Class 4 impact-resistant shingles are the highest impact rating shingles carry, and in Rowlett (squarely in DFW hail territory) they are the upgrade that most often pays for itself through insurance premium discounts.
Class 4 is a rating under the UL 2218 standard: to earn it, a shingle has to come through a steel-ball impact test built to approximate severe hail without cracking. That pays off in two ways. You file fewer storm claims over the life of the roof, and many Texas carriers discount wind and hail premiums for homes carrying Class 4 rated products. Call your carrier for their exact discount before you choose; 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 because Texas law does not allow it. We are a roofing contractor, not a public adjuster.
Why Rowlett roofs make the case for Class 4
Hail is the reason this product exists, and Rowlett gets plenty of it. Within 6 miles of the city, hail an inch or larger has fallen on 28 separate days since 2006, and 9 of those days brought golf-ball size stones or bigger. It showed up in 16 of the last 20 years. The largest stone on record here measured 4.0 inches on April 11, 2016.
The housing makes the timing relevant. The median Rowlett home dates to 1997, and 66 percent were built between 1980 and 2009, so a large share of roofs in this corner of Dallas County come up for replacement over the same stretch of years. Replacement day is the natural time to step up to Class 4. Our crews install the same shingles in Sachse and Rockwall.

Common questions about class 4 impact-resistant shingles in Rowlett
Do Class 4 shingles make my roof hail-proof in Rowlett?
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 Rowlett?
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.
Should we match the original material when re-roofing in Rowlett?
Not automatically. A roof on its second or third cycle is a chance to rethink: Class 4 asphalt for the insurance math, metal or premium systems where the home and horizon justify them. We quote the honest options against your actual house.
