Roof types common on commercial buildings

Single-ply membranes

TPO and EPDM are widely used on flat and low-slope roofs. Our guide on TPO vs. EPDM roofing compares them.

Modified bitumen

Layered asphalt sheets, often on older or smaller buildings.

Metal panels

Common on shops, warehouses and industrial buildings. Fasteners and seams need regular checks.

Shingle roofs

Some offices and small commercial buildings use steep-slope shingle roofs.

Warning signs to act on

Stains on ceiling tiles or drips inside.

Water that stays on the roof for days after rain.

Blisters, splits or open seams in the membrane.

Loose or backed-out fasteners on metal panels.

Dented rooftop units and flashing after hail.

Clogged drains, gutters or scuppers.

Hail and commercial roofs in Red Oak

Red Oak is mainly in Ellis County. NOAA's Storm Prediction Center logged 77 hail reports within 10 miles of Red Oak from 2015 through 2024, and 15 of them were 1.75 inches or larger. Large hail fell in 2015, 2021, 2023 and 2024. The biggest stone, 3.75 inches, came on June 14, 2023.

On a flat roof, hail can puncture membranes, crack seams and crush the insulation underneath. On metal roofs, it dents panels and can loosen fasteners. Damage on a commercial roof is often invisible from the ground, and water that gets in can travel far under the surface before it shows inside. After any storm with large hail, the roof should be walked and checked.

A maintenance routine that works

1

Baseline inspection

Record the roof's current condition with photos of every section.

2

Scheduled checks

Inspect in spring and fall, plus after major storms. Our post on a commercial roof maintenance plan lays out a routine.

3

Keep water moving

Clear drains and scuppers so water does not pond. See flat roof drainage systems.

4

Repair quickly

Small punctures and open seams are cheap to fix early.

5

Plan replacement in advance

Budget and schedule before the roof fails, not after.

Keeping the business running during roof work

Roof work on an occupied building takes planning. Noise, deliveries, crane or lift access and safety zones all affect staff and customers. Sections can often be done one at a time so most of the building stays in use. Work can also be timed around busy seasons or shifts.

Talk through these details before the contract is signed, not on the first day of work. Our post on how to reduce business disruption during roof repairs has a checklist you can share with your team.

Working with GemSco

Every commercial building is different, so the right plan depends on the roof type, its age and how the building is used. Some roofs need targeted repairs. Others are past the point where repairs make sense. An honest inspection tells you which.

Frequently Asked Questions

How can I tell if hail damaged my building's roof?

Check inside for new stains and drips first, then look for dents on rooftop units and gutters. Membrane punctures and crushed insulation usually need a close inspection on the roof itself. A roofer can walk the surface, photograph each damaged area and give you a written report.

Can a metal commercial roof be repaired instead of replaced?

Often, yes. Loose fasteners, failed seams and small damaged sections can be repaired. If rust is widespread or many panels are damaged, replacement may be the better option. An inspection shows how much of the roof is still sound.

What causes ponding water on a flat roof?

Common causes are clogged drains, a sagging deck or insulation that has compressed over time. Water that sits for days adds weight and wears the membrane faster. Clearing drains may solve it. If not, the roof may need re-sloping in that area.
