Built in 1420, the Grade I listed Llewn Celyn Hall, which is set in Brecon Beacons National Park, is considered by CADW to be one of the best surviving hall houses in Wales. However, the building had become dilapidated and in 2007 the Landmark Trust began raising £4.2m, including £2.25m from the National Lottery Fund to restore the building into an educational and exhibition space.
Rowlands Roofing were tasked with removing the existing random diminishing stone tiles to allow major roof and structural repairs, before a sympathetic reinstatement of the existing tiles and sourcing matching tiles from a local quarry.
What Rowlands Roofing says
The apprentices were able to gain valuable experience of using stone tiles fixed on Cleft Oak Lath on elevations where the ceilings were exposed, as well as working on the rare Welsh Open Valley detail.
The team recorded and stripped the tile courses, with good stone tiles sorted for size and graded. The battening was a mixture of softwood and cleft oak in areas where the rafters were exposed. The sympathetic replacement of existing stone tiles required a meticulous approach to achieve an even course.
As can often be the case with these projects, sourcing enough reclaimed stone tiles for the remaining roof area was a challenge. Therefore, the team had to work with the local quarry to the new stones were cut to size and dressed in order match for the existing roof tiles. Because the site was exposed, Rowlands Roofing used BS 5534 to calculate the correct head-lap and side-lap.
