Old roofing materials should not be placed in a household recycling bin. In Ithaca, NY, the correct handling method depends on the material, its condition, whether it is contaminated, and whether it may contain asbestos.
Asphalt shingles are often eligible for construction-and-demolition recycling, while metal, wood, slate, and reusable roofing components may have separate reuse or recycling options. Roofing waste should be kept dry, sorted, and free of household garbage whenever possible.
What roofing materials can be recycled?
The most commonly recyclable roofing material is clean asphalt shingle waste. Many construction-and-demolition processing facilities can accept uncontaminated asphalt shingles and roofing felt that do not contain friable asbestos. Recovered shingles may be processed into material used in paving and other construction applications.
Other roofing materials may also have value:
- Metal flashing, gutters, valleys, and vents: These are generally handled as scrap metal if they are free of excessive sealant, insulation, or other attached debris.
- Wood sheathing and roof framing: Clean, untreated wood may be reusable or recyclable through a construction-materials facility.
- Slate and clay roofing: Intact pieces may be reused for repairs or architectural projects. Broken pieces may sometimes be accepted with masonry or construction debris.
- Synthetic roofing membranes: These are more difficult to recycle because acceptance depends on the exact material and the receiving facility.
- Roofing insulation: Some rigid insulation products may be reusable or recyclable, but they are usually not accepted with asphalt shingles.
- Roofing paper and underlayment: These may be accepted with asphalt shingles at some facilities, but not all. Materials should be separated and confirmed before delivery.
A mixed roofing load can be rejected even when one portion of it is recyclable. Sorting at the job site usually provides more disposal options.
Can old asphalt shingles go in curbside recycling?
No. Asphalt shingles do not belong in a curbside recycling cart or household recycling bin. They are bulky construction-and-demolition debris, not packaging or ordinary household recyclables.
They should also not be placed in regular household trash unless the local waste program specifically allows that type and quantity of material. Roofing tear-offs can be heavy, sharp, and difficult for collection workers to handle. Loose shingles may also damage collection equipment or create roadside debris.
For residents using the Tompkins County waste system, roofing materials generally require separate arrangements through the county’s recycling and solid-waste resources or an appropriately authorized construction-and-demolition facility. Acceptance rules, loads, fees, permits, and vehicle requirements can change, so those details should be checked before transporting the material.
How should roofing waste be prepared?
Good preparation reduces contamination and makes it easier to determine whether the material can be recycled.
Before loading the material:
1. Remove household garbage, food waste, plastic packaging, and loose insulation.
2. Separate metal, wood, shingles, slate, and other roofing products.
3. Pull out large pieces of flashing, pipe, wiring, and other non-roofing debris.
4. Keep recyclable materials as clean and dry as practical.
5. Use a covered truck, trailer, or secured container so pieces cannot blow onto roads.
6. Avoid overfilling containers because shingles and metal can fall during transport.
7. Keep suspect asbestos-containing materials isolated from ordinary roofing waste.
Small amounts of attached nails are commonly associated with asphalt shingles, but excessive nails, screws, brackets, and other metal may cause a load to be classified differently. A facility may also require shingles to be loose rather than bagged, or may prohibit certain bags or containers.
What if the roof is old or may contain asbestos?
Do not assume that every old roof contains asbestos, but do not assume that every old roof is asbestos-free either. Asbestos was used in some roofing shingles, roofing felts, built-up roofing, cement products, coatings, and mastics.
The greatest concern is material that has become friable, meaning it can crumble, pulverize, or release fibers through ordinary handling. Cutting, grinding, breaking, sanding, or using power equipment can increase the hazard.
If asbestos is suspected:
- Do not sweep, grind, pressure-wash, or dry-cut the material.
- Do not mix it with ordinary asphalt shingles.
- Do not place it in curbside recycling or household trash.
- Keep people away from loose dust and damaged material.
- Confirm the required handling and disposal method before moving it.
New York requirements distinguish between different asbestos conditions and removal activities. Special rules may apply even when roofing appears intact. If the material is damaged, dusty, layered with unknown underlayment, or likely to become crumbled during removal, a qualified asbestos specialist may be necessary for safe assessment and handling.
A recycling facility that accepts asphalt shingles generally requires the material to be free of friable asbestos. That requirement is not the same as a guarantee that every roofing product is safe to disturb.
Can roofing materials be reused instead of recycled?
Yes, reuse is often preferable when materials can be removed without damage. Sound slate, clay tiles, copper components, decorative ridge caps, historic trim, and undamaged metal roofing may be useful for repairs or small projects.
Reuse is most practical when the material is:
- Clean and dry
- Free of lead-based coatings, heavy tar, or unknown contamination
- Not cracked, badly rusted, or structurally weakened
- Removed without excessive breakage
- Stored off the ground and protected from weather
Reusable roofing materials should not be passed along if their age, condition, or coating creates a health or structural concern. A piece that looks usable may still have hidden corrosion, brittle fasteners, or asbestos-containing components.
How does Ithaca’s climate affect roofing disposal?
Seasonal weather can complicate both removal and storage. Snow, freeze-thaw cycles, spring rain, and summer humidity can make old roofing slippery, heavy, or difficult to keep clean.
Wet shingles are heavier and may stick together. Water can also wash roofing grit, tar, or loose debris into soil and storm drains. During a tear-off, tarps and covered containers help prevent runoff and windblown waste.
Roof work should be planned around stable weather, especially on steep or multi-story roofs. Ice, wet decking, and sudden temperature changes increase fall and handling risks. Roofing waste should not be left in a yard where children, pets, pedestrians, or snow-removal equipment could encounter exposed nails.
What is the simplest disposal decision?
Use this basic sequence:
- Clean asphalt shingles: Ask an authorized construction-and-demolition facility whether they accept them for recycling.
- Metal roofing and flashing: Separate it and ask about scrap-metal acceptance.
- Reusable slate, tile, or specialty components: Keep intact and assess for reuse.
- Mixed or contaminated debris: Ask the receiving facility how it must be classified.
- Suspected asbestos material: Stop normal handling and obtain instructions for compliant management.
- Small quantities from a repair: Confirm whether the local solid-waste system accepts them and whether special fees or preparation rules apply.
The key distinction is between ordinary household recycling and construction-material recovery. Roofing waste belongs in the second category, and the safest route is to identify the material first, separate it at the source, and verify acceptance before making a trip.
