Flat and low-slope roofing is its own discipline in Lewisville: membrane selection, seam engineering, and drainage decide whether a commercial roof reaches its rated life.
Lewisville commercial buildings cover the full membrane range: TPO’s reflective single-ply economics, EPDM’s proven rubber, PVC where grease and chemicals are present, modified bitumen and built-up systems on buildings that have trusted them for decades, coatings that restore sound roofs, and structural metal. The right system follows the building’s use, traffic, equipment, drainage and budget horizon, and our assessment answers that with evidence rather than preference.
It starts with a free written estimate and a photo-documented inspection. We never waive deductibles (Texas law), and we are not a public adjuster.
Choosing a low-slope system for Lewisville weather
Every flat roof in Lewisville answers to the same storm record. Within 7 miles, hail an inch or larger has fallen on 34 days since 2006, and it has shown up in 15 of the last 20 years. The 3.0-inch hail of June 11, 2023 is the high mark. Single-ply membranes can bruise without visible marks, so instrument surveys and photo records matter more here than a quick walk across the roof.
Budget horizon matters as well. Much of the city was built between 1980 and 2009, and a roof from that era may be a restoration candidate rather than a tear-off. We serve low-slope roofs across Denton County, from The Colony to Highland Village.

Common questions about flat / low-slope roofing in Lewisville
What is the best flat roof system in Lewisville?
The one matched to your building. TPO leads new low-slope installs on economics and reflectivity, but restaurants argue for PVC, and a sound existing roof often argues for a coating instead of anything new.
How long do commercial flat roofs last?
System- and maintenance-dependent: single-ply membranes commonly rate twenty to thirty years, and twice-yearly maintenance is what lets a roof actually collect its rating.
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?
