Article was about half a metre in depth , particularly against the south facing wall of the house at the northern end of the veranda . Fortunately the roof beams are extra size ! I discovered a minor leak in the family room as water seeped through a cracked roof tile through the sarking and batts . Hail banked up on our flat front veranda roof to some depth as the roof gutters were full of hail . My work shed which has a flat galvanised corrugated roof was severely flooded as water poured through the sheeting overlap across the centre of the roof and flowed through the ceiling .
Neighbouring properties suffered significant water damage in situations where their roofs had valleys as part of their structure .
It appears that the hail banked up in the valleys , particularly on west facing slopes , causing rain water to overflow the sides of the valleys into the roof spaces .
Damage to vegetation was extreme . Many trees , both native and exotic , had most of their leaves shredded leaving a carpet of leaves on the ground . We lost all our grapes , a lot of the peaches and figs . All the vegetables were destroyed , particularly the tomatoes . The only plants to survive virtually undamaged were the rhubarb !
