Owens Corning Roofing Systems: What the Warranty Actually Covers

An Owens Corning full system roof—installed with matching Owens Corning components rather than mixed materials—typically qualifies for extended manufacturer warranty coverage beyond the standard shingle-only warranty.

WHY “FULL SYSTEM” MATTERS

Manufacturer warranties are often written to apply only when every component—including shingles, underlayment, ventilation, starter strip, and ridge cap—comes from the same manufacturer and is installed according to their specifications.

Mixing brands or skipping components can quietly void extended warranty coverage without the homeowner realizing it until they need to file a claim.

WHAT EB CUSTOM EXTERIORS INCLUDES

At EB Custom Exteriors, we install Owens Corning full roofing systems where the project qualifies.

Every installation is also backed by our own 10-Year Limited Workmanship Warranty, which is separate from—and in addition to—the manufacturer’s warranty coverage.

MANUFACTURER WARRANTY VS. WORKMANSHIP WARRANTY — WHAT’S THE DIFFERENCE?

A manufacturer warranty covers defects in the roofing materials themselves.

A workmanship warranty, such as EB Custom Exteriors’ 10-Year Limited Workmanship Warranty, covers issues that result from the installation process.

These are two separate forms of protection, and together they provide greater peace of mind for homeowners.

DOES EVERY OWENS CORNING ROOF QUALIFY FOR THE SAME WARRANTY?

No.

Extended manufacturer warranty coverage depends on installing a qualifying Owens Corning full roofing system with matching components and following the manufacturer’s installation requirements.

No.

The manufacturer’s warranty covers the roofing materials, while the 10-Year Limited Workmanship Warranty covers installation-related issues. These protections work together but cover different aspects of your roofing project.

Often yes, especially when the damage is tied to the same wind or hail event as roof damage. We can document and include it in your claim.
