While a galvanized corrugated roof might final 20 years, a Colorbond roof would have a fifty calendar year lifestyle or for a longer period.
Terra cotta tiles are also a choice; they literally final permanently. Imagine archaeological dig. You’ll find examples of terracotta roofing that were about for 1000s of several years. Having said that it is actually about double the cost of a concrete tile roof.
For our uses, We’re going to Examine concrete roof tiles and Colorbond roofing, and can focus on Melbourne disorders. Both equally solutions do an admirable position at the things they’re made for (keeping the weather conditions out). Concrete roof tiles have been Employed in Melbourne for at least seventy five yrs and there are various houses in older suburbs for instance Heidelberg and Camberwell that still have their primary concrete tile roofs.

Also they have an inclination to keep Filth, dust and coloured concrete solutions so forth which washes into the drinking water tank. In the course of the latest 10 calendar year drought in Melbourne, home proprietors were inspired to collect rain drinking water for home use. This affected the desire for Colorbond roofing.
