Canadian Unfading Black roof slates (North Country Unfading Black)

Posted By On 23 Apr 2018

Our Canadian Unfading Black roof slates are produced from a single source in St Marc Du Lac Long, Quebec, Canada near the Maine/New Brunswick border. This blue-black slate supplied 80 percent of the Canadian market during the 1880’s and the 1890s.

Our history with the Glendyne quarry dates back to 1995 when we were awarded the North American distribution rights to their blue/black slate.  To many it’s known as North Country Unfading Black and to those in the slate valley it’s called Canadian Black.

Our Canadian Slate quarry prides itself on preserving the environment.  In 2003, a tree planting program was implemented to not only improve the landscaping but to control soil erosion.  The quarry also has three sedimentation ponds and the water is constantly tested.  Staff’s health is also very important and the plant invested in a powerful dust controller.

Canadian slate is durable in extreme weather conditions, it’s unfading, high quality guaranteed to last 75 years! Conforms to International Standards (North America C406-00, United Kingdom ES 12326-2, Belgium STS 43.03.6 and France NF228).

Our North Country Unfading Black/Canadian slate is a premium-quality roofing slate offering an elegant and lasting roof for both new construction and restoration projects.  This Canadian slate is smooth, rich black slate with a slight luster and has been often compared to the famous slate of the Monson region of Maine.

Medium Texture 

The Glendyne quarry prides themselves on providing a quality product.  Part of their quality control comes down to the attention to detail and sorting the pallets by the various thicknesses.  When you order a ¼” slate, each piece is examined to ensure it’s an even thickness around each piece.  Pieces that might be ¼” on one end and 3/8” on the other end, are put into a Medium Texture pallet.  The quality is still ASTM S1, but will require a little more attention by the roofing contractor when installing to ensure the various thicknesses are sorted.  If you prefer a more textured roof, the medium texture unfading black roof slates are the way to go!
