Everyone quotes warranty numbers. Almost nobody explains the mechanics that decide whether you actually have coverage.
Your roof carries two separate warranties from two separate parties. Here is what each one covers, what quietly cancels them, and how to check before you sign.
Your roof has two warranties, and they cover different failures.
Two documents, two issuers, two claim processes. Most homeowners think they have one.
A manufacturer-backed system warranty ranks above any contractor's own warranty for one reason: it survives the contractor. If a roofing company closes, changes hands, or simply stops answering the phone, a warranty backed by Owens Corning or GAF is still honored. A contractor's warranty is only worth as much as the contractor still being in business, and that is as true of ours as it is of anyone's.
The manufacturer's system warranty is issued by the shingle maker. It covers their products, and at the enhanced tiers it also covers the installation of those products. You claim against it with the manufacturer, not with the roofer, and the manufacturer decides.
A contractor's workmanship warranty is issued by the roofing company and covers that company's own work — the flashing detail, the fastening pattern, the penetrations they cut and sealed. You claim against it with the contractor, and the contractor decides.
Those are separate pieces of paper with separate claim routes, and a failure that one covers the other usually does not. When someone tells you "the roof is under warranty," the useful follow-up question is: which one, and where is the document?
The certification tier decides which warranty you can even be offered.
This is the mechanic that gets left out of every sales conversation.
Enhanced and system warranties are gated by the installing contractor's standing in the manufacturer's contractor program. This is not a matter of negotiation or effort. A contractor at a lower tier physically cannot register the higher warranty, no matter what they promise on the proposal, because the manufacturer's system will not accept the registration.
GAF publishes this rule openly. On GAF's own residential warranty resources, the Silver Pledge Limited Warranty is stated as available through GAF Certified Plus or Master Elite contractors only. That is GAF's published program rule, and it is the clearest public illustration of how the gating works across the industry.
Atrium holds Owens Corning Platinum Preferred, the top tier of the Owens Corning contractor network, which makes the enhanced Owens Corning system warranty available on our installs. We also hold GAF Certified Plus, which makes the GAF Silver Pledge available. These system warranties cover material and, at these tiers, workmanship, and they are registered with the manufacturer in your name.
| Certification Atrium holds | System warranty we can register |
|---|---|
| Owens Corning Platinum Preferred | Enhanced Owens Corning system warranty, available at Platinum Preferred standing |
| GAF Certified Plus | GAF Silver Pledge, available at Certified Plus standing |
| TAMKO Pro Platinum | TAMKO MasterShield Enhanced Limited Warranty, available at TAMKO Pro Platinum standing |
| Atlas Pro Plus | Atlas Signature Select Roofing System Limited Warranty, available at Pro Plus standing |
| Malarkey Emerald Pro | Malarkey Certified Pro Warranty, available at Emerald Pro standing |
A few caveats worth stating plainly, because they are the kind of detail that decides a claim. TAMKO's enhanced warranty availability is additionally gated by which TAMKO shingle line is installed, so it is not automatic across every TAMKO product. The Atlas Signature Select warranty requires a complete Atlas system — shingle, underlayment, and accessories — rather than the Atlas shingle alone. And the Malarkey warranty above requires a complete Malarkey Secure Choice™ roof system, shingles installed together with Malarkey's own accessories, not the shingle by itself.
The practical instruction for a homeowner: verify the contractor's tier on the manufacturer's own contractor locator before you sign. Certification standing is live and can lapse, and the badge on the truck is not evidence of anything.
Four things that quietly leave you with no warranty at all.
None of these announce themselves. You find out at claim time.
Enhanced warranties are not automatic. The installing contractor has to register them with the manufacturer after the job closes out, and a warranty that was never registered is not a warranty you hold. Malarkey puts a hard clock on it: Malarkey requires the warranty to be purchased and registered by the certified contractor within 45 days of installation, and coverage is not valid until Malarkey accepts that registration. GAF gives you the homeowner-side way to check that it happened: GAF tells homeowners to contact GAF directly if the warranty and registration copy has not arrived within 60 days of the installation being completed. Those are two manufacturers' own specific rules, not a universal industry deadline — every manufacturer writes its own. Read yours, and ask for the registration confirmation document by name rather than assuming it happened because someone said it would.
