National Register of Historic Places Program: State Historic Preservation Officers (SHPO)
The National Register of Historic Places is the official list of the Nation’s historic places worthy of preservation. Authorized by the National Historic Preservation Act of 1966, the National Park Service’s National Register of Historic Places is part of a national program to coordinate and support public and private efforts to identify, evaluate, and protect America’s historic and archeological resources. State Historic Preservation Officers (SHPO) play a critical role carrying out many responsibilities in historic preservation. Surveying, evaluating and nominating significant historic buildings, sites, structures, districts and objects to the National Register is one such key activity. To help find out if a historic place meets the National Register criteria and how the nomination process works in your state, contact the appropriate SHPO below for assistance.

State Preservation officers will be able to inform you of any tax credits available in your state. Some states offer as much as 25 % in tax credits to homeowners, for work performed in designated Historic Areas. This includes slate roofing. Additionally, cities and counties may offer tax credits in addition to the state. These avenues should all be explored, to give your slate customer every opportunity to keep their slate roofs. Other states offer tax credits only on commercial buildings that are restored to preservation standards.
