3 Types of Roofing Warranties
Before comparing brands, understand the three fundamentally different warranty types. Most homeowners conflate them, which leads to unpleasant surprises at claim time.
- ✓ Covers manufacturing defects
- ✓ Curling, cracking, granule loss
- ✗ Material cost only, no labor
- ✗ Usually prorated after 10 years
- • No installer requirements
- ✓ Covers material AND labor
- ✓ Backed by manufacturer
- ✓ Survives contractor bankruptcy
- ! Requires certified installer
- ! Must use full accessory system
- ✓ Covers installation errors
- ✓ Leaks from improper flashing
- ✗ Only as good as the company
- ✗ Worthless if contractor closes
- • Varies wildly by contractor
Key insight: A manufacturer material warranty without workmanship coverage is like car insurance that covers engine defects but not collision. Most roof failures are installation-related, not material defects.
Brand Warranty Comparison
Here is a side-by-side comparison of warranty tiers across all three major manufacturers.
| Feature | GAF | Owens Corning | CertainTeed |
|---|---|---|---|
| Basic material-only | Standard (prorated after 10yr) | Standard (material only) | Standard + SureStart (10yr non-prorated, no labor) |
| Entry system warranty | System Plus (2yr workmanship, 3+ accessories) | Preferred Protection (10yr workmanship) | SureStart PLUS (labor, full system required) |
| Mid-tier system | Silver Pledge (Master Elite, 10yr workmanship) | -- | 4-Star (SELECT ShingleMaster, 15yr workmanship) |
| Top tier | Golden Pledge (25yr workmanship + tearoff) | Platinum Protection (lifetime workmanship) | 5-Star (25yr workmanship + tearoff) |
| Wind add-on | WindProven (unlimited wind speed) | -- | -- |
| Required installer (top tier) | Master Elite (top 2%) | Platinum Preferred | SELECT ShingleMaster |
| Transferable | Yes, once, within 60 days, $50 fee | Yes, once, within 60 days, $75 fee | Yes, once, within 60 days, $100-150 fee |
GAF Warranty Tiers
GAF is the largest shingle manufacturer in North America. Their warranty structure has five levels, each adding incremental protection.
Standard Limited Warranty
Material defects only. Prorated after 10 years. Any installer qualifies. This is what you get by default when no certifications are involved.
System Plus
Adds 2 years of workmanship coverage by GAF (not the contractor). Requires 3 or more GAF accessories (starter, ridge cap, underlayment, etc.).
Silver Pledge
Requires a GAF Master Elite contractor. Adds 10 years of workmanship coverage backed by GAF, not the contractor. This is the sweet spot for most homeowners.
Golden Pledge
GAF's premium warranty. 25 years of workmanship plus 25-year coverage for tear-off costs. Only available through Master Elite contractors. The gold standard for asphalt shingle warranties.
WindProven
Unlimited wind speed warranty with no maximum mph limit. Add-on available when using 4 specific GAF accessories and LayerLock technology shingles (Timberline HDZ). No other manufacturer offers this.
Owens Corning Warranty Tiers
Owens Corning uses a simpler three-tier system. Their Platinum Protection is arguably the strongest top-tier offering because it includes lifetime workmanship coverage.
Standard
Material defects only. No labor coverage. Any installer qualifies.
Preferred Protection
Requires an OC Preferred Contractor. Adds 10 years of workmanship coverage.
Platinum Protection
Requires a Platinum Preferred Contractor. Lifetime workmanship coverage -- the strongest workmanship offering among the big three. Also includes lifetime non-prorated material coverage.
CertainTeed Warranty Tiers
CertainTeed has the most granular tier system with five levels. Their SureStart non-prorated period gives an early-years advantage, but the labor gap in the base tiers is important to understand.
Standard
Basic material coverage. Prorated from day one.
SureStart
Non-prorated material coverage for the first 10 years. No labor coverage. This is better than GAF Standard but still does not cover installation costs.
SureStart PLUS
Adds labor coverage to SureStart. Requires a full CertainTeed accessory system. This is where CertainTeed warranties start to become competitive with GAF System Plus.
4-Star
Requires a SELECT ShingleMaster installer. 15 years of workmanship coverage. Comparable to GAF Silver Pledge.
