A. Roofs
3. Repair or replace roof details (chimneys, roof cresting, finials, attic vent windows, molding, bargeboards and other unique roof features). Use some of these details in designing new buildings.
4. Materials used in roofing existing buildings or new construction shall duplicate the roofing materials originally found in the neighborhood. Asphalt or fiberglass shingles can be appropriate, as are wood, slate, standing seam metal, or metal shingle or tile roof coverings. The color of roofing materials should be a dark green, charcoal gray, black or dark reddish brown to simulate the original roof colors.

B. Windows
1. Original windows shall be reused if possible. It will be much less expensive and much better historically to retain the original windows, and it is inappropriate to replace them with new windows that differ in size, material or pane division.
8. Reuse existing, serviceable window hardware.

E. Wood Wall Coverings
3. Replacement siding must duplicate the original. Trim and patterned shingles that must be replaced must also duplicate the original material.
5. Wooden features shall be repaired by patching, piecing-in, or otherwise reinforcing the wood. Repair may also include limited replacement with matching or compatible substitute materials, when elements remain and can be copied.
6. Wood features that are important in defining the overall historic character of the building shall not be removed.
7. Replace only deteriorated wood. Reconstructing in order to achieve a uniform or "improved," "new" appearance is inappropriate because of the loss of good historic materials.
8. An entire wooden feature that is too deteriorated to repair or is completely missing shall be replaced in kind. If features are replaced, the materials they are made from shall be compatible with the original in size, scale and material. Replacement parts should be based on historical, pictorial and physical documentation.
11. Retain paint and other coats that help protect wood from moisture and sunlight. Paint removal must be considered only where there is paint surface deterioration and as part of an overall maintenance program which involves repainting or applying other appropriate protective coatings.

F. Masonry Wall Coverings
4. Identify and preserve masonry features that define the historic character of the building, including walls, railings, foundations, chimneys, columns and piers, cornice and door and window pediments.
7. Match replacement mortar to the original mortar in color, composition, profile and depth. If necessary, analyze the original mortar to determine the proportions of lime, sand and cement. A "scrub" technique shall not be used to repoint. The width or joint profile shall not be changed unless the change will return the joint to its original appearance. Sound mortar should not be removed.
8. Never repoint with mortar of high Portland cement content, unless that is the content of the original mortar.
9. Historic masonry shall not be coated with paint, stucco, vapor permeable water-repellent coatings or other non-historic coatings.
