Class 3 vs Class 4 Shingles: What’s the Difference?

If you’ve been researching impact-resistant shingles, you’ve probably seen the terms Class 3 and Class 4.

Both are designed to perform better in hail and severe weather than standard architectural shingles — but the difference matters, especially in Arkansas, where hail and high winds are common.

This guide clearly breaks down the differences so you can make the best decision for your home.

What Does “Impact Class” Mean?

Impact ratings are based on UL 2218 testing. In this test, steel balls are dropped from specific heights onto the shingle surface to simulate hail impact. The shingle is then inspected for cracking or failure.

The higher the class number, the greater the impact resistance.

Class 1 – Basic impact resistance
Class 2 – Moderate impact resistance
Class 3 – Enhanced hail resistance
Class 4 – Highest impact resistance available in asphalt shingles

For most homeowners, the real decision comes down to Class 3 vs Class 4.

Class 3 Shingles

Class 3 shingles are impact-resistant architectural shingles built to handle moderate hail and debris impact.

Benefits of Class 3 Shingles:

Stronger than standard architectural shingles
More budget-friendly than Class 4
May qualify for insurance discounts (carrier dependent)
Great balance of cost and durability

A common example is Atlas Pinnacle Pristine, which offers strong wind ratings, Scotchgard™ protection to help prevent algae streaking, and dependable impact resistance.

For many Arkansas homeowners, Class 3 provides reliable storm protection without a major jump in price.

Class 4 Shingles

Class 4 shingles carry the highest impact rating available for asphalt roofing materials.

They are tested using a 2-inch steel ball dropped from 20 feet and must show no cracking on the back of the shingle.

Benefits of Class 4 Shingles:

Maximum hail resistance
Often qualify for larger insurance discounts
Reduced likelihood of future hail claims
Designed for severe weather regions

One of the most popular Class 4 options we install is Atlas Pinnacle Impact (Pinnacle IR). It combines high impact resistance with strong wind ratings and durability, making it a practical upgrade for Arkansas homes that see recurring hail events.

Which Should You Choose?

In Arkansas, many homeowners are moving toward Class 4 shingles after experiencing repeated hail damage. In some cases, the insurance discounts can help offset the upgrade cost over time.

However, Class 3 remains a very solid option for homeowners looking to improve durability while staying within a tighter budget.

The right choice depends on:

Your storm exposure
Your insurance carrier’s discount program
How long you plan to stay in the home
Your overall roofing budget

Final Thoughts

Both Class 3 and Class 4 shingles are significant upgrades over standard architectural shingles.

If you’re replacing your roof after a storm or planning before hail season, understanding the difference can help you make a smarter long-term investment.
