01 — THE PROJECT

Restoring one of Walmgate’s prominent historic buildings

2 Walmgate is a Grade II listed building occupying a prominent position within York city centre and extending directly alongside the River Foss.

Neal Roofing, formerly Geoff Neal Roofing, was appointed following a change of ownership to undertake an extensive programme of roof restoration and external repair before the building’s residential accommodation could be brought back into effective use.

The project developed into a major conservation exercise involving reclaimed Welsh slate, extensive leadwork, chimney rebuilding, structural timber repair, specialist access and full external decoration.

LOCATION

York City Centre

02 — EXISTING CONDITION

Long-term neglect had affected the complete roof envelope

The property had received limited maintenance over an extended period and deterioration was evident across the roof, chimneys, lead gutters, perimeter joinery and external elevations.

Large areas of the timber structure supporting the perimeter gutter had decayed following persistent water ingress.

The principal roof covering had also been altered historically, with concrete interlocking tiles installed in place of the more appropriate natural slate covering.

03 — SITE CONSTRAINTS

A constrained city-centre site beside the River Foss

Access was one of the defining challenges of the project.

Walmgate is a busy route through central York, with significant pedestrian movement, neighbouring commercial premises and restricted space for site facilities.

The riverside elevation presented an additional complication because conventional scaffold standards could not simply be founded within the River Foss.

A bespoke access solution was therefore required before conservation work could begin.

Reclaimed Welsh Slate

Traditional natural slate reinstated across the prominent city-centre roofscape.

Leadwork

Extensive perimeter and central lead gutters formed over reconstructed timber substrates.

City Conservation

Complex access, listed fabric and extensive external repairs delivered as one contract.

04 — SPECIALIST ACCESS

Building a working platform above the River Foss.

The access solution was itself a significant temporary-works exercise.

The riverside scaffold was developed from openings within the lower part of the building and projected over the river before being extended vertically to provide safe access to the roof and elevations above.

The structure also had to accommodate the practical requirements of a long-duration construction project without obstructing the restricted public realm on Walmgate.

A working platform was developed to support site facilities, material storage and the controlled movement of materials through the project.

This specialist access strategy made the subsequent roof and façade restoration possible.

05 — SCOPE OF WORKS

A whole-building external refurbishment

The roofing works formed part of a broader restoration programme extending from the chimney tops to the external elevations.

Roof + Chimneys

  • Complete roof strip
  • Reclaimed Welsh slate roofing
  • Chimney reconstruction
  • Reclaimed brickwork
  • Lime-mortar masonry
  • Lead hips and ridges
  • Bespoke rooflight construction

Leadwork + Fabric

  • Perimeter gutter reconstruction
  • Central lead gutter
  • Code 5 and 6 leadwork
  • Structural timber repairs
  • Purpose-made joinery
  • External façade preparation
  • Full external decoration

06 — CHIMNEY RECONSTRUCTION

Rebuilding unstable historic chimney stacks

Once full access was available, the condition of the large chimney stacks could be assessed properly.

Significant deterioration within the masonry meant localised pointing alone would not provide an adequate repair.

Defective sections were therefore carefully dismantled before the stacks were reconstructed using reclaimed brick selected to complement the surviving masonry.

Lime mortar was used in keeping with the historic construction, after which the associated roof weatherings could be renewed.

07 — PERIMETER GUTTER

Reconstructing the timber structure beneath the lead

The perimeter gutter was one of the most severely deteriorated components of the building.

Persistent water penetration had allowed widespread decay to develop within the supporting timberwork, making simple renewal of the lead lining impossible.

Large sections were therefore dismantled and rebuilt using purpose-made timber profiles before the replacement weathering could be installed.

08 — CENTRAL LEAD GUTTER

Correcting the geometry before replacing the covering

The large central gutter required alterations to its supporting construction before the new lead lining could be formed.

Falls, bay lengths and interfaces were reconsidered so that the completed gutter could manage rainfall effectively while allowing appropriate movement within the rolled lead sheet.

09 — RECLAIMED WELSH SLATE

Returning natural slate to the historic roofscape

The previous roof covering incorporated concrete interlocking tiles installed during an earlier phase of repair.

During development of the restoration scheme, reclaimed Welsh slate was selected as a more appropriate covering for the age, architecture and listed status of the building.

Suitable reclaimed material was sourced and graded before being installed across the principal and lower roof elevations.

The natural variation of reclaimed Welsh slate allowed the replacement roof to settle naturally into the established city-centre streetscape.

10 — ARCHITECTURAL LEADWORK

Leadwork formed around the geometry of the building

Code 5 and Code 6 rolled lead sheet were used across the principal weathering details according to the demands of each location.

The project incorporated new perimeter gutters, central gutters, flashings, weatherings, hips, ridges and other bespoke details.

Much of the work depended upon the quality of the substrates constructed beneath the lead. Joinery and leadwork therefore progressed as linked operations rather than independent trades.

Where geometry required non-standard components, details were fabricated and adapted on site by Neal Roofing’s specialist leadworkers.

The result is a system designed around both the architectural form of the building and the practical requirement to move rainwater safely away from vulnerable historic fabric.

11 — LOWER ROOF AREAS

Extending the restoration beyond the principal roof

Lower roof ranges around the property were stripped and renewed as part of the same programme.

This prevented the newly restored principal roof from remaining dependent upon adjoining areas that had themselves reached the end of their effective service life.

12 — BESPOKE ROOFLIGHT

A purpose-built feature integrated into the roof

A bespoke rooflight was fabricated and constructed in position as part of the lower roof refurbishment.

Its supporting structure and weathering interfaces were developed as part of the roof construction rather than treated as an isolated proprietary component.

13 — EXTERNAL FABRIC

Completing the restoration below the roofline

The instruction extended beyond roofing to encompass restoration and full redecoration of the external elevations.

Defective joinery was repaired or renewed where necessary before preparation and decoration of the exposed timber components.

Treating the elevations alongside the roof allowed the upper building envelope to be completed as one coordinated conservation project rather than a collection of disconnected repairs.

17 — INDEPENDENT CONSULTANCY

Surveying complex historic buildings

Projects involving substantial historic buildings frequently benefit from professional investigation, specification and contract oversight before construction begins.

Strut Building Surveyors provides independent building pathology, roof condition surveys, defect investigation, repair specifications, contractor procurement and project consultancy.

The consultancy operates independently from Neal Roofing where professional advice or oversight separate from the contracting function is required.

18 — COMPLETION

Restoring a prominent part of York’s historic streetscape

The completed project transformed a heavily deteriorated building envelope while retaining the character expected of a prominent Grade II listed property within York.

Reclaimed Welsh slate, traditional leadwork, reconstructed chimneys and restored joinery replaced a fragmented collection of previous repairs with a coherent weathering system.

Perhaps most significantly, the project demonstrates the capability required to deliver complex heritage roofing where conservation, logistics, temporary works and construction detailing must all be solved together.
