Roofshield used as the premier choice for royalty

Roofshield from A. Proctor Group has been selected to provide superior quality protection to Hillsborough Castle in a £20 million programme of works.

Historic Royal Palaces set out works comprising major renovations, the addition of two new visitor centres and a host of smaller operational buildings.

Penrose Roofing 2014 were awarded the roofing contract including all lead work and rainwater disposals. The contract comprised 13 individual roofs, with the primary coverings ranging from new Welsh Natural Slate, Canadian Glendyne Natural Slate, and with some roofs stripped re-using the existing natural slates, making up the shortfall with salvaged Welsh Slate.

Architects, Consarc specified Roofshield, a pitched roof underlay, to be fitted to a total of nine of the roofs, including five newbuilds and four existing. The largest of the roofs was the Lower Visitors Centre, which consisted of a newbuild joining to existing buildings, all within the original inner wall area.

Many vapour and air permeable underlays use an airtight VP film layer to achieve their performance, whilst Roofshield’s Spunbond Meltblown Spunbond (SMS) structure allows high levels of airflow, in addition to the transport of moisture vapour, making the formation of condensation in the roof space virtually impossible.

It has an extremely high degree of vapour permeability, as well as air permeability, so will still perform in conditions in which airtight alternatives will not.

The high performance of Roofshield, backed by two BBA certificates, has been successfully used in preserving and protecting the fabric of a wide range of historic and listed buildings for nearly 25 years.

Gordon Penrose, managing director of Penrose Roofing, said: “Roofshield was chosen by the architects who have successfully used it on several projects. It has also become our preferred choice of a pitched roof membrane and has been excellent to work with. It is exceptionally strong, durable and its superior air permeability ensures comprehensive protection for historic buildings.

“Another key feature is that Roofshield is available in one-metre rolls, which makes it much easier to handle and work with on-site, particularly in windy or breezy conditions.”
