Blisters, ridges or shrinking at the edges.
Punctures near rooftop units and service paths.
Clogged drains, scuppers or gutters.
Wet or soft insulation underfoot.
Cracked sealant at curbs, pipes and pitch pans.
Loose metal edge or coping after high wind.
Hail exposure in Corinth and Denton County
Corinth is in Denton County, part of the Dallas-Fort Worth metro area. NOAA's Storm Prediction Center logged 178 hail reports within 10 miles of the city from 2015 through 2024. Of those, 57 were 1.75 inches or larger, and the largest measured 4.25 inches on March 26, 2017.
Flat roofs take hail on a wide, exposed surface. Impact can crack aging membranes, crush insulation boards and damage metal edge and coping. Because water does not run off as fast as on a sloped roof, every small break gets more time to leak. With large hail reported in 7 of the last 10 years, a commercial roof here should be walked after each major storm, not just when a tenant calls.
Systems and their trade-offs
TPO
Light-colored single-ply with welded seams. Popular for its reflective surface.
EPDM
Rubber membrane, flexible in temperature swings. Seams and flashings need attention. Compare in TPO vs. EPDM roofing.
Modified bitumen
Layered and tough, good where there is foot traffic.
Metal
Long life on low-slope and steeper commercial roofs. Watch fasteners and seams.
Recover option
When insulation is dry and the deck is sound, a new membrane can sometimes go over the old one instead of a full tear-off.
How a commercial project runs

Do the work
Repair, recover or replace based on what the survey shows.
Set a maintenance rhythm
Regular checks keep small problems from growing. Our commercial roof maintenance plan explains what to include.
Commercial work with GemSco
Keep a roof file for each building: the membrane type, the install year, manufacturer documents, every repair invoice and photos after each storm. Owners, managers and insurers all ask for the same information sooner or later. A file ready to share shortens every conversation.
Rooftop equipment also needs a plan. HVAC units, pipes and vents pass through the membrane, and service crews walk to them in all weather. Walk pads, clear routes and sealed curbs reduce wear. When a unit is replaced, the roof around it should be checked and reflashed.
GemSco handles residential and commercial roofing, including low-slope and flat roofs. We are fully licensed and insured, with 20+ years of experience, and estimates are free. Learn more on our commercial roofing page. For storm-related work, see hail damage roof repair in Corinth.
Frequently Asked Questions
How do I know if hail damaged my flat roof?
Look for dents in metal edges, rooftop units and vents, then check the membrane for cracks, bruises or punctures. Damage to insulation under the membrane is harder to see. A roofer can walk the roof, take photos and check suspect areas for moisture.
When does a flat roof need replacement instead of repair?
When wet insulation covers large areas, the membrane is brittle or shrinking, or leaks keep returning after repairs. A moisture survey shows how far the water has spread. Read signs a commercial roof needs replacement for the common markers owners and managers should watch for.
Should a commercial roof be checked after every storm?
After any storm with large hail or high wind, yes. Flat roofs hide damage well, and slow leaks can soak insulation for months. A quick walk with photos after each event keeps records current and catches problems while repairs are still small.
