A leaking roof can cause a number of issues. You may first notice it when it rains heavy or rains with strong winds. Often you will notice water pouring through celling’s or even light fittings and this can not only be inconvenient but also extremely dangerous. If you discover water leaking into your home and it is near electrics, the first thing to do is to turn off the power at the fuse board. Water and electrics do not mix and although you may struggle with no lighting it is the safest thing to do. Next you need to try and identify where the water is coming from. If it is leaking through a light fitting, it may not be that the leak is right above it as the water will run down channels until it finds a hole that it can pour out of. If it is at the edge of the wall then it may well be an overhanding tile is the issue. In the middle of the roof, there is likely to be a few broken tiles and possible damaged flashing that is causing it.
No one will usually be able to assess the damage whilst it is still raining so try and catch as much water as possible until you are able to get someone to investigate and repair any damage. It may be covered by your home insurance so be sure to check before proceeding with any repairs.
