Solution for leaking lean to conservatory
Discussion
My house has a lean to conservatory. It's a rubbish thing but does give a bit of extra space to a fairly small house.
It used to leak where it joins the wall if there was very heavy rain - so a couple of times a year.
I rent the house out now, and according to the tenants it has got worse over the last 2 years (although I wonder if that's just because there was a lot of heavy rain).
The agency I use did call out contractors who quoted about £500 to redo the flashing, then decided it was too hard and didn't do it.
Tenants move out next weekend and step daughter moves in, so I'll get a better idea of how bad it's leaking now.
But what's the solution - get somebody to fix the flashing where it attaches to the wall?
If I lived there I'd replace it, but that's a waste on a house I won't live in again.
Taking it down is an option but that would look odd - it would leave the raised base, there's a radiator which would have to be removed etc and in not sure it would be much cheaper than replacing it.
I'm really looking for the simplest way to make it waterproof again.

I'm guessing you're going to have to remove some roof panels to access, so you might as well put in a reasonable amount of effort on the actual flashing?
Otherwise, it's hanging out of windows with a mastic gun...
I'd assumed it would be from above with scaffolding (I won't be doing it myself).Otherwise, it's hanging out of windows with a mastic gun...
Depending on the leak and access I've had some success with this stuff on our similarly rubbish conservatory leak.

I can get to some of mine from the first floor window above which helps, otherwise any repairs are very hard.
