The most common type of roofing used in Auckland houses is galvanised or coated steel, followed by coated metal and concrete tiles.
Some maintenance tasks are common to all types of roof; others are specific to the particular roof type. Some tasks will need to be completed more often if you live close to the sea or in a geothermal area. Flashings may not last as long as the roof so they will require more maintenance. Anything that penetrates the roof, such as pipes, flues or fixings, needs special care to ensure weather tightness.
