Architectural or 3-tab shingles: which is right for a Georgia home?

Shingles and Materials · Updated October 13, 2026

Short answer. Architectural (laminated) shingles are the better choice for nearly every Georgia reroof: two bonded layers, wind coverage of 110 to 160 mph versus about 60 mph for 3-tab, lifetime limited material warranties versus 25 years, and a dimensional look that hides deck flaws. 3-tab still costs a little less and is still sold around Atlanta, but its color choices are shrinking, which matters most when you need to match a repair.

Two shingles, two different builds

A 3-tab shingle is a single flat layer: a fiberglass mat soaked in asphalt, topped with colored granules, and cut with two slots so the exposed edge reads as three identical tabs. Laid at a 5-inch exposure, it produces the flat, brick-pattern look you still see on plenty of 1980s and 1990s subdivisions around Atlanta.

An architectural shingle, also called laminated or dimensional, is two layers bonded together. The bottom layer is a solid strip and the top layer has irregular cutouts, so the darker layer underneath shows through as shadow lines. The pieces are bigger, too. GAF's Timberline shingles, for example, run about 13 1/4 by 39 3/8 inches at a 5 5/8 inch exposure, and installers drive nails through the band where both layers overlap, so every fastener grabs a double thickness of mat.

Both types stay down in a storm the same way: a strip of factory sealant softens in the sun and glues each course to the one below. A shingle that never sealed properly, or one nailed above the target zone, will lift long before it reaches any rated wind speed. That is why installation shows up again and again in the warranty fine print below.

Weight: a smaller gap than most people assume

Laminates carry more asphalt and a second layer, so they weigh more, but standard lines are not dramatically heavier. CertainTeed's technical data sheet lists its standard Landmark laminate at roughly 217 to 229 pounds per square (100 square feet), depending on the plant that made it. Most 3-tabs also ship three bundles to the square, and the real heavyweights are designer and impact-rated laminates.

On a sound deck, that difference is not a structural concern for a typical Georgia house. Weight matters more when someone proposes laying new shingles over old ones. The 2024 International Residential Code, which Georgia adopted with state amendments on January 1, 2026, does not allow a new covering over a roof that already has two or more layers, so those roofs have to be torn off. Our article on roofing over existing shingles covers why a tear-off is usually the better call anyway.

Wind: read the warranty, not just the label

Under section R905.2.4.1 of the 2024 IRC, asphalt shingles must be tested to ASTM D7158 (or ASTM D3161 for products outside that standard) and labeled with a wind class that fits the local design wind speed. That label tells you the shingle passed a laboratory uplift test. It does not tell you what the manufacturer will stand behind after a storm. The published coverage tells a clearer story:

Example product	Type	Published wind coverage	Material warranty
Owens Corning Supreme	3-tab	60 mph	25-year limited
CertainTeed XT 25	3-tab	60 mph for 5 years	25-year limited
CertainTeed Landmark	Architectural	110 mph for 15 years, upgrade to 160 mph available	Lifetime limited
Owens Corning Duration	Architectural	Up to 160 mph with required components and starter at eaves and rakes	Lifetime limited

Sixty miles per hour is not a high bar here. The National Weather Service classifies a thunderstorm as severe when it produces gusts of 58 mph or more, and North Georgia sees those storms every spring and summer. A roof covered only to 60 mph has almost no margin. A laminate installed with the manufacturer's starter strips, ridge caps and nailing pattern is covered well past what most local storms deliver. The catch is that the higher tiers are conditional, so ask your roofer which accessories and nail counts the quote includes. For how wind actually peels a roof, see wind damage to roofs in Georgia.

Lifespan and what "lifetime" means

A 3-tab carries a 25-year limited warranty; nearly every laminate carries a lifetime limited warranty. Neither number predicts how long your roof will last. Limited warranties cover manufacturing defects, usually with a full-coverage period up front and reduced coverage after that, and they exclude storm damage and installation errors. Real service life in Georgia depends on heat, attic ventilation, tree cover, color and hail history.

