Roofs are meant to withstand the elements, from Florida’s scorching sun to torrential rain and high winds. That durability sometimes comes at an environmental cost. Many residential roofs use shingles, which could be made from toxic materials. They may also have a large carbon footprint or create pollution during installation or removal.
If you’re striving to be a more eco-conscious homeowner, we have good news. There are more environmentally friendly roofing options. And even better, they often boast a long lifespan, plus energy-efficiency benefits for your home!
Read on to learn more.
Are shingles toxic to the environment?
There are many types of shingles, all with different environmental effects. Overall, roofing materials with more chemical treatments (e.g. flame retardant) and those derived from petroleum have the greatest impact.
Asphalt Shingles
These are the most common type of roofing shingles. As the name suggests, they’re made from asphalt, fiberglass, and mineral granules. Asphalt itself is not considered toxic, but the manufacturing process may involve petroleum byproducts. Reducing your use of fossil-fuel products can lower your environmental impact.
Also, old asphalt shingles can release volatile organic compounds (VOCs) if not disposed of properly.
Wood Shingles/Shakes
Wood shingles or shakes are typically made from cedar, redwood, or other types of wood.
Because wood is highly flammable, wood shakes often include chemicals for resistance. These ingredients can potentially leach into the environment over time.
Composite Shingles
Composite shingles are made from a mixture of materials such as recycled plastics, rubber, and wood fibers. Those recycled ingredients make composite shingles more environmentally friendly than traditional asphalt shingles. However, they may still contain additives or chemicals that could be of concern, especially if you plan on collecting rainwater from your roof.
No matter which material you choose, roofing shingles can have an environmental impact.
Resource Depletion: Many roofing materials require the extraction of natural resources such as petroleum for asphalt shingles, wood for wood shingles, and metals for metal shingles. This can contribute to habitat destruction, deforestation, and other environmental concerns.
Energy Consumption: The manufacturing process for roofing shingles often involves significant energy consumption, contributing to greenhouse gas emissions and other environmental impacts.
Waste Generation: Roofing materials contribute to construction and demolition waste when old roofs are removed and replaced. Proper disposal or recycling of old roofing materials is important to minimize environmental impact.
Water Runoff: Certain roofing materials, such as asphalt shingles, can contribute to water runoff issues if not properly managed, leading to soil erosion and water pollution.
To make your home more eco-friendly, follow the three R’s: reduce, reuse, and recycle.
- Reduce your usage of roofing materials by keeping your roof in good shape so it achieves its maximum lifespan.
- Make sure your roofing contractor uses sustainable design practices, which may reduce certain materials or chemicals.
- Choose materials that are recyclable, such as standing-seam metal roofing.
- If you can’t recycle the material, be sure to dispose of your old roof properly. Ask your local roofing contractor how.

Can roofing shingles be recycled?
Yes, roofing shingles can often be recycled, depending on the material. Here’s a breakdown:
Asphalt
Asphalt shingles can be ground down into smaller pieces and incorporated into new asphalt pavement for roads, driveways, and parking lots.
Some recycling facilities also accept asphalt shingles for processing into materials used in paving and construction.
Wood
As wood is biodegradable, there are several ways to recycle wood shingles and shakes. They can be processed into wood chips or landscaping mulch. Biomass facilities can use them as part of the mixture they convert to fuel.
If you can’t recycle wood shingles. you can repurpose them. Shingles in good condition can be salvaged and reused for other construction projects or crafts.
Composite
Composite shingles made from recycled plastics, rubber, and other materials may also be recyclable, depending on the specific composition and local recycling infrastructure. These shingles can sometimes be processed alongside other plastic or rubber materials for recycling into new products.
Metal Shingles
Metal roofing materials, such as steel, aluminum, and copper shingles, are highly recyclable. Metal recycling facilities often accept metal roofing materials and process them into new metal products. Recycling metal reduces the need for mining raw materials, so metal roofing has a positive ripple effect!
TIP: Always check with your local recycling facilities or waste management authorities to see if they accept roofing shingles for recycling. Follow any specific guidelines for preparation and disposal. Remember, many roofing materials contain chemicals that can leach into the soil and groundwater.
What are the most environmentally friendly roofing materials?
If you want to help the planet with your new roof, consider each material’s sustainability, energy efficiency, recyclability, and environmental impact. Here are some of the most eco-friendly roofing options:
Metal Roofing
Metal roofing, typically made from steel, aluminum, or copper, is highly durable and recyclable. It often contains a significant percentage of recycled material. Even better, it can be recycled again at the end of your roof’s lifespan.
Metal roofs also improve your home’s energy efficiency because they reflect sunlight, reducing cooling costs.
Plus, they have a long lifespan, reducing the need for frequent replacements.
Recycled Shingles
Some roofing materials are made from recycled materials, such as recycled rubber or plastic shingles. These shingles often incorporate post-consumer waste, such as recycled tires or plastic bottles, and can be recycled again at the end of their lifespan. They provide an eco-friendly alternative to traditional roofing materials and help reduce waste sent to landfills.
Clay or Concrete Tiles
Clay or concrete tiles are made from natural materials that are abundant and locally sourced. They also provide thermal mass, which can help regulate indoor temperatures and reduce energy consumption. The “barrel”-style tiles are especially helpful as their curved shape allows better airflow under your roof, further cooling your home.
Plus, clay and concrete tiles have a long lifespan and can be recycled once the roof needs replacing.
Slate Roofing
Slate roofing is highly durable and long-lasting. The stone is sourced from quarries and does not require chemical processing during manufacturing.
Slate is recyclable and can be salvaged for reuse in other construction projects. Like clay, slate tiles provide excellent insulation and resist heat transfer.

Sustainable Roofing: Friendly to Planet Earth, Friendly for Your Home and Wallet
To find eco-friendly roofing material, consider factors such as durability, energy efficiency, recyclability, local availability, and compatibility with your climate and building design. In Florida, we often recommend metal or tile roofing. These help deflect the sun’s heat and keep your home cooler inside, reducing your AC usage and therefore your power bill. Plus, these materials usually have fewer toxic materials. And because they’re highly durable, you’ll get more out of your investment — and some cost savings as well!
