Owens Corning Roofing Warranties: A Comprehensive Guide

Owens Corning offers multiple warranty options for asphalt shingle roofs, designed to protect homeowners from manufacturing defects and, in some cases, workmanship. This guide explains the main warranty types, what they cover, how to qualify, transferability, and best practices to maximize protection. Readers will gain a clear understanding of how these warranties work and how to navigate claims when needed.

Overview Of Owens Corning Roofing Warranties

Owens Corning provides two primary warranty families for asphalt shingles: the Shingle Limited Warranty and the System Warranty. The Shingle Limited Warranty covers manufacturing defects in the shingles themselves, while the System Warranty extends coverage to additional roof components when installed with a participating OC contractor. The eligibility, duration, and transferability vary by product line and installation conditions. Homeowners should review the specific warranty certificate that accompanies their shingle product for exact terms.

Shingle Limited Warranty

The Shingle Limited Warranty is the core coverage for Owens Corning shingles. It typically covers manufacturing defects in the shingles for the life of the product, with certain prorated or non-prorated portions depending on the line and date of installation. Key elements often include:

• Coverage Scope: Defects in shingles that affect performance or appearance due to manufacturing issues.
• Duration: Varies by product line; many shingles offer a lifetime coverage, subject to terms and conditions.
• Prorated vs. Non-Prorated: Some lines transition from non-prorated to prorated portions over time, affecting claim amounts in later years.
• Color Fading: Some warranties address cosmetic issues like fading, but typically with stringent criteria.

Important notes:

• Proper Installation: The warranty hinges on installation by a qualified contractor following OC’s installation guidelines.
• Ventilation and Maintenance: Adequate attic ventilation and routine maintenance are required to keep coverage active.
• Exclusions: Damage from improper installation, asphalt film defects caused by site conditions, abusive use, or acts of nature may be excluded.

System Warranty

The System Warranty adds coverage when the roof is installed with a complete system of Owens Corning components and a participating contractor. This program aims to guarantee the roof system’s performance as a whole, not just individual shingles. Typical features include:

• Broader Coverage: Includes components such as underlayment, fasteners, and related accessories sold and approved by Owens Corning.
• Workmanship Considerations: Some System Warranty options provide protections tied to the installation quality when performed by an OC Preferred Contractor.
• Transferability: The warranty can often be transferred to a new homeowner under specified terms and timeframes.
• Documentation: Registration or proof of purchase and contractor details are commonly required to activate or maintain coverage.

Important notes:

• Contractor Qualification: Only certain contractors affiliated with Owens Corning are eligible to offer System Warranty coverage.
• Maintenance And Alerts: As with the Shingle Limited Warranty, routine maintenance and adherence to OC guidelines are essential.
• Limitations: The System Warranty may have limits on coverage amounts and may exclude certain conditions or damages.

Transferability And Registration

Warranty transferability is a valuable feature for homeowners planning to sell. Owens Corning generally supports transferring the warranty to a new owner, subject to specific conditions, such as:

• Notification: The transfer must be initiated within a defined period after ownership changes.
• Documentation: The new owner may need to complete registration, and the original installer’s details may be required.
• Limitations: Some warranties may have different transfer terms depending on the product line and date of installation.

For buyers or sellers, confirming transfer options and timelines during the closing process helps preserve warranty benefits.

What Voids An Owens Corning Warranty?

Warranties can be voided by actions or situations outside the manufacturer’s control. Common factors that may void coverage include:

• Improper Installation: Installing shingles or components in violation of OC installation instructions.
• Unauthorized Repairs: Repairs performed by non-approved contractors or using incorrect components.
• Alterations: Modifications to the roof that do not follow OC guidelines.
• Neglected Maintenance: Failure to address known issues such as inadequate ventilation or drainage problems.
• Excessive Weather Damage: Damages from extreme events may fall under homeowners’ or other insurance and may be excluded from the warranty.

Homeowners should keep meticulous records of installation details, product serials, and service notes to support any potential claim.

Filing a Claim

When a potential warranty issue arises, follow these steps to file a claim effectively:

• Document The Issue: Take clear photos of the defect and note the roof location and date of discovery.
• Verify Coverage: Check the warranty certificate or OC’s official warranty portal for coverage specifics and required documentation.
• Contact The Installer: Start with the affiliated contractor who performed the installation, as they can guide the claim process or initiate it on your behalf.
• Follow Up: Keep copies of all correspondence and maintain a timeline of inspection and repair steps.

OC products typically require inspection by a qualified professional to validate a defect claim, with timelines varying by warranty type.

Maintenance Tips To Preserve Warranty Coverage

To maximize warranty protection, homeowners should implement regular roof maintenance and inspections. Practical steps include:

• Inspect After Severe Weather: Check for damaged shingles, loose fasteners, and signs of granule loss after storms.
• Clean Debris: Remove leaves and debris from gutters and valleys to prevent water buildup.
• Ventilation Check: Ensure attic ventilation remains adequate to reduce heat and moisture buildup that can affect shingle performance.
• Professional Inspections: Schedule periodic roof evaluations by OC-approved contractors to catch issues early.

Cost, Coverage, And Limitations At A Glance

While warranty details vary by product line and installation date, homeowners should expect:

• Shingle Coverage: Defects in shingles with duration tied to product terms; non-prorated and prorated periods may apply.
• System Coverage: Extended protection for roof components and, in some cases, workmanship when installed by an OC Preferred Contractor.
• Transferability: Options available under specified conditions and timeframes.
• Exclusions: Common exclusions include improper installation, alterations, and non-covered damages.
