Class 4 impact-resistant shingles are the highest impact rating shingles carry, and in Dallas (squarely in DFW hail territory) they are the upgrade that most often pays for itself through insurance premium discounts.
A Class 4 shingle has passed the UL 2218 impact standard: a steel ball is dropped on the product to approximate severe hail, and the shingle has to come through without cracking. For a Dallas homeowner that pays off in two ways. You get fewer storm-damaged roofs over the life of the system, and many Texas carriers discount wind/hail premiums for homes roofed with Class 4 products. Ask your carrier for its specific discount before you decide; we document the product rating for your policy file either way. Estimates are free and written, every inspection is documented with photos, and we never waive a deductible, which Texas law prohibits. We are also not a public adjuster.
Why Dallas Hail Makes the Class 4 Case
Since 2006, the area within 13 miles of Dallas has logged 77 days with hail an inch or larger, and 25 of those days brought golf-ball-size stones or bigger. Inch-plus hail has shown up in each of the last 20 years, and the largest stone on record measured 4.25 inches on May 24, 2011. That frequency is the argument for impact rating: standard laminates open up where Class 4 shingles take a bruise, and the difference shows at the adjuster meeting. The housing stock adds a second reason to be careful. The median Dallas home was built in 1981, 48 percent predate 1980, and only 14 percent date from 2010 or later, so many roofs moving to Class 4 sit on established houses whose original decking deserves inspection before anything new goes on. We work throughout Dallas County, and the same crews install impact-rated shingles in Highland Park and University Park.

Common questions about class 4 impact-resistant shingles in Dallas
Do Class 4 shingles make my roof hail-proof in Dallas?
No. Class 4 is the highest impact rating, not immunity. Large hail can damage any roof. The rating means significantly better resistance to the hail sizes DFW sees most often.
How much do I save on insurance with Class 4 in Dallas?
It varies by carrier and policy. Texas insurers commonly discount the wind/hail portion of premiums for certified Class 4 roofs. Your agent can quote the exact discount; bring the product certification we provide.
Does this material suit older Dallas homes?
Often, with eyes open: older decks get inspected board by board before any system goes down, and weight or structural questions get answered before quoting. The material conversation starts with what your specific roof can carry.
