Frisco homeowners comparing shingle quotes often see IKO’s two Performance shingles: Dynasty and Nordic. On paper they’re nearly twins. The one number that separates them is the one that matters most when North Texas hail hits: impact rating.

I’m Blake Snow, and I’ve been roofing for 30 years. We install IKO to the manufacturer’s specs. Here’s how the two compare, using IKO’s own product pages.

IKO notes all values are approximate and that extended warranties through an IKO ROOFPRO contractor can carry different application requirements. We confirm the current specs, colors and Frisco availability before you sign.

What “True Square Advantage” means on your roof

Both shingles are bigger than a typical architectural shingle: about 40 ⅞ inches long with a 5 ⅞-inch exposure, versus the 39 ⅜-inch, 5 ⅝-inch metric size many brands use. More exposure means fewer courses up the roof and a bolder look. It also means IKO shingles don’t course in with other brands. If you ever need a repair, it should be IKO on IKO.

Class 3 or Class 4 in Frisco?

  • Dynasty (Class 3) survived 1.75-inch steel balls in the lab. It meets our rule: every shingle roof we install is Class 3 or better under UL 2218. It’s a solid choice if your insurer gives little or no credit for Class 4.
  • Nordic (Class 4) survived 2-inch steel balls, and its polymer-modified asphalt stays more flexible. It’s the better pick if your insurer gives a meaningful Class 4 credit or you’ve already replaced a roof after hail once.

Neither is hail-proof. IKO is clear that the impact rating is there to help you qualify for a premium reduction, and that hail damage is not covered under its Limited Warranty. Hail is an insurance matter, not a warranty claim. See our Texas impact-resistant roof insurance guide and best Class 4 shingles for Texas.

What the warranty does cover

“Lifetime” in IKO’s wording runs as long as the original owner owns the home. Iron Clad Protection is IKO’s early-years coverage period, 15 years on both. Wind coverage is 130 mph on both. Algae coverage is 10 years and applies to blue-green algae. Read the full IKO Limited Warranty for the terms, and we’ll put the manufacturer and workmanship warranties in writing on your quote.

What we do on a Frisco IKO roof

  • Full tear-off to the deck, with deck repairs as needed
  • IKO starter and hip and ridge shingles, plus new drip edge
  • New flashings at walls, chimneys and valleys
  • A free digital photo report and a workmanship warranty from 10 years up to lifetime, depending on the job

See our IKO Dynasty and Nordic page for more.

After a storm

Get the roof inspected and documented before anyone patches it. In Texas you generally have 1 year from the date of loss to file a claim, but check your policy. Our storm damage page explains the process.

Frequently asked questions

What's the difference between IKO Dynasty and Nordic?

Per IKO's specs, they're the same size (40 7/8 by 13 3/4 inches) with the same 5 7/8-inch exposure, 60 shingles per square, 130 mph wind warranty and 15 years of Iron Clad Protection. The big difference is impact: Dynasty is rated Class 3 and Nordic is rated Class 4 under FM 4473 / UL 2218. Nordic uses polymer-modified asphalt for flexibility.

Is IKO Nordic available in Frisco?

IKO says Nordic is sold only in select markets and has fewer colors than Dynasty. We check current availability and colors for your ZIP before we quote it.

Does IKO's warranty cover hail?

No. IKO states that the impact rating is for insurance premium purposes and that hail damage is not covered under its Limited Warranty. Hail damage is an insurance matter.

Will Nordic lower my insurance premium?

It might. The Texas Department of Insurance says insurers may give a premium credit for UL 2218 roofs, the amount varies by company, and Class 4 generally earns the largest credit. Ask your insurer before you choose. We provide TDI Form PC068 when we install a qualifying roof.

Can I patch a Nordic roof with Dynasty?

They're the same size, so the courses line up, but the color palettes differ and you'd be mixing impact ratings on one roof. We repair with the same product and color whenever we can find it.

Hail hit my Frisco roof. What now?

Get it inspected and photographed before repairs. In Texas you generally have 1 year from the date of loss to file an insurance claim, but check your policy.
