Failure of UnderlayLeadwork roofing

Whilst roof tiles and slates are designed to keep out any rain, there is always the chance that strong winds can lead to rain forcing its way through any gaps or underneath the tiles. The underlay is then designed to carry this water away to the guttering however over time, and with continued exposure to the rain, the underlay can begin to rot, not function effectively and ultimately fail, leading to a leak.

Slipped Tiles or SlatesRoof Repairs for terraced houses

Slipped tiles or slates will be very easy to notice and can result in larger amounts of rainwater hitting the underlay and putting it under increased pressure. If pools of water then build up in the area where a tile or slate has slipped, a leak into the inside of the roof is increasingly likely to happen.

Damaged Roof JunctionsLead work for building

A particularly common cause of a leak is through the incorrect installation or damage to the flashing at junctions on the roof. Even the slightest damage can escalate rapidly when a large amount of water is directed to this area and will ultimately result in a leak.

Lean-to Extensions

tiled roofing for housesIf you have a lean-to extension that the water from the main roof on your house is discharged onto, there is a significant chance of this roof leaking. The tiles and underlay will be unable to cope with such large volumes of water over a prolonged period of time and will eventually cave under the pressure, causing a leak.


Blue tiling for housesWhilst not a direct cause of damage to your roof, a poorly ventilated roof space can lead to condensation forming on the underside of the underlay or tiles. This can eventually lead to droplets of water leaking through your ceiling, giving the appearance of a leaking roof.

Now that you are aware of five of the most common causes of a leaking roof, you should be in a better position to evaluate the problem in your home the next time one arises.
