Owens Corning warranty for roofing, siding & insulation
The short version
Owens Corning doesn't cover everything, but keeps insulation and workmanship covered for life. That full coverage is the same as most of the 7 brands we compared, which typically cover nothing in full. You don't need to register to get this coverage.
From Owens Corning's published warranty, checked October 2026.
