- Box gutters and internal gutters on contemporary designs blocking with leaves and dust and overflowing at the outlet
- Screws backed out on sun-facing pitches after twenty summers of expansion and contraction
- Perished sealant on flashings around skylights, aircon penetrations and solar mounts
- Minimum-gauge sheeting on wide spans flexing and loosening the laps on early builds
- Ponding and blocked drains on the membrane roofs of apartment buildings
Local notes from the roofers
Mawson Lakes is one of the youngest suburbs on the list, developed from the late 1990s on the old Levels campus land, and its roofs are almost all Colorbond in low pitches on two-storey homes and townhouses. Young roofs still fail, and the pattern here is fairly predictable. Box gutters and internal gutters on the contemporary designs block with leaves and dust, overflow at the outlet and put water straight into the ceiling. Screws on the sun-facing pitches have backed out from twenty summers of expansion and contraction, and the sealant on flashings around skylights, aircon penetrations and solar mounts has perished. Some of the early builds used minimum-gauge sheeting and wide spans that flex, which loosens laps over time. The apartment buildings around the campus and the Boulevard use membrane roofs where ponding and blocked drains are the usual complaint. The wetlands and the lakes bring more birdlife and debris onto roofs than the surrounding plains, and the open ground to the west gives the winter south-westerlies a clear run. Body corporate approvals and shared access on the townhouse groups need to be organised before work can start.
