Manufacturer Warranty vs Workmanship Warranty
Two warranties protect your roof — and they cover completely different things. Most homeowners don't realize their "lifetime warranty" only covers materials, not the labor to fix them. Here's what each actually protects:
Manufacturer Warranty
- Covers material defects (delamination, blistering)
- Covers premature granule loss
- Wind warranty up to 130 MPH (top tiers)
- Algae protection (top tiers)
- Does not cover installation errors
- Does not cover labor to replace defective shingles
- Often prorated after 10 years
Workmanship Warranty
- Covers installation errors (improper nailing, flashing)
- Covers leak-causing workmanship defects
- Covers labor and materials for repair
- Covers tear-off if reinstallation is required
- Does not cover manufacturing defects
- Duration varies wildly (2 years to lifetime)
- Only as good as the contractor's survival odds
Key Takeaway
Roughly 70% of roof failures trace back to installation errors, not material defects. A strong workmanship warranty is at least as important as the manufacturer warranty — and Proof Construction covers both at the highest tier available.
Prorated vs Non-Prorated Warranties
The single most important word in any roofing warranty is "prorated." A prorated warranty becomes less valuable every year — like a coupon that shrinks. Here's what it means in practice:
| Feature | Prorated Warranty | Non-Prorated Warranty Winner |
|---|---|---|
| Coverage Over Time | Decreases each year — after 10 years, you may only get 40% of material costs | 100% coverage for the entire warranty term — no decrease |
| Year 15 Claim Example | $8,000 roof → manufacturer covers ~$2,400 (30%), you pay $5,600 | $8,000 roof → manufacturer covers full material cost, you pay $0 |
| Labor Coverage | Usually excludes labor entirely after year 2 | Top-tier warranties include labor for the full term |
| Typical Availability | Standard with most contractor-grade shingles | Requires certified installer + premium shingle line |
| Transferability | Often reduced or voided when home is sold | Full transferability on top-tier warranties (Golden Pledge, 5-Star) |
Did You Know?
Many Tulsa roofing contractors install "lifetime" shingles but register them under the standard prorated warranty to save paperwork. Proof Construction registers every roof for the maximum non-prorated manufacturer warranty available. You shouldn't have to ask — it should be automatic.
GAF Golden Pledge vs Owens Corning Preferred vs CertainTeed 5-Star
These are the three premier roofing warranty programs available in Tulsa. All three require certified installer status — Proof Construction holds all three certifications.
| Feature | GAF Golden Pledge | Owens Corning Preferred | CertainTeed 5-Star |
|---|---|---|---|
| Material Coverage | 50-year non-prorated Best | Lifetime limited (prorated after 10 yr) | 50-year non-prorated Best |
| Workmanship Coverage | 25 years (GAF-backed) Best | 25 years (OC-backed) | 25 years (CertainTeed-backed) |
| Wind Warranty | 130 MPH | 130 MPH (with Duration Flex) Best | 110 MPH standard / 130 MPH upgrade |
| Tear-Off & Disposal | Included Best | Not included | Not included |
| Algae Protection | 15 years | 15 years | 15 years (StreakFighter) Best |
| Transferability | Full transfer to 1 subsequent owner | Transferable (reduced coverage) | Full transfer to 1 subsequent owner |
| Labor Included | Yes — full term Best | Yes — full term | Yes — full term |
| Required Inspections | GAF inspector signs off | No mandatory inspection Best | CertainTeed field rep inspects |
| Dispute Resolution | GAF mediates | OC mediates | CertainTeed mediates |
| Installer Requirements | GAF Master Elite certified | Owens Corning Preferred contractor | CertainTeed SELECT ShingleMaster |
| Proof Holds Certification | ✓ Yes | ✓ Yes | ✓ Yes |
Our Recommendation
GAF Golden Pledge offers the most complete coverage package — 50-year non-prorated material, 25-year workmanship, tear-off/disposal included, and full transferability. It's what we recommend for most Tulsa homeowners. Owens Corning Preferred is excellent if you want the 130 MPH wind rating with Duration Flex shingles. CertainTeed 5-Star matches Golden Pledge on material/warranty length and has superior algae protection. All three are outstanding — the real variable is the installer's workmanship, which is where Proof Construction's lifetime guarantee closes every gap.
