Regular claims seem to be down at least 50%. I think this is caused not only from the switch to a named peril policy, but also due to 1% deductibles and ACV policies. I still see a few $500 deductibles, but most are 1% or more. When you combine a $2000 deductible with an ACV policy, on a ten + year old 3-tab roof, no one is happy.
The only odd water related item I can think of is the increasing number of toilet water supply line losses where the white plastic nut cracks, flooding the house.
