01 — THE PROJECT

A small but intricate roof in the heart of historic York

Neal Roofing was instructed to replace a distinct roof area to a historic property on High Petergate in York city centre.

The work required traditional slating using second-hand Welsh slate together with specialist leadwork to gutters, gable interfaces and other weathering details.

Its central location, close to York Minster, meant the completed work needed to remain sympathetic to the surrounding historic roofscape while also addressing practical issues such as tree debris, maintenance access and vulnerable masonry.

PROJECT

Roof Restoration

PROGRAMME

Circa 4 Weeks

LOCATION

High Petergate, York

PRIMARY MATERIAL

Welsh Slate

02 — LOCATION + CONTEXT

Roofing within York’s historic core

High Petergate forms part of the historic route through central York and sits within one of the city’s most architecturally sensitive areas.

Roofing work in this location demands particular care because new materials and details are seen in the context of neighbouring historic buildings and the wider city roofscape.

The project was therefore approached as a conservation-sensitive roof repair rather than a generic replacement exercise.

03 — PROJECT REQUIREMENTS

Traditional materials with practical improvements

The roof area required replacement using materials appropriate to the existing building.

Second-hand Welsh slate was selected for the principal covering, maintaining the traditional appearance while allowing the roof to be reconstructed on new battens and breathable underlay.

The lead gutter linings were also redesigned to improve capacity and make future maintenance easier in a location affected by overhanging trees.

Welsh Slate

Second-hand Welsh slate reinstated to preserve the character of the historic roofscape.

Lead Gutters

Gutter linings enlarged to improve capacity and simplify ongoing maintenance.

Gable Protection

Lead detailing introduced over vulnerable coping masonry to reduce future saturation and decay.

04 — SCOPE OF WORKS

A compact roof requiring careful detailing.

Although relatively small in area, the project required both traditional slating and specialist leadwork to resolve several important interfaces.

Roofing Works

  • Removal of existing roof covering
  • Inspection of supporting construction
  • New Proctor Roofshield membrane
  • New treated timber battens
  • Traditional re-slating
  • Second-hand Welsh slate

Leadwork + Interfaces

  • Replacement lead gutter linings
  • Increased gutter capacity
  • Code 3 and Code 5 lead
  • Gable coping protection
  • Lead weathering details
  • Maintenance-conscious detailing

05 — SECOND-HAND WELSH SLATE

Maintaining the character of the city roofscape

Second-hand Welsh slate was used to reconstruct the principal pitched roof area.

Reclaimed Welsh slate is particularly suited to historic buildings where the texture, colour variation and weathered appearance of the finished roof are important to the architectural character of the property.

The slate was installed over new treated battens and a Proctor Roofshield breathable membrane, combining traditional external materials with a modern supporting build-up.

06 — LEAD GUTTERING

Designing for leaves, debris and future maintenance

Overhanging trees created a practical consideration for the rainwater system.

Rather than simply reproducing the original gutter arrangement, the replacement lead linings were increased in size to provide greater capacity and improve access for routine cleaning and maintenance.

This illustrates an important principle in roof restoration: traditional appearance does not prevent sensible improvements where they can be introduced without harming the character of the building.

07 — GABLE WEATHERING

Protecting vulnerable masonry from continued saturation

The existing gable coping had suffered from persistent moisture exposure, with vegetation becoming established within damp sections of masonry.

A lead weathering detail was introduced over the coping to reduce further direct water penetration and protect the masonry below.

The intervention was deliberately simple but addressed the underlying mechanism contributing to deterioration rather than repeatedly repairing the symptoms.

12 — INDEPENDENT CONSULTANCY

Surveying historic roof defects

Historic buildings frequently require careful investigation before deciding whether isolated repairs or more extensive roof replacement is appropriate.

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

13 — PROJECT OUTCOME

A sympathetic roof restoration in the shadow of York Minster

The completed project retained the traditional character of the High Petergate property while resolving a number of practical weathering and maintenance issues.

Second-hand Welsh slate provided an appropriate principal covering, while enlarged lead gutters improved rainwater management and future maintainability.

The additional gable coping detail addressed a specific source of masonry saturation and helped protect the historic fabric from continued deterioration.

Although modest in overall roof area, the project demonstrates the level of detailing often required when working within York’s historic built environment.
