The Project

The 475m2 roof of this Grade II listed property was previously finished in grey Ffestiniog natural Welsh slates with feature bands of heather Penrhyn Welsh slates, however budget constraints required us to source a more cost effective alternative which would also meet the stringent requirements of the local authority's Conservation department.

Cembrit-Blunn Glendyne (grey) and Trinity (purple) natural Canadian slates were therefore suggested and samples were approved by The Vale of Glamorgan council. As they were to be laid alternately in bands of four courses to match the existing roof, close attention was required at hips and valleys to ensure that the banding lined through as best as possible, due to adjacent roof pitches differing.

Proctor's Roofshield breather membrane was utilized in order to remove the requirement for unsightly ventilation measures which would have impacted on the Listed Building Consent. The existing clay roll-top ridge tiles were re-used as far as possible in order to further reduce the visual impact of the finished roof.

Our contract also included the removal of the existing inadequate rainwater disposal system and replacement with an upgraded cast aluminium system. Due to the large roof elevations and steep pitches, project specific rainwater calculations were carried out to ensure that the new system was appropriately sized.

The work was completed in 7 weeks (included erection and removal of scaffolding), with a final account value in excess of £50,000.

This contract won the N.H.I.C. Excellence in Roofing award 2008 and received a commendation in the 2008 N.F.R.C. annual slating award.
