The conservatory is leaking. It's a wooden, Edwardian, lean-to style, which
joins the garage (yes, that converted one) on one side, and the rear of the
house on the other.
At the point where it joins the walls, it seems that the flashing (if that's
what it's called - a wide strip of sticky looking black tape) is failing.
Q1 - what's the best, and safest way to get onto that conservatory? I cannot
see any fixings into the walls (but they may, I guess, be covered by the
existing flashing). I know I'll need to use some system of crawl boards, but
I'm petrified that my 15st will come crashing through.
Q2 - what's my options for re-sealing these edges? Obviously the old stuff
will need to come off. Will it come away cleanly, or need burning off or
something? Is there anything better than this 'tape' that I can use to
re-seal it following removal?
