Hi, we had this patio put in a few months ago and it was built overhanging the roof a bit. There is a gap between the roof and the patio and we've only just now had rain heavy enough that I've noticed that the rain splashes off the roof tiles/solar panels onto the area below. How can I prevent this/install something to block the rain in this section. It seems to only be in the section where the solar panels are, the rest of the overhang area along that side seems to be ok.
