Protecting historic buildings from lightning damage may require special considerations. For example, the visible components of the lightning protection system have to maintain the look and historic features of the original building, yet meet modern standards for performance. To the extent practical, new lightning protection components have to be installed without damaging historic building materials or the character of the old building.
The National Park Service, as the custodian of many of the historic buildings in the United States, has just published “Lightning Protection for Historic Structure” by Charles E. Fisher, 50th in the Park Service’s Preservation Brief series. The 20 page pamphlet “includes information on the care, maintenance, and repair of historic and older lightning protection systems; discusses factors to consider in assessing the need for a lightning protection system where none exists; and includes historic preservation guidance on the design and installation of new systems.”
