A slate fell off the scaffolding onto a newly laid lead apron , and I only noticed after I have laid a drip bead over the lead and rendered the whole wall that it had pierced the lead . It's not a big hole but obviously I'd like to fix it up the best way . As I've dropped the bead over the turn it won't be easy to replace the lead , I don't really want to patch the hole with flash tape. Is it possible to fill the hole with melted lead ? I've tried looking up online but all I can find is about lead sheet welding . Also the roof the apron is on isn't battened and slated yet but I think the hole would be above a slate not on the drop of the wall .
