GAF Timberline vs.
TAMKO Storm Series.

When you call me for a roof, one of the first real decisions we make together is the shingle. I install two lanes, and they're built for two different priorities. GAF Timberline is my default — the classic, proven lineup most homeowners go with. The TAMKO Storm Series is the hail-and-impact lane I reach for when storms are the thing you're actually worried about.

This is the plain-English version of the conversation I have on the driveway. No sales pitch — just how I'd help you pick.

The GAF Lane: Classic, Proven, My Default.

I'm a GAF Certified™ Contractor, and GAF Timberline is what goes on most of my roofs. The lineup climbs from value to premium:

• Timberline NS (Natural Shadow) — the entry architectural shingle. A real dimensional roof at the honest baseline price. Great for rentals, a house you'll sell in a few years, or a budget that needs to stay tight.
• Timberline HDZ — the most-installed shingle in America, and where most of my customers land. LayerLock install, the WindProven no-max-speed wind warranty, StainGuard Plus algae protection, and the broadest color palette.
• Timberline UHDZ — GAF's premium, with a UL 2218 Class 4 impact rating that can earn you an insurance discount. The hail pick within the GAF lane.

Pick the GAF lane if you want the classic, widely-recognized lineup with the System Plus warranty I can register as a certified contractor. It's my go-to, and there's a reason: it's proven, the colors are everywhere, and the install crew handles it the same way every time. Full GAF Timberline lineup, every color and spec, here.

The TAMKO Lane: Built for Hail Country.

The TAMKO Storm Series is the lane I built into NBD for homeowners whose number-one concern is hail and high wind. It also climbs from value to premium, but the top end is all about impact:

• Heritage — the value floor. A true architectural roof at the best price in the lineup, with a limited-lifetime warranty. My straight-up value pick on the TAMKO side.
• Titan XT — step up to impact. UL 2218 Class 3 impact, a 160 mph wind rating with the TAMKO system, and an award-winning build. Real protection without the top-tier price.
• StormFighter Flex — full UL 2218 Class 4 impact, 160 mph wind, and a cold-weather install window that fits our shoulder seasons. It was voted #1 Product of the Year in a 40,000-person survey.
• HailGuard — the top of the lineup, and the headline: Class 4, tested beyond, and the first asphalt shingle to carry a written hail warranty.

Pick the TAMKO lane if hail is the thing that keeps you up at night — you've already filed a claim, or your block gets hammered every spring. Full TAMKO Storm Series here.

The Real Decision: Classic vs. Hail-Priority.

Strip away the brand names and it's actually a simple call:

If you want the proven, classic roof and the GAF warranty, you're in the GAF lane. If your top priority is surviving hail — and especially if you want a written hail warranty — you're in the TAMKO Storm Series.

Both lanes have a Class 4 option (GAF UHDZ and TAMKO StormFighter Flex / HailGuard), so you can get top-tier impact protection either way. The tiebreaker at the very top is HailGuard's written hail warranty, which GAF doesn't match. Everywhere below that, it's about which lineup and warranty system you'd rather stand behind.

What Stays the Same Either Way.

Here's the part I care about most: the shingle is your choice, but the way I build and back the roof doesn't change. Whichever lane you pick:

• The Pledge rides on every roof — you call me about anything I worked on, I come look, free, forever.
• The NBD Build components — LumaNail fasteners, the GAF Pivot Boot, Roofivent ventilation — are available on any shingle. In fact, I run GAF / Roofivent vents and pipe boots on TAMKO roofs too, because those are the parts I've watched outlast everything else.
• I'm on your roof with the crew — tear-off, decking check, the full system, signed off before I leave.

One spec note worth knowing: a TAMKO storm warranty (the 160 mph wind rating, or the HailGuard hail warranty) requires TAMKO's own underlayment, starter, and hip & ridge — so a TAMKO storm roof is built with TAMKO accessories where the warranty calls for them. I build it to spec so the coverage actually sticks.

So Which One Do I Recommend?

Honestly? For most homeowners, GAF Timberline HDZ is still the sensible default — it's proven, it looks great on every street in Cincinnati, and the warranty is rock-solid. I'd put it on my own house without thinking twice.

But if you're in a hail-prone pocket, if you've already eaten a deductible on a hail claim, or if the idea of a written hail warranty genuinely matters to you, the TAMKO Storm Series — Titan XT, StormFighter Flex, or HailGuard — is exactly why I added that lane. That's not a sales move; it's me wanting the right roof on your specific house.

The good news is you don't have to figure this out alone. I'll walk your roof, look at your exposure, talk through your insurance situation, and give you straight numbers for both lanes. Then you pick.

Quick FAQ.

Is TAMKO as good as GAF?

They're both major, established manufacturers with strong shingles — this isn't a name-brand-vs-off-brand question. GAF Timberline is my proven default; the TAMKO Storm Series is purpose-built for impact and hail. The "better" one is the one that fits your priority. For classic and broadly proven, GAF. For hail-tough with a written hail warranty at the top, TAMKO.

Can I get a Class 4 impact roof in either lane?

Yes. GAF Timberline UHDZ is Class 4, and on the TAMKO side both StormFighter Flex and HailGuard are Class 4 (HailGuard tested beyond). Any of them can qualify you for an insurance premium discount with the right documentation.

Do I lose the GAF warranty if I go TAMKO?

You get the TAMKO warranty system instead — the manufacturer warranty follows the shingle you install. Either way you still get the NBD Pledge on my workmanship, which is independent of the manufacturer and applies forever.

Which is more expensive?

It depends entirely on the rung you pick, not the brand — a value shingle in either lane costs less than a premium one in the other. I'll give you real per-square numbers for both at your free estimate so you're comparing actual prices, not guesses.
