What Lead Does on Your Roof

Tiles and slates keep the rain off the open slopes, but the awkward joins are where lead earns its keep. Chimney flashings and soakers, valley linings, the junction where an extension roof meets the house wall, dormer cheeks, bay window roofs and back gutters behind parapets are all lead territory.

Get these details right and nobody ever thinks about them again for decades. Get them wrong and the leak shows up indoors metres away from the fault, usually long after the contractor has driven off. We treat leadwork as a craft rather than a line on a quote for that reason, and we would rather turn a job down than dress a flashing badly.

Most of the lead failures we see around Chelmsford and across Essex are not the lead's fault. They are fitting faults, and they are all avoidable.

Why Lead Fails

Lead moves. It expands in summer sun and contracts in winter frost more than most roofing materials, and it has to be fixed and dressed to allow for that movement. Fixed too tightly, or laid in sheets too big for the detail, it works itself until it cracks at the worst possible place. Look at an old lead valley split clean across its middle and you are looking at exactly that.

Poor dressing causes the rest. Lead poked into a mortar joint instead of properly dressed into a chase, soakers left out at a chimney, or a flashing left sitting proud so wind gets underneath it, all of them let water in while looking finished from the ground. Storms lift badly fixed lead too, and after a windy night we get calls where the flashing is flapping like a flag.

And of course lead is valuable, so it gets stolen. If you have come back to bare, exposed joints where lead used to be, that is a make-safe and re-lead job, and we handle those as a matter of urgency.

The Craft Side of It

Proper leadwork is measured, cut, dressed and fixed to suit the detail it serves. Lead is dressed over a roll or into a drip so each bay can move on its own. It is chased into brick joints and pointed in, or dressed over timber rolls and clipped at the right spacing so the wind cannot get a grip. Shapes are bossed or welded, not folded and forced.

None of that shows from the street. What shows, years later, is the difference: a flashing that is still doing its job while the one next door has cracked twice. Lead done right is one of the longest-lasting materials on any roof, which is exactly why cutting corners on it is such a false economy.

It sits alongside our other traditional work too. Where a lead detail meets slates or tiles, the same crew handles both, which you can read more about on our slating and tiling in Chelmsford page.

Repair or Renew

Not every lead problem means new lead. Sound lead that has worked loose can often be re-dressed and re-fixed, and a flashing that has slipped out of a chase goes back in properly without replacing the bay. We would always rather save good lead than skip it.

Split, fatigued or undersized lead gets replaced, bay by bay, to the same detailing as the original but with the movement built in that the old job was missing. What you will never catch us doing is smearing mastic over a crack and calling it a repair. Mastic hides the problem for a season and makes the proper job harder when it inevitably comes back.

If water is already finding its way indoors, our roof repairs in Chelmsford page explains how we trace a leak to its source, and our emergency roofing page covers storm-lifted lead and make-safe work.

Leadwork FAQs

Do you take on small lead flashing repairs?
Yes. A single flashing that has slipped out of its chase is a small job and we treat it that way. Small lead jobs done early are what stop the ceiling jobs later.
Why does my flashing keep leaking after it has been patched?
Because a patch does not deal with why the lead failed. If the bay was fixed too tight or dressed wrongly, it keeps working until it cracks again, mastic or no mastic. The lasting fix is to replace or re-dress the bay so the lead can move as it was designed to.
Can lead be repaired or does it always need replacing?
Sound lead can usually be re-dressed and re-fixed. Split or fatigued lead gets replaced bay by bay. We save good lead wherever it makes sense to.
What is the difference between flashing and soakers?
Soakers sit under each tile or slate against a wall or chimney and catch the water running down that face. The flashing covers the top of the soakers and turns into the brickwork chase. One without the other is why so many chimneys leak.
Do you cover all of Essex and London for leadwork?
Yes, within a 50-mile radius of Chelmsford. If you are right on the edge of that, ring us anyway and we will give you a straight answer.
