Warranty Coordination in Oklahoma City, OK.

What Each Manufacturer Requires

GAF EverGuard Extreme warranties (TPO and EPDM, 20-year NDL tier) require annual maintenance by a GAF-credentialed contractor with a maintenance report submitted to GAF within 90 days of service. The report format is GAF-specified — a generic inspection report does not satisfy this requirement. We submit directly to GAF's warranty management system. GAF is one of the most common systems on OKC commercial buildings constructed between 2000 and 2015.

Carlisle SynTec SureCast and Sure-Weld warranties require similar annual maintenance by a Carlisle-approved contractor. Carlisle's maintenance standard requires a documented test of every accessible seam — not just visual inspection — and specific drain clearing documentation. We follow Carlisle's published maintenance protocol for each warranty tier. Carlisle systems are common on medical office buildings throughout the OKC health corridor.

Johns Manville JM PremiumPlus warranties require maintenance at the frequency specified in the warranty document (which varies by tier — some are annual, some biannual) with documentation submitted to JM's warranty tracking system. JM also requires that any repairs during the warranty period be performed by a JM-credentialed contractor and documented against the specific warranty number. We carry JM credentials and file repair documentation under each building's registered warranty.

Sika Sarnafil and Versico maintain separate warranty programs under the Sika group umbrella. we install both legacy programs and file maintenance documentation under whichever warranty number the building's roof was registered under. For buildings where the original warranty program has transferred between ownership cycles, we trace the warranty registration and verify the maintenance documentation path before the first service.

Repair Work During the Warranty Period

Any repair performed on a warranted roof during the warranty period must follow the manufacturer's detail standard and be documented as a manufacturer-compliant repair. This is where OKC buildings get into trouble after hail events: a building owner calls the first available contractor after a storm, the repair is physically sound but does not use the correct materials or flashing detail for that manufacturer's system, and the repair holds for two or three seasons. When the roof fails elsewhere and the owner files a warranty claim, the manufacturer's field inspector finds the non-compliant prior repair and excludes the area surrounding it from coverage.

We perform repairs on warranted systems under the applicable manufacturer's repair standard and document every repair against the building's warranty number. If we take over warranty coordination on a building that already has non-compliant prior repairs — a common situation after storm seasons when uncredentialed contractors do rapid dry-in work — we assess those repairs, note them in the condition record, and advise the owner of the warranty exposure. We cannot retroactively make prior repairs compliant, but we can document the current condition accurately so the owner knows exactly where the coverage risk is.

When a Claim Is Needed

When a manufacturer warranty claim is warranted — typically a membrane failure at a field seam or a flashing failure at a manufacturer-detailed transition — we coordinate the claim process. We document the failure, identify whether it falls within the warranty coverage scope, notify the manufacturer's warranty department, and schedule the manufacturer's field inspection. We participate in the field inspection and present the maintenance record.

In Oklahoma City's hail environment, field inspections after a storm event sometimes involve the manufacturer attempting to attribute warranty-claim failures to impact damage rather than workmanship defect — impact damage is generally excluded from manufacturer warranties while workmanship and material defects are covered. Our condition record and maintenance documentation establish the pre-storm state of the affected membrane, which is the documentation that supports the workmanship-defect argument when the claim is contested.

Frequently asked questions

Our roof has a manufacturer warranty but we have never done documented maintenance. Are we exposed?

Likely yes. Most NDL manufacturer warranties specify that failure to perform documented annual maintenance voids or reduces coverage. The degree of exposure depends on the manufacturer and the warranty tier. In Oklahoma City's claim environment — where hail events test warranties regularly — this exposure is not theoretical. We can review your warranty document, assess the maintenance history, and tell you specifically what the exposure is and whether there is a path to recover any coverage.

Can any roofing contractor perform warranty maintenance?

No. Warranty maintenance must be performed by a contractor holding current credentials with that specific manufacturer. we install GAF, Carlisle SynTec, Johns Manville, Sika Sarnafil, and Versico — the five manufacturers whose systems cover most of the OKC commercial building inventory. We can maintain any of those systems regardless of who originally installed it.

What if a non-credentialed contractor already made repairs on our warranted roof after a storm?

Document it, assess the exclusion exposure, and establish a compliant maintenance protocol going forward. Non-compliant repairs do not automatically void an entire warranty — they create a specific exclusion around the repair area. We identify every non-compliant prior repair, note the exclusion in the condition record, and prevent additional exclusions from accumulating through our going-forward maintenance program.

How long do manufacturer warranties last on Oklahoma City commercial roofs?

Standard NDL warranties on 60-mil TPO and EPDM from major manufacturers run 20 years. 80-mil systems from some manufacturers carry 25-year NDL terms. PVC systems run 20-25 years depending on manufacturer and mil thickness. Impact-rated systems installed with qualifying cover boards — which we specify on every OKC replacement project for hail-resistance qualification — do not typically alter warranty term, but the cover board specification affects whether the assembly qualifies for impact-rated claims. We track the specific term and coverage structure for every warranted building in our program.
