The roof deck is considered fragile in areas due to water ingress and is therefore to be removed and replaced.

Ridge and Partners LLP consultancy firm conducted a survey and have identified the appropriate roof to be a new Alumasc flat roofing system, including insulation, membranes, trims, upstands, abutments, outlets and accessories, is to be installed to provide a complete warranted system. Associated works include replacement of affected fascia and soffit boards, lead repairs, rainwater goods, and temporary removal and reinstatement/replacement of roof tiles at pitched roof abutments to achieve suitable upstand details.
The contract is to be administered under the JCT Minor Works Building Contract with Contractor’s Design, 2024 Edition. The contractor is required to satisfy themselves as to the existing conditions, extent of works and site constraints. Particular consideration should be given to safe access and edge protection, structural loading capacity, storage of materials at roof level, roof plant/services, drainage and falls, and maintaining the building weather-tight throughout the works.
