Overhang needed?

[jheyds]

Hi, I'm after a bit of advice. The picture is of my victorian mid terrace house, as you can see the render is failing and underneath is a public footpath, so I need to sort ASAP.
I've contacted a few rendering companies, and so far a couple have got back. One has quoted £1500 to remove and replace and the other quoted £580.
The chap that quoted the highest amount said he wouldn't do it unless there was an overhang on the tiles, and that's the reason it's failed in the first place. However the house is over 100yrs old and I'm assuming it's the original rendering (I could be totally wrong on that though) if so, then it's done pretty well.
My questions areis
1. do i really need an overhang?
2. The prices vary by quite a lot. What's a fair price for just the rendering
3. How should the join between the two properties be? Lead flashing or how it is now... which looks like it's sealed with the render itself.
Any advice would be much appreciated.
Many thanks

OP,
1. Yes, the builder recommending the verge overhang is correct. A 50mm overhang is good.
2. The render & pointed wet verge would need removing. A Cement fibre undercloak would be needed.
3. Tiles near the verge would have to be lifted to enable possible adjustment to the felt and battens.
4. After cleaning or renewing, the tiles would need to be extended about 50mm further out.
5. Neither the wet verge nor the render is original.
6. The fillet of S&C is bad practice - step & cover flashings are best.
7. Who owns the chimney stack?

Hi, thank you so much for the reply and advice.
The neighbour owns the chimney stack and it's his roof that we would need access to (which he has agreed to).
interesting about it not been the original render ( I was unsure) It's not been done in the last 30yrs that's for sure.
Thanks again
