01 — THE PROJECT

Lead roofing across a complex railway structure

The Lead Lads® completed the specialist lead sheet coverings to the pedestrian footbridge at Selby Train Station in North Yorkshire.

Unlike a conventional roof, the bridge combines long sloping elevations, changes in level, stepped stair sections, core-roll joints, ridge geometry and numerous interfaces where separate parts of the structure meet.

Following renewal of the structural framework and timber supporting surfaces by the principal contractor, our work concentrated on setting out, forming and installing the Code 5 lead coverings across the bridge.

02 — THE GEOMETRY

More structure than roof

The footbridge does not present a single uninterrupted roofing plane.

Its geometry changes through the bridge span and into the stair towers, creating different slopes, stepped sections, changes in height and multiple intersecting details.

Each lead bay therefore had to be understood in relation to the structure around it rather than repeated as a standard roofing module.

The long bridge elevations could be set out in a comparatively regular sequence, while the stair sections required more individual pieces and substantially more interface detailing.

03 — THE LEADWORK

Building one covering from individual sections

The principal contractor installed the supporting timber substrate and wood core rolls to the agreed setting-out dimensions.

Our leadwork then progressed elevation by elevation, with individual sheets formed around those rolls to create the principal weathering bays.

At the upper junction, the opposing bridge slopes were resolved through a separately formed apex capping. Lead tabs, laps and the interfaces between the capping and roll details had to maintain continuity while still accommodating normal sheet movement.

The result is a large-scale covering assembled from individually considered sections rather than one continuous skin.

04 — STEEL + TIMBER

The lead follows the supporting structure

The finished leadwork is only the external weathering layer of a much larger construction.

Beneath it sits the renewed steel bridge framework and supporting timber substrate installed by the principal contractor.

The accuracy of the substrate and core-roll arrangement directly influences the finished leadwork. Rolls establish sheet divisions and joint positions, while the supporting surface provides the geometry against which the lead is dressed.

Close coordination between structural, carpentry and leadwork packages was therefore essential before installation progressed.

05 — MOVEMENT + RESTRAINT

Secure the sheet without locking it down

A structure of this scale exposes substantial areas of sheet lead to changing temperatures and weather conditions.

The coverings were therefore divided into individual sections with laps, rolls, tabs and compatible clips used as part of the overall movement strategy.

Copper and stainless-steel clips were incorporated where appropriate to restrain vulnerable edges and sections without unnecessarily preventing normal thermal movement.

06 — SIGNATURE DETAIL

The stair tower interfaces

The most technically demanding areas occurred where the regular bridge elevations transitioned into the stair structures.

Here the leadwork had to negotiate changes in height, direction and supporting geometry while maintaining continuity with the adjoining bays.

Standard repeated pieces gave way to bespoke sections, local flashings, dressed interfaces and carefully resolved overlaps.

This is where the project becomes less about laying sheets and more about interpreting a three-dimensional structure in lead.

07 — COORDINATION + SUPPORT

Preparing for specialist sheet leadwork

  • New steel bridge structure reviewed before lead installation
  • Timber supporting surfaces inspected
  • Wood core-roll layout checked against the leadwork setting out
  • Bridge slopes and individual elevations assessed
  • Apex junction and ridge geometry reviewed
  • Stair tower interfaces and height changes identified
  • Installation sequence coordinated with the principal contractor
  • Access and live-station constraints incorporated into planning
  • Suitable separation layer installed beneath the lead where required

08 — LEADWORK INSTALLATION

Forming the bridge covering

  • Code 5 rolled lead sheet set out to the bridge geometry
  • Individual bays formed to each principal elevation
  • Lead dressed around the timber core rolls
  • Roll interfaces and laps completed progressively
  • Central apex capping installed between opposing slopes
  • Lead tabs formed at capping and lap interfaces
  • Stepped bays formed through stair sections
  • Bespoke flashings installed around changes in level
  • Complex intersections bossed or welded as appropriate
  • Copper and stainless-steel clips used where required
  • Completed laps and interfaces inspected progressively
  • Finished leadwork protected through remaining contract works

10 — THE CRAFT

Large-scale traditional leadwork

  • Lead bay setting out
  • Lead dressing
  • Lead bossing
  • Lead welding
  • Core-roll detailing
  • Stepped bay formation
  • Apex and ridge capping
  • Lead tabs and lap detailing
  • Interface flashing
  • Copper clip formation
  • Stainless-steel restraint detailing

The project combines traditional hand skills with the coordination required for a large engineered structure.

11 — PROJECT RECORD

Structure.
Sections.
Leadwork.

The Selby project record captures considerably more than a finished lead roof.

It shows the progression from the underlying bridge construction through the individual leadwork operations to the completed covering — useful evidence of the amount of hidden work behind the final appearance.

12 — RAIL INFRASTRUCTURE

Traditional material within an operational environment

Selby Station opened in the nineteenth century and remains part of an active railway network.

The footbridge project therefore combined traditional sheet-lead workmanship with the practical constraints associated with working on transport infrastructure.

Access, sequencing, interfaces with other trades and protection of completed work all became part of the delivery process.

This is an important distinction: specialist leadwork at this scale depends as much on coordination and planning as it does on the final hand-formed details.

14 — WHAT THIS PROJECT SHOWS

Traditional leadwork scales far beyond domestic roofing

The Selby footbridge demonstrates the adaptability of sheet lead.

The same underlying principles used on a bay roof or lead gutter — support, sheet dimensions, movement, laps, rolls and compatible restraint — can also be applied to a much larger and more geometrically complex structure.

What changes is the scale, coordination and number of interfaces involved.

Rather than simplifying the craft, a project of this size magnifies the importance of correct setting out and disciplined detailing.

PROJECT TAKEAWAYS

  • Large lead coverings still need to be broken into manageable sections.
  • The supporting substrate determines the finished geometry.
  • Core-roll layout needs coordination before sheet installation.
  • Opposing elevations require a properly resolved apex detail.
  • Stair towers create bespoke junctions and stepped bays.
  • Clips and tabs restrain lead without unnecessarily locking it down.
  • Complex infrastructure projects depend on trade coordination as well as craftsmanship.

15 — FREQUENTLY ASKED

Railway footbridge leadwork questions

Why use lead on a railway footbridge?

Sheet lead can form durable weathering over complex shapes and can be divided into individual sections around curves, slopes, rolls and structural junctions.

What lead was used at Selby Station?

Code 5 rolled lead sheet was used for the bridge coverings on this project. Lead selection for another structure should reflect the particular sheet dimensions, geometry, support and specification.

Why are timber core rolls used?

Core rolls create raised joints between adjacent sections of lead and help divide a larger covering into individual bays while forming a traditional weathering detail.

What makes stair towers difficult to cover?

They introduce changes in direction, height and slope, meaning fewer details can simply be repeated. Individual sheets and flashings have to be formed around the actual geometry.

Why are clips used in lead roofing?

Compatible clips can help restrain edges and sections of sheet while still allowing the lead to respond to normal thermal movement.

THE LEAD LADS® / PROJECT ARCHIVE
