Roofing shingles are not toxic to live under, but they do contain chemicals that need proper handling during installation and removal. Most shingles sold in the U.S. are asphalt shingles, which account for about 80% of all roofing projects according to industry data. While asphalt shingles are safe once installed on your roof, the materials and fumes during installation can pose risks to workers. Understanding what’s in your shingles and how to stay safe is important for homeowners and contractors alike.
What Are Shingles Made of?
Standard asphalt shingles contain fiberglass, asphalt, and granules made from stone or ceramic materials. According to RubyHome (2025), about 90% of asphalt roofs are made with fiberglass as the base layer. The asphalt acts as a waterproof binder, while granules protect the shingles from UV rays and weather.
Most of these materials are considered safe for homeowners once installed.

Are Installation Fumes Dangerous?
The main concern with shingle toxicity comes during installation and removal. Workers who handle hot asphalt or old shingles may breathe in fumes. These fumes can irritate the lungs and eyes. Proper ventilation, masks, and safety gear protect workers from these risks.
According to the U.S. Bureau of Labor Statistics, roofing remains the 5th highest fatality rate in construction, with 29.9 deaths per 1,000 workers. Most deaths come from falls, not chemical exposure. However, roofing injuries are projected to cost $2.8 billion by 2025 according to OSHA. Safety training and equipment are critical.
Safe Shingle Materials for Your Home
If you worry about toxins, metal roofing and premium shingles offer alternatives. Metal roofs last 40 to 80 years and contain no asphalt. Architectural asphalt shingles, which cost $4.50 to $8.25 per square foot according to RubyHome (2025), are thicker and may off-gas less than basic shingles.
Cool roofs with reflective coatings are also growing in popularity. These can reduce energy use by up to 16.6% and may contain fewer harmful chemicals. According to industry data, cool roofs are growing at about 6% annually.
Installation Safety Tips
- Hire licensed contractors with proper safety training.
- Ensure workers wear masks and gloves during installation.
- Keep children and pets away during roofing work.
- Open windows for ventilation if strong smells occur inside your home.
- Ask your contractor about low-VOC or eco-friendly shingle options.
The bottom line is simple: your finished roof is safe to live under. Asphalt shingles have been used on millions of homes for decades. The real risk is to workers during installation, not to you living inside. If you have concerns, ask your contractor about premium or eco-friendly materials, and always hire qualified professionals who follow safety rules.
