When AMP Restoration & Roofing replaces your roof with a GAF system, you're getting more than shingles. A GAF Lifetime Roofing System is a coordinated set of components — shingles, leak barriers, underlayment, ventilation, and starter strips — engineered to work together and backed by one of the strongest warranties in the roofing industry.
Here's what every Missouri and Indiana homeowner should know before choosing their next roof.
What Is a GAF Lifetime Roofing System?
A GAF Lifetime Roofing System requires installing GAF Lifetime Shingles (like Timberline HDZ) along with at least three qualifying GAF accessory products. When installed by a GAF Master Elite contractor like AMP, this unlocks the GAF System Plus Warranty — covering shingles, accessories, and installation labor.
The key components include:
- Timberline Lifetime Shingles — the #1-selling shingle in North America, with LayerLock technology and 130 MPH wind resistance
- WeatherWatch® Leak Barrier — self-sealing ice and water protection at eaves, valleys, and penetrations
- Deck Armor™ Premium Breathable Underlayment — moisture protection between the deck and shingles
- Pro-Start® Starter Strip Shingles — engineered to prevent wind-driven rain intrusion at eaves
- Cobra® Ridge Vent — balanced attic ventilation that extends the life of the full system
System Plus Warranty: What's Actually Covered
The GAF System Plus Warranty is the highest coverage tier available — and it's only accessible through a GAF Master Elite contractor. Here's what it includes:
| Coverage | Term | Details |
|---|---|---|
| Shingles (manufacturing defects) | Lifetime | Full replacement including tear-off and installation |
| Non-prorated coverage | 50 years | Full replacement value, not depreciated |
| Wind resistance | Lifetime | Up to 130 MPH with proper installation |
| Installation workmanship | 10 years | AMP's labor warranty on System Plus jobs |
| Accessory products | System term | Leak barriers, underlayment, and vents included |
Important: The System Plus Warranty is only available through GAF Master Elite contractors. AMP is one of fewer than 3% of roofers in the country who qualify for this designation.
Why Master Elite Status Matters to You
GAF Master Elite certification requires ongoing training, licensing verification, insurance compliance, and quality auditing. It's not a one-time achievement — contractors must maintain standards year over year.
For homeowners, this means:
- Access to the highest-tier GAF warranty (System Plus)
- Confidence that installation meets manufacturer specifications
- Priority support from GAF if warranty issues arise
- A contractor with verifiable credentials and a track record
AMP also holds the 2023 GAF President's Club Award — recognition given only to top-performing Master Elite contractors each year. Learn more about the AMP Guarantee.

Is a GAF System Worth the Upgrade?
For most Missouri homeowners, yes. The System Plus Warranty's 50-year non-prorated coverage means that if your shingles fail in year 20, you receive full replacement value — not a depreciated payout. Combined with AMP's storm damage expertise and insurance claim support, a GAF Lifetime System is one of the best long-term investments you can make in your home.
