Why Highpoint Roofing checks the junction, not just the stain
Vulnerable edges sealed
We seal the awkward junctions where ordinary roof coverings cannot cope alone.
Formed to last longer
Correct shaping and overlap help the lead stay watertight for longer.
Hidden leaks reduced
Good lead detailing can stop hidden leaks around an otherwise sound roof.
Leaks often start at the roof junction
Some of the most stubborn roof leaks begin where one part of the roof meets another. Around chimneys, abutment walls and changes in roof level, properly formed leadwork seals the transitions that ordinary coverings cannot manage on their own. When lead has lifted, split, been poorly lapped or started to fail at the fixings, water can creep in behind what otherwise looks like a sound roof. In Dartford, we inspect those weak points carefully before we repair or renew anything. If you ask Highpoint Roofing to check a damp problem around a junction, we look at the lead detailing as closely as the covering beside it.
Good leadwork has to move and stay sealed
Lasting leadwork depends on shape, overlap and allowance for movement. If those details are wrong, even new material can fail early. We repair and renew chimney flashings and leadwork at roof junctions with the aim of sealing the vulnerable edge properly, not merely tidying the surface. That matters because water around a failed flashing can travel unseen and damage the surrounding structure before it shows itself indoors. A sound piece of lead detailing often makes the difference between a roof that copes quietly and one that keeps surprising you.
Frequently asked questions
What are the signs that roof leadwork is failing?
Common signs include leaks around chimneys or abutment walls, lifted edges, visible splits, poor previous patching and damp that keeps returning around roof junctions. Because water can travel behind the surface, we inspect the lead and the surrounding materials together.
Can chimney flashing be repaired, or does it always need renewing?
Some lead defects can be repaired if the material around them is still sound and the detailing can be restored properly. Where the lead has split, lifted badly or was poorly formed to begin with, renewal may be the more dependable way to stop the leak.
Why does lead need room for movement?
Lead expands and contracts with temperature changes. If it is fixed or shaped without allowing for that movement, it can stress, crack or pull away from the surface sooner than it should. Good detailing takes that behaviour into account from the start.