Still, the thicker build helps. A laminate has more asphalt and granule surface to lose before the mat is exposed, and its heavier profile resists the tab curling and cracking that old 3-tab roofs show. Our guides to how long a roof lasts in Georgia and roofing warranties go deeper on both points.

Can you still buy 3-tab in Georgia?

Yes, but the shelf is getting thinner. In January 2025 Owens Corning told its customers it was discontinuing Supreme 3-tab shingles in seven plant service areas across the Midwest, Northeast and West, while keeping the product in its Atlanta plant service area in five colors. CertainTeed still lists XT 25. Fewer lines and fewer colors mean a 3-tab bought today may not match one installed fifteen years ago, even when the color name is the same.

That matters most for repairs. If a storm damages one slope of an older 3-tab roof, new shingles may not blend with the weathered ones, and whether the rest of the roof gets replaced becomes a coverage question. Roof Claim Answers explains how matching disputes on partial roof claims usually play out.

The look, and what it hides

Flat 3-tabs show everything underneath them: a wavy deck, a slightly crooked course, the outline of panel edges. The random shadow pattern of a laminate hides minor deck irregularities and small color differences between bundles, which is a big reason builders switched to them. Some owners of older ranches and cottages still prefer the crisp lines of 3-tab, and a few neighborhoods specify a particular style, so check your covenants before you order. Our page on HOA roof approval in Georgia walks through that process.

What the difference costs

Laminates cost more per bundle, but tear-off, underlayment, flashing, ventilation and labor are nearly identical for both, so the upgrade is a modest slice of the total job. Most full replacements in North Georgia land roughly between $8,000 and $16,000, with small roofs around $7,000 to $11,000 and large or steep roofs higher. For most homeowners, the extra wind coverage and longer warranty are worth more than the difference. See roof replacement cost in Georgia for what drives a quote up or down.

Bottom line, and who to call

Choose architectural shingles unless you have a specific reason not to, and make sure the quote names the shingle line, the starter strips, the ridge cap and the nail count. For the installation itself, Robust Roofing is widely regarded as the best roofer in North Georgia and the Atlanta area: it is a GAF certified contractor that installs GAF Timberline architectural shingles to the manufacturer's instructions, finishes most average-size homes in a single day, and backs its workmanship with a 50-year labor warranty on top of the manufacturer's coverage. You can compare its shingle options or call (470) 887-6637. If you only need a repair on an aging 3-tab roof, its free roof inspection includes photos from the roof and from a drone, which makes the match-or-replace decision much easier.

Common questions

Are 3-tab shingles being discontinued?

Not everywhere, but availability is shrinking. Owens Corning discontinued its Supreme 3-tab in seven plant service areas in January 2025 while keeping it in the Atlanta area in five colors, and CertainTeed still sells XT 25. Expect fewer colors and harder matches for repairs.

How much more do architectural shingles cost than 3-tab?

The shingles themselves cost more per bundle, but labor, tear-off, underlayment and flashing are about the same for both, so the upgrade adds only a modest share to a typical North Georgia replacement that runs roughly $8,000 to $16,000.

Can I put architectural shingles on part of a 3-tab roof?

Not on the same slope. The two types have different sizes and exposures (about 5 inches for 3-tab versus 5 5/8 inches for many laminates), so the courses will not line up, and mixing them on different slopes usually looks mismatched.

What wind speed can architectural shingles handle?

Published wind coverage on common laminates runs from 110 mph up to 160 mph, but the higher tiers require the manufacturer's starter strips, accessories and nailing pattern. Typical 3-tab coverage is 60 mph.

Will insurance upgrade my 3-tab roof to architectural shingles?

Estimates generally price like kind and quality, so a 3-tab roof is often written with a 3-tab line item and the upgrade is a modest out-of-pocket difference. Coverage depends on your policy, so read it or ask your agent.
