Is Class 4 Impact Resistant Roofing Worth It in Illinois?

If You Live in Illinois, Hail Is Not a “Maybe” — It’s a Matter of When

Rockford and Northern Illinois homeowners are no strangers to severe weather. Hailstorms, high winds, and fast-moving summer systems can cause significant roof damage — sometimes in just minutes.

After a storm, many homeowners hear a new term from contractors and insurance adjusters:

“Class 4 impact resistant roofing.”

But what does that actually mean?
Is it worth the upgrade?
And does it make sense for your Rockford home?

At Honeybee Roofing, we believe homeowners deserve clarity — not sales pressure. Let’s break it down.

What Does “Class 4 Impact Resistant” Actually Mean?

Class 4 is the highest impact resistance rating a roofing product can receive under the UL 2218 impact test standard.

Here’s how the test works:

• A 2-inch steel ball is dropped from 20 feet
• The impact simulates hail striking the roof
• The material is inspected for cracking or rupture

To qualify as Class 4, the roofing product must withstand multiple impacts without cracking.

This does not mean the roof won’t show cosmetic marks — but it does mean the structural integrity remains intact.

Why Class 4 Matters in Rockford, Illinois

Rockford experiences:

• Frequent hail-producing storms
• High straight-line winds
• Freeze–thaw cycles that worsen minor damage

Traditional asphalt shingles (often Class 1 or 2) can bruise or crack under hail impact. Even minor cracking allows moisture intrusion over time.

Class 4 roofing systems are engineered to significantly reduce that risk.

That’s why many homeowners exploring metal roofing in Rockford begin looking specifically at impact-resistant options.

Can Metal Roofing Qualify as Class 4?

Yes — many metal roofing systems qualify for Class 4 impact resistance.

In fact, properly installed standing seam metal roofing systems are among the most durable roofing options available in Illinois.

Because metal panels distribute impact energy differently than asphalt shingles, they often resist functional damage more effectively.

Does Class 4 Roofing Lower Insurance Premiums?

In some cases, yes.

Many insurance carriers in Illinois offer discounts for Class 4 impact resistant roofing because:

• It reduces claim frequency
• It lowers long-term risk exposure
• It performs better during hail events

However, discounts vary by carrier and policy. Some insurers may offer minimal savings — others may offer more meaningful reductions.

We always recommend homeowners verify directly with their insurance provider before making a decision based solely on premium savings.

Is Class 4 Worth the Upgrade Cost?

It depends on your goals.

Class 4 roofing is often worth it if:

• You’ve experienced hail damage before
• You plan to stay in your home long-term
• You want fewer storm-related repairs
• You value long-term durability over lowest upfront cost

For many Rockford homeowners, the decision isn’t just about insurance discounts — it’s about peace of mind.

Class 4 Asphalt Shingles vs Class 4 Metal Roofing

Impact Rating	Class 4	Class 4
Lifespan	20–30 years	40–70+ years
Maintenance	Moderate	Low
Storm Durability	Good	Excellent
Long-Term Value	Moderate	High

While both can carry a Class 4 rating, metal roofing often delivers superior long-term performance in Illinois conditions.
