Have just bought two metal sheds and could not use conventional guttering systems without voiding my warranty. Despite reading that the Halls Rainsaver required a roof of a certain thickness in order for the brackets to clamp I tried them anyway. Perfect, they do work on metal sheds as long as the plastic finishing strip for the roof line is used the brackets will clamp around nicely. Sheds in question are the ‘Billy Oh Carrington’ and the ‘Billy oh Beeston’ from Garden Buildings Direct. I have no experience with any other make. The flexypipe downpipes have also proved to be worth their weight in gold as I was unable to go straight down to the water butt. These can be found in the ‘spares’ section. Once purchased delivery was very efficient. Job done!
