When lightning strikes, it chooses the fastest path to ground. For that reason, lightning is typically striking the highest object in an area, regardless of that object's composition. While metal conducts electricity, it does not "draw" lightning. Documents put out by the Metal Construction Association and other groups, as well as numerous magazine articles over the years, have concluded that there is not an increased risk of lightning strike with a metal roof. If the house is the highest object in an area, then it is at risk of a lightning strike and it makes no difference what type of roof it has. It is wise in all cases, though, to make sure that all plumbing pipes and electrical conduits coming through the roof meet current building codes and are non-metallic. That way, if the home is struck, there is little chance of the charge being carried into the structure. If someone chooses to have a metal roof grounded or have lightning protection installed, that can be done through any qualified lightning protection contractor.
