Owens Corning Platinum Preferred is the highest tier in the Owens Corning network, an invitation-only status held by roughly the top 1% of Owens Corning contractors, and uniquely among the major programs it requires the highest customer-satisfaction scores of any tier, not just training and insurance.
A Platinum Preferred contractor can register the Platinum Protection Limited Warranty, which provides lifetime coverage on materials, 50 years of transferable coverage, and 25 years of labor coverage, meaning Owens Corning will pay both for defective materials and for the labor to correct covered installation problems for a quarter century.
Because the warranty is manufacturer-backed and transferable, the protection survives a change of homeowner and does not depend on the original installer remaining in business. For a homeowner, this tier is the strongest assurance Owens Corning offers that both the product and the installation are covered.
