Why chimney faults are checked by Fell Roofing
Stack and roof checked together
We assess masonry, flaunching, coverings and junctions as parts of the same weather line.
Lime mortar flaunching included
The top of the stack can be repaired to help it shed water away from the pots again.
Local or wider repair guidance
We explain when repointing is enough and when the chimney needs more involved work.
Treating the chimney as one roof-level repair area
A chimney can leak or deteriorate in more than one place at once. Mortar joints may weather back, masonry can loosen, the crown can crack, flaunching around the pots can fail, and the surrounding roof junction can start taking water. That is why chimney work needs looking at as one repair area rather than a collection of separate symptoms. With Fell Roofing, chimney roof repairs cover stack repairs, repointing and renewal of deteriorated mortar joints, along with lime mortar flaunching where the top of the stack needs help shedding water properly again. We also assess the adjoining roof covering and the weatherproof junction, because a chimney leak does not always care which exact line in the brickwork it first crossed.
Repoint, rebuild or carry out wider remedial work
Some chimney problems can be solved with local repointing where the structure remains sound, and the deterioration is limited to the joints. Others need more extensive work because the masonry, crown or roof-level details have all started to fail together. We explain that difference after inspection, so you can judge whether a focused repair is enough or whether larger remedial work makes better sense. A quote from Fell Roofing stays free and without obligation, and it gives you a practical route to stop a loose, weathered stack shedding water and debris where your roof would rather do without both.
Frequently asked questions
When is chimney repointing enough on its own?
If the main structure is still sound, and the deterioration is limited to weathered or open mortar joints, repointing may be enough. If the masonry is loose, the crown has failed or the surrounding roof junction is also letting in water, broader chimney or roof-level repairs are usually the wiser option.
What is flaunching, and why does it matter?
Flaunching is the mortar around the base of the chimney pots at the top of the stack. Its job is to help shed water away from the openings and top surface. When it cracks or weathers away, water can linger and work into the stack, so renewing it is often an important part of chimney repair.
Do chimney leaks always come from the brickwork itself?
No. Water can enter through open joints, failed flaunching, loose masonry or the roof junction around the chimney. That is why we inspect the stack, the adjoining covering and the flashing detail together rather than assuming the visible damp patch automatically points to just one cause.
