About this brand
Structural slate and domestic quarry relationships
Vermont Structural Slate supplies real stone roofing for jobs where the assembly is engineered, not guessed.
S1-grade material with low absorption is the baseline when Colorado freeze-thaw cycles matter.
Hand setting, headlap, and copper or stainless fasteners are standard conversations. This is trade work.
Hail scars stone differently than it destroys laminates. The weak point is usually flashings, not the field slate.
Material
Natural metamorphic slate, quarried
Impact
Stone is dense; grading and thickness drive real-world hail behavior
Wind
Depends on hook, nail, and headlap method per project spec
Fire
Non-combustible stone
Warranty
Quarry and supplier terms vary; field performance ties to installation quality
Products and colors
CUPA 50
Spanish CUPA slate, deep gray with thin laminations and a calm face. Non-carbonated and uniform. I specify it when the client wants a refined European gray field without a lot of visual noise.
CUPA 3
Blue-black slate with a gritty face. Parallel grain lines show up in some pieces. It reads darker and more textured than CUPA 50 from the curb.
CUPA 7
Non-carbonated black slate from Spain with thin laminations and a smooth surface. Good when you want a dense black-gray roof without the chatter of a heavy texture.
Vermont Multi-Color Blend
Custom blend built from the Vermont colors you pick. This example mixes unfading green, red, and purple. Blends need clear samples so the roof does not drift from what you pictured.
Vermont Gray Black Blend
Darker cousin of Historic Vermont: semi-weathering gray, mottled gray-black, and Vermont Black. Some pieces pick up green in bright sun, then bronze and buff as they age. Strong earth-tone movement.
Charleston Blend
Mix of Vermont unfading green and Vermont gray-green. Soft contrast. Popular on coastal and stucco homes where you want green-gray without shouting.
Historic Vermont Blend
The classic domestic trio: semi-weathering gray-green, unfading green or gray-green, and purple. Texture runs smooth to medium. Semi-weathering pieces bronze over time. You see this blend on a lot of landmark roofs.
New York Red
Bright unfading red out of Washington County, New York. Hard and dense. Rare color in slate. Use it when the design calls for a true red that holds.
Vermont Mottled Purple
Purple and green marble through each piece. Some roofs read mostly purple, some mostly green. Medium texture. Weathering stays minimal. No two bundles look the same.
Vermont Unfading Green
Quiet green with small gray flecks. Softer than grassy greens. Stable color. Works as a full roof or as an accent in a blend.
Vermont Semi-Weathering Gray/Green
Starts gray-green on the wall. A solid share weathers to buff and brown on the roof. Historic domestic favorite. Good when you want a lighter roof that gains character over time.
Vermont Semi-Weathering Gray
Traditional slate gray from clear to lightly marked black. Expect bronze to buff weathering. Smooth to medium texture. Fits earth-tone palettes.
Vermont Unfading Gray
Medium texture battleship gray with black markings. Little buff weathering. Can pick up a hint of green when wet. Good when you want a controlled gray field that still has depth.
Vermont Strata Gray
Medium gray with black strata stripes. Medium to heavy texture. Buff and brown weathering adds contrast. The stripes break up the field in a big way.
Vermont Black
Medium to heavy texture. Medium-dark gray body with darker linear marks. Not a rainbow weathering slate. You might see light bronzing on the palest pieces over decades.
CUPA 14
Spanish blue-black slate from Las Fuentes. Quartz gives it a little sheen in sun. Closest living cousin to old Buckingham and Peach Bottom looks we see specified now. Heavy texture option when you want presence.
