Ok, no replies, so I'll be more specific. I have a 2 up 2 down mid terrace property.  I've had chimney flashing and soakers replaced on my side of the chimney, could someone please give me a rough ball park figure for that?  

If it will be of consequence, I am in Yorkshire.

Many thanks.

I agree with Woodsmith, there are too many imponderables to answer with any certainty.

It's not in itself a difficult or time-consuming job, about half a day's work for a "simple" replacement, but much will depend on what's found when you're up there.

And as said, it depends on whether the job was done the "cheap" way with a ladder to the eaves and a cat-ladder to the ridge...

...or (to keep Health & Safety happy) the expensive way with scaffolding.

Even if it was just a half day's job, I doubt many guys would bother turning out without charging for a full day to cover travel and the fact that it's spoiled a full day's job somewhere else.
