Understanding Shingle Impact Resistance Ratings

Published On: June 7, 2025

When it comes to protecting your home in Stephenville, TX, the quality and strength of your roofing system are critical. Between hailstorms, strong winds, and the occasional flying debris, your roof has to be tough—and that starts with the shingles. But not all shingles are built the same, and that’s where impact resistance ratings come into play.

At DT Roofing, we regularly help homeowners choose the right shingles based on local weather threats and performance expectations. One of the most important factors to consider when choosing roofing materials is their impact resistance rating. These ratings help determine how well your shingles will hold up against hail and other impacts, ultimately affecting your home’s durability, safety, and long-term repair costs.

What Are Impact Resistance Ratings?

Impact resistance ratings are standardized measurements used to evaluate how well a roofing material—usually asphalt shingles—can withstand impact from hail or flying debris. The most common scale used in the roofing industry is the UL 2218 classification, which was developed by Underwriters Laboratories. This test simulates the effect of hailstones by dropping steel balls of various sizes from specific heights onto a roofing sample.

Based on how well the shingle withstands the impact without cracking or splitting, it’s given a Class rating from 1 to 4, with Class 4 being the highest.

UL 2218 Impact Resistance Classes:

  • Class 1: Least resistant to impact

  • Class 2: Withstands 1.25-inch steel balls dropped from 12 feet

  • Class 3: Withstands 1.75-inch steel balls dropped from 17 feet

  • Class 4: Withstands 2-inch steel balls dropped from 20 feet

Class 4-rated shingles are often referred to as “impact-resistant” or “IR” shingles and are ideal for areas with frequent hail activity—making them an excellent choice for homeowners in Stephenville and surrounding regions.

Why Impact Resistance Matters in Texas

Texas is no stranger to hailstorms. The state consistently ranks among the top in the nation for hail-related insurance claims, with damage often running into thousands of dollars per roof. Choosing impact-resistant shingles significantly lowers your risk of expensive repairs following a storm. More importantly, it adds a layer of peace of mind, knowing that your roof has been engineered to withstand harsh conditions.

In Stephenville, where hailstorms can strike quickly and unpredictably, opting for Class 4 shingles means your roof is better equipped to endure the elements, and you’re less likely to deal with leaks, interior water damage, or sudden emergency repairs.

Insurance Benefits of Impact-Resistant Shingles

One of the often-overlooked advantages of installing high-impact shingles is the potential for insurance savings. Many insurance providers offer premium discounts for homes equipped with Class 4-rated roofing systems. This is because the roof is less likely to suffer damage during storms, reducing the likelihood of a claim.

Before upgrading, check with your insurer to see if your policy includes incentives or reduced deductibles for IR shingles. Keep in mind that not all Class 4 products are treated equally by every insurance company, so documentation and proper installation are key.

What to Look for in Impact-Resistant Shingles

Not all Class 4 shingles perform the same way. When evaluating your options, consider:

  • Brand Reputation: Look for manufacturers known for durability and quality. At DT Roofing, we install shingles from trusted names like Owens Corning, whose Duration® Storm and Duration® Flex lines are specifically engineered for superior impact resistance.

  • Warranty Coverage: Review the product’s warranty to ensure it covers hail and impact-related damage.

  • Material Composition: Some shingles use polymer-modified asphalt, which adds flexibility and resilience. This helps the shingle absorb impact energy rather than crack under pressure.

Our team can help you navigate these options and find the perfect fit for your roof, home design, and local climate.

Installation Matters: Even the Best Shingles Need Skilled Hands

No matter how strong the shingle is, poor installation can lead to premature failure. Proper fastening, correct alignment, and attention to flashing and ventilation are critical to ensuring the shingles perform as designed. Our in-house crews are trained to install impact-resistant systems to manufacturer specifications, maximizing your investment and ensuring eligibility for any warranties or insurance benefits.

Longevity and Resale Value

Beyond protection, impact-resistant shingles increase your home’s resale value. Potential buyers are more likely to be interested in a home that’s been updated with Class 4-rated roofing because it suggests fewer future expenses and enhanced security. It’s a smart long-term move, whether you plan to stay in your home for decades or sell in a few years.

Additionally, these shingles are often more aesthetically appealing. Available in a variety of styles and colors, they offer the flexibility to match your home’s architectural style without compromising on strength.

Don’t Wait Until After the Storm

One of the biggest mistakes homeowners make is waiting until after a storm to think about upgrading their roof. By that point, damage has likely occurred, and the urgency may force rushed decisions. Proactive planning not only gives you time to research and select the best materials—it may also help you take advantage of seasonal pricing and better contractor availability.

With the frequency and intensity of Texas storms, there’s no better time than now to assess your current roof and consider whether it’s up to the challenge. If you’re unsure about your existing roof’s impact resistance, our team can inspect it and provide honest recommendations tailored to your home’s needs.

Final Thoughts: Impact Resistance Is a Smart Investment

Choosing impact-resistant shingles for your Stephenville home isn’t just about storm protection—it’s about making a wise investment in your home’s longevity, safety, and value. From reducing insurance costs to preventing costly repairs and enhancing curb appeal, Class 4 shingles offer tangible benefits that extend far beyond their upfront cost.

If you’re considering a roof replacement or upgrade, let the professionals at DT Roofing help guide your decision. With our commitment to quality and deep knowledge of what works in Central Texas, we’ll ensure your roof is ready to stand strong—no matter what the skies bring.

We had an urgent leak in our house. We called and got scheduled right away within 24 hours someone was here at our house. Justin came out and did a thorough inspection, and found the issue. He helped us out so so much and we are beyond happy with the service provided. Not to mention within 10 mins of him leaving we got a detailed report with what he found and what was fixed. Highly recommend this company!!

I cannot say enough wonderful things about DT Roofing! They did a spectacular job from start to finish and truly went above and beyond what I expected. They thoroughly inspected everything, listened to every concern I had, and handled the entire process with absolute professionalism. They were able to get more approved than I ever expected, and Duane had an attention to detail that I haven't seen in a very long time. This is the Neiman Marcus of roofers! I am so grateful for the care and attention they put into making sure everything was done right. Mitch went above and beyond to finish up my project and was extremely patient waiting for my insurance final payment. He not only took care of everything to finalize our project, he also helped with things that weren’t even part of the job—simply because he saw that we were older and wanted to help. That kind of kindness and genuine care is rare, and it meant so much to us. Thank you so much, DT Roofing for taking such great care of us. You are truly an outstanding roofing company, and I would highly recommend you to anyone looking for honest, professional, and compassionate service!

Take time to listen to these guys! Storm came thru in April which tore up many roofs on my property. Got ahold of Brayden at Dt Roofing. He is kind, courteous and knowledgeable. He walked me thru the process, explaining each step. Their team worked with the insurance people and got all the correct follow up paperwork filed and completed. The work is quality work. Nothing shoddy about it. No corners cut. Even my energy bill is down. I would suggest anyone looking for competent and quality work to be done to give these guys a chance. And hopefully you'll be lucky enough to get Brayden. He's a Rock Star!!!
