I was just in the roof space (before the heat) and noticed that up at the apex the corrogated sheeting (colorbond custom orb) the edges of undersides down for about 50mm, are starting to show signs of rust & white powder?
what service life is normally expected from this type roof? I know the house was built in 77, so already the roof is approx 28 years old.
I was thinking of wire brushing the apparent corrosion then spraying with a zinc rick paint. Is there anything else I could do?
Looking forward to any suggestions or comments. Thanks
On the Lysaght web site I just found tech bulletin No 2 which tells me how to paint existing product. (should've look there first) I'm still posting this thread as it might interest someone else.

I know that life of roofing is subject to the conditions prevailing but it would be intersting to have comments from others.
look forward to your response
