Class 4 shingles are the most impact-resistant asphalt shingles available, designed to stand up to extreme weather like hail, high winds, and heavy storms. If you’re looking for a longer-lasting, storm-ready roofing solution, Class 4 shingles might be the upgrade your home needs.
In this guide, we’ll cover:
- What makes a shingle “Class 4” rated
- The top benefits of installing impact-resistant shingles
- How much Class 4 shingles cost (and whether it’s worth it)
Let’s explore how these shingles work and whether they’re the right choice for your next roofing project.
🤔 What Makes a Shingle Class 4?
Class 4 shingles receive the highest impact rating under the UL 2218 standard—a nationally recognized test that measures how well roofing materials withstand hail and debris strikes.
The UL 2218 Impact Test
The UL 2218 test drops a steel ball from varying heights onto the surface of the shingle to simulate hail impact.
- Class 1 to Class 4: Roofing products are rated from Class 1 (lowest) to Class 4 (highest).
- Steel ball testing: A 2-inch steel ball is dropped from 20 feet onto the same spot twice.
- Pass criteria: To qualify as Class 4, the shingle must show no signs of cracking, rupturing, or breaking on the front or back.
Why This Rating Matters
A Class 4 rating means your roof is more likely to survive a major hailstorm without needing repairs or a full replacement. Many insurance companies also offer premium discounts for homes with Class 4 shingles.
✅ Benefits of Class 4 Shingles
These shingles are built for durability—but that’s not the only reason they’re growing in popularity across storm-prone regions.
Enhanced Storm Protection
- Hail resistance: Class 4 shingles can handle large hail without splitting or denting.
- Wind performance: Many Class 4 shingles are rated to withstand winds of up to 130 mph.
- Better granule retention: Impact-resistant shingles hold their surface coating better over time, extending the life of your roof.
Insurance Premium Discounts
- Cost savings: Some insurers offer discounts up to 20% for homeowners who install Class 4 impact-resistant shingles.
- Policy perks: Installing these shingles can also help you avoid costly deductibles for cosmetic damage, depending on your coverage.
Long-Term Value
- Extended lifespan: Class 4 shingles often last longer than standard asphalt options due to their superior materials and construction.
- Resale appeal: A roof with high-impact resistance adds value and peace of mind for future buyers.
💵 Average Cost of Class 4 Shingles
You can expect to pay more upfront for a Class 4 roof, but many homeowners find the long-term savings and protection worth the investment.
Material and Installation Costs
The total cost of a Class 4 shingle roof varies based on brand, location, and complexity of the job.
- Per square foot: Materials range from $1.25 to $2.50 per square foot, depending on the manufacturer.
- Installed cost: Including labor, most homeowners spend between $7,000 and $14,000 for a full roof installation with Class 4 shingles.
- Comparison: That’s about 10% to 25% more than standard asphalt shingles.
Factors That Influence Cost
- Roof size and pitch: Larger or steeper roofs require more labor and materials.
- Tear-off costs: If your old roof needs to be removed, that adds to the final bill.
- Underlayment and accessories: Upgrading to synthetic underlayment or new flashing may raise the price.
