Commercial Roofing in Dallas
A commercial roof leak costs more than the repair. It costs inventory, tenant goodwill and business hours. GemSco helps Dallas owners and managers get ahead of it.

Hail and wind on a Dallas commercial roof
NOAA's Storm Prediction Center logged 58 hail reports within 10 miles of Dallas from 2015 through 2024, and ten of them were 1.75 inches or larger. On a low-slope roof, hail can fracture the surface, dent metal and crack skylights, and none of it shows from the parking lot.
Wind is the other half. It pulls at the perimeter, where edge metal and flashing hold the roof system down. A loose edge lets wind get under the surface, and a small lift can become a large one in the next storm.
Rooftop equipment adds risk. Every unit sits on a curb that pierces the roof, and technicians walking to it can tear flashing or leave debris that blocks drains. A roof with several units needs those curbs checked as closely as the open surface.
Where commercial roofs fail first
Perimeter edges
Edge metal and coping that loosen in wind and let water and air under the roof.
Penetrations
Pipes, vents and curbs for rooftop units, sealed with materials that dry out in the heat.
Drains and scuppers
Clogged drains leave ponding water that finds every weak seam.
Seams
Joints in the roof surface that open with daily heat expansion.
Metal panels
Fasteners that back out and seams that separate on metal buildings. More on metal roofing.
Skylights
Domes and panels that crack in hail and leak where they meet the curb.

Water still standing on the roof two days after rain

One contractor for mixed portfolios
GemSco is family owned, licensed and insured, and an elite contractor for Owens Corning and GAF. We handle commercial roofing and residential work across DFW, Houston, Austin and San Antonio, including low-slope and flat roofs, metal, tile and shingle. Estimates are free.
Many Dallas owners hold both kinds of property: a building with a flat roof and pitched canopies, or a few commercial sites next to rental houses. One contractor for all of it means one point of contact. For an active leak, see commercial roof repair; for homes, see Dallas roofing.
Before any replacement, ask three things: how the new roof will drain, how the edges will be secured against wind and how rooftop units will be handled during the work. Those answers say more about a bid than the price line does.
Frequently Asked Questions
How often should a commercial roof be inspected?
A common practice is twice a year, in spring and fall, and after any major hail or wind storm. Regular checks catch clogged drains, open seams and loose edges before they leak. The photos also give you a dated record of the roof's condition, which helps with budgeting and with any future storm claim.
Can a commercial roof be repaired instead of replaced?
Often, yes. If the leaks are local and the insulation underneath is dry, targeted repairs to seams, flashing and penetrations can extend the roof's life. When moisture has spread through the insulation or the surface is failing across the roof, replacement is usually the better spend. The inspection shows which case you are in.
Do you work with property managers who are not on site?
Yes. We share photos and a written estimate so a manager or owner can go over the findings remotely and approve the scope. We coordinate access and timing with whoever is on site, so tenants know what to expect before the work begins and nobody is surprised by a crew on the roof.
