Stack Junctions on Tonypandy Roofs
Where a chimney passes through a roof there are four separate weatherings doing four separate jobs, and on a roof on original battens in a continuous row they are an apron at the front, step flashings and soakers up the sides, and a back gutter behind. On these Rhondda slate terraces all four are the same age as the roof. On a roof on original battens in a continuous row a leak near a chimney is far more likely to be one of those four than the stack itself.
What This Covers
- Chimney leaks
- Failed flashing
- Water around chimney stacks
- Water ingress connected with the affected detail
- Localised weathering or damage requiring repair
The Back Gutter
The back gutter behind the stack is the detail that fails most, because it collects everything wind funnelled straight down the Rhondda sends down the slope above it. With rain hitting the terraces side-on that is a great deal of water arriving in a small tray, and on these Rhondda slate terraces it is also where leaves and moss collect and sit.
Why It Is Awkward
A stack junction sits mid-slope with a vertical obstruction in the middle of it, so with access extremely steep and narrow it usually needs a scaffold rather than a ladder to be worked on properly. Because work on one roof here touches two neighbours', doing the flashing and any stack repointing in one visit saves the access cost twice.
What a Proper Job Looks Like
Step flashings chased individually into the bed joints, soakers interleaved with the covering, an apron at the front and a properly formed back gutter — on a roof on original battens in a continuous row that is the whole detail and nothing less weathers a stack. A continuous strip of lead run round the stack and sealed with mastic is what we are usually removing, and with wind funnelled straight down the Rhondda it buys about a winter.

Chimney Flashing Repairs in Tonypandy — Common Questions
What are common signs that I may need chimney flashing repairs in Tonypandy?
Where a chimney passes through a roof there are four separate weatherings doing four separate jobs, and on these Rhondda slate terraces they are an apron at the front, step flashings and soakers up the sides, and a back gutter behind. With rain hitting the terraces side-on that is a great deal of water arriving in a small tray, and on a roof on original battens in a continuous row it is also where leaves and moss collect and sit.
Can a small defect cause an internal leak?
Yes. The kind of defect behind chimney flashing repairs lets water into the structure on these Rhondda slate terraces, and it can travel a long way before it shows on a ceiling. That is why the source of a chimney flashing repairs problem is traced rather than guessed at from the mark inside.
Will the whole roof need replacing?
Usually not. Chimney flashing repairs is repair work, and on a roof on original battens in a continuous row the covering around the defect is generally sound — whether a repair is the right answer depends on how far the deterioration has gone beyond the part you can see.
Can you inspect the problem before recommending work?
Yes, always. Given work on one roof here touches two neighbours', a chimney flashing repairs job on these Rhondda slate terraces is looked at before anything is recommended, and you get told what was actually found rather than a figure guessed from the pavement.
Do you cover other roof repairs in Tonypandy?

Do you cover Tonypandy and the surrounding area?
Yes — chimney flashing repairs throughout Tonypandy and the places around it, including Llwynypia, Penygraig, Clydach Vale, Trealaw and Williamstown.
What does a repair like this cost?
Two things set the figure for chimney flashing repairs: how far the defect has actually gone, which needs somebody to look at it, and the access. With access here hemmed in, with no rear access and nowhere to stand a vehicle, that second one moves the price of chimney flashing repairs more than the materials do, and it is why a figure over the phone is a guess.
Can you look at other things while you are there?
Yes, and it is worth it — given work on one roof here touches two neighbours', safe access to the roof is most of what a visit costs, so anything else wanting attention is far cheaper dealt with on the same day as the chimney flashing repairs.
