We have a flat rubber roof which was put on about 18 months ago.
About a year after it was put on we had a section of our bedroom ceiling collapse.
This was caused by water draining to a point in the roof deck over this point of the
Ceiling and then falling down on the ceiling. There is no leak actually over this point.
It seems to be getting under the rubber and then moving to this point.
(This means the roof deck is not correctly sloped everywhere, but I don't
Think anything can be done about that).
Since then the roofer has been out many times, and made various repairs
To the rubber, the skylights and perhaps elsewhere. The problem seems to
Have improved but we still get water emerging from the roofdeck at this point
During heavy rain.
(We have not repaired the ceiling, and this is one of the lowest points of the
Roof deck, so any water which gets in will drain to this point).
The water seems to be travelling from somewhere else. It takes about 8 hours
After the start of heavy rain for it to emerge, at which point its just a drip.
However this drip goes on for a while and when we collect it in a bucket it can
End up being a substantial amount of water - maybe up to a quart.
Its been about six months since the ceiling collapse, and I'm at a bit of a loss
As to what to do. Can anyone suggest a way to help find the leak or other things
To look for. Is there something that could give us a clue - for example popped nails (which we have a lot of) ? A friend suggested it could be the tuckpointing on the
Chimney or the parapet wall (we live in a towhouse complex).
Any help would be greatly appreciated.
