Just a word of thanks for the advice to run a length of string down

Did that yesterday with 1/4" nylon rope and it seems to have solved
the problem!

That will also greatly help the rats to climb up the pipe!

for a rooftop protest about their conditions?

The rats go up the pipe to the roof and look for holes to go into.
Corrugated iron has lots of rat-sized holes especially for rats!

Tie a slip-knot every so often in the rope so the rats snare themselves in
the noose. (Use the rope to pull the bodies out when necessary).