5-Star
CertainTeed's top tier. 25 years of workmanship coverage plus tear-off cost coverage. Comparable to GAF Golden Pledge. Requires the highest-level CertainTeed certification.
What Is NOT Covered by Any Warranty
These exclusions apply to virtually all roofing warranties regardless of brand or tier.
Hurricanes, tornadoes, hail, earthquakes, and lightning. These are homeowner's insurance claims, not warranty claims.
If attic ventilation does not meet manufacturer specs, the entire warranty can be voided.
Walking on the roof (satellite dish installers, HVAC techs, etc.) voids coverage for damaged areas.
Color variations, algae staining, minor granule loss that does not affect function.
Gradual deterioration consistent with the product's age is not a manufacturing defect.
Foundation settling, truss uplift, or other structural shifts that stress the roofing system.
Water damage to interiors, mold, lost income -- no manufacturer pays for downstream damage.
Pressure washing, painting, adding rooftop equipment, or non-certified repairs.
Prorated Depreciation: What You Actually Get Paid
Most homeowners are shocked by how little a prorated warranty actually pays out. Here is a realistic example of how proration works.
Scenario: Year 20 claim on a 30-year prorated warranty
On a $12,000 material defect at year 20, the manufacturer pays about $6,000 for materials. You pay $6,000 for materials plus $8,000-$15,000 for labor. The "30-year warranty" covers roughly 25-30% of the total repair cost.
Coverage Depreciation Over Time (Typical Prorated Warranty)
Non-prorated period (years 1-10) followed by straight-line proration. Actual schedules vary by manufacturer.

Your Estimated Warranty Coverage
Common Warranty Voiders (Ranked)
These are the most frequent reasons manufacturers deny claims. The ranking is based on industry adjuster reports.
High Nailing
Nails placed above the manufacturer's nailing strip. This single issue is the number one reason for warranty claim denial. The shingle tabs are not secured and blow off in wind.
Inadequate Ventilation
Insufficient intake or exhaust ventilation causes heat and moisture buildup that degrades shingles from underneath. Manufacturers require specific NFA (Net Free Area) ratios.
Unauthorized Repairs
Having a non-certified contractor perform repairs on a system warranty roof can void the entire warranty. Always contact the original installer or the manufacturer first.
Pressure Washing
Pressure washing strips protective granules and drives water under shingles. No manufacturer allows this cleaning method.
Mixed Ventilation Types
Combining ridge vents with powered attic fans or gable vents can short-circuit airflow and void the warranty. Pick one exhaust method and stick with it.
No Registration Within 60 Days
Some enhanced warranties require registration within 60 days of installation. Without registration, coverage defaults to the basic tier.
Painting Shingles
Painting or coating shingles alters their UV reflective and moisture-shedding properties. Always voids the warranty.
Red Flags in Warranty Fine Print
Watch for these deceptive or misleading warranty terms before signing with any contractor.
"Lifetime" warranty
In the roofing industry, "lifetime" means 40-50 years, not the rest of your life. Always find the actual term in the fine print.
Ventilation requirements buried in specifications
The warranty document may not prominently state ventilation requirements, but the installation specs (a separate document) will. Not meeting those specs voids the warranty.
"Reasonable and customary" reimbursement
This language allows the manufacturer to set reimbursement rates below actual market prices. You may get $60/sq for shingles that now cost $110/sq.
No consequential damages
If a defective shingle causes a leak that destroys your ceiling, hardwood floors, and drywall, the warranty covers the shingle only -- not the $20,000 in interior damage.
Registration deadlines (60 days)
Miss the registration window and your enhanced warranty reverts to the basic material-only tier. Ask your contractor to handle registration and get confirmation.
Class action waivers
Some warranties require individual arbitration and prevent you from joining class action lawsuits for widespread product defects.
How to File a Warranty Claim
Document Everything
Take extensive photos of the damage from multiple angles. Note the date you first observed the issue. Save any related correspondence and your original installation documents.
Contact the Manufacturer Directly
For material warranty claims, contact the manufacturer (GAF, OC, CertainTeed) directly -- not your contractor. For workmanship warranty claims, contact the contractor first, or the manufacturer if it is a manufacturer-backed workmanship warranty.
