We have birds building a nest in our roof, due to one of our tiles becoming dislodged and leaving a hole. The obvious answer is to get the tile replaced, but how do I make sure we don't lock any birds in? Also, will the eggs have hatched yet?
Why not make a temporary barrier with some wire netting. If the birds are still in there, it's an easy job to lift the wire netting , & letting the birds escape. Re eggs hatching; i'd be very suprised if any eggs have been laid yet.
Easier said than done unfortunately. It's a three story town house, and the loose tile is near the top of the roof, so it would take a very brave person to try it.
I have since read that there is nothing we can do until they leave in 3 / 4 months, then get a roofer to fix the tile.
