Roof Warranty FAQ
01. What is an NDL warranty?
NDL stands for “No Dollar Limit.” It means the manufacturer will cover the full cost of repairs or replacement—materials and labor—if a problem covered under the warranty occurs, regardless of cost.
02. Do I still need maintenance if I have a warranty?
Yes! Most warranties require regular inspections and maintenance to remain valid. Neglecting upkeep can void your coverage.
03. How long do Grell Roofing, LLC warranties last?
We offer coverage options ranging from 15 to 30 years, depending on the roofing system, your needs, and the chosen warranty level.
04. What does the warranty cover?
Depending on the plan, coverage can include material defects, labor, hail damage, and high wind protection.
05. Is my warranty transferable?
In many cases, yes. Transferability depends on the specific Duro-Last® warranty you select. We can review your options during your consultation.
