Class 4 Impact-Resistant Shingles in Nebraska: Worth It, and Will Insurance Give You a Discount?

If you have priced a roof in Omaha or Lincoln lately, somebody has offered you a Class 4 shingle. The pitch is that it stands up to hail and your insurance company might give you a break for it. Both of those things are true, with some fine print. Here is the plain version.

What Class 4 actually means

The rating comes from a test called UL 2218. A steel ball is dropped on the shingle from a set height, and the shingle is checked for cracks on the back. Class 4 is the top rating: a two-inch steel ball dropped from twenty feet, twice in the same spot, with no cracking. That is a hard hit. It is roughly the energy of a large hailstone.

A standard architectural shingle is not rated at all. That does not mean it fails every storm, but it means nobody tested it and the manufacturer will not stand behind it against hail.

Which shingles qualify

The two lines we install most are both available in Class 4 versions. CertainTeed Landmark ClimateFlex is a Class 4 shingle built with a polymer-modified asphalt that stays flexible instead of shattering. Owens Corning Duration FLEX does the same thing with Owens Corning's SBS-modified formula. Both look like a normal architectural shingle from the street. The difference is what happens when a hailstone lands on them.

What it costs

Class 4 shingles cost more per square than the standard version of the same line. On a typical Omaha roof the difference is a meaningful line item, not a rounding error, but it is a fraction of the total job because the labor, tear-off, underlayment and flashing are the same either way. We quote both versions side by side on every roof estimate so you can see the actual number for your house instead of a percentage.

Will insurance give you a discount?

Often, yes, and this is where it gets interesting. Many carriers writing homeowner policies in Nebraska offer a premium discount for a Class 4 roof, because it lowers the odds they pay for a hail claim. The size of the discount varies by company and by policy, and some carriers require a certificate from the installer showing the product and install date. We provide that.

The honest caveat: a few carriers pair the discount with a cosmetic damage exclusion, meaning they will not pay to replace a Class 4 roof that got dented but did not fail. Read that part of the endorsement before you sign it. For most people it is still a good trade, because a Class 4 roof is far less likely to need the claim in the first place.

Call your agent with the product name and ask two questions: what is the discount, and is there a cosmetic exclusion. Two minutes on the phone, and you will know.

Is it worth it?

If you plan to be in the house for more than a few years, we think so. Eastern Nebraska sees hail most summers. A standard roof in this climate rarely makes the number on the warranty, and a lot of them get replaced after a storm well before they wore out. A Class 4 roof changes those odds, and the insurance discount pays back part of the upgrade every year you own the house.

If you are selling in the next year or two, the math is closer, and we will tell you that too.

One thing Class 4 does not fix

Installation. A Class 4 shingle nailed wrong, on a roof with no ice-and-water shield and bad ventilation, is still a bad roof. The rating is about the shingle. The system is about the crew. Ask any roofer, us included, to show you photos of the underlayment and flashing on a recent job before you decide.
