Asphalt Shingle Recycling *Source: National Asphalt Paving Association Asphalt is Americas most recycled material 92% of Americas roads are asphalt* More and more roofs are recycled into roads every day Slide 5
Shingles can improve pavement properties… Four Times the Asphalt Content High grade aggregate Fibers Limestone Slide 6 Source: Construction Materials Recycling Association
Shingle Recycling Locations - Nationwide 7 VISIT TO FIND RECYCLERS
Tear-Off For Recycling Tear off the roof normally Keep shingles separate from wood, metal, jobsite scrap Nails and felt are OK Separate out large quantities of caulk and mastic (more likely to contain asbestos) The goal is to get the shingles, felt and nails into a separate pile or container, with a minimum of extra effort Wood is the worst contaminant –Hard to separate, and bad for pavement 8
Nails Removed by Powerful Magnets! 9 SHINGLE GRINDER
Dos and Donts 10 Do:Dont: Shingles, Felt and Nails only – Dont Mix in Other Materials
At the Collection Yard Flashings are also recycled Feeding the Grinder 11
Ask for Documentation 12
MAKING A DIFFERENCE BY RECYCLING 13 Average Roof of squares 3.5 tons or 7000 lbs of roofing 5 cubic yards of landfill space The equivalent of more than one year of a typical familys trash Instead, used at 5%, this could help pave over 50 feet of typical road! Source of trash data: DOE Source of Road Data: NAPA 13
Challenges in Shingle Recycling At one time, some roofing and caulk contained asbestos This is much more likely on the older or multi- layer tear-offs You may need to sign a delivery certification form Testing is available for large jobs – approx cost = $25 Slide 14

Economies of Scale Full Trucks=Better Pricing –3Insulation: 140sq/truck –Membrane: 400sq/truck Combining materials on a load is possible –But may affect pricing 22 *these numbers are approximate and will vary by job
Making a difference by recycling By Recycling an Average Roof of 240 Squares, you can divert: –Approx cubic feet of insulation –Approx pounds of membrane This amount of material would fill three average swimming pools 23 Source: Nationwide Foam
