Class 4 shinglesin El Paso
Class 4 is the top impact rating for asphalt shingles, but it isn't a hail guarantee, and in Texas it only pays off if your own insurer gives a credit for it. Ask your agent for a quote with and without it.
What Class 4actually means
A Class 4 shingle passed the top level of a lab test called UL 2218, which drops steel balls onto the shingle.4 One outside explainer puts the Class 4 ball at 2 inches, dropped from 20 feet.6
The test is pass or fail on cracking. A tear, fracture, or crack on the back of the shingle fails it, while dents and crushed granules on top alone do not.6 A second test, FM 4473, fires frozen ice balls instead.6
IKO sells Class 4 in its Nordic line. Its Cambridge and Dynasty lines are Class 3, and IKO says Nordic is available only in select markets.2
Class 4 is nothail-proof
IKO says so on its own Nordic page. The rating exists so owners can seek an insurance reduction, it isn't a guarantee against hail, and hail damage isn't covered under the limited warranty.2
Outside testers raise the same doubt. Haag Research and Testing tested five impact-resistant designs from four makers and found the reinforcements ruptured at every class. Some shingles looked like passes only because backing hid the cracks.4
The Insurance Institute for Business & Home Safety (IBHS) rates shingles with real hailstones. It found none of the products Excellent in 2025, and it doesn't recommend Marginal or Poor ones where hail falls.5
Short version. Class 4 is a test result and an insurance label. It isn't a promise that hail won't damage the roof.
Texas creditsvary by insurer
The Texas Department of Insurance (TDI) says a Class 4 roof covering would receive the highest premium credit. It also says the amount for each class is set by each insurance company.1
Each insurer also decides which test results it accepts, how the roofing is labeled for proof, and what paperwork you send.1 TDI publishes no percentage, so any figure you see online came from a vendor or a forum.
Some policies tie the credit to a cosmetic-damage exclusion. TDI's 1998 bulletin created an optional endorsement that excludes cosmetic hail damage on policies receiving the credit.7 Ask your agent whether yours does.
TDI also notes that new roofs often get a better rate than older ones, and that wind and hail deductibles are often higher than for other damage.8 Lifetime doesn't waive or cover deductibles. To see how we document damage for a claim, read about insurance claim documentation.
What to askyour agent
- What credit do you give for a Class 4 roof, in dollars per year on my policy?
- Which test label or paperwork do you accept?
- Does the credit come with a cosmetic-damage exclusion?
- What would the wind and hail deductible be on the new roof?
Take the yearly credit and compare it with what the Class 4 line costs over a Class 3 line. Lifetime Roofing of El Paso gives a free written estimate within 48 hours of the inspection, so you can price both.
Is it worth itin El Paso?
It depends on your insurer's credit, because El Paso's wind losses run well under the Texas average. TDI's county file shows $175 paid per policy in 2025 for wind, against $1,010 across Texas.3
El Paso stayed below the statewide figure in every year from 2019 to 2025, but it wasn't zero. Its per-policy figure reached $437 in 2023.3 TDI doesn't define what its wind column covers, so treat the figures as a comparison, not a hail count.
Sun wears out a shingle roof here as much as hail does. InterNACHI notes that hot climates drastically reduce asphalt shingle life.9 A rating built around hail does nothing for that.
Rule of thumb. If your insurer offers a real credit for Class 4 and you can have the shingle, price it. If it offers nothing, Class 3 is the simpler choice.

Questions people askabout Class 4 shingles
Will Class 4 shingles lower my insurance in Texas?
Maybe. Texas says a Class 4 roof gets the highest credit, but each insurer sets the amount and the paperwork. Lifetime Roofing of El Paso suggests asking your agent for a quote with and without Class 4 shingles before you choose.
Is a Class 4 shingle hail-proof?
No. IKO's own footnote says the rating is not a guarantee against hail, and hail damage isn't covered under its limited warranty. Lifetime Roofing of El Paso installs IKO shingles, and we tell customers the same thing.
What is the difference between Class 3 and Class 4 shingles?
Class 4 passed a heavier test. Among IKO lines, Cambridge and Dynasty are Class 3 and Nordic is Class 4. In practice, the difference is the credit your insurer gives.
Does IKO's warranty cover hail damage?
No. IKO's Nordic page states that damage from hail is not covered under the limited warranty. Lifetime Roofing of El Paso adds a lifetime transferable warranty on our installation work, which covers workmanship, not hail.
Are Class 4 shingles worth it in El Paso?
Only with a real credit. El Paso's 2025 wind losses were $175 per policy against $1,010 across Texas, so the savings case depends on your own quote.
