What Are Class 4 Materials — And Why Should Colorado Homeowners Care?
When it comes to roofing in Colorado, durability isn’t optional — it’s essential. Hailstorms, high winds, and rapid weather changes put constant stress on your roof. That’s why more homeowners across El Paso County are choosing Class 4 impact-resistant shingles for stronger, longer-lasting protection.
But what exactly does “Class 4” mean, and is it really worth the upgrade? Let’s break it down.
What Is a Class 4 Shingle?
The term “Class 4” refers to the highest possible impact resistance rating in roofing materials. It comes from a standardized test by Underwriters Laboratories (UL 2218). In this test, a 2-inch steel ball is dropped from 20 feet onto the shingle — twice in the same spot.
To earn a Class 4 rating, the shingle must show no signs of cracking, tearing, or rupturing after impact. In other words, Class 4 shingles are built to take a beating — and keep protecting your home.
Why Class 4 Materials Matter in Colorado
If you live in Colorado Springs, Falcon, Peyton, or any surrounding area, you already know how common hailstorms are. The 80831 and 80908 zip codes, in particular, are high-risk zones. Choosing a Class 4 shingle can mean the difference between needing a full roof replacement after a storm — or just brushing off a few stray leaves.
Here’s why it matters:
Fewer insurance claims over time
Lower risk of leaks and interior damage
Potential savings on insurance premiums (many companies offer discounts for Class 4 roofs)
Peace of mind during every thunderstorm warning

Is Metal Roofing Class 4?
Yes — standing seam metal roofing is also considered Class 4 impact-resistant. In fact, metal roofing performs exceptionally well in Colorado’s high-stress environment.
Here’s why metal is worth considering:
Naturally strong against hail, snow, and wind
Extremely low maintenance
Lifespan of 40–70 years

We frequently install Class 4-rated metal roofs for rural homes across Falcon and Black Forest, especially on properties with wide exposures to storms.
Should You Upgrade to a Class 4 Roof?
If your current roof is older, showing signs of wear, or if you’re planning to stay in your home long-term — a Class 4 upgrade is a smart move. The upfront cost is slightly higher, but the long-term savings on repairs and insurance often make it more than worthwhile.
Moreover, many HOAs in neighborhoods like Wolf Ranch, Cordera, and Meridian Ranch accept and encourage Class 4 materials due to its proven durability and performance.
