Why flashing repairs need detail, not guesswork
Ingress route pinpointed
We inspect each lead detail to find the exact path water is taking in.
Lead formed correctly
Laps, joints and dressings are shaped to suit the roof around them.
Chimney and wall links secured
Flashing repairs are tied back into the chase and surrounding covering.
Where surfaces meet is often where leaks begin
Leadwork has a simple but important job on a roof. It protects the awkward meeting points where chimneys, walls, valleys and adjoining sections come together, which are exactly the spots where water likes to test the detail. If the lead has split, lifted, been poorly dressed or come away from the chase, rain can get behind the covering and travel into the roof unseen for a while before the signs appear indoors. We inspect apron, step and cover flashing details carefully to find the precise route of ingress. Homeowners who contact RedLine Roofing & Homes Ltd for this kind of issue often suspect the chimney first, and sometimes the chimney is guilty, but the close-up lead detail is what tells the full story.
Repaired or renewed with movement and drainage in mind
Good flashing work is not only about filling a gap. Defective sections need to be repaired or renewed with correctly formed joints, laps and secure wall connections that can cope with normal movement and still direct water back onto the roof covering. We also dress the lead neatly to the surrounding roof profile so rain is carried towards the drainage path instead of pooling at the junction. A survey from RedLine Roofing & Homes Ltd looks at failed mortar chases, lifting edges and poor overlaps as part of the same job, because a leak at a chimney or wall connection is usually the result of a detail failing, not a mystery that fixes itself by wishful thinking.
Frequently asked questions
What signs point to failed chimney flashing?
Damp patches near the chimney breast, staining after wind-driven rain, drips in the loft and visible gaps or lifting at the flashing can all point to failure. We inspect the lead details close up because the path water takes around a chimney is often more complex than it first appears from inside the house.
Can flashing leaks be repaired without replacing the whole roof?
Yes, very often. If the main roof covering is still sound, local flashing repair or renewal may be enough to stop the leak. We check the leadwork, the chase and the nearby roof details together first, because there is little point renewing one section if the adjacent detail is failing too.
Why does lead need to be dressed neatly to the roof shape?
Because the lead has to guide water onto the roof covering and towards the drainage path, not leave edges where rain can sit or work its way underneath. Neat dressing, secure fixing and properly formed laps all help the flashing cope with weather and everyday movement over time.
