Short Answer
A roofing manufacturer certification means the manufacturer has verified that the contractor meets their standards for licensing, insurance, and installation training, and has authorized the contractor to offer enhanced warranty options on their products. The certification is issued by the manufacturer, not self-claimed by the contractor, and it can be verified with the manufacturer.
Detailed Explanation
Roofing manufacturers like Owens Corning, TAMKO, and CertainTeed create certification programs to identify contractors who install their products according to the manufacturer's specifications. These programs typically have multiple tiers, with the highest tier offering the most comprehensive warranty options. To earn and maintain certification, a contractor must meet requirements for proper licensing, insurance coverage, and installation training. The manufacturer verifies these requirements and may conduct periodic reviews. When a certified contractor installs a complete roofing system from that manufacturer, the homeowner may be eligible for enhanced warranty coverage — including non-prorated terms and workmanship backing — that is not available through non-certified contractors.
Why It Matters
Manufacturer certification directly affects the warranty coverage available to the homeowner and provides third-party verification of installation quality.
