Class 4 impact-resistant shingles are the highest impact rating shingles carry, and in Flower Mound (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 UL 2218, the impact test that drops steel balls on the product to approximate severe hail, and it has to come through without cracking. For a Flower Mound homeowner that rating pays off in two ways: fewer storm-damaged roofs over the life of the system, and the wind/hail premium discount that many Texas carriers offer for Class 4 roofs. Ask your carrier for its specific discount before you decide, and we will document the product rating for your policy file either way.
Our estimates are free and written, and every inspection is documented with photos. We never waive a deductible, since Texas law does not allow it, and we are not a public adjuster. Our job is the roof; the claim stays between you and your carrier.
Why Flower Mound Hail Makes the Class 4 Rating Count
The local hail record is the core of the Class 4 argument. Within 7 miles of town there have been 34 days with hail an inch or larger since 2006, and 15 of those days brought golf-ball size stones or bigger. The largest stone on record here measured 4.25 inches on June 11, 2023. A test designed around severe hail is testing for exactly what this area produces.
The housing stock points the same way. The median home in Flower Mound was built in 1997, only 5 percent predate 1980, and 21 percent went up in 2010 or later, which puts many original roofs at the age where replacement comes up with plenty of hail seasons still ahead. That is the right moment to step up to an impact rating. We install Class 4 shingles across Denton County, including Highland Village and Double Oak, on the same crew schedule as Flower Mound.

Common questions about class 4 impact-resistant shingles in Flower Mound
Do Class 4 shingles make my roof hail-proof in Flower Mound?
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 Flower Mound?
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.
Is upgrading from builder-grade shingles worth it in Flower Mound?
Usually at the first replacement or claim: Class 4 impact-rated systems earn many Texas carriers' premium discounts, and newer communities' HOA standards generally approve them easily. The math works hardest on homes facing decades of DFW hail.
How often does hail hit Flower Mound?
