Trace minerals give Vermont Roofing Slates their many colors. The "Weathering" and "Semi-Weathering" slates contain some layers with trace amounts of iron. After a few months of exposure to light and moisture, slates with an iron-bearing surface layer, will oxidize to some shade of brown. Slates which change color may be designated "Weathering" or "Semi-weathering" depending on the extent of the color-shift. Slates weather differently from quarry to quarry and even within quarries, so a thorough "stirring" before installation is recommended.

Sea Green - Weathering

Our Sea Green is green or grey/green when first quarried. After application to the roof and exposure to the elements, the majority of these slates weather to shades of buff and brown. The predictability of this color change is particularly advantageous when replacing or repairing brown slate or when trying to achieve a brown roof. Produced in Vermont.

Semi-Weathering Grey/Green

One of the most durable and plentiful of the Vermont slates. A pleasurable material to work for the slate craftsman - cuttable and consistent. This stone is grey/green when freshly quarried and a naturally harmonious blend of greens, greys and buff after weathering. Produced in Vermont.
