REPAIR AND MAINTENANCE OF FLAT ROOFS

The repair and maintenance of flat roofs probably creates one of the greatest headaches for a property manager as well as giving a touch of migraine to the professionals and advisers concerned with flat roofing problems. It was probably 15 years ago when we all became aware of the failings in design, construction and maintenance of flat roofs erected in the mid‐sixties and early seventies. The Codes of Practice at the time informed us that flat roofs, if designed and constructed in accordance with the Codes, should be maintenance‐free! Unfortunately this was not the case. Flat roofs, even today, still remain unmaintained with maintenance only being considered when failure actually occurs, when something has to be done. This attitude and approach are changing and today property managers are very much more aware of the importance of keeping flat roofs maintained and in a good state of repair. The property manager can also take comfort from the vastly superior materials that are available on the market now as opposed to ten to 15 years ago. This, however, is not an excuse to become complacent about the obligations of maintaining flat roofs, indeed there is no less obligation now than there was ten years ago; the due process of maintenance must be followed. Maintenance of flat roofing should form part of the designers thinking when detailing and specifying a roofing system. Unfortunately, it is not always possible to achieve maintenance input in terms of design and specification. Consequently, maintenance for flat roofing is only considered on completion of the roof and it is at this stage that maintenance policy must be formulated.
