Saint Mary's Roman Catholic Church was designed by architect P. J. Dodd at the end of the 19^th century. Over the years we have provided architectural and conservation services for the parish and the church. In 2017 we provided architectural and conservation services for the repair of the semi-circular apse roof at the south end of the church. 

The roof of the apse chapel was leaking and had caused some damage to the linings and elaborate decorations internally. The prevailing wind was causing uplift of the existing slates which were poorly fixed. Patch repair work had occurred over time, however the success of these works was limited.

The project involved stripping off the existing roof slates and lime parging to install a breather membrane and relay existing slates where possible and replace with Blue Bangor slates to match existing where required. The existing close boarding beneath the slates was retained and conserved in place. The works were carried out by Mr John Hough, J.H. Access & Maintenance Solutions.
