IKO Crowne SlateTM Designer Laminated Shingles. Slated for Greatness in Look, Performance and Speed of Installation.

When a prospect wants the look of a natural slate roof, you can’t do much better than to recommend IKO Crowne Slate designer laminate shingles. Real stone could mean having to reinforce the roof deck to support the added weight and finding a contractor with the necessary expertise to install slate could be time-consuming as well as expensive.

High-definition color choices

Thanks to IKO’s exclusive, advanced color blending technology, you can offer two high-definition color choices that mimic the character and charm of natural stone so well, only you and the homeowner will know that these are asphalt roofing shingles. Plus this process virtually eliminates the headache of mismatched color lots.

Algae Resistant Granules

We crush and color our own granules and also embed special ones that help inhibit the growth of blue-green algae that can cause unsightly black streaks and discoloration.

10" exposure

IKO Crowne Slate shingles are designed with square cuts to resemble actual slate tiles and feature the colors of natural stone. The difference is that the individual tiles of Regal Stone are of uniform but contrasting color, creating an overall randomized or patchwork effect often associated with genuine slate. Each tile of the Royal Granite blend has gradations of more subtle colors within the range of real slate for a more muted, yet still completely natural-looking appearance.

These large square cuts are shown off to best advantage because of the incredibly generous 10″ exposure of IKO Crowne Slate roofing shingles. They’re the largest we make in their class.


You’ll get 40 shingles to a square. Compare that to some other brands of similar product that can package 50 shingles or more to a square and you’ll see how you can get a minimum of 10% more coverage for potentially less labor, less waste and faster installation with IKO Crowne Slate. The sooner your crews can complete a project, the sooner they can take on the next and the better for your bottom line.

Why You Can Recommend IKO Crowne Slate Shingles with Pride and Confidence

IKO Crowne Slate designer shingles are solidly constructed of two fiberglass mats laminated together. The lower “shim” is coated with asphalt we oxidize ourselves. The upper “lid” or “cap” is saturated with our special modified asphalt for superior weather-resistance and a Class A Fire Resistance rating.

This double construction imparts a dimensional thickness that further enhances the appearance of natural slate tiles and gives the shingles extra weight, to lie flat and stay flat, helping to minimize the risk of blow-offs.
