While Owens Corning Duration shingles are top-tier, reported customer complaints and field issues occasionally include premature granule loss, localized blistering from thermal shock, and shingle curling if attic ventilation is severely compromised. Additionally, improper fastener placement during installation can occasionally lead to wind-lift vulnerabilities. Working with a certified Platinum or Preferred contractor ensures correct installation practices and safeguards your warranty coverage.
