Metal Roofing Questions and Answers
Does a metal roof attract lightning?
It would seem to make sense that a metal roof would be susceptible to lightning strikes, but that’s not the case. According to the Metal Roofing Alliance, the opposite is actually true. Metal roofs do not attract lightning anymore than other types of roofing material do.
In the rare case a metal roof is struck by lightning, the roof may actually help distribute the electrical charge from the roof into the ground, which would help reduce the risk of damage. The same can't be said for other roofing materials.
Does my existing roof have to be tore off before installing the new metal roofing?
Because of its lightweight properties, metal roofing can be installed over an existing roof. However, some roofing contractors in Milford, DE may prefer to have the old roof removed to ensure the optimal sheathing and insulation is installed. Your metal roofing contractor will help determine which option is best for you.
