Case Study: Thomas Point Lighthouse

This project highlights metal roof preservation at Thomas Point Lighthouse, one of the most photographed lighthouses in the country. This National Historic Landmark is located in the Chesapeake Bay near Annapolis, MD.

A custom HP-2 Roof Restoration System was engineered for the metal roof of this lighthouse, taking into consideration the corrosion environment, condition of the substrate, and final desired appearance. Initially the surface was primed with HP-7000 Direct to Metal Primer to prevent rusting of the metal roof. This was followed up by an elastomeric coatings system that incorporated HP-1000 and HP-5000 elastomeric roof coatings. On transitional areas, Poly-1 was embedded in these elastomeric coatings to provide reinforcement.

Thomas Point Lighthouse demanded a high performance finish that would not sacrifice color with age. To provide this finish, Acrymax AF-5500 Fluoropolymer coating was selected to complete the project. The desired finish colors were a bright red on the main roof and a deep-toned black on the cupola.
