Vermont Semi-Weathering Gray/Green

Semi-Weathering Gray/Green, also known as Sea Green – a historically popular and high-volume product. A green or gray/green color when first quarried; after application to the roof and exposure to the elements, a percentage of these slates weather to shades of buff and brown. The degree of weathering will vary from quarry to quarry and can range from less than 10% to more than 90%. As about a dozen quarries currently produce Semi-Weathering Gray/Green roofing slate, a subtle range of color, texture and weathering characteristics can be expected.
