Concrete tiles are currently the most economical means of providing a pitched roof over a dwelling. The timber truss roof structure for the application of concrete tiles can be relatively light.

Clay tiles are an expensive material, and are selected for aesthetic attributes, or where existing buildings with clay roofs are altered or extended.

Slate is durable and has inherent aesthetic qualities. It is considerably heavier than the concrete roof tile and requires a more substantial roof structure.

Fibre cement slates or shingles are manufactured from fibre cement and are supplied in a number of different colours. This material is light-weight and suitable for re-roofing, for example, corrugated iron roofs which have not been constructed to take the weight of the heavier slate, concrete or clay tiles.

Profiled steel sheeting, manufactured in South Africa from a number of different materials such as galvanised sheet steel, stainless steel, aluminium and zinc, copper and "chromadeck" (corrugated iron sheeting). This is best suited for industrial and retail buildings.

Water ponding on a flat roof system will increase the rate of roof wear and the chance of leakage. Drainage and evaporation of any water should occur within a day of a rainstorm. Whenever possible, measures should be taken to reduce any significant ponding. In some cases ponding may cause or be the result of roof framing settlement. When the surface of a flat or slope roof is worn and requires replacement, the existing roofing material in most cases should be removed down to solid decking.

Because the design of this type roof usually restricts visibility of structural members, removal of the surface is the only opportunity you have to check the condition of the roof framing. Removal of the old, worn surfaces will also increase the life of the new roofing. Wherever water has ponded for any length of time, you can also find deteriorating, rotting felts. In addition to the action of the water causing the bitumen to liquefy, the presence of industrial wastes that collect on the roof will mix with the water and turn it into a chemical solution. The bitumen and felts are eaten away rapidly, disintegrating the roof. Ponding water has a remarkable way of finding its way into and through a roof. An easy way to prevent leaks is by keeping your drains clean and using a waterproofing product that will tolerate ponding water.

Please be warned that inexperienced and amateur attempts to repair your roof with incorrect procedures or materials could cost you dearly, and possibly force you to re-roof.
