Water Tight Lean-To

[Markzk]

Hi All,
I was thinking about adding a lean-to the to rear of the house before selling it, the wall is rendered and finish with stones (pebble dashed).

I was wondering if it would be best to chisel off the render where the roof connects to the wall and whether or not this would help weather proof the lend-to, or will I face more/similar problems regardless.

If so, what would be the best way to tackle this.

Thanks for reading

I'd suggest not doing it at all if you are moving as it is unlikely to add any value.

i tend to agree with Colin.

if you do decide to build a lean-to then you are best removing all pebbledash render, from the lead chase and below.

once you have decided upon the roof pitch, angle grind a straight cut at the point where the lead will chase into the brickwork. then jack hammer off all the rendering below this cut.

you will be able to create a rendered drip using a bell bead, that will weather the render-lead join, later on.

Thanks for the replies,

Sorry, by "lean-to" I meant a lean-to conservatory, although I'm not really looking at it from a profit point of view right now, I'd be happy to just gain some hands on experience (without screawing it up and making a loss ).

I thought taking the render off might be the best option,
Thanks again.
