Holt Farm: Safe Work Access to a New Roof

Covering an area of nearly two acres (7,600 m2), the Holt Farm dairy complex includes two large and three smaller cattle buildings used for milking, housing, feed storage, offices, and viewing gallery. The complex typically houses 240 dairy cattle, yielding an average of 7,500 litres per year that is supplied to a nearby dairy processing facility. Holt Farm’s dairy complex is L-shaped with five interconnecting ridge-roofed buildings that create four internal valley gutters. The original fibre cement roof with badly yellowing old-style roof lights had deteriorated and suffered storm damage; the owners decided that a cost-effective new roof was required.
