles because the wet patch below may not sit under the original entry point. First-hand experience of failed chimney leadwork helps us focus on this common leak route without assuming every damp mark needs the same repair.
Repair sound details and replace failed ones
A contained defect may suit a local repair when the remaining lead is properly formed and secure. Extensively failed, poorly fitted or deteriorated sections may need replacement instead. We shape and secure the detail so water returns onto the roof covering while leaving the lead able to move as it should. The adjoining masonry and roof materials are checked at the same time, avoiding a neat lead repair beside a cracked tile or failed chase. For chimney leadwork repair in Kendal, we match the scope to the condition found.
Frequently asked questions
How do I know chimney flashing has failed?
Lifted edges, splits, loose sections and gaps at mortar chases are visible signs. Indoors, you may find staining near a chimney breast after rain. Similar leaks can come from masonry or roof coverings, so inspection should confirm the route before repair.
Can damaged chimney leadwork be patched?
A local repair may be suitable when damage is limited and the surrounding lead remains correctly formed and secure. If leadwork has failed across a larger area or was poorly detailed, replacement may give a more dependable result.
Why can a roof leak appear away from the chimney?
Water can enter at the flashing and then track along battens, felt, rafters or other roof components before dripping inside. We inspect the external junction and surrounding materials instead of judging the source from the ceiling mark alone.
