When it is time to replace a roof, homeowners and contractors are often left with thousands of pounds of waste. Shingle recycling offers a sustainable solution that keeps roofing debris out of landfills and repurposes it for infrastructure projects. By understanding how to properly dispose of old shingles, you can save money on disposal fees and contribute to a more circular economy.
The Importance of Shingle Recycling
Asphalt shingles are the most common roofing material in North America. Because they are made of petroleum-based products, mineral granules, and fiberglass or organic felt, they take centuries to decompose in a landfill.
Recycling these materials is a practical way to reduce environmental impact. Every year, millions of tons of roofing waste are generated, and recycling helps recover valuable resources that would otherwise be lost.
Beyond the environmental benefits, shingle recycling is often more affordable than traditional landfill dumping. Many recycling centers charge lower “tipping fees” for clean asphalt shingles compared to mixed construction debris.
Benefits of Recycling Your Roof
Choosing to recycle your shingles provides several key advantages for both the homeowner and the community. Understanding these benefits can help you make an informed decision during your next home improvement project.
- Resource Conservation: Shingles contain asphalt, which is a valuable byproduct of oil refining. Recycling them reduces the need for new oil.
- Road Construction: Recycled shingles are most commonly used to create Hot Mix Asphalt (HMA) for paving roads, driveways, and parking lots.
- Energy Savings: Processing recycled asphalt requires less energy than extracting and refining new raw materials.
- Landfill Space: Roofing materials account for a significant percentage of construction and demolition waste. Recycling keeps this bulky material out of local dump sites.
What Types of Shingles Can Be Recycled?
While most modern recycling facilities focus on asphalt shingles, it is important to know which materials are accepted. Most facilities distinguish between “clean” loads and “mixed” loads.
Asphalt Shingles
Composition shingles, also known as asphalt shingles, are the primary target for recycling. These include both organic and fiberglass-based shingles used on residential homes.
Wood and Slate Shingles
Wood shakes and slate tiles are also recyclable, but they usually go to different types of facilities. Wood can be turned into mulch or biomass fuel, while slate can be crushed for gravel or landscaping stone.
Metal Roofing
Metal roofing is highly sought after by scrap metal recyclers. If you are removing a metal roof, you can often sell the material to a local scrap yard for a profit.
Step-by-Step Guide to Shingle Recycling
If you are planning a roof replacement, follow these steps to ensure your shingles are recycled correctly. Preparation is the most important part of the process.
1. Find a Local Recycling Center
Before the project begins, locate a facility that accepts asphalt shingles. You can search online for “construction and demolition recycling” or use databases like Earth911 to find locations near you.
2. Confirm Acceptance Criteria
Call the facility to ask about their specific requirements. Some centers only accept shingles from residential projects, while others may require testing for asbestos if the shingles are very old.
3. Separate the Waste
To qualify for the lowest recycling rates, you must keep the shingles separate from other debris. Do not mix shingles with wood, plastic packaging, or household trash. Most facilities allow roofing nails to remain in the shingles because they use large magnets to remove them later.
4. Arrange for Transportation
Decide if you will haul the shingles yourself or hire a roofing contractor who offers recycling services. If using a dumpster rental company, specify that you want a “shingle-only” dumpster for recycling purposes.
How Shingles Are Processed
Once the shingles arrive at a recycling facility, they undergo a specific mechanical process to become reusable material. This transformation is what makes the material valuable for road crews.
First, the shingles are inspected for contaminants like wood or large pieces of metal. Then, they are fed into a powerful grinding machine that shreds them into small pieces, usually less than half an inch in size.
During the grinding process, powerful magnets extract the roofing nails. The final product is a consistent, dark granulated material that can be mixed with crushed stone and new asphalt to create high-quality pavement.
Common Challenges and Solutions
While shingle recycling is becoming more common, there are still a few hurdles you might encounter. Being prepared for these issues will make the process smoother.
Availability: Not every city has a dedicated shingle recycling plant. If a facility isn’t nearby, the cost of hauling the material long distances might outweigh the savings. In this case, look for general construction waste recyclers who sort materials off-site.
Asbestos Concerns: Shingles manufactured before the mid-1980s may contain asbestos. If your roof is very old, a recycling center may require a lab test to prove the material is safe before they will accept it.
Contamination: If your load of shingles contains too much trash, the facility may reject it or charge you the higher landfill rate. Ensure your roofing crew understands that only shingles and nails should go into the recycling container.
Cost Comparison: Recycling vs. Landfill
In most regions, recycling shingles is a cost-effective choice. Landfills typically charge by the ton, and because shingles are very heavy, these costs add up quickly.
Recycling centers often offer a discounted rate because they can sell the processed shingles to paving companies. By choosing a recycler, a contractor or homeowner can often save between 20% and 40% on disposal fees.
When getting quotes from roofing contractors, ask if they include recycling in their bid. Some contractors may offer a small discount if they know they will be saving money on tipping fees at the recycling center.
Tips for a Successful Recycling Project
To make the process as efficient as possible, keep these practical tips in mind during your roof tear-off. Small efforts during the cleanup phase lead to better results.
- Use a Tarp: Lay down large tarps around the perimeter of the house to catch shingles as they are removed. This makes it easier to gather them without mixing in grass or dirt.
- Communicate with Your Crew: If you are hiring professionals, make it clear from the start that you want the shingles recycled.
- Check the Weather: Wet shingles are much heavier than dry ones. If possible, keep your recycling container covered if rain is expected to avoid paying for the extra weight of the water.
- Keep it Pure: Avoid putting plastic wrap from new shingle bundles or felt paper scraps into the recycling bin unless the facility specifically allows it.
Conclusion
Shingle recycling is a simple yet effective way to handle one of the heaviest waste products in home maintenance. By diverting asphalt shingles from landfills, you are supporting the construction of better roads and conserving natural resources. Whether you are a DIY homeowner or working with a professional roofing company, taking the time to recycle is a responsible and cost-effective choice.
