J Bretz
• President of Excel Roofing, Inc. An Englewood,
CO based roofing Company.
At the age of 28, J Bretz founded Excel Roofing in 1993. Excel’s focus has
always been residential re-roofing. During the last 20 years, Excel Roofing
has removed hundreds of thousands of squares of old roofing material and
sent the majority of this material to landfills. When asphalt shingle recycling
was occurring in Denver, Excel quickly embraced the idea and re-trained
their crews to the requirements necessary to recycle asphalt shingles. Excel
quickly became one of the largest recyclers of asphalt shingles in the
Jerry Lambert
• Asphalt Shingle Grinding Service, LLC &
Recycling & Processing Equipment, Inc., Vice
President of Operations
Mr. Lambert currently manages 5 crews and the equipment for Asphalt
Shingle Grinding Service LLC as they travel the country processing shingles
for Asphalt Companies, Recycling Centers and Paving Contractors. Since the
late 1980’s, he has been personally involved in producing well over a million
tons of RAS, both manufacturers’ waste and post consumer or tear off
shingles. This experience has given him extensive "hands-on" knowledge of
the ins and outs of turning Asphalt Shingles into a useful product. ASGS
client list includes some of the largest asphalt companies in the US and
some of the smallest and caters to their specific needs by utilizing the right
equipment and processing methods in a cost effective way. This has led him
to believe that by getting roofing contractors and the recycler to work
together in making the processing of RAS more cost effective, the potential
for industry growth is, "Through The Roof!"
Dan Horton
• Asphalt Shingle Recycling Systems
After 23 years in the building materials business, Dan Horton left his executive
position at IKO Industries, a roofing manufacturer, to establish Asphalt Shingle
Recycling (ASR) Systems in 2009. He has patented a method of recovery of raw
material from shingles for re-use by roofing manufacturers, roofing related products,
and the paving industry. ASR Systems is currently operating in Bristol, TN.
Dan's team is proud of cleaning up approximately 30,000 tons of a competitor's
speculative storm collection of asphalt roofing shingles in Knoxville, Tennessee. The
effort preserved shingle recyclers reputation in Tennessee and further developed a
positive influence on the state's Department of Environmental Quality (DEQ).
Dan Horton believes that an extensive national asbestos study is a necessary step
towards widespread adoption of shingle recycling. Such a study will establish the
safety of recycled shingle products and increase sustainability in the roofing
industry. That is why he has spearheaded the campaign to utilize Green Squares'
software to aggregate data yielding a comprehensive view of asbestos incidence
rates. Dan is calling for all shingle recyclers and industry members to join him in the
effort by contributing statistics and considering sponsorship.
