The work

Most stubborn leaks turn out to be leadwork

Leadwork is the metal that seals the joints a roof cannot tile over: chimney flashings, soakers and back gutters, valley linings, abutment flashings where a roof meets a wall, dormer cheeks and parapet gutters. Most persistent leaks that survive several repairs turn out to be leadwork that was done wrong.

The common faults are all avoidable: a bay made too long so thermal movement splits it, the wrong code of lead for the exposure, a flashing not chased far enough into the joint, or a bead of sealant run along the top edge instead of the lead being re-dressed. Getting it right first time ends the cycle of repairs that never quite hold.

We use the correct code, keep bays within the recommended lengths, and chase and wedge the flashing properly rather than sticking it on. Sound lead is re-dressed and reused where it can be, and you get an honest view of what needs renewing and what does not.

The process

How leadwork normally runs

  1. 01

    Find the actual fault

    Split, wrong code, over-long bay or a past mastic repair. Each needs a different answer.

  2. 02

    Specify the code

    The lead code and bay lengths set to the exposure and the detail, not to whatever was there before.

  3. 03

    Form and dress

    Lead cut, bossed or welded to shape, then dressed into the joint and wedged.

  4. 04

    Point and finish

    The chase pointed up and the lead patinated so it weathers evenly.

Pricing

What moves the price

Every roof is different, so the quote follows a look at yours rather than a figure over the phone. The roof, and the loft where the fault is a leak, both get checked before anything is priced.

The quote you get back is itemised: access, materials, labour and clearing the site. Where the job needs scaffold, that goes in the figure from the start, not added later. The points on the right are what make the biggest difference to where the price lands.

What we look at

  • The lead code required for the exposure and the detail
  • How much lead by area and how complex the shapes are
  • Whether existing lead can be re-dressed or has to be renewed
  • Access and scaffold, particularly around a chimney

FAQs

Things people ask about leadwork

Someone sealed my flashing with mastic and it still leaks. Why?

Mastic sits on the surface and lead moves with temperature, so the bond breaks and water gets behind it. Worse, it hides the split underneath. The lead has to be re-dressed or renewed and the chase pointed properly.

What is a lead code?

It is the thickness. Higher codes are thicker and stand more exposure and movement. Using too thin a code in an exposed valley or a long flashing is a common cause of early splitting.

Why does new lead look patchy?

Fresh lead oxidises unevenly and can stain the tiles below. It is normally treated with patination oil when fitted, which evens out the weathering and stops the staining.
