Just asking as I can't seem to find any videos on this topic. Fitted metal copings to flat roof parapet. Where the coppings meet the wall I chose to finish it with lead. Is this the correct way to dress the lead to this corner by cutting a small triangle at the top where the chasing is where the corner is just so I can fold the lead and sit it in the chasing, then cut across horizontally.
Not a roofer or lead worker
