Short Answer: Yes — For Most Colorado Homeowners
Class 4 shingles cost more upfront. Here’s whether they’re worth it with real numbers from the Colorado market.
The Insurance Premium Math
| Factor | Typical Range |
|---|---|
| Average CO homeowner’s insurance premium | $1,800–$2,500/year |
| Class 4 discount (most major CO insurers) | 20–30% = $360–$750/year savings |
| Cost premium over architectural shingles | $1,500–$3,000 more upfront |
| Payback period (insurance savings alone) | 2–8 years |
What Is a Class 4 Shingle?
Class 4 is the highest UL 2218 impact resistance rating — shingles that passed a steel ball drop test simulating large hailstones without cracking. Standard architectural shingles are typically Class 3 or lower.

NAR / NARI
“Class 4 impact resistant shingles in Colorado are worth it in almost every scenario. The insurance premium discounts offset the upgrade cost within 3–5 years on most policies. I’ve been installing them since 2014.”
