What is Class 4 Hail Rating and Why Does it Matter?

[vc_row padding_top=”0″ padding_bottom=”0″][vc_column][vc_column_text]When a shingle or other roofing material is listed as having a Class 4 hail rating it means it has the highest impact resistance rating available. This is a classification that is given after the material has undergone rigorous testing as defined by UL, a global safety certification company that conducts performance tests on a wide variety of products, including roofing shingles.

Earning a Class 4 hail rating

The UL 2218 Class 4 designation is earned only after a shingle can withstand the test that simulates the impact of a two-inch sized hail stone. In the test, a steel ball is dropped onto the shingle two times in the same spot. The shingle is then closely examined for damage. If it shows any sign of cracking or breaking, or even granule loss, the shingle will fail the test.

Class 4 impact resistance isn’t just for asphalt shingles either. Other roofing materials must be able to perform as well, including metal, composites and commercial roofing systems like single-ply roofing.

Why it matters

A recent report released in fall 2021 showed that Texas is becoming more vulnerable to severe weather due to climate changes.  Spectrum News reported that Texas is getting hotter, and “the severity and frequency of natural disasters are expected to increase, having an effect on everything from infrastructure to public health.”

Dr. John Nielsen-Gammon, the report author and atmospheric sciences professor at Texas A&M University, told Spectrum News, “Extreme rainfall getting worse because of higher temperatures and changes in weather patterns, droughts getting worse because of greater evaporation, those all get connected to those temperature changes.”
