We were awarded the contract to re-roof the Engine House of the Mill, which due to a rotten truss ends, was in danger of collapse. The works included complete timber repairs and restoration of the lantern.
The original cast iron gutter was removed as it had failed.
The roof had a welsh “tonne” slate fixed directly to a sarking board. The slates were stripped and stacked inside the mill building. As the slates were diminishing course we sorted and stored in size order.
Our joiners constructed the new stepped parapet gutter which was lead covered. The subframe and “penny boarding” with lead rolls was installed. A Tri-Flex lining was applied to the gutter to make it water-tight. After this was completed our roofers dressed and tidied the previously stacked slates ready for the slating.
We installed around seven tonnes of lead on the gutter with flashings and an area of cladding. In our workshop we made three new large lead outlets with overflows along with fifteen code 8 roof vents. Most of the leadwork was completed at the mill, with the lead vents and parts of the outlets being lead welded on site.
The lantern was reconstructed with new lead and glazing installed.
The scaffolding for the project was complex as it had to allow our personnel access to the full height windows so they could restore them, while still allowing access for removal of asbestos beneath and ensuring the steam engine was fully protected from any damage. It was also a challenging site to manage as the factory was a live site with various activities taking place that had to be accommodated.
One of the aims for the Mill was to have some space for community use and heritage and art spaces. Our work ensured that the roof did not collapse and that the character of the mill was not changed. We feel it is very important that the original features and feel of a building is retained. We are very considerate as to how we restore buildings and work closely with Conservation Officers.
