HDLPC members review alternative roofing, decking and tile samples for historic properties
Summary
Commission member presented sample materials—composite tiles, paintable porch decking and upcycled decking brands—for consideration in material‑substitutions guidance; commissioners discussed durability, cost and compatibility with historic district approvals.
A commission member presented samples of alternative materials for roofs, porches and decking, and commissioners discussed their potential use as approved substitutes in the historic district.
The presenter described mock terracotta tiles offered by a supplier (sample packet provided) and asked whether such products could replace specialty terracotta roofing. Commissioners noted uncertainty about longevity and potential installation constraints; one commissioner observed that replacing an entire roof may be necessary rather than patching with mismatched pieces.
The presenter also showed composite porch decking samples from manufacturers identified as Modern Mill, TimberTech and a paintable composite (referred to in the presentation as Eratus/Iratus). The presenter said some products are paintable and breathable, and that at least one brand has been used in National Park Service‑approved projects, which may make them a viable path for approvals. He emphasized cost and installation differences compared with traditional materials and suggested the samples be circulated to the material‑substitutes working group for further review.
No formal action or decision was taken; the item was treated as a show‑and‑tell and left for further consideration by the working group.
