Measure the rainfall and note the flow rate. Change the size of the rainwater goods to suit the flow rate. The pipe diameter is determined by the area of roof drained [Ruberoid Guide to Flat Roofing]. If the fall is inadequate, hack off the slabs and lay them to a minimum of a fall of 1 in 50 [Draft Code for waterproofing of Reinforced Concrete Buildings] to ensure the water does not stagnate on the roof and can drain off to the outlets.
