George Brolly & Co (Roofing) Limited, working with fellow NFRC contractor, DM Roofing, undertook this complex refurbishment to the roof on the Isle of Bute Discovery Centre.

The project involved stripping and re-roofing of the existing terrace area of the roof and overlay of the complex dome and barrel vault section and existing clerestory windows between the two areas needed to remain in situ, which meant a challenge to form a proper upstand detail without damaging the windows but, crucially, achieving a watertight roof.

The complex nature of the three separate roof areas of the dome, adjoining vault and lower terrace area had differing specifications, taking into account existing condition and the need to insulate certain sections. The A-listed status of the building meant that the more modern approach to apply liquid coatings to every difficult detail was not favoured.

The roof was installed during the winter months, posing all the challenges associated with a coastal exposure site.

The judges said: “The resulting finish achieved is impressive and showcases what can be achieved using high quality RBM products, and what can be achieved when two (specialist NFRC) roofing contractors work together.
