  • Water Resistance
    Extremely dense, the unique composition of slate roofing tiles make them waterproof.
  • Fire Resistance
    Slate is among the most fire-resistant roofing options available. The naturally fireproof composition of slate tiles can prevent airborne sparks from neighboring buildings and wildfires from igniting.
  • Ease of Maintenance
    Extremely resistant to mold and mildew growth, Vermont slate tiles rarely require cleaning. In the rare event of tile damage, repair is minimal, with only individual damaged tiles requiring replacement. Unlike composite shingle roofing, which must be replaced every 20-30-years or more depending on weather, slate roofing can last 75+ years, reducing the need for cumbersome re-roofing.
  • Environmentally Friendly
    One-hundred-percent natural and long-lasting, slate tiles do not contain any toxic chemicals, adhesives, or sealants. The low environmental impact of natural slate roofing makes it a top-choice for sustainable building design. Sourced locally from Vermont, it is incredibly long lasting with a low carbon footprint. It won’t fill up space in landfills or pollute the environment, and can even be recycled at the end of its lifespan.
