The Winchcombe School Roof Refurbishment

Tender description

The existing historic roofs at The Winchcombe School are now beyond their original service life and now leak in various areas. The roofs are asphalt / bitumen finished on a flat concrete slab. One area, the hall, also has a parapet with weir outlets and hoppers etc. Where flat concrete roofs have overhangs and drip details the concrete has failed in places and there is a separate report with proposed repairs. The school has been extended over the years and one unfortunate consequence of this is that a lower-level roof between teaching rooms and ancillary spaces is now within a well (below the main roof) where water can be trapped. It is proposed that this area be revised to have a roof deck at high level reducing the risk of trapped water. New roof lights will also be required in these areas. All existing roofs affected will need to be stripped, new vapour barrier laid, new cut to falls insulation including flat insulation to detailed areas and new bitumen roof finish over. Due to the building being an operational school, some works may be able to be carried out in term time, this would need to be agreed by all stakeholders. The works are to be phased over two years, phase one in 2021/22 and phase two in 2022/2023
