Washington, DC Slate Shingles

Washington, D.C. the capital of the United States, is home to the White House, countless historic buildings and foreign embassies that makeup the city’s various architectural styles. North Country Slate has been supplying North American produced natural roofing slate in Washington, DC for over 20 years. Our experience encompasses institutional, military, commercial and residential projects in both the new construction and restoration sector. We work closely with architects, roofing contractors and owners of government, religious and institutional buildings to assist them in the preservation of historic structures. We also offer similar support to decision makers on new commercial and custom home projects.

A slate roof will be one of your homes biggest investments, and one of the longest lasting products you will find. It’s important to do your research to make sure you are getting a quality product which passes the requirements of an ASTM S-1 rated roofing slate. North American quarries have a proven track record when it comes to offering a premium slate at the highest standard.

Our North Country Unfading Black slate is available in both smooth texture and medium texture and is quarried in Canada. This slate deposit was discovered in the early 1900’s when the transcontinental railway was built. The quarry stopped production during World War 1 and resumed operations in 1995. North Country Slate has been the exclusive North American distributor since 1997. North Country Unfading Black (“Canadian Black” or “Blue/Black”) has been a historic match for the slates of Monson, ME, and Peach Bottom, PA.

Our colored slates come from select quarries along the Vermont/New York state border. These colors include; Semi-Weathering Black, Semi-Weathering Gray/Black (Strata Gray), Semi-Weathering Clear Gray, Unfading Gray, Unfading Purple, Semi-Weathering Purple, Unfading Mottled Purple and Green, Unfading Green and Semi-Weathering (Sea) Green. Roofing slate has been quarried in this area since the 1840’s. We pride ourselves on our quality of slate, delivery and significant inventory, to serve our customers better.
