Using TLX Gold in a Church Roof

Using TLX Gold in a Church Roof

The church of St. Michael and All Angels in the village of Witton Gilbert dates from the late Norman period. A Grade II listed building, it is constructed of sandstone, with stone gable copings and a roof of Welsh slate. Re roofing has been carried out at various points in its history thanks to the generosity of benefactors; in 1484 it was the Prior of Durham, in 1625 the Dean of Durham. There was a new roof in 1860, and in 2013 the benefactor is English Heritage, who have contributed towards the £96K cost.TLX Gold draped with exposed rafter

The Problem: The roofers found that as the slates were removed the lath and plaster came away, so only the rafters themselves remained intact. Conventional insulation board solutions were simply not workable, as this would not only be unacceptable to English Heritage in terms of the historical authenticity of the structure, but any significant increase in roof height was not possible given the positions of the existing guttering and gables.

The Solution: Using TLX Gold above the rafters provided not only insulation, but also waterproofing by virtue of its integral breather membrane. The rafters were counter battened with 38mm battens and the TLX Gold was draped across them, with the slates being replaced on the tiling battens. Overall the roof height was increased by only the height of the counter battens, which was deemed acceptable by English Heritage. The interior appearance of the roof was preserved with the exposed rafters as in its original construction.