Standard Contractor Warranty vs Proof Construction
This is the comparison that matters most. A manufacturer warranty is only as good as the contractor who installed the roof. Below is what you typically get from a standard Tulsa roofing contractor versus what Proof Construction provides on every job:
| Feature | Standard Tulsa Contractor | Proof Construction Winner |
|---|---|---|
| Workmanship Duration | 2–5 years (often prorated after 1 yr) | Lifetime — non-prorated |
| Material Warranty Tier | Basic prorated (contractor grade) | Golden Pledge / Preferred / 5-Star — non-prorated |
| Labor Coverage | Rarely beyond 2 years | Full labor included — lifetime |
| Tear-Off & Disposal | Not covered | Covered under Golden Pledge |
| Warranty Registration | Homeowner's responsibility (often forgotten) | We register for you, with confirmation |
| Manufacturer Certifications | 0–1 certifications | GAF Master Elite + OC Preferred + CertainTeed SELECT |
| Post-Installation Inspection | Rarely provided | Free annual drone inspection for 3 years |
| Claim Support | None — you deal with manufacturer alone | We handle all warranty claims end-to-end |
| Transferability | Voided on sale in most cases | Lifetime warranty transfers to next owner |
| Wind Warranty | 60–80 MPH typical | Up to 130 MPH |
| Company Longevity | ~50% of contractors out of business in 5 years | Established, insured, growing — here for the long haul |
Why Proof Construction's Warranty Holds Weight
The "Fine Print" Warranty Reality
A roofing warranty is only as strong as the company standing behind it. Roughly 50% of roofing contractors go out of business within 5 years — taking your warranty with them. Manufacturer-backed warranties (Golden Pledge, Preferred, 5-Star) solve this by having the manufacturer step in if the contractor disappears. Proof Construction layers our own lifetime workmanship guarantee on top of manufacturer backing — so you're protected either way.
- We've completed hundreds of roofs across the Tulsa metro — we're not going anywhere
- Every warranty registration is documented with confirmation from the manufacturer
- You get a physical warranty package with registration numbers, coverage terms, and claim instructions
- We offer a free annual drone inspection for the first 3 years post-installation to catch issues early
Common Warranty Questions
Manufacturer warranties cover defects in the roofing materials themselves — shingle delamination, premature granule loss, manufacturing flaws. Workmanship warranties cover errors in installation — improper nailing, flashing mistakes, leak-causing workmanship defects. Most roof failures stem from installation errors, making workmanship coverage equally critical. Proof Construction provides both: full manufacturer pass-through plus our own lifetime workmanship guarantee.
GAF Golden Pledge offers the most comprehensive coverage: 50-year non-prorated material, 25-year workmanship backed by GAF, plus tear-off and disposal coverage. Owens Corning Preferred Protection provides lifetime limited material with 25-year workmanship. CertainTeed 5-Star offers 50-year non-prorated material with 25-year workmanship. All three are excellent when installed by a certified contractor. Proof Construction is certified by all three, and we layer our own lifetime workmanship guarantee on top. We help you choose the best shingle + warranty combination for your specific home and budget.
Yes. Proof Construction provides a non-prorated lifetime workmanship warranty on every roof we install. If your roof leaks due to our installation and we're still in business, we fix it — no cost to you. This goes beyond the industry-standard 2–10 year contractor warranties. Additionally, we register every roof for the maximum non-prorated manufacturer warranty available. Combined, you're covered for both material defects and installation errors for decades.
Common warranty voiders include: improper ventilation (traps heat and moisture in the attic), installing new shingles over existing ones (no tear-off), pressure washing the roof, walking on the roof improperly, unapproved repairs by another contractor, and failure to register the warranty within the manufacturer's deadline (typically 60 days post-installation). Proof Construction handles all warranty registrations and provides a pre-installation ventilation assessment to ensure your warranty stays valid from day one.
It depends on the warranty tier. Top-tier warranties — GAF Golden Pledge and CertainTeed 5-Star — allow full transfer to one subsequent owner within a specified time window (usually 30–60 days after closing). Standard contractor-grade warranties typically terminate on sale. Proof Construction's lifetime workmanship warranty transfers to the next homeowner at no charge — we just need to be notified within 60 days of closing. A transferable warranty adds measurable resale value to your home.
Call Proof Construction at (918) 734-4444.

You don't need to figure out which warranty applies or navigate manufacturer claim portals on your own.
