Are Roofing Glue Fumes Toxic?

Are you concerned about the toxicity of roofing adhesive fumes? Numerous issues may be avoided by being aware of the hazards linked with roofing glues.

When heated, asphalt and roofing glue containing neoprene release harmful gasses. The majority of roofing adhesives emit harmful gasses when heated.

I’ll go into great detail below as to why some roofing adhesive constituents emit hazardous fumes.

Why Do Heating Roofing Glues Make Them Toxic?

The following components are common in roofing glues and release harmful vapors when heated. Make sure to do a thorough study before choosing a roofing glue.


Asphalt is a petroleum substance used in roofing, road paving, siding, and concrete constructions, and it exposes around 500,000 employees to fumes. Skin rashes, headaches, coughing, sensitization, decreased appetite, exhaustion, throat and eye irritation, and skin cancer are among the health impacts of asphalt fume exposure.

Refined crude oil is used to make a variety of compounds, including coal tars, asphalt, and modified bitumen. They all produce a lot of cancer-causing polycyclic aromatic hydrocarbons (PAH). When exposed to PAHs regularly released from tars and asphalt, road workers and roofers have a greater chance of acquiring cancer and other health issues.

Consumers are still determining the danger magnitudes. However, breathing in bitumen and asphalt fumes is not good for your health. According to the National Institute for Occupational Safety and Health, studies of roofers [and employees who are highly exposed to asphalt or modified bitumen] reveal an increase in liver, digestive system, brain, lung, and bladder cancers.

Because of their very cautious stances, the CDC and other government organizations cannot formally proclaim bitumen and asphalt to be carcinogenic without convincing proof. The CDC states that the tars will continue to be potential carcinogens. Cigarettes perfectly illustrate how the American government refuses to acknowledge the “writing on the wall.”

For many years, research connected smoking cigarettes to developing lung cancer. However, it took decades for the government to acknowledge this formally. Usually, there is overwhelming and conclusive evidence by the time the government is ready to pronounce a substance dangerous.

Modified bitumen still contains polycyclic aromatic hydrocarbons (PAH) while being less hazardous than coal tar. Numerous investigations have shown the carcinogenicity of applying laboratory-produced asphalt roofing fume condensates to rats.


Neoprene can release harmful hydrogen chloride into the air when heated. Typically, neoprene is secure, and Neoprene production also generates dangerous airborne pollutants.

Numerous individuals who have skin sensitivities, such as dermatitis, may have allergic responses after wearing neoprene-containing clothes. Dialkyl thioureas, named the year’s allergen in 2009, is to blame for this.

It causes a lot of skin responses. Most individuals generally believe neoprene is safe to wear unless they already have an allergy to it.


The solvent xylene is often used in construction adhesives, and it is dangerous to breathe in xylene vapors.

When you breathe in its fumes, xylene enters your body quickly, according to the California Department of Health Services. It may also enter your body via your skin, especially if there is prolonged contact. Your brain system, respiratory system, and skin are the most often impacted systems by xylene overexposure.
