There will still be finer tree roots under the lawn. Just wait until the grass is dry and use a stiff broom, knock them down and sweep them off (add to compost heap).
They really are doing no harm - in fact they're a sign of the rich ecological diversity in your garden. A good thing.
They'll disappear anyway when the weather dries out.
