Abstract
Many buildings in the 1960s and 1970s used low-cost lightweight flat roof constructions on deep plan buildings. Such roofs were often constructed with limited design input, minimal specification and indifferent workmanship, which inevitably led to early failures requiring extensive remedial work. This poor performance record produced widespread lack of confidence in flat roofs and increasing interest in the use of pitched roofs. For remedial work, a pitched over-roof was seen as an attractive solution, offering a water-shedding umbrella to replace the failed waterproofing on a flat roof. Over-roofs must be designed to suit individual building requirements, taking account of existing plan form, roof loading, roof structure and covering material, as well as appearance and feasibility of the new construction. This paper illustrates four recent over-roof projects that exhibit specific problems, each requiring a unique design solution.
