Galvalume-coated steel is the workhorse metal in Flower Mound, the material inside most metal roofing systems, balancing strength, corrosion resistance, and cost.
Most metal roofs in Flower Mound are steel at the core: a galvalume coating of aluminum-zinc alloy over steel, topped with paint systems warrantied in decades. The panel profile, 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 provide free written estimates for steel roofing and document every inspection with photos. Deductibles are never waived on our jobs, as Texas law requires, and Cedar Crest is not a public adjuster.
What Flower Mound’s hail means for a steel roof
Steel’s strength matters here because the storms keep coming. Hail an inch or larger has hit within 7 miles of Flower Mound in 14 separate years since 2006, and on 15 days the stones reached golf-ball size or more. Steel under a galvalume coat may take cosmetic dents in storms like that, yet it keeps shedding water, which is the trade most metal owners accept. On the housing side, only 5 percent of local homes were built before 1980, so the old-structure problems common in older towns are less likely here, though we still check the deck on every job. Flower Mound is in Denton County, and our steel crews also serve Double Oak and Highland Village.

Common questions about steel / galvalume roofing in Flower Mound
Will a steel roof rust in Flower Mound?
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 Flower Mound does not have.
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?
