An Expression of Your Style

What is slate roofing and why should I choose it? Slate is a fine-grained natural sedimentary rock that has been quarried and hand split into roofing tiles for centuries.

Quality slate roofs are a symbol of distinction and are prized for many benefits, including:

  • Natural, artisanal beauty
  • Performance
  • Longevity
  • Environmentally friendly
SlateTec provides natural, artisanal elegance and performance

Do traditional slate roofs weigh and cost more? Yes, a traditional slate roof adds a great deal of weight and expense to an installation, so it has not always been the ideal choice for some home or business owners.

However, the patented Genuine Roof Systems interlayment technology eliminates the overlapping materials commonly hidden in standard slate installations, reducing the weight by up to 40%. Our innovative system also eliminates the need for added hooks, battens, or rails that other lightweight systems employ. As an added benefit, the reduction of roof weight also lowers structural costs, contributing further to the system’s high value. You can now achieve the same sophisticated look showcased on palatial estates on any home due to our lightened system.

 

What does slate roofing look like? Constructed from genuine natural stone, SlateTec by Genuine Roof Systems achieves identical aesthetics as traditionally installed slate roof tiles, but without the additional weight. Don’t settle for the faux plastic slate used by other companies. The SlateTec system features the highest possible quality S-1 rated Greenstone Slate® in all of the Vermont slate colors. Our team will work with you to choose from the many slate colors and textures to create the ideal design for your specific project.

The Pinnacle of Genuine Slate. Light Weight and Guaranteed to Last.

How long do slate roofs last? A properly installed slate roof can last for a century or longer, which is a vast improvement over many other roofing systems that only last 15-20 years. Our proprietary interlayment is designed to protect against weather and UV deterioration for 100 years when combined with our slate. This major improvement to your prized investment is simply the best way to increase the value of your real estate.

IMPORTANT INFORMATION ABOUT SLATE COLORS, WEATHERING, AND FADING
Thousands of slate roofs that were installed in the 1800s are still in service today. But with such an impressive and long history, many terms describing the material have been coined and, over the years, some have been misinterpreted. For example, a common misconception associated with slate nomenclature occurs when the terms weathering and fading are erroneously interchanged. Below is a clarification of slate terms:

NOMENCLATURE OF SLATE

  • Fading: The term fading refers to certain slates that, after prolonged exposure to the elements, exhibit a chalk-ashen residue on the exposed surface of the slate. The chalk-ashen residue is the result of a chemical reaction and the associated release of calcium from the body of the slate. This release weakens the structural integrity of slate and is detrimental to the slate’s life expectancy. The term is most often used in conjunction with the Blue Black or Black slates of Pennsylvania and Virginia.
  • Non-fading or Unfading: These terms refer to certain slates that, after a prolonged exposure to the elements, do not produce the chalk-ashen residue. Non-fading or unfading slates usually have greatly-extended life expectancies over those slates prone to calcium release.
  • Classification of Colored Slate: Colored slate does not fade, but it will experience varying degrees of color change. This weathering of slate is due to the oxidation over time of minerals embedded in the slate. Depending on mineral content, the weathering process slowly changes the slate color. The color change is often a movement toward buff, brown, gray, or tan. This surface oxidation is not detrimental to the slate’s structural integrity and does not shorten the life of a roof. Colored slates are classified in three types, based upon the degree of color change over time:
    • Weathering: The term weathering refers to slates that will exhibit the largest number of individual pieces that will transform from the original color to an earth tone. All colors are “semi-weathering” unless otherwise specified.
    • Non-Weathering: The term non-weathering refers to slates that exhibit the least amount of color change.
    • Semi-Weathering: The term semi-weathering refers to roofing slates that have varying mineral content. Some of these slates will undergo a color change, while others remain their original shade. The percentage of semi-weathering slates that will experience color change is variable depending upon the location in the quarry from which the slate was extracted.

SLATE COLOR DESCRIPTIONS

Semi-Weathering Vermont Black:

The SlateTec Vermont Black is a premium quality slate roof tile with shades of gray and black. It is one of the most common slate colors and is used extensively on residential, commercial, and institutional buildings where a traditional slate roof appearance is desired. Although it is generally considered a uniform gray-black roof in appearance, approximately 4-6% of these slates will exhibit slight signs of weathering after 12-18 months of exposure. The Vermont Black slate is drawn from the Briar Hill quarries.

Vermont Black

Non-Weathering Spanish Black:

Imported from Spain, this non-fading and non-weathering elegant deep black slate is a fine quality slate with an exceptionally smooth texture. It is available as a 1/4″ smooth texture and is of the highest grade. It looks great used by itself or within a slate color blend. Spanish Black is a color not found in Vermont, but exhibits the same characteristics and has the same warranty as Greenstone Vermont slate.

Semi-Weathering Vermont Green:

Over time, this slate yields a variety of rich earth tones. When extracted from the quarry, it is monochromatic. Approximately 10-25% of the slate will gradually change to soft tones of buffs and tans after exposure to the weather. Semi-weathering Vermont Green slate gives a rustic, textured appearance to a roof and is used extensively on commercial, residential, and institutional buildings.

Non-Weathering Vermont Green:

This Vermont slate is green with shades varying slightly to light gray, and can also exhibit clouds or spots of darker gray markings. It is one of the most popular roofing slates. Non-weathering Gray Green slate can be used alone or as one of the blended colors on multi-colored roofs.

Semi-Weathering Vermont Gray:

This semi-weathering slate is an excellent hard-vein slate in shades of light to medium gray. When weathered, 10-20% of slate will exhibit buff shades.

Non-Weathering Vermont Gray:

This non-weathering Vermont slate has a soft and continuous gray hue. Sometimes described as “the battleship color,” Vermont Wells Gray exhibits soft light grays accented with an occasional splash of black. Some pieces may exhibit small markings of green. It’s a favorite of architects and owners for custom homes where they are blended with other slates to create multi-colored roofs.
