Flat and low-slope roofing is its own discipline in Dallas: membrane selection, seam engineering, and drainage decide whether a commercial roof reaches its rated life.
Dallas commercial buildings use the full membrane range: TPO for reflective single-ply economics, EPDM for 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 the question with evidence rather than preference. That assessment and the estimate that follows are free and in writing, with photos documenting what we find. Under Texas law we never waive deductibles, and we are not a public adjuster.
Choosing a Low-Slope System for a Dallas Building
Storm history narrows the choice. Dallas has logged 77 days since 2006 with hail at least an inch across within 13 miles, 25 days at golf-ball size, and inch-plus hail in all of the last 20 years. Single-ply membranes can show bruise fractures that a chalk circle will not catch, so after a storm we survey with instruments rather than rely on a walk. Drainage and rooftop equipment then decide which membrane holds up under the building’s actual use. The city’s building age shapes the rest of the conversation: with a median housing year of 1981, many roofs have been replaced before and carry patched decking and flashing from earlier owners, and a moisture survey decides restore versus replace. Flat-roof clients across Dallas County, including University Park and Cockrell Hill, are served by the same team.

Hail near Dallas
Hail is a regular event around Dallas. NOAA's Storm Events Database lists 77 separate days since 2006 with hail one inch or larger reported within 13 miles of the city, and on 25 of those days the stones reached golf ball size or bigger. Hail that size was reported in 20 of the last 20 years. The largest stones on record nearby measured 4.25 inches (grapefruit size) on May 24, 2011. The most recent report: 1.5-inch hail on June 2, 2026.
May 24, 2011: 4.25-inch hail (grapefruit size)
April 25, 2026: 3-inch hail (teacup size)
June 6, 2018: 3-inch hail (teacup size)
June 13, 2012: 3-inch hail (teacup size)
April 3, 2012: 2.75-inch hail (baseball size)
How old Dallas homes are
The median home in Dallas was built in 1981, and 48% of the city's 590,237 housing units predate 1980. Many of these houses are likely on their second roof or nearing the point where they need one.

Common questions about flat / low-slope roofing in Dallas
What is the best flat roof system in Dallas?
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.
Does this material suit older Dallas homes?
Often, with eyes open: older decks get inspected board by board before any system goes down, and weight or structural questions get answered before quoting. The material conversation starts with what your specific roof can carry.
How often does hail hit Dallas?
NOAA's Storm Events Database lists 77 days since 2006 with hail one inch or larger reported within 13 miles of Dallas, including 25 days with golf ball size stones or bigger. Hail that size was reported in 20 of the last 20 years. The most recent report was 1.5-inch hail on June 2, 2026.
How old are most homes in Dallas?
The median home in Dallas was built in 1981, according to the U.S. Census Bureau's American Community Survey. 48% of the city's housing units predate 1980 and 14% were built in 2010 or later. Most homes here are well past the life of their original roof.
