Understanding Roofing Shingle Classes: What Do Class 3 and Class 4 Shingles Mean?
When shopping for a new roof, you may hear terms like Class 3, Class 4, or impact-resistant shingles—especially here in Kansas City, where hail, high winds, and severe storms are a regular part of life.
But what do these roofing classifications actually mean, and how do they impact your home?
Let’s break it down.
What Are Roofing Shingle Classes?
Roofing shingle “classes” refer to a shingle’s impact resistance, or how well it can withstand damage from hail and flying debris.
These ratings are determined through the UL 2218 impact resistance test, where steel balls are dropped from various heights onto roofing materials to simulate hail impact.
The higher the class rating, the greater the shingle’s resistance to impact damage.
Impact ratings range from:
- Class 1 — Basic impact resistance
- Class 2 — Moderate impact resistance
- Class 3 — Enhanced impact resistance
- Class 4 — Highest impact resistance available
What Is a Class 4 Shingle?
A Class 4 shingle offers the highest level of impact resistance currently available in asphalt roofing.
To earn this rating, a shingle must withstand repeated impact from a 2-inch steel ball dropped from 20 feet without cracking or tearing.
That makes Class 4 shingles especially appealing for homeowners in storm-prone areas like Kansas City.
Benefits of Class 4 shingles may include:
✔ Better resistance to hail damage
✔ Increased durability during severe weather
✔ Longer roof lifespan
✔ Potential insurance discounts (depending on carrier)
Do Class 4 Shingles Lower Insurance Premiums?
In some cases—yes.
Because Class 4 shingles offer the highest level of impact resistance, some insurance carriers may offer discounts or premium reductions for homeowners who install them.
Why? Simply put, roofs that are more resistant to hail and storm damage may be less likely to result in costly insurance claims.
That said, insurance discounts vary based on several factors, including:
- Your insurance provider
- Your policy coverage
- Your location and storm risk
- The specific roofing product installed
Not every carrier offers the same incentives, and not every Class 4 roof automatically qualifies for a discount.
That’s why it’s important to ask both your roofer and your insurance company what options are available.
At Becker Exteriors, we help homeowners understand not only their roofing choices, but also how those choices may impact long-term protection and potential insurance savings.
Why Kansas City Homeowners Often Consider Impact-Resistant Shingles
Kansas City weather can be tough on roofs.
Between spring hailstorms, summer wind events, and winter ice, many homeowners choose impact-resistant roofing for added peace of mind.
If your neighborhood has experienced repeated hail claims or severe storm damage, upgrading to a more impact-resistant shingle may be worth considering.
Why Owens Corning Shingles Stand Out
As an Owens Corning Preferred Contractor, Becker Exteriors installs roofing systems from one of the most trusted names in the industry.
Owens Corning offers premium architectural shingles designed to balance:
✔ Storm durability
✔ Strong manufacturer warranties
✔ Color and design options
✔ Long-term performance
Some Owens Corning product lines also offer enhanced impact resistance for homeowners looking for added storm protection.
Shingle Class Isn’t Everything—Installation Matters Too
Even the highest-rated shingle can fail if it’s installed incorrectly.
That’s why choosing the right contractor matters just as much as choosing the right materials.
Proper installation includes:
- Quality underlayment
- Proper flashing
- Manufacturer-approved installation methods
- Correct ventilation
In short: materials matter—but workmanship matters too.
Which Roof Is Right for Your Home?
The best roof depends on your home, budget, long-term goals—and in some cases, even your insurance coverage.
