I would close the roof up as we could get frost and/or a very wet autumn and that could rot the fruit. Just put some green ones in the freezer, so you have something, give the plants one last decent water and leave them to it.
Or you could put them in a tray, run a cloth under them, then run the cloth out the side and into a water source. You can buy this sort of watering kit, but a homemade version works OK. Just make sure the water is high enough up that it does wick across to the plants. They shouldn't get too wet with just a bit of watering from below. The water will run out, but by then hopefully the fruit will be pretty well ripe and should hold on the plant for a bit.
There is no guarantee, but you have a fair chance of coming back to red fruits
