What should the gradient fall be when installing rainwater guttering?
Gutting is installed to ensure any water falling from the roof is safely collected and deposited away from the property. This means the gutter run has to include a downward slope to allow the water to run effectively through the system. The correct downward gradient is either 1cm in every 3.5m, or 1:350.
