Architectural Shingles
About GAF
GAF (General Aniline & Film) is North America’s largest residential roofing manufacturer, producing roofing materials at scale for over 130 years. They install on more US homes than any other brand and have built their reputation on consistent quality control and a strong contractor certification program.
Their Timberline architectural shingle line is the single most-installed architectural shingle in America. For most Warner Robins homes, GAF is the safest, most-supported, easiest-to-warranty option.
GAF Timberline Series
The Timberline series is GAF’s flagship architectural shingle line, with three tiers:
- Timberline HDZ — the standard. 130 mph wind rating, 30-year warranty, StainGuard Plus algae protection. Best value for most Middle Georgia homes.
- Timberline UHDZ — premium upgrade. Heavier shingle (240 lbs/square), more dimensional profile, lifetime warranty. Best look + longevity.
- Timberline AS II / Armor Shield II — Class 4 impact-rated. Recommended for homes in hail-prone areas like Byron and the I-75 corridor. May qualify for an insurance discount.
GAF Warranty
Standard GAF Timberline warranties cover the shingles for 30 years prorated against material defects. The wind warranty is 130 mph (subject to proper installation per GAF specs).
Every GAF roof we install carries GAF’s standard limited shingle warranty plus Ridgeback’s own 10-year workmanship warranty. If extended manufacturer coverage is your top priority, ask us about IKO — as an IKO ROOFPRO Craftsman Premier contractor, we can offer IKO’s Extended Iron Clad Protection limited warranty on qualifying installs.
Color Options
GAF Timberline HDZ comes in 30+ colors across architectural style families — from the traditional Charcoal and Weathered Wood to the modern Slate, Pewter Gray, and Hickory. They also offer Cool Roof colors (Reflector Series) that reflect more solar heat — useful for Georgia summers, though they reduce winter solar gain too.
On every install we bring physical color samples to your home and check them in your actual lighting conditions before final selection. The same color can look dramatically different in morning vs afternoon light.

Frequently Asked Questions
What is the difference between GAF Timberline HDZ and UHDZ?
HDZ is the standard architectural shingle — 30-year warranty, 130 mph wind rating, 215 lbs/square. UHDZ is the premium upgrade — heavier (240 lbs/square), more dimensional, with a lifetime warranty. UHDZ costs about 15-20% more but lasts longer and has more visual depth.
Is GAF a good brand for Warner Robins homes?
Yes — GAF is the most-installed architectural shingle brand in America for good reason. Their Timberline HDZ handles Middle Georgia heat and humidity well, the 130 mph wind rating meets local needs, and warranty support is reliable.
What warranty comes with a GAF roof from Ridgeback?
Every GAF roof we install carries GAF’s standard limited shingle warranty plus Ridgeback’s 10-year workmanship warranty. If you want extended manufacturer coverage, we recommend IKO: as an IKO ROOFPRO Craftsman Premier contractor, we can offer IKO’s Extended Iron Clad Protection limited warranty on qualifying installs.
Does GAF Timberline come with algae protection?
Yes. All Timberline HDZ shingles include StainGuard Plus, which uses copper granules to prevent the dark streaking caused by algae growth — common in humid Middle Georgia. The standard coverage is 25 years.
How long does a GAF roof last in Georgia?
Most GAF Timberline HDZ roofs last 25-30 years in Middle Georgia. Premium GAF lines (UHDZ, Armor Shield II) can push 35-40 years. Proper installation, ventilation, and routine maintenance are bigger factors than the shingle brand itself.
How much does a GAF roof cost in Warner Robins?
A GAF Timberline HDZ replacement typically runs $4.50-$6.50 per square foot installed in Warner Robins. For a 2,000 sqft home, expect $9,000-$13,000. Premium GAF lines (UHDZ or Class 4 impact) add 15-25%. Insurance-paid replacements have no out-of-pocket beyond your deductible.
