Cladall Roofing (Pty) Ltd, a roofing contractor, ordered 13 000 m² of galvanised IBR roof sheeting from SS Profiling (Pty) Ltd with precise specifications regarding thickness (0.5 mm), tensile strength (full hard industrial strength), galvanisation (Z275), and manufacture according to Mittal standards. SS delivered IBR sheeting that, on agreed facts, failed to meet all of these specifications. After installation, the roof showed defects indicating insufficient tensile strength. Cladall claimed damages for the cost of reinstating the roof and withheld the outstanding balance of the purchase price. SS defended the claim and counterclaimed for the balance, relying on its standard conditions of agreement, which included clauses excluding liability, requiring timeous notice of defects, and prohibiting withholding of payment.
