Roofing materials are supplied by profile, gauge and coating to suit span, pitch and exposure conditions, together with flashings and fixings. Procurement should define the required material/form, end use and acceptance basis rather than rely on a broad roofing & cladding label.

Project use and material form

The listed applications are Commercial and industrial buildings, Residential roofing, Institutional and school buildings and Agricultural and storage structures. State the actual substrate, process, project location or finished article because it determines the relevant grade, dimensions, finish and performance criteria.

Those fields vary by source or configuration; any test report, datasheet, certificate or sample needed for approval must be named in the enquiry rather than assumed.

Define unit size and quantity basis, protective packing, labels and batch/lot traceability, pallet or bundle limits, moisture/temperature or hazardous-goods controls where applicable, unloading method, storage and phased site or production delivery.
