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
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
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.
