Generalized Effects of Unknown Chemical Contamination on Asphalt Shingles
1. Immediate Risks
-
Many chemicals (petroleum-based or industrial byproducts) can dissolve or soften the asphalt binder in shingles.
-
Even without knowing the specific substance, contamination often results in oily residue, surface staining, and premature granule loss.
​
2. Medium-Term Risks
-
Shingles may lose stiffness, blister, or warp as the binder continues to degrade.
-
Adhesive strips can fail, reducing wind resistance and increasing the chance of shingle blow-off during storms.
3. Long-Term Risks
-
Prolonged exposure to UV rays on compromised shingles accelerates cracking, curling, and brittleness.
-
Contaminants can migrate into the underlayment and roof decking, risking water intrusion, wood rot, or mold.
4. Inspection Importance
-
Because the exact chemicals are unknown, it’s impossible to predict specific reactions.
-
The safest approach is to document the condition of the roof quickly and have a professional inspection.
