Asphalt Shingles & Health: Understanding Potential Risks

Asphalt shingles contain polycyclic aromatic hydrocarbon (PAH). This is a hazardous compound thought to have harmful effects on DNA structure. Asphalt may also contain carcinogens; however, as of 2010, more scientific research is needed to establish a direct correlation between long-term exposure and adverse health effects.

Roofing Shingles

• Asphalt shingles contain harmful contaminants such as PAHs. Rainwater that flows off rooftops may also contain toxic elements, such as lead and arsenic. However, according to the Centers for Disease Control and Prevention (CDC), more research is needed to determine concentration levels and toxicity effects on humans and animals.

Pulmonary Issues

• According to the CDC, asphalt fumes contain particulates and PAH structures. Long-term exposure to these compounds may cause pulmonary irritation and inflammation in workers in the asphalt industry.

Roofing Installation Hazards

• Due to high temperatures that are necessary during asphalt roofing installation, CDC studies indicate that workers in this field may have a higher risk of inhaling harmful compounds that could cause cancer and other respiratory issues.
