G.E.M. Inc. manufactures Euroshield®, environmentally friendly recycled rubber roofing products from a facility located in Calgary, Alberta. Founded in 1999 by Mr. Henry Kamphuis in response to the overwhelming problem of what to do with the deluge of old tires clogging up landfills and dumpsites, it employs in excess of 40 people producing Rundle Slate, Vermont Slate, Ranchlands Shake, Beaumont Shake and Vermont Slate Panel Loc. All Euroshield® products are specifically designed to overcome extreme weather, impact and temperature variances that cause splitting, peeling, cracking and rotting, undesirable characteristics associated with aging of other roofing systems. All products contain approximately 95% recycled content, the bulk of which is recycled tire rubber, and are covered by a limited transferable lifetime warranty.

Our most recent product launch was Vermont Slate SC on July 1st, 2018. Vermont Slate SC (solid core) is the world’s first Hail Proof Roof product to be warranted against impact damage from hail of any size for the first 20 years on the roof. The Beaumont Shake came along in 2016. These are thinner and lighter versions of Rundle Slate and Ranchlands Shake, designed to bridge the price gap between asphalt shingles and other pricier premium roofing materials like cedar, slate, metal and other synthetics. The panels handle and install much like asphalt and easy.

The reverse side of each Rundle Slate and Ranchlands Shake panel features small cubical chambers designed to create depth and to ensure structural integrity. In turn the cubicles trap air, creating an effective insulation barrier, which can contribute to reducing energy use in warmer climates. An added benefit to the design is additional sound-deadening qualities. The interlocking tongue and groove design of the panels provides tremendous resistance to wind uplift, adds to the structural integrity and ties the whole roof system together, producing a tight water-resistant seal for maximum performance. All Euroshield® products are warranted against hail damage caused by hail 2” in diameter or less for 50 years.
