Material warranty
The manufacturer replaces defective material. Labor to install it is usually not included at this level.
Commercial Roof Warranties, Explained, at a glance
A commercial roof carries two separate warranties. The manufacturer warrants the materials, and on an NDL warranty the labor to fix a covered defect. The contractor warrants the workmanship — the seams, flashings and details. John Beal Roofing carries manufacturer certifications and backs its own workmanship with a lifetime warranty.

The Details
What To Look At
NDL warranty
No Dollar Limit. The manufacturer covers material and the labor to repair covered defects, up to the term. It requires a certified installer.
Workmanship warranty
The contractor's own coverage on seams, flashings and details — which is where roofs actually leak.
What voids it
Unauthorized penetrations, other trades on the roof, ponding left uncorrected, and missed maintenance.
Maintenance programsTransferability
Selling the building? Many warranties transfer once, sometimes for a fee, usually within a filing window.
Registration
A warranty that was never registered under your address does not exist. We file it and give you the copy.
The practical takeaway: a 20-year membrane on a roof installed by an uncertified crew is a 20-year material warranty on a roof that will leak at the flashings in year four, and the flashings are the contractor's problem, not the manufacturer's.
We hold the certifications, register the coverage under your building, and back the workmanship ourselves with a lifetime warranty on qualifying work.

We Put This In Writing
Every commercial inspection we run ends with a written record: what we found, photographed, ranked by urgency, with a real number attached.
It costs nothing and it is yours whether or not we do the work. Owners use ours to sanity-check other bids all the time, and that is fine by us.
Common Questions
Does my warranty cover hail damage?
No. Storm damage is an insurance matter, not a warranty matter. We document it for the claim.
Does adding a satellite dish or new HVAC void my roof warranty?
It can, if the penetration is not flashed by a certified contractor. Call us before another trade cuts the roof.
Do I have to maintain the roof to keep the warranty?
Almost always yes. Most manufacturer warranties require documented periodic inspection and maintenance.
Can a warranty transfer to a new owner?
Usually once, often with a fee and a deadline after closing. Check the certificate before the sale closes.
