A little Kiwi trick to get a couple more years out of a corrugated iron roof: If you're like me you'll have several tins of paint with an inch or two in the bottom that you know you're never going to get around to utilising.
You'll also have some old roller blinds, an old canvas tarp, or similar heavy material lying around in a corner somewhere.
Give the area where the leak is a coat of paint, stick a patch of the material over it, another coat of paint straight away, and you've got a few more years life out of that roof.


(Don't thank me. Just buy me something small and expensive and park it in my driveway.)
