Asphalt Shingle Recycling
*Source: National Asphalt Paving Association
• Asphalt is America’s most recycled material
• 92% of America’s 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

VISIT WWW.SHINGLERECYCLING.ORG 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
pavement8

Do: Don’t:
Shingles, Felt and Nails only – Don’t Mix in Other Materials

MAKING A DIFFERENCE BY RECYCLING
13
Landfill
Average Roof of 30-35 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 family’s trash
Instead, used at 5%, this could help pave over 50 feet of typical road!

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

Ground TPO, EPDM
Rigid Foam Insulation Boards
• Expanded Polystyrene - Beadboard Insulation
• Extruded Polystyrene Insulation
• Polyisocyanurate Foam Insulation
• Composite Foam Insulationwith adhered concrete or fiberboard
18
Ballast is easily recycled
• River Rock• Slate• Concrete Pavers• Rubber Pavers
19
Cover boards• Gypsum board cut-
offs • Complete boards or
broken parts • Gypsum ceilings,
floors, walls etc. • Nails and screws are
allowed • Wallpaper, glass tissue
and other wall coverings on the boards are allowed
20
Information Needed by the Recycler
21
• Timing• # Squares• Membrane Type• Membrane Thickness• Method of Attachment• Insulation Type• Insulation Thickness• Ballast, if any• Other details
Economies of Scale
• Full Trucks=Better Pricing– 3”Insulation: 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. 4000 cubic feet of
insulation– Approx. 6000 pounds of
membrane
• This amount of material would fill three average swimming pools
