Flat roof causing damp

Postby mart_reay » Mon Apr 14, 2008 6:09 pm

I live in a mid terrace and have really bad damp coming through most rooms upstairs in my home. I have been onto the roof and there is a pool of water half a foot deep covering my house and next doors. Because of the house being in the middle of a row of terraces the water seems to be gathering worse over my house. Are there any solutions to stop the water coming through. Please help!

Simply Build It

Hi How are you?
you can buy a paint which will help seal your roof but it would be advised to get a new roof installed.
Even if you seal it the water still has nowhere to run and in time will only get though this.
When i do flat roofs i always put a slight fall on it so the water runs off.
It is hard to tell without looking at it what will need replacing, but it will probably need ripping out and re-ply wooded and felted.
If you do get this done make sure they put tilt fillets in to it had a slight slope to take water off and prevent it from holding large amounts.
