Roofshield® protects the heritage of Northern Ireland Church


The world-renowned Roofshield membrane from the A. Proctor Group is now an integral part of protecting the heritage of St Andrew’s Presbyterian Church, Bangor, and enabling it to continue serving the local community.

The current church building opened in 1957, and as part of a £10,000 Cornerstone grant, the redevelopment works at St Andrew’s will include replacement of the roof, repairs to the heating system, and a building extension.

Architects Knox and Markwell, specialists in church design and conservation projects, will lead the project design. Specialist roofing contractor D. Harkin & Co. Roofing will carry out the roofing works.

D. Harkin chose Roofshield roofing membrane, which has long been recognised as one of the highest performing roofing membrane solutions, providing a pitched roof underlay, which is both air and vapour permeable.

The products exceptional performance has proven itself in the most demanding locations around the world. In addition, its characteristics allow even very complex pitched roofs to breathe without the need for air gaps or secondary venting.

Incorporating Roofshield into the roofing design can lead to savings in labour and material costs due to removing the need for an additional VCL.

The exceptional air permeability performance of Roofshield means that the roof space will result in similar air changes to that of a roof using traditional eaves/ridge ventilation.

A unique performance characteristic of Roofshield is  its patented SMS (Spunbond Meltblown Spunbond) structure, which allows high levels of airflow and the transport of moisture vapour, making the formation of condensation in the roof space virtually impossible. Numerous vapour permeable membranes use an airtight vapour permeable film layer to achieve their performance. However, the exceptionally high degree of vapour permeability and air permeability of Roofshield means that it can perform in conditions in which air tight alternatives will not.
