Holden Roofing has been recognized as a Platinum Preferred Contractor through leading shingle manufacturer, Owens Corning. While many shingle manufacturers offer contractor programs open to any roofer, membership in the Platinum Preferred contractor program is by invitation only. Contractors must submit a comprehensive safety program and be financially stable to even be considered for this program. Through this program, Holden Roofing is one of the few contractors in the United States that can offer the Platinum Promise Limited warranty from Owens Corning.
