Class 3 vs Class 4 Shingles: Which is Best For Colorado Homes?

As a homeowner, you'll face many decisions, and choosing the right roofing material is among the most crucial. This is particularly true if you're residing in the hail-prone state of Colorado. This guide aims to simplify your decision by comparing Class 3 and Class 4 shingles - helping you select the best for your home.

Understanding Shingle Ratings: What Do Classes Mean?

The roofing industry developed a standardized test in the mid-1990s to evaluate the impact resistance of their products. This test, known as the Underwriters Laboratory 2218 (UL 2218) or the steel ball test, assigns one of four ratings to a shingle, with Class 4 being the highest possible rating.

The testing involves dropping steel balls of different diameters from varying heights onto the shingles to simulate hail pellets. As you might guess, a higher class indicates better impact resistance. 

A roof achieves a Class 3 rating if the sample remains uncracked when struck twice in the same area by a steel ball with a diameter of 1.75 inches. For a roof to receive a Class 4 rating, it should show no damage when hit twice in the same spot by a steel ball measuring 2 inches in diameter.

Breaking Down Class 3 and Class 4 Shingles

Let's delve into the specific features of Class 3 and Class 4 shingles - key distinctions every Colorado homeowner should be aware of:

• Durability: Class 4 shingles, with their superior impact resistance, are ideal for areas frequently hit by severe weather, like much of Colorado. Meanwhile, Class 3 shingles, while still robust, are better suited for areas with milder weather patterns.

• Hailstorm Resilience: Colorado is in the heart of "Hail Alley," which experiences the highest frequency of large hail in North America. Class 4 shingles have the highest rating for impact resistance, making them an ideal choice to withstand hail damage.

• Cost: Class 4 shingles carry a higher price tag due to their increased durability and lifespan. Yet, they may offer more value over time given their extended longevity and potential insurance benefits.

• Insurance: It's worth noting that several insurance companies offer premium reductions for homes equipped with Class 4 shingles, thanks to their enhanced resistance to damage. Contact your insurance provider to learn more.

In Colorado, Class 4 shingles are often the most recommended for homeowners due to their superior impact resistance. 

Making an Informed Decision

The choice between Class 3 and Class 4 shingles hinges on your specific needs, budget, and local weather conditions. While Class 4 shingles may initially cost more, their durability and potential insurance benefits could make them a more cost-effective choice in the long run. However, if your area doesn't frequently experience severe weather, Class 3 shingles might be a more economically sensible option.
