Commercial Roof Warranty Guide
Manufacturer vs workmanship, NDL warranties, and what keeps yours valid.
Commercial roof warranties come in two types: a manufacturer warranty covering materials (typically 10–30 years and requiring certified-contractor installation) and a workmanship or labor warranty covering the installation itself (typically 2–5 years). A No Dollar Limit (NDL) warranty is the gold standard — it covers both materials and labor with no cap. One key point for North Texas: hail damage is generally a separate insurance claim, not a warranty claim.
The two warranties on your roof
- Manufacturer (material) warranty — covers the membrane/system for 10–30 years; usually requires a manufacturer-certified installer
- Workmanship (labor) warranty — covers installation defects, typically 2–5 years from the contractor
- NDL (No Dollar Limit) warranty — the premium manufacturer warranty covering both material and labor with no dollar cap
What keeps a warranty valid
- Installation by a manufacturer-certified contractor to spec
- Documented maintenance and periodic inspections
- Prompt repair of damage and no unauthorized alterations or added rooftop equipment
- Keeping records — inspection reports and repair documentation
Hail is insurance, not warranty
A common misunderstanding: warranties cover material defects and workmanship, not storm damage. When DFW hail damages your roof, that's a property-insurance claim, not a warranty claim — which is why documented post-storm inspections matter. A well-maintained roof with valid warranties and good inspection records is far easier to insure and to claim on.
