A commercial roof warranty reads like protection on the day the contract gets signed. Read the exclusions page first, and the protection shrinks fast, especially on a low-slope roof carrying New England snow load and freeze-thaw cycles.
Three things decide whether a claim gets paid:
- Which warranty type was signed (there are 3 warranty types)
- Whether the failure counts as a covered defect (is it covered?)
- Whether the maintenance records exist to prove upkeep (how to avoid getting denied)Â
Here’s the breakdown:
The Three Warranty Types
- Material-Only Warranty. The manufacturer replaces defective products. The building owner covers removal and labor, usually 50 to 70 percent of the total job cost.
- Contractor Workmanship Warranty. The installer’s own guarantee against installation and flashing errors, typically 1 to 5 years, backed by the contractor rather than the manufacturer.
- No Dollar Limit (NDL) System Warranty. The manufacturer backs 100 percent of labor and material for an approved system, installed and certified by an authorized contractor. The strongest of the three, and the one most owners assume they already have.
What Gets Covered
- Membrane failures caused by premature cracking, splitting, or defective manufacturing
- Flashing and seam failures tied to installation, when the install was done by a certified contractor
- Wind performance up to the system’s rated speed, not a number above the rating
Where Claims Get Denied
Weather beyond the rating: Wind above the rated speed and storm debris fall outside standard coverage regardless of roof age.
Interior damage: Ruined ceiling tiles, inventory, or electronics get covered by the building’s property insurance, not the roof warranty. The two are separate policies with separate adjusters.
Unauthorized penetrations: An HVAC repair, a solar array, or a telecom install added after the roof went on, without manufacturer sign-off, voids coverage for the area around the new penetration.
Missed maintenance records: Most manufacturers require documented, dated inspections, often twice a year. If you don’t have a strong record, you’ll often get a denied claim, even when the defect is real.
The New England Line Item Most Warranties Skip
Flat and low-slope commercial roofs in NH and MA carry snow load and ice that most manufacturer warranty language never fully addresses. A blocked or frozen drain, or water standing more than 48 hours after a storm, sits outside coverage as a maintenance failure.
Property owners who assume winter damage falls under the warranty find out otherwise during the claim.
