Project Details
Notes from site inspection
Owing to a change in ownership of this magnificent property GNR were contacted to offer advice and costs with regard to replacing the roof coverings.
The roof areas were original to the property and both the slated elevations and lead details associated with the same had reached the end of their useful life.
Moreover, we identified certain areas of repair to the chimney stacks and some remedial work to the timber soffit details was also identified.
Further, one of the main features of the property was two large lead covered bay windows and a door canopy to the front elevation which had previously fallen victim to a cowboy who purported to be able to provide leadwork.
Conclusively, the advice offered by GNR to our client constituted a like for like replacement of all roof areas.
Moreover, we were asked to include the recent extension in reclaimed Welsh slates so that all roof elevations matched.
The Property
Dubbed York’s most expensive house, the property is a fine example of Georgian Architecture.
Constructed in 1858 the property benefits from a former coach house and has been added to over time.
Set in a large garden extending to over 3 acres the house is a rare find in such close proximity to York Centre.
The roof elevations, covered with Welsh slate include lead hips and ridges and a large central lead lined gutter.
The Location
The location of the property is just outside york on one of the main artery roads both in and out of the city.
The house lies to the North of York city centre.

- Replacement of the existing slated elevations on a like for like basis using second hand Welsh slates.
- Replacement of associated lead details and flashings inclusive of a large central gutter and joinery elements to facilitate the same.

The Materials
Reclaimed Welsh slates were carefully sourced from local suppliers to complete the project.
Code 3 and 5 lead were used to execute the detailing to various gutter, flashings and flat roof areas.
A range of treated softwood timber including battens and sections for isolated repairs.
New cast aluminium guttering was sourced with new rafter brackets. Further, new cast aluminium fall pipes were also fitted.
Both quilted and rigid Insulation products were used based upon the merits of each roof area.
As a matter of course, where reclaimed roofing materials are used our go to supplier is The Reclaimed Company.

The project required a full perimeter access scaffolding with stair tower and loading bay to safely distribute materials around the roof slopes.

Project imagery
The bay windows to the front elevation provided a main focal point when approaching the property. As such, they required specialist attention to form a warm roof construction and the lead detailing needed due care and skill.
Concealed outlets and box gutters to the rear of the bays helps manage rainwater and the capping above the entrance door protects the decorative stone detailing below.
