Understanding and Managing Tobacco Juicing on Asphalt Shingles

What Is “Tobacco Juicing”?

“Tobacco Juicing” is a naturally occurring phenomenon that appears as a brown sticky substance on asphaltic roofs and surrounding areas under specific climatic conditions. This substance is not due to a manufacturing defect or a problem with the asphalt. It typically occurs when a roof is exposed to intense sun combined with excessive night moisture but a prolonged lack of rain.

Specifics of Tobacco Juicing

The tobacco juicing substance results from water-soluble leaching from the oxidized surface of exposed asphalt. It can be seen on all asphalt-based products such as cements, coatings, shingles, as well as low-slope base and cap sheets. A similar phenomenon can occur in smog areas where air pollution accumulates on the roof surface, indicating the environmental nature of this issue.

• Environmental Contamination: Pollution and particulate matter from the air settle on the roof, especially in smoggy areas. The combination of air pollutants, nighttime dew, and lack of rain leads to the appearance of tobacco juicing.
• Residue Accumulation: This residue can accumulate until the surfaces are washed or significant rainfall occurs. It may drip off shingles and stain siding but does not affect the performance of the roof.

Where and Why Does It Occur?

Tobacco juicing is most commonly reported in the Southwest and West, where intense sunlight, heat, air pollution, and lack of rain are prevalent. However, it can occur in any region with the right conditions.

Affected GAF Shingles

All GAF shingles can be affected by tobacco juicing. It is an asphaltic and environmental phenomenon, not a manufacturing by-product, and can occur with shingles from any manufacturer.

Remedies for Tobacco Juicing

If an objectionable amount of residue appears, a simple and effective method to combat it is to hose down the roof during prolonged dry periods. This can help wash away the accumulated residue and maintain the roof’s appearance.

Warranty Information

Tobacco juicing is a cosmetic condition and is generally temporary. It does not affect the water-tightness or longevity of the roof system. Therefore, the GAF Shingle Limited Warranty against manufacturing defects remains in full force and effect per its terms and conditions.

Conclusion

Tobacco juicing is a temporary, cosmetic issue that occurs due to environmental factors. While it may affect the appearance of your roof, it does not impact the performance or longevity of the shingles. Regular hosing during dry periods can help manage this phenomenon.