Schedule the Inspection
The manufacturer will send an inspector at no charge. Be present during the inspection to point out all issues. The inspector works for the manufacturer so they are not on your side -- document everything independently.
Wait for Determination (2-6 Weeks)
The manufacturer will issue a written determination. If approved, they will specify the reimbursement amount and terms. If denied, you will receive the reason in writing.
If Denied: Your Options
Appeal the decision in writing with additional documentation. File a complaint with your state Attorney General's office (consumer protection division). Pursue small claims court if the amount is within your state's limit (typically $5,000-$10,000).
Warranty Transferability
Planning to sell your home? A transferable warranty adds resale value. Here is what each brand allows.
| Brand | Transfers Allowed | Deadline | Fee | Coverage After Transfer |
|---|---|---|---|---|
| GAF | 1 time | Within 60 days of sale | ~$50 | May reduce to non-prorated period |
| Owens Corning | 1 time | Within 60 days of sale | ~$75 | May reduce coverage terms |
| CertainTeed | 1 time | Within 60 days of sale | $100-$150 | May reduce to standard tier |
Selling tip: A transferable enhanced warranty (like GAF Golden Pledge or OC Platinum) with 10+ years remaining is a legitimate selling point. Include the warranty documentation in your listing materials and disclose it to potential buyers.

Frequently Asked Questions
What does a roofing warranty actually cover?
It depends on the warranty type. Manufacturer material warranties cover defects in the shingle itself (curling, cracking, premature granule loss) but typically only pay for replacement material, not labor. Manufacturer system warranties (like GAF Golden Pledge or OC Platinum Protection) cover both material and labor but require a certified installer and full system of accessories. Contractor workmanship warranties cover installation errors like improper nailing or flashing failures.
What is a prorated roofing warranty and how does it affect my payout?
A prorated warranty reduces coverage over time. For example, at year 20 of a 30-year warranty, the manufacturer might only cover about 50% of the material cost. On a $12,000 material defect, you would receive roughly $6,000 for materials while paying $6,000 out of pocket for materials plus $8,000-$15,000 for labor. Non-prorated warranties (like CertainTeed SureStart for the first 10 years) cover the full material cost regardless of age.
What voids a roofing warranty?
The most common warranty voiders are: high nailing (nails placed too high on the shingle, which is the number one cause), inadequate ventilation, unauthorized repairs by non-certified contractors, pressure washing, painting shingles, mixing ventilation types (e.g., ridge vent plus powered fans), and failing to register the warranty within 60 days of installation.
Can I transfer my roofing warranty when I sell my house?
Yes, all three major brands (GAF, Owens Corning, and CertainTeed) allow one warranty transfer to a new homeowner. The transfer must typically be completed within 60 days of the home sale and requires a fee of $50-$150. Note that coverage may be reduced after transfer, so check the specific terms.
What does "lifetime" mean on a roofing warranty?
A "lifetime" roofing warranty does not mean the rest of your life. In the roofing industry, lifetime typically means 40-50 years, and coverage is usually prorated after the first 10-15 years. Always read the fine print to find the actual coverage period and proration schedule.
How do I file a roofing warranty claim?
To file a claim: 1) Document the issue thoroughly with photos and dates, 2) Contact the manufacturer directly (not your contractor for material warranties), 3) Schedule the free manufacturer inspection, 4) Wait for the determination (typically 2-6 weeks). If denied, you can appeal the decision, contact your state Attorney General's office, or pursue small claims court.
Is a manufacturer system warranty worth the extra cost?
For most homeowners, yes. System warranties from certified installers (like GAF Silver Pledge or OC Platinum Protection) add $500-$2,000 to the project cost but provide 10-25 years of workmanship coverage backed by the manufacturer, not just the contractor. This protects you even if the contractor goes out of business. Given that only 5-15% of warranty claims result in a payout and installation issues are the top reason for denial, having workmanship coverage is valuable.
What percentage of roofing warranty claims actually get paid?
Industry estimates suggest only 5-15% of roofing warranty claims result in a payout. The top reason for denial is installation-related issues, which manufacturer material warranties do not cover. This is why choosing a certified installer who provides both manufacturer-backed workmanship and material coverage significantly improves your chances of a successful claim.
