A man who nailed his hand of the roof of a Coconut Grove home required the help of Miami Fire Rescue Thursday afternoon, and they were forced to conduct a tricky rescue that involved cutting part of the roof away. Rescue crews responded to the home at 2949 Day Avenue and found the man, who had been working on the roof, unable to free his hand from the roof. Fire Rescue Lt. Iggy Carroll said the man was using a nail gun and accidentally nailed his finger to a piece of wood.
