A Class 4 shingle is one that passed the UL 2218 impact standard, a steel-ball drop test built to approximate severe hail without the shingle cracking. For Irving homeowners that pays off in two ways: fewer storm-damaged roofs over the life of the system, and the wind/hail premium discount many Texas carriers offer for Class 4 products. Call your carrier and get their specific discount before you commit; we document the product rating for your policy file either way. Every estimate is free and in writing, and every inspection is recorded in photos. We never waive a deductible, since Texas law prohibits it, and we are a roofing contractor, not a public adjuster.
Why Irving hail records favor Class 4 shingles
Since 2006, the area within 8 miles of Irving has logged 33 days of hail an inch or larger, and 9 of those days brought golf-ball-size stones or bigger. Hail at that size showed up in 15 of the last 20 years, and the largest stone on record here measured 4.25 inches on May 24, 2011. That is the exposure the UL 2218 test was written for. The housing side matters too. Irving’s median home was built in 1986 and 36 percent of homes date to before 1980, so many Dallas County roofs here have likely been replaced at least once already. When one of those comes due again, it is the logical moment to add impact resistance. The 14 percent built in 2010 or later will reach the same decision soon enough. Our crews install the same Class 4 lines in Coppell and Euless.
