What is UL 2218 Class 4 Impact Resistance Rating?
Prior to 1996, there was no defining standard existed to distinguish how well a roofing material can withstanding impact. In 1996, several property insurance industry experts teamed with the Institute of Business and Home Safety (IBHS) and the Underwriter’s Laboratory (UL) to develop the UL 2218 classification.
UL 2218 set a national standard for roof impact resistance by rating materials from Class 1 through Class 4.
Class 4 rating is the highest and the toughest. During a Class 4 impact resistance test on asphalt shingles, a 2” diameter steel ball is dropped from 20 feet onto the shingle to simulate the impact of hailstones. This is done twice in the same spot. This process is then repeated on six different spots. A shingle passes the test if it does not show any visible evidence of tearing, fracturing, cracking and splitting.
Are Class 4 asphalt shingles hail proof?
The short answer is “no”. No asphalt roofing material is completely hail proof, however, homeowners in hail prone areas can reduce their risk of impact damage by installing Class 4 shingles.
