Galvalume-coated steel is the workhorse metal in Lewisville, the material inside most metal roofing systems, balancing strength, corrosion resistance, and cost.
Under the paint, most metal roofs in Lewisville are steel: a steel core with a galvalume coating of aluminum-zinc alloy, finished with paint systems warrantied in decades. The profile on top of that steel, whether standing seam, R-panel, or corrugated, matters more to performance than the steel itself, which is why our guides are organized by profile.
We quote galvalume work in Lewisville with free written estimates, and each inspection is backed by photos. Texas law prohibits waiving an insurance deductible, so we never do it, and we are not a public adjuster.
Galvalume Steel and the Lewisville Storm Record
Steel is the metal that handles Lewisville hail with the least drama. Within 7 miles of the city there have been 34 days of one-inch or larger hail since 2006, including 14 at golf-ball size or above. A galvalume panel may pick up cosmetic dents in that kind of weather, but the coated steel keeps shedding water, which is the trade most metal owners gladly accept.
Lewisville’s housing is conventional stock: only 14 percent of homes were built before 1980, and the median home dates to 1997. On those houses, choosing steel is less about structure and more about profile and paint color. Lewisville is part of Denton County, and we carry the same galvalume work into The Colony and Lake Dallas.

Common questions about steel / galvalume roofing in Lewisville
Will a steel roof rust in Lewisville?
Modern galvalume coatings resist corrosion for decades; the paint system on top extends that further. Cut edges and scratches are the care points, which is an installation-quality question.
Steel vs aluminum: which is better here?
Inland DFW favors steel: stronger against hail and cheaper. Aluminum's corrosion advantage matters most in coastal salt air, which Lewisville does not have.
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.
How often does hail hit Lewisville?
NOAA's Storm Events Database lists 34 days since 2006 with hail one inch or larger reported within 7 miles of Lewisville, including 14 days with golf ball size stones or bigger. Hail that size was reported in 15 of the last 20 years. The most recent report was 1-inch hail on June 8, 2025.
How old are most homes in Lewisville?
The median home in Lewisville was built in 1997, according to the U.S. Census Bureau's American Community Survey. 14% of the city's housing units predate 1980 and 23% were built in 2010 or later. Many homes here are reaching the age when original roofs come due.
