The Hidden Dangers of Improper Roof Shingle Disposal (And How to Avoid Them!)

Replacing old and worn roof shingles is a common home improvement project. But what many homeowners don't realize is that how they dispose of their old shingles can have major consequences for the environment and their own health and finances.

Improperly discarding old asphalt shingles contributes tons of waste to landfills each year. It also poses risks of toxic materials leaching into soil and waterways. There are safer, more sustainable ways to dispose of roofing shingles without incurring fines or lawsuits over health and environmental damage.

The Environmental Impact of Shingle Waste

It's estimated that over 11 million tons of asphalt roofing shingle waste is generated in the United States each year from reroofing projects alone. That's enough to cover over 4,000 football fields! Obviously, tossing all of those used shingles into local landfills takes up a massive amount of space.

In addition to taking up landfill volume, improperly disposed asphalt shingles can leach toxic substances like lead, PAHs (polycyclic aromatic hydrocarbons), copper, zinc and chromium into surrounding soil, groundwater and waterways. This poses risks to local ecosystems and communities.

Recycling and Reuse Opportunities

Many of the potential dangers from shingle waste can be avoided by recycling old roofing materials instead of sending them to landfills. Recycled asphalt shingles can be processed into hot mix asphalt, road surfaces, or even used as an additive for making new shingles.

Some shingles can also be reused for projects like gardening paths or shed roofs if they are still in good condition. Donating to local charities and community organizations is another great reuse option.

Health Risks of Improper Asphalt Shingle Disposal

In addition to environmental hazards, improper shingle removal and disposal can also pose health risks - especially from asbestos exposure. Asbestos was commonly used in roofing shingles until the 1980s, so homes built before this period often contain asbestos shingles.

When old asbestos shingles are broken up during removal, it can release dangerous fibers into the air. Exposure to asbestos increases risks of lung diseases like mesothelioma and asbestosis. Proper respirators and containment procedures are crucial when removing potential asbestos shingles.

The Importance of Asbestos Testing

Because the health risks are so severe, it's critical that all old shingles be tested for asbestos content before tear-off and disposal. A licensed asbestos inspection will identify if there are asbestos containing materials (ACMs) present so that proper precautions can be taken.

If testing confirms asbestos, ACMs must be removed by a licensed abatement contractor and disposed of at a regulated landfill. The costs and liability associated with improper asbestos shingle disposal make testing an essential first step.

Legal and Financial Risks

Along with environmental and health risks, improper shingle disposal can lead to legal problems and costs. Depositing waste in unauthorized areas or sending asbestos to regular landfills breaks laws regulating waste management and pollution.

Homeowners may face fines of $25,000 per day or more for violations. The EPA and state regulators can also hold violators financially liable for environmental cleanups and restoration costs. Lawsuits related to health issues from asbestos or environmental damage can also result in massive liabilities.

Working With Local Waste Management

To avoid legal issues and fines, homeowners should coordinate with their local waste management department before shingle tear-off. This ensures you follow all protocols for containment, asbestos testing, and disposal.

Waste management officials can advise on recycling options in your area and if special pickups are required. Keep documentation of your shingle disposal to verify proper protocols were followed.

Now that you know the many hazards of DIY shingle disposal, here are some tips for safe and sustainable tear-off:

While being mindful of potential risks, re-roofing doesn't have to generate tons of dangerous waste. Follow safe handling procedures and take advantage of recycling programs in your area. We all have a role to play in reducing environmental impact and keeping communities healthy - starting with the roofs over our heads.
