Flat and low-slope roofing is its own discipline in Richardson: membrane selection, seam engineering, and drainage decide whether a commercial roof reaches its rated life.
Commercial buildings in Richardson run the full membrane spectrum: TPO’s reflective single-ply economics, EPDM’s proven rubber, PVC where grease and chemicals live, 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, foot traffic, equipment, drainage, and budget horizon, and our assessment answers it with evidence instead of preference. That assessment comes with a free written estimate and an inspection documented with photos. Deductibles are never waived under Texas law, and we are not public adjusters.
Choosing a low-slope system for Richardson weather
Hail is the local variable every low-slope system has to answer for. Richardson has recorded hail an inch or larger within 6 miles on 36 days since 2006, in 14 of the last 20 years, with the largest stones reaching 3.0 inches on April 20, 2023. Flat roofs show that damage differently than shingles do; bruises and fractures in a membrane often cannot be seen on a casual walk, so our inspections are thorough and photographed. The city is also an established one, with 44 percent of its housing built before 1980, and existing flat roofs here may carry layered repairs worth sorting out before anyone picks a replacement system. We handle low-slope work throughout Dallas County, including Plano and Addison.

Common questions about flat / low-slope roofing in Richardson
What is the best flat roof system in Richardson?
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.
Should we match the original material when re-roofing in Richardson?
Not automatically. A roof on its second or third cycle is a chance to rethink: Class 4 asphalt for the insurance math, metal or premium systems where the home and horizon justify them. We quote the honest options against your actual house.
