Slate Projects in Washington, D.C.

Produced by natural geological forces over the span of millions of years, Slate is one of the oldest roofing materials in the history of modern construction. Known widely for its durability and reliability as a weatherproof roofing material, slate was originally the roofing material of choice for royalty and nobility alike. As the centuries progressed, as well as the technology and technique involved in both slate extraction and modern construction, slate quickly earned its reputation as the most effective shingle available. Given that it is extracted from the ground without any chemical intervention, as well as its century-long service life, slate is among the most environmentally friendly roofing materials available.

Some of the most exciting buildings we have contributed to the restoration of include:

  • Ford’s Theatre (Unfading Black Slate Roof Tiles)
  • The US Chamber of Commerce (Unfading Black Slate Roof Tiles)
