Commercial Roofing Services in Midlothian
A commercial roof protects inventory, equipment and the people inside. In a hail area, keeping it sound takes a plan, not just a phone number.

Ellis County weather and commercial roofs
NOAA's Storm Prediction Center logged 90 hail reports within 10 miles of Midlothian from 2015 through 2024. Nineteen were 1.75 inches or larger, and the largest measured 4.0 inches on June 12, 2023. Large hail was reported in 2015, 2017, 2021, 2023 and 2024.
On a low-slope or flat roof, hail strikes the whole surface. Membranes can bruise or crack, coatings can chip, and metal parts such as edge trim, vents and rooftop units can dent. Damage on the membrane is often hard to see. Water then travels under it and soaks the insulation before a leak shows inside.
For owners and managers, the practical answer is a survey after every large storm and a written record of the roof's condition each year. That record helps both with planning and with any insurance conversation.
Signs to watch for from inside and out
Stained or sagging ceiling tiles.
Water sitting on the roof long after rain ends.
Blisters, wrinkles or open seams in the membrane.
Rust, loose fasteners or gaps at metal panel laps.
Debris piled at drains and scuppers.
Common commercial roof systems
TPO
A white single-ply membrane with welded seams. Compare it in TPO vs. EPDM roofing.
EPDM
A rubber membrane that is flexible and long used on low-slope roofs.
Metal
Panels on shops and warehouses, where seams and fasteners need regular care. See metal roof maintenance.
Steep-slope
Shingle, tile and stone-coated roofs on offices and retail buildings.
Coatings
Some sound roofs can be coated to extend service life, once seams and damage are repaired.
Repair, recover or replace: how to choose
A repair targets a known problem: a punctured patch of membrane, a split seam, a loose flashing detail at a rooftop unit. It is the right call when the rest of the roof is sound and the insulation underneath is dry.
A recover adds a new membrane over the existing roof. It can save the cost of a full tear-off, but only when the deck and insulation are dry and in good shape. Trapping wet insulation under a new membrane causes bigger problems later.
Replacement removes the old system down to the deck. It makes sense when damage is widespread, wet insulation is found across large areas or the roof has reached the end of its service life. Our guide on flat roof drainage systems is worth reading before any of the three, since poor drainage shortens the life of every option.

Frequently Asked Questions
Can a flat roof be repaired in sections?
Yes, when damage is limited and the insulation below is dry. Patches and seam repairs work well on a sound roof. If wet insulation is spread across large areas, sectional repair stops making sense and a recover or replacement is the better option.
How soon after a storm should we survey the roof?
As soon as it is safe, especially after hail. Early photos help separate new damage from old, and quick repairs keep water out of the insulation. Do not send staff onto the roof; a roofer can do it with proper safety gear.
Do you work on metal buildings?
Yes. GemSco works on metal roofs as well as low-slope membranes and steep-slope commercial roofs. Common work includes tightening or replacing fasteners, sealing seams and laps and repairing storm damage. A survey shows what the building needs.
