Why Water Doesn't Always Enter Where the Leak Appears đź’§đźŹ
When a damp patch appears on a ceiling or wall, the natural assumption is that the problem must be directly above it. In reality, water ingress is rarely that straightforward. Water can enter a building through a defect in one area and then travel surprisingly far through the structure before it finally reaches a point where it becomes visible internally.
Once water gets beneath a roof covering or through an external defect, it can follow roof timbers, membranes, insulation, pipework and other parts of the building. Gravity will eventually bring it down, but the route it takes along the way means that the damp patch you can see could be several feet away from the actual point of entry.
There are many potential causes, from slipped or damaged roof tiles and deteriorating flashing to failed joints, cracked masonry, chimney defects or problems with guttering. Sometimes more than one issue can be contributing to the problem, which is why simply repairing the area immediately above a visible leak isn't always enough.
This is where a thorough inspection becomes important. Rather than treating the visible damp as the problem itself, the aim should be to understand how the water is getting into the building, the route it is taking and why it is appearing in that particular location. Finding the original source gives you a much better chance of carrying out the right repair first time and preventing the problem from returning.
At FRR Midlands, we regularly investigate water ingress and roofing problems across a wide range of properties. Experience tells us that the most obvious answer isn't always the right one, so taking the time to properly investigate a leak can save unnecessary repairs and further damage later on.
When it comes to water ingress, where the leak appears is only part of the story.
