Residential warranty disaster
Asphalt shingles
The incident: A roofing contractor installed premium shingles on a major re-roof project. Six months later premature wear appeared, and the manufacturer denied the warranty claim because the contractor couldn't prove temperature compliance.
Temperature: Estimated 38-42F, below the 40F minimum
Manufacturer: Major shingle manufacturer
Lesson: No timestamped weather documentation means no defensible warranty record.
