bad corrosion on zincalume gutter

It is a waste of time and money choosing zincalume over colorbond guttering.

I have a ‘thing’ against trying to save money on guttering materials.

I am referring to the practice of specifying zincalume gutters instead of colorbond guttering. Sure there will be a price savings between the two – but at what cost?

There is no question that colorbond gutters last longer than zincalume ones. How much longer, I can’t tell you…. But what I can say is that I have pulled out far more rusted zincalume gutters than rusted colorbond guttering over the past decade or so.

And the cost to replace guttering is not cheap.

Typically, a suburban residential roof will have about 50 to 60 metres of guttering and cost around $3000 to replace properly. The material component of the price for replacement guttering to a typical house is quite small. It is the labour that is expensive.

With a price difference of about $1.50 between colorbond and zincalume guttering – you pay only $85.00 extra for choosing colorbond guttering.

With the additional cost of  colorbond fittings, the total price difference to the gutter installer is only about $150.00.

So, if the choice is between $3000 for new  zincalume guttering and $3150 for new colorbond guttering… I know which one I will be choosing!

…It is what is called a “NO-brainer”. The small extra price that you pay for choosing colorbond guttering will repay itself year after year because of the extra durability of colorbond guttering.

And I have not even mentioned the “free” gutter paint job that you receive if you choose colorbond guttering!

I recently had a look at some rusty guttering in an Inner Western Suburbs home in Sydney and the video below shows what I mean by wasting your money on zincalume guttering…

zincalume guttering is a total waste of time in my opinion!

I am currently working on a project in the Pacific, providing rainwater to communities that are within 100m of the ocean. People point out examples here of colorbond rusting where zincalume hasn’t. ANy ideas as to this?? (I have specified colorbond and am worried because locals are saying it is the wrong spec)
