Most homeowners have a rough idea of what a chimney take-down involves but aren't sure exactly what happens at each stage or what they should be checking for along the way. This page walks through the process in order, so you know what to expect before, during and after the work.
Before any work is planned, the stack needs to be properly looked at. A ground-level inspection with binoculars can reveal obvious problems - leaning, spalling brickwork, missing mortar, cracked flaunching, damaged or absent pots. But the full picture usually requires getting up close.
The assessment should cover the condition of the brickwork from top to bottom, the state of the flashing at the junction with the roof, and the condition of the roof covering immediately around the base of the stack. Lifted or cracked flashing, slipped tiles nearby, or moss growth concentrated around the base of the stack all point to water having tracked down into the roof structure. Finding those issues before the take-down begins means they can be dealt with as part of the same job rather than left to cause further problems.
It's also worth checking whether the stack is the only one on the property and whether it serves any active appliance. If any part of the house still has a working open fire, log burner or solid fuel Aga connected to that flue, the stack isn't redundant and the situation is more complex. A flue survey (CCTV or visual inspection) may be needed before a decision is made.
Safe access is the foundation of any chimney job. For a standard two-storey house, a scaffold is erected around the chimney - either a full platform or a chimney scaffold depending on the stack's position and height. This allows the roofer to work safely, to control how bricks come down, and to manoeuvre materials without risk of damage to the roof or surroundings.
Scaffold is typically in place for the duration of the job and is struck once the work is complete and inspected. The time on hire is part of the job cost, and it should be included in the quote from the start. If access is particularly straightforward - a single-storey extension or a low rear outbuilding chimney - a tower scaffold or heavy-duty crawling boards may suffice.
Before the scaffold goes up, any fragile items below should be moved - garden furniture, skylights, conservatory roofs nearby. Good practice is to sheet over the area beneath the stack during demolition to catch loose mortar and brick dust.
The pot comes off first. If it's intact, it can be kept or disposed of - some homeowners want to keep decorative Victorian pots, which is perfectly reasonable and easy to accommodate. The flaunching (the mortar bed the pot sits in) is broken away next, then the brickwork is taken down course by course.
Bricks are lowered or passed down by hand where possible, not thrown. A skip or large bags at ground level receive the debris. Working course by course rather than knocking down in sections protects the roof below and keeps the work controlled. For stacks being removed to below roof level, the demolition continues until the remaining brickwork sits below the line of the roof surface.
During the demolition, the condition of the brickwork beneath any rendered or painted surface becomes visible. Sometimes the inner core of a stack is in worse condition than the outside suggested. That's not unusual in an older stack, and a good roofer will flag it and discuss the implications with you before carrying on.
Before the roof opening is closed over, the flue itself needs to be addressed. Any remaining void into the chimney breast below should not be left as an open, unsealed shaft inside the house - it can draw cold air and allow birds or pests to enter. A ventilated cap at ceiling level (inside the house, fitted by a builder at a later stage) or a simple sealed cover is the usual solution. The roofer's job is to make sure no open void is left above the ceiling line once the roof is made good.
This is the part that determines how the job looks and performs long-term. The opening left by the removed stack is fitted with new timber battens, laid to match the existing batten gauge. A section of breathable roofing membrane (or traditional felt on older roofs) is dressed in to keep the junction watertight before the tiles or slates go on.
Tiles or slates are then laid in courses, each one interlocking with or overlapping the existing covering on either side. The new section has to be fully integrated - not just laid on top or tucked in loosely, but properly bedded and lapped so water sheds cleanly off the whole surface. Ridge tiles, hip tiles or any other detailing that runs through the affected area is reset if disturbed.
Where the stack met the slope of the roof, lead flashing will have been in place. With the stack gone to below roof level, there's no remaining junction to flash - which removes a known weak point from the roof permanently. If a stub is left, new lead flashing is cut and dressed into the brickwork and under the tiles, replacing whatever failed original flashing was there.
Once the tiling is complete, the area is checked from the scaffold before it comes down. Any pointing that needs freshening around the repair, any ridge that needs re-bedding, or any displaced tile nearby is attended to at this stage. It's much easier to spot and fix these things while the scaffold is still standing than to come back once it's gone.
Debris from the stack goes into the skip or bags at ground level. The scaffold is struck, any protective sheeting removed, and the garden or drive beneath is left clear. The expectation should be that the area around the house is left in the same state it was found, other than the stack being gone and the roof being sound above it.
