Millennium Slate LLC Revolutionizes Roofing Slate Installation

New patent-pending roof attachment method with 10x time savings on installation.

Hook and Loop Adhered Roof

​At the International Roofing Expo, Dallas, Texas, Millennium Slate LLC has today announced a revolutionary method of installing slate roofs, trademarked The Centennial System™.

The system involves factory-applied hook and loop strips on the front and rear of individual slate tiles. Millennium is launching this product with market-leading hook and loop fasteners from Velcro. The individual slate tiles are applied to a roofing substrate covered with hook fasteners. This launch underlayment is InsulBase RL™ by Carlisle Construction Materials. Millennium has domestic and international patents pending.

Millennium has wind-tunnel tested this system at 160mph with no damage. Environmental testing down to -40F and up to 250F means this system will be appropriate in all climates. Since no nails are used, hundreds or roof penetrations per square of roofing are avoided. Millennium’s system weighs about 4.5 pounds per square foot vs. 9 pounds for traditional slate. Installation speeds of 5x to 10x or more vs. traditional slate have been demonstrated. While Millennium is very pleased with environmental and wind testing, offerings from other hook and loop manufacturers are being evaluated which could result in increased performance and lower costs.

Chad Buhrman, Insulation Product Manager, Carlisle Construction Materials said, “Millennium has selected our field-tested and commercially available InsulBase RL ™ Polyiso for their underlayment. The RapidLock product line has become extremely popular with our installers.  We have sold millions of square feet of RapidLock into the low-slope roofing market, and we are excited to help facilitate Millennium’s move into the steep-slope market.

Millennium has appointed Phil Prehoda President. Prehoda will retain his title of Vice President of Sales at Evergreen Slate Co Inc. Evergreen is Millennium’s majority shareholder. Prehoda said, “Over the years we’ve looked at all the hook, clip and rail systems that have tried to replace traditional slate application methods. This highly automated system of applying the hook and loop tapes in our factory will be a tremendous speed up and simplification of the slate application systems that have been used for centuries. We are presently evaluating other roof types for this system and will be looking at other parts of the building needs such as ceiling and floor tiles, siding, fascia and wall cladding. Evergreen will continue to pursue traditional slate application and Millennium will open the market for slate in lighter weight and quicker application scenarios.”

Millennium is showing the system to selected roofers who will be granted protected territories.  Millennium has spent the necessary capital to patent the system, equip the factory for automated production, do environmental testing, and get into low volume production.  Millennium is seeking equity investment from accredited investors that will allow the purchase of inventory, significant expansion of the automated manufacturing system, prototyping and testing of the system with other building materials, and development of marketing and training materials.
