SIGA Heritage – Cotsway

Project Name: Trowbridge County Hall
Slate Supplied: SIGA Heritage, Cotsway
Main Contractor: Steele Davis
Roofing Contractor: Roundway Roofing

Trowbridge County Hall is a Government Building which is used as the offices of Wiltshire County Council – a council formed in 1889. The building was built in 1940 having been designed by P.D Hepworth, who was believed to have been inspired by a building in Amsterdam.

The building’s existing roof had original roofing stone, which was causing continuous maintenance issues and requiring repairs. The original plan was to replace the roof with a natural stone, but due to cost implications, an alternative was necessary. After the Roofing contractor, Roundway Roofing was presented with SIGA Heritage Cotsway slate it was chosen and approved by the local authority as the client.

All contractors were happy with the proposed slate due to its overall appearance, originally demonstrated by the samples/case studies provided, as well as the warranty options available.

The job did have one special consideration, which was resolved by the SIGA Heritage representatives; the existing building had original swept valleys.

This meant an on-site schedule had to be implemented to produce a production swept valley. Once this had been completed, the job was completed smoothly, within time and budget.

After completion the contractors were pleased with how it went – despite SIGA Heritage slates are laid in diminishing courses, it was a relatively straight forward slate to lay and create the required roof scape.

The client was similarly delighted with the job as the SIGA slates were able to recreate the look and feel of the previous roof, whilst preserving its heritage.
