Class 4 impact-resistant shingles are the highest impact rating shingles carry, and in Lewisville (squarely in DFW hail territory) they are the upgrade that most often pays for itself through insurance premium discounts.
Class 4 is a test result, not a marketing tier. Under UL 2218, a shingle has to take a steel-ball strike that approximates severe hail without cracking. On a Lewisville home that pays off two ways: the roof comes through more storms intact over its life, and many Texas carriers discount wind and hail premiums when the roof carries a Class 4 rated product. Ask your carrier for their specific discount before you choose; we document the product rating for your policy file either way.
Estimates are free and written, and every inspection is documented with photos. We never waive a deductible, which Texas law prohibits, and we are a roofing contractor, not a public adjuster.
Why Lewisville homeowners keep asking about Class 4
The hail record explains the interest. Within 7 miles of Lewisville, hail an inch or larger has fallen on 34 days since 2006, and golf-ball size or larger on 14 of them. It has shown up in 15 of the last 20 years, and the largest stone measured 3.0 inches on June 11, 2023. Standard laminates open up under that kind of impact, while Class 4 shingles tend to bruise, and the difference shows at the adjuster meeting.
The housing stock adds a second reason. The median Lewisville home was built in 1997, and 63 percent went up between 1980 and 2009, so a large share of Denton County roofs here are old enough that the next replacement is a real grade decision. Another 23 percent are 2010 or newer, and only 14 percent predate 1980. Our crews run the same Class 4 installs in Highland Village and The Colony.

Common questions about class 4 impact-resistant shingles in Lewisville
Do Class 4 shingles make my roof hail-proof in Lewisville?
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 Lewisville?
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.
Do you install this on shops and outbuildings near Lewisville?
Yes. Barns, workshops, and outbuildings are first-class projects out here, not afterthoughts, and the material conversation (usually metal-forward) covers them alongside the house.
