Since we moved in starlings have always nested under the tiles however this spring they have managed to work their way into the loft. I am on having the tiles refitted by a roofer and the cement reworks so there is no gaps plus install an eaves comb filler. Question is after doing all that will this gap in the picture give them access directly into the eaves and therefore the loft? What is the best way to fill this gap, it's about 20cm long and 4cm gap at its biggest end.
Thanks
