Common commercial roof types
TPO
A white single-ply membrane with heat-welded seams. Common on newer low-slope buildings.
EPDM
A rubber membrane often used on flat roofs. See TPO vs. EPDM roofing.
PVC
A single-ply membrane with welded seams, often used where chemical resistance matters.
Metal
Standing seam or panel systems that need fastener and seam checks over time.
Shingle
Steep sections on offices, churches and mixed-use buildings.
Where commercial roofs usually leak
Seams between membrane sheets.
Flashing at walls, parapets and edges.
Curbs around rooftop HVAC units.
Pipe and conduit penetrations.
Drains and scuppers clogged with debris. Read about flat roof drainage systems.
Areas where foot traffic has worn the membrane.
Edge metal and coping that lifted in high wind.
Storm risk for Mansfield properties
Mansfield covers parts of Ellis County, Johnson County and Tarrant County. NOAA's Storm Prediction Center logged 99 hail reports within 10 miles of the city from 2015 through 2024. Of those, 27 were 1.75 inches or larger. The biggest was 5 inches on June 12, 2023.
Hail that large can puncture membranes, crush the insulation under them and damage rooftop units. On a flat roof, water does not drain fast, so a small puncture can let in a lot of water. Damage may also stay hidden under the membrane, showing up only as wet insulation found with a moisture check.
Because hail near Mansfield came in only 5 of those 10 years, maintenance budgets can slip in quiet years. A plan that includes a check after every storm helps avoid surprises.
A practical maintenance routine
Spring and fall inspections
Walk the field, seams, edges, drains and equipment.
After every storm
Check for punctures, displaced materials and blocked drains.
Keep drains clear
Remove debris so water does not pond.
Repair small issues fast
Seal small openings before water spreads into insulation.
Repair, restore or replace
Not every old flat roof needs to be torn off. If the membrane is still attached and the insulation under it is dry, targeted repairs or a restoration can extend its life. If large areas are wet, the membrane is brittle or leaks keep moving around, replacement is usually the better use of money.
The answer comes from data, not guesses. A close inspection with photos, and in some cases a moisture survey, shows how much of the roof is still sound. Our post on signs a commercial roof needs replacement lists the common markers.

Frequently Asked Questions
How do I know if hail damaged my flat roof?
Look for dents on rooftop units and edge metal, punctures or bruises in the membrane and debris near drains. Some damage hides under the membrane, so a close inspection with photos, and sometimes a moisture check, is the best way to know after a storm.
Can a commercial roof be replaced in phases?
Often, yes. Large roofs can be replaced section by section to fit budgets and keep parts of the building in use. The plan needs careful tie-ins between old and new sections so water does not get in at the seams.
When does a flat roof need replacement instead of repair?
When leaks come from many areas, large sections of insulation are wet or the membrane is too brittle to patch. Our article on signs a commercial roof needs replacement lists the common markers to watch for.
