Is a Leak Coming From a Junction?
Failed flashing is one of the most common causes of a roof leak that has nothing to do with the tiles themselves.
Lead lifting away from the wall
Visible gaps where lead has pulled away from brickwork or render let water straight in behind the flashing.
Cracked or split lead sheet
Decades of thermal movement can cause lead to crack or "creep," especially on older or poorly detailed installations.
Missing sections of lead
Whether from storm damage or theft, a missing flashing section needs urgent temporary cover as well as permanent repair.
Damp patch near a chimney or wall
Staining near a junction is often flashing, though it can also be the masonry itself — worth confirming which before repairing either.
Leadwork & Flashing Services, Fixed Price
Every junction on a roof needs its own flashing detail — every job priced upfront, no site visit required for straightforward work.
Chimney Flashing
Repairing or replacing the stepped and apron lead flashing where a chimney meets the roof — the single most common source of chimney-area leaks.
Valley Flashing
Repairing or renewing lead valley linings, which carry a large volume of water and take heavy wear over time.
Abutment & Wall Flashing
Repairing flashing where a roof abuts a wall or parapet — a common failure point on extensions and side-return roofs.
Replacing Stolen or Missing Lead
Fast replacement of stolen or storm-damaged lead, with the option to discuss lead alternatives or anti-theft security clips to reduce the risk of it happening again.
Leadwork & Flashing on Hillingdon's Housing Stock
Hillingdon’s property types shape the most common flashing jobs here.
Shared Stacks in Ruislip
Many of Ruislip's period terraces have chimney stacks shared across the party wall, so flashing repairs often mean coordinating access with a neighbour.
Northwood's Period Properties
Northwood's older detached and semi-detached houses often have original lead flashing now due replacement at valleys and abutments.
Where Extensions Meet the Main Roof
Rear extensions across the borough's suburban streets mean the junction where a flat roof meets the original pitched roof is a common flashing failure point.

What Hillingdon Homeowners Say
Uxbridge · Chimney Flashing Repair
“Had a leak that turned out to be the flashing, not the chimney itself as we’d assumed. Quoted over the phone from photos, fixed same day, dry ever since.”
Northwood · Stolen Lead Replacement
“Lead was stripped from our flat roof edge overnight. Replaced fast with security clips fitted this time, and a sensible chat about alternatives so it’s less of a target going forward.”
Ruislip · Valley Flashing Replacement
“Valley between two roof sections had been patched twice by previous owners. Proper lead lining put in this time, quoted upfront, no drama since.”

Leadwork & Flashing in Hillingdon, Answered
Both are common causes of damp near a chimney and they need different fixes — failed lead flashing lets water in at the roof junction, while porous brickwork or failed mortar lets water through the masonry itself. We check both when we look at it. If it turns out to be the masonry, see our Chimney Repair & Repointing page.
Lead expands and contracts with temperature, and over decades this movement — known as "creep" — can crack it or work it loose from the wall. Poor original installation accelerates this significantly, which is why quality of fitting matters as much as the material itself.
Yes, unfortunately this is something we deal with regularly. We can replace missing lead quickly, and discuss options like anti-theft security clips or lead-alternative materials that make a repeat theft less likely.
Genuine lead is the traditional standard and extremely durable, but its scrap value makes it a theft target. Modern alternatives look similar and perform well for most applications, at a lower cost and with no scrap value to attract thieves — worth discussing if theft is a concern for your property.
A localised repair to one section is usually completed the same day. Larger jobs like a full valley or chimney flashing replacement typically take a day.
