Case Study
St Lukes Church, Southsea

Clarke Roofing re-slated St Luke's Church in Southsea, a Neo-Norman Grade II listed church built of flint and stone. Our carpenters and slaters reshaped the curved Apse roof so it runs into the nave without a step, then re-roofed the entire church in new heather blue Welsh slate from Penrhyn Quarry. This case study covers the roof layout, why the church needed re-slating, the Apse alterations and the finished roof.

Project Overview

St Luke's Church in Southsea is a Neo-Norman Grade II listed building, built of flint and stone with a Welsh slate roof. The roof required substantial re-roofing, and Clarke Roofing was appointed to carry out the works, which our team completed using Welsh slate.

The church roof

The roof of St Luke's is made up of several sections.

  • Aisles. Lower slate roofs on the north and south aisles.
  • Nave. Upper slate roofs on the north and south elevations, each containing five dormer windows.
  • Apse. A curved roof on the east elevation, running into the upper slate roofs of the north and south elevations.

Why the church needed re-slating

The church had been completely re-slated in 1996, reusing the existing sound slates together with approximately 30% new Welsh slates. Unfortunately, the existing slates continued to deteriorate significantly, so the decision was made to re-slate the nave including the dormers, the Apse, the north and south aisles, the boiler room and the south porch roof.

Reshaping the Apse roof

The most complex part of the project was the curved Apse roof, which forms part of the upper roof on the north and south elevations. The existing roof had a step where the Apse met the nave, formed as a verge and weathered with soakers and lead flashing.

Our carpenters and slaters removed the step so that the curved slate roof of the Apse now continues across the nave elevations without a break.

Re-slating in Penrhyn Welsh slate

Once the alterations to the Apse roof were complete, the entire church was re-roofed in all new heather blue Welsh slate from Penrhyn Quarry. Welsh slate is one of the best roofing slates available, and its high resistance to acid and other chemicals makes it extremely durable. Find out more about our slating work.

Project Outcome

The scaffolding came down in February 2022, leaving St Luke's with a complete new Welsh slate roof and a continuous curved Apse. The accompanying photographs show the attention to detail carried through every stage of the project, and everyone at St Luke's said they were thankful "to everyone who has done an amazing job over the last 6 months".