This one catches people who did everything right. Malarkey states that coverage does not take effect until all payments relating to the warranty have been made in full — to Malarkey, to the contractor, and to the material supplier. So a roof can be correctly installed, on a fully eligible system, by a properly certified contractor, and still carry nothing — because a balance sat unpaid somewhere in the chain you never saw. You cannot audit a contractor's supplier account, but you can ask for written confirmation that the warranty is active and accepted, rather than merely submitted.
Every manufacturer's enhanced warranty requires a specified minimum set of that manufacturer's own components installed together — not simply their shingle with whatever else was on the truck. Substituting a third-party underlayment, starter course, ridge cap, or ventilation product is one of the most common ways a homeowner ends up outside the warranty they believed they bought. Which components are required differs by manufacturer and by warranty tier, so the answer that matters is the one written on your proposal, naming the specific products going on your roof.
A contractor's own warranty is a promise from a business, and businesses close, sell, and stop answering the phone. That is the whole reason the manufacturer document ranks first — and it applies to us exactly as much as to anyone else. If the only paper you hold is a contractor warranty, you are holding a promise rather than a warranty.
Two coverage mistakes come up often enough to call out directly. Poor attic ventilation is a published condition of most manufacturer warranties — our attic ventilation explainer covers how to tell if your attic is actually breathing. And when the damage is from hail or a storm, that is an insurance claim first, not a warranty claim — our insurance claims guide walks through how a Texas hail claim actually runs.
What a warranty is actually protecting — and why the number grows
A warranty does not stop your roof wearing out on schedule. It protects you against a defect or an installation error forcing a premature replacement.
Which reframes the question. The figure that matters is not what your roof cost. It is what replacing it would cost in the year the failure actually shows up — and that number moves.
How this was calculated, and what it is not. The starting band is our installed rate for laminated architectural shingles, $11,900 to $15,000, applied to a stated editorial assumption of 25 roofing squares for illustration — that square count is an assumption for the diagram, not a figure from our rate sheet. It is escalated at 3.6% per year, derived from the U.S. Bureau of Labor Statistics Producer Price Index for Asphalt Shingle and Coating Materials Manufacturing (series PCU3241223241222, index Jun 1984 = 100), which rose from a low of 93.60 in July 1987 to 375.52 in June 2026 — a compound annual rate of roughly 3.6% over that span.
That is a historical materials-index rate, not a forecast. It measures materials rather than labor, and actual future roofing costs will differ from this curve, possibly by a lot. We are showing you the shape of the problem — a premature failure in year fifteen is priced in year-fifteen dollars — not predicting your bill.
Atrium's own warranties
The manufacturer's system warranty comes first. Ours is the layer underneath it.
Atrium backs every roof replacement with a written 10-year workmanship warranty. It is non-prorated, so coverage in year ten is identical to year one, and it is fully transferable to the next owner. If a covered installation defect appears, we cover the labor and the materials to correct it.
The warranty covers the roof replacement we performed. It is our installation of your new roof system that carries the ten years.
It covers our installation, and that is all it covers. It is not insurance and it does nothing for hail, wind, or anything else an insurance claim would handle. The manufacturer's warranty on the shingles themselves is a separate document.
How a replacement runsSystem warranties attach to a full system install, so on a repair the contractor warranty is what there is, and it is presented directly.
Every repair Atrium performs carries a written 12-month workmanship warranty. It covers the workmanship of the repair we did. If that repair does not hold the way it should, we come back out and put it right.
One thing worth being clear about: the warranty covers the repair we performed, not the condition of the rest of your roof. If your roof is twenty years old and we reflash a chimney, the chimney work is what we stand behind. The rest of the roof keeps aging at its own pace, and we will tell you honestly where it stands.
It is not insurance. It does nothing for storm, hail, or wind damage, which is what an insurance claim is for.
