A more sustainable shingle using recycled shingle content1

Learn about asphalt shingle recycling and the RoofCycle™ Process

The GAF RoofCycle™ Process is a breakthrough, patented recycling process that diverts shingle waste from landfills and reuses it in the manufacture of new GAF shingles. Timberline HDZ® RoofCycle™ Series Shingles1 contain approximately 7% recycled content without sacrificing any of the quality you demand from a GAF shingle.

Receive Updates
¹ Timberline HDZ® RoofCycle™ Series shingles identify the percentage of recycled shingle content in the product near the color and barcode on the wrapper and are only available in limited quantities/areas at this time. Products without this information do not contain recycled shingle content.

Will help divert shingle waste away from landfills
 More than 13 million tons of shingle waste is generated each year and much of it ends up in landfills. The RoofCycle™ Process will help divert some of that waste for use in shingle manufacturing.

Shingles containing recycled material
 GAF plans to use about 90% of the shingle waste that it collects to manufacture new shingles.

Same great Timberline® quality you expect
Timberline HDZ® RoofCycle™ Series Shingles1 contain about 7% recycled content and will provide the same quality and performance you expect from a GAF roof.

Each year in the U.S., roughly 13 million tons of asphalt material gets torn off of old roofs to make way for new asphalt shingles. Currently, only about 10% of that tear-off gets recycled for use in paving and other roadway projects. That leaves about 12 million tons of waste to get shipped to landfills each year.
