I've got a flat roof which is slightly leaking after heavy rain. I would estimate that it was *refelted about six years ago and top coated / bitumened about three years.
I've got up on the roof and had a good look and can't see any obvious holes or signs or blistering.
It has detached itself from the lead flashing a little in places.
There are places on the roof where puddles form.
Is it a case that the felt gets so saturated from the puddles that it begins to leak?
Any other possible reasons why it would leak?
* If I remember rightly it was refelted over the old felt and base boards.
Thanks in advance for any replies.
