Commercial Roofs in Richmond, TX: Flat, Low-Slope and Built for Storms
A business roof has different problems than a house: big flat areas, standing water, rooftop units and tenants who cannot stop working while it gets fixed.

Common low-slope roof types
Single-ply membranes
Large sheets such as TPO or EPDM, either welded or glued at the seams. Our comparison of TPO vs. EPDM roofing explains the trade-offs.
Modified bitumen
Asphalt-based rolls in layers, common on older flat roofs and small buildings.
Metal panels
Used on low-slope warehouses and shops, with seams and fasteners that need periodic checks.
Coatings
Liquid layers applied over a sound existing roof to seal it. They do not fix a wet or failing deck underneath.
Hail and water on Richmond business roofs
NOAA's Storm Prediction Center logged 19 hail reports within 10 miles of Richmond from 2015 through 2024. Five were 1.75 inches or larger, and the biggest reached 2.5 inches on May 9, 2019. On a flat roof, that kind of impact can puncture a membrane or crush the insulation board under it. The surface may look intact while water slowly seeps in.
Richmond sits mainly in Fort Bend County, where heavy Gulf rains are common. Flat roofs depend on drains, scuppers and a slight pitch to move that water off. When a drain clogs or the deck sags, water ponds and finds every seam. Our article on flat roof drainage systems covers the fixes.
How a commercial roof project should go
Walk the roof and the interior
Note leaks inside, ponding areas, damaged seams and the condition of rooftop units.
Check what is under the surface
Wet insulation is the hidden cost on flat roofs. Finding it early decides between repair, restoration or replacement.
Plan around your business
Work can be phased by section so tenants and customers keep using the building. See how to reduce business disruption during roof repairs.
Written scope and estimate
Materials, areas covered and any deck or drain work listed in writing.
Signs a commercial roof needs attention
Water stains on ceiling tiles after rain.
Puddles that stay on the roof two days after a storm.
Blisters, splits or open seams in the membrane.
Loose flashing around rooftop units and walls.
Rising cooling costs from wet insulation.
Dents in rooftop unit housings, vent caps or metal edge trim after a storm.
Membrane pulling away from parapet walls or curbs.
Gravel or debris washed into one corner, a sign water is collecting there.
Planning ahead
Repair, restore or replace is the big question on any commercial roof. A repair fixes a few seams or a damaged area. Restoration, such as a coating over a dry roof, adds years without a tear-off. Replacement is the answer when wet insulation is widespread or the deck is failing. Our article on signs a commercial roof needs replacement helps you tell which one you are facing, and a moisture check is what settles it.
Regular checks, ideally in spring and fall and after big storms, keep small issues from turning into a full tear-off. A simple commercial roof maintenance plan is a good start. GemSco is fully licensed and insured, with 20+ years on residential and commercial roofs, including low-slope and flat systems. See our commercial roofing page or our work in Richmond.
Frequently Asked Questions
How do I know if hail damaged my flat roof?
Look for dents in metal parts, crushed spots or small tears in the membrane, and new leaks inside. Many hail hits on a flat roof are hard to see because the damage is in the insulation below. A roofer can cut a small test sample or use moisture readings to check, then document it with photos.
Is a coating a cheaper way to fix an old flat roof?
A coating can extend the life of a roof that is still dry and sound underneath. It will not fix wet insulation, a sagging deck or failed seams. Before choosing one, have the roof checked for trapped moisture, because sealing water in can make the problem worse.
Can work be done without closing my business?
Usually yes. Crews can work in sections, keep entrances clear and schedule the noisiest steps outside peak hours. Tell your roofer about deliveries, customer traffic and sensitive equipment before work starts so the plan fits how the building is used.
