Concrete tile, terracotta and Colorbond all age differently in South Australian weather. Here is the real lifespan of each.
Adelaide's most common original roof. Concrete tiles crack, glaze wears off, and the pointing fails. By 30 years most are due for replacement.
The tiles last, but the ridge pointing and sarking do not. A terracotta roof can outlive its own structure.
Genuine BlueScope Colorbond carries a 25-year warranty and routinely serves 40 to 50 years in Adelaide conditions. See Colorbond roofing.
Recurring leaks, crumbling tiles and sagging are the real tell. Check the 7 signs your roof is done.
