The Situation Most People Are In

A chimney stack starts causing trouble and a homeowner needs to act - but there may be a gap between spotting the problem and having a roofer on site. Weather does not wait. Understanding what is safe to do yourself, what genuinely helps, and what can make things worse is practical knowledge that can limit the damage and the repair cost.

This page covers chimney take-downs specifically - the permanent removal of a redundant stack below roof level - but the interim advice here applies to anyone dealing with a leaking or deteriorating chimney while they wait for professional work to be booked in.

First: Identify What Kind of Problem You Have

Before doing anything, it helps to understand where the water is coming from. Chimney-related damp inside the house usually comes from one of three places:

• Failed or lifted flashings - the lead or mortar seal between the stack and the surrounding tiles. Water tracks in at roof level and can travel some distance before appearing as a damp patch.
• Cracked or open flaunching and pointing - the mortar joints in the stack itself absorb water and release it slowly into the masonry. Damp patches on a chimney breast can appear weeks after heavy rain.
• Rainwater down the flue - on a redundant chimney with no cap or cowl, rain falls directly into the flue and can come through into the fireplace or the void behind a sealed breast.

Knowing which of these is happening helps you decide what interim steps are useful. If rain is coming down the flue, for example, fitting a chimney balloon or a draught excluder inside the fireplace opening is a reasonable temporary measure. If the problem is flashing failure at roof level, there is very little a homeowner can safely do from inside the house to stop it.

What You Can Safely Do Yourself

There are a small number of things a homeowner can reasonably manage without going onto the roof:

• Fit a chimney balloon or draught excluder inside the fireplace opening. These are inflatable plugs that sit in the throat of the fireplace and stop rain and downdraught. They are inexpensive, available from most DIY retailers, and easy to fit and remove. They will not stop water getting in at roof level, but they will reduce rain coming straight down an uncapped flue.
• Protect internal finishes from further damage. If damp is appearing on a chimney breast wall, keep the room well ventilated and remove any wallpaper or non-breathable paint that is trapping moisture against the plaster. Letting the wall breathe slows the spread of salt damage and makes the eventual redecoration easier.
• Place a container to catch drips if water is coming through an open fireplace. Not a permanent solution, obviously, but it protects the floor and furniture while you wait.
• Document the damage. Photographs of damp patches, noting the dates of heavy rain and when patches appear or worsen, are genuinely useful information for the roofer. It helps them assess how long the problem has been running and how much moisture the masonry has absorbed.

What Not to Do Yourself

This is the more important section for most homeowners. The temptation to climb up and sort the problem out is understandable, but chimney work on a pitched roof is genuinely dangerous without the right equipment and experience. Falls from roofs are a leading cause of serious injury in home maintenance accidents. The following should be left to a professional:

• Do not go onto the roof without proper access equipment and training. A ladder leaned against a gutter is not adequate for roof work. Tiles are slippery, rooflines are steeper than they look from the ground, and a chimney stack offers poor and unreliable hand-holds.
• Do not attempt to re-dress or re-fix flashing yourself. Poorly re-dressed lead does not seal correctly and can make the underlying problem harder to diagnose and fix. It can also create water traps that did not exist before.
• Do not apply sealant, mastic or expanding foam to cracks in the stack or around flashings. These products are not a roof repair. They block the visible symptom while water continues to enter by another route, and they make proper diagnosis and repair significantly harder - and more expensive - when the roofer eventually arrives.
• Do not attempt to cap the stack yourself from roof level. Improvised caps - a piece of slate, a sheet of ply, a stone - are not secured and can be dislodged by wind, becoming a hazard to anyone below.
• Do not attempt to knock the stack down yourself. This is probably the most important point. Chimney demolition produces heavy falling debris, and without control measures in place - a catch system, debris chutes, protection to the roof surface below - tiles are broken, gutters are damaged, and there is a serious risk of injury. A chimney take-down is a skilled roofing job, not a demolition afternoon.

Managing the Damp Indoors

If significant water has been getting in for some time, the masonry will be holding moisture and it will continue to affect the inside of the house even after the external source is sealed. Good ventilation is the most useful thing you can do. Keep windows open when weather allows and avoid sealing the affected room with heavy curtains or furniture pushed against wet walls.

Dehumidifiers help speed the drying process, but do not mistake a drying wall for a fixed one. The chimney breast will continue to show salt deposits and possible staining as it dries - that is normal. Only once the roof repair is complete and the masonry has fully dried should you think about replastering or redecorating.

What Happens When the Roofer Arrives

For a chimney take-down, the roofer will assess the stack from roof level before beginning work. They will check the condition of the surrounding tiles, the existing flashings, and the roof structure near the stack position. On a redundant chimney, the plan is to take the stack down to below the roofline, then close the roof with a lead slate and lay in matching tiles.

The lead slate is formed to sit at the pitch of your roof and overlaps the surrounding tiles to shed water away. The tiles disturbed during the work are lifted, the lead slate is fitted, and the tiles are relaid. Any that are cracked or broken in the process are replaced. All the demolished brickwork and debris is removed from site - it does not stay in your garden.

A stack on a two-storey house with good ladder access costs less to deal with than one on a three-storey gable with poor access to the eaves.

Questions Worth Having Ready for the Roofer

When the roofer arrives, or when you speak to them beforehand, these are useful things to ask:

• How will you protect the tiles below the stack during demolition?
• What specification of lead will you use for the slate?
• Can you source tiles that match the rest of my roof?
• Is waste removal included, and how will the brickwork be taken away?
• Will you check the ridge tiles and surrounding area while you are up there?
