Suspicious roof cracks around pipe

[collinsc]

Posting here as this is "roof" related and also "plumbing" potentially...

There is an ominous looking crack and slight bowing around a pipe in our kitchen.

I've only just spotted it, but it could have been there ages...

im wondering if there is a water deposit in the roof from the rain; or it could be nothing..

Photos attached.


Thoughts appreciated.

Many thanks

My guess, & it can only be a guess, is that as the length of pipe has expanded & contracted it has cracked & moved the plasterboard it passes through. The black mould spots look possibly worrying but may be just a bit of condensation. Unless you can gain access from above there is no real way to tell if it is leaking.

Check the flashing as it goes through the roof. It may be leaking..

You provide minimal information, is it a ground kitchen extension? First floor flat kitchen? Etc .Looks like a poor fill job around pipe has just come loose due to movement .
