I have just bought a unit on the top floor of a 4 storey block of units. The
units (us because we are on the top floor) has a concrete slab roof.
Almost every night we are awoken by noise coming from the roof. It sounds
like something is moving in the roof and causing a wood on wood or wood on
steel creaking noise.
It also seems like that it might be over the supporting walls.
We would like advice or any comment please, is this normal, should we be
worried, can it be fixed
Some "experts" that we have spoken to say it is quite normal for a concrete
roof to expand or contract, and this will cause a noise.
We would appreciate any comments please
Climb on your roof and let us know what exactly is on it, it will help.
If you can, post somewhere a photo or 2.
Try also to know what is the overall roof built-up, i.e. the list of
elements from the external visible face down to your ceiling.
Wooden based roofs may make some noise, but usually concrete roofs are
Where is the building (Climatic conditions)?
No! I am afraid that without physically seeing, hearing and assessing it,
the situation will never be remedied. Contact a structural engineer and get
him to review it and if (as I suspect) you have a fault then he will present
it to a court if necessary, as an expert with intimate knowledge of the
situation. If all is well then you can sleep easy in your bed knowing that,
and if necessary a constructor will have a remedy for it.
Best of luck
