The Batemoor Estate in Sheffield incorporates a mixture of single and multistorey properties which were originally constructed over 40 years ago. As part of the local authority’s city wide renovation programme, the existing asphalt flat roofs on 14 of the larger buildings were to be upgraded. The cost of patch repairs to each of the 500m2 roofs was becoming increasingly expensive each year, and the existing drainage system was also prone to regular blockage. In addition, the thermal performance of the roofs
needed immediate improvement.
