Has There Been an Upgrade in Class 3 Impact-Resistant Shingles?

Impact-resistant shingles are rated by a steel-ball drop test (UL 2218) from Class 1 to Class 4, with Class 4 the highest. In a hail-prone market like Kansas City, the rating matters.

What has changed

Manufacturers have widened the range of impact-rated products. Class 4 options that used to be limited to a few premium lines are now available across more colors and price points, and several use polymer-modified asphalt that stays flexible and resists cracking.

Class 3 versus Class 4

In practice, most owners choosing an impact-rated shingle today go straight to Class 4. The cost difference is modest, and Class 4 is the rating that insurance carriers most often recognize.

Insurance considerations

Some carriers offer premium discounts for Class 4 roofs; policies vary, so ask your agent. Note that impact rating reduces hail damage; it does not make a roof hail-proof.

The bottom line

If you are replacing a roof in this area, ask for the impact-rated options up front. The added cost is small against the price of another replacement.
