Who We Are

The Story Behind GD Commercial Roofing's Commercial Roofing Crews In Union

The founders of GD Commercial Roofing spent years working for larger roofing companies before deciding the industry needed crews who'd actually stand behind their own installs a decade later, not just at closeout.

Every technician on a GD Commercial Roofing crew is licensed, background-checked, and trained on the specific manufacturer systems we install, from asphalt shingle lines to standing-seam metal.

Because roof failures rarely wait for a convenient hour, dispatch runs nights, weekends, and holidays with the same response priority as a Tuesday morning call.

We buy materials from manufacturers whose warranties survive an actual claim, not the cheapest line on a supplier's price sheet.

We also keep a small inventory of common shingle colors and metal profiles on hand locally, which shortens the wait between signing a quote and getting a crew scheduled.

Know The Warning Signs

What Our Inspectors Catch Before A Leak Ever Shows Up

A roof rarely fails without warning. These are the signs our crews spot most often on service calls across Union, usually months before an interior leak shows up. None of these checks require climbing onto the roof itself, just a careful look from the ground, the attic, or the gutter line.

Shingle Grit In The Gutters

Finding more than a handful of granules at the downspout typically signals a shingle that's already lost most of its wear layer. A quick gutter check after any hard rain costs nothing and catches this early.

Light Leaking Into The Attic

Turn off the attic light on a sunny day. Any pinpoint daylight through the decking means there's a path for water too, whether or not a stain has appeared yet. It takes five minutes and requires no special tools, just a flashlight and a moment of patience.

Shingles Curling At The Edges

Edges lifting or the shingle body cupping both point to asphalt that's dried out and lost its seal, which gives wind an easy edge to grab. Binoculars from the ground are usually enough to spot this without climbing anything.

A Springy Roof Deck

A soft or bouncy feel near a chimney or valley is a strong sign water has been sitting under the shingles longer than you'd think. This one's better left to a trained inspector rather than testing it yourself.

Flashing Separating From Walls

Gaps between flashing and the adjoining wall often go unnoticed until a hard rain finds them first. Binoculars help here too, focused on where the roofline meets any vertical wall or chimney.

A Creeping Cooling Bill

An underventilated roof forces the HVAC system to work harder, and that cost often lands on a utility bill months before any interior damage appears. Comparing this July's bill against last July's is a rough but useful gut check.

What We Install & Repair

Six Commercial Roofing Services Our Crews Handle In Union

None of the work below gets farmed out. The crew that inspects your roof is generally the crew that does the work. If a job falls outside these categories, ask anyway, there's a good chance we've handled something similar before.

24/7 Emergency Commercial Roofing experts in Union, SC

Emergency Leak & Storm Response

Active leaks get stopped first with an emergency tarp or membrane, then scheduled for permanent repair once materials are staged and the damage is fully assessed. We follow up within a couple of days to confirm the temporary fix held through the next round of weather.

Full Residential Reroofs

We replace any rotted decking found during tear-off, upgrade drip edge and flashing, and balance attic ventilation before the new roof ever goes down. Shingle color and style get picked before the old roof comes off, so materials are staged and there's no midday delay waiting on a decision.

Commercial & Low-Slope Systems

TPO, EPDM, and modified bitumen installs on flat commercial roofs get phased around business hours so the building stays weathertight overnight. Coating and recover options are also available for buildings that aren't ready for a full tear-off yet.

Storm & Hail Claims Support

We document wind and hail damage thoroughly enough that insurance claims tend to move faster and with fewer disputed line items. If an initial claim scope looks short, we'll provide a supplemental report with added photo evidence to support a fair settlement.

Inspections & Maintenance Plans

Maintenance plans cover gutter and valley clearing, sealant checks around every penetration, and a full moisture scan, all documented for future resale or insurance needs. Being on a plan means faster scheduling if a storm hits and the rest of the local roofing crews are slammed with calls.

Metal & Specialty Roofing

For a 40-plus year roofing system, we install standing-seam metal with concealed fasteners and proper thermal-movement clips rather than a shortcut screw-through method. We'll source a close color and profile match for partial tile or slate repairs rather than leaving an obvious mismatched section.

How A Job Runs

Four Stages Between Your Call And A Finished Roof

You Describe The Problem

Texting a couple of photos ahead of time often means our estimator shows up already knowing which materials to bring. There's no automated phone tree to get through first.

We Inspect In Person

We measure the deck, flashing, and ventilation, not just the visible shingle layer, so the quote reflects the real scope of the job. Most inspections take under an hour.

You Get Pricing In Writing

A line-item quote covering materials, labor, and disposal comes before any work starts, and it doesn't change unless hidden decking damage turns up mid-tear-off. You can take as long as you need to review it before scheduling.

Crew Installs, Then Walks It With You

We register the manufacturer warranty on your behalf and send a copy for your records along with our own workmanship guarantee. Payment isn't due until you've had a chance to see the finished work.

Why Homeowners Choose Us

Four Things We Do Differently In Union

Crews that chase storms into town tend to sell as many jobs as possible in a week and disappear before the first warranty call comes in. We're not going anywhere, and that changes how we price and build. Most of what separates us shows up months later, not on the day the crew leaves.

01
Written, Flat-Rate Pricing

No per-square guessing. Every quote is a written line-item breakdown of materials, labor, and disposal before a shingle comes off. Financing options exist if a full reroof doesn't fit into this month's budget.

02
Crews Staged Locally

Local staging means a crew is rarely more than a short drive from any job we quote in Union. That same local presence means a real person can meet you on-site after the job wraps if a question comes up.

03
Licensed, Insured, Certified

Manufacturer certifications for the shingle, metal, and membrane systems we install keep material warranties valid, not just decorative. Documentation gets shown before a contract is signed, not after a question comes up.

04
Honest Repair-Vs-Replace Calls

We'll say plainly when a targeted repair solves the problem instead of pushing a full reroof that isn't needed yet. That honesty is most of why past customers call us back for the next project.

The Guarantee

Backed Twice Over: Material And Labor

Every install comes with a written workmanship warranty covering our labor specifically, separate from whatever the shingle or metal manufacturer covers on materials.

Warranty terms get explained in plain language during the estimate, not buried in a document nobody reads, and covered repairs get honored without an argument over technicalities.

Term length varies by material, standing-seam metal runs far longer than a standard shingle warranty, and your estimator will lay out exactly what applies to your job.

We also handle registering the manufacturer's material warranty in your name, which matters if a claim ever needs to be filed years down the road or transferred to a new owner.

Where We Work

Dispatch Zones Covering Union And The Surrounding Zips

Because dispatch is staged in and around Union, a crew is rarely more than a short drive from any address we quote in Union, SC.

Jobs get tracked by neighborhood, not just city name, so if one side of Union takes a harder hit in a storm, crews can shift there within hours instead of waiting on a call center to reassign work.

We factor in Union's typical wind exposure when recommending fastening patterns and underlayment, not a one-size-fits-all spec sheet copied from another market.

New requests for Union addresses typically get a callback within the hour during business hours, and after-hours emergency calls get routed to whichever crew is closest at that moment.

Both the city of Union and Union County received their names from the old Union Church that stood a short distance from the Monarch Mill. When it was first founded, the city of Union was known as Unionville; later the name was shortened to Union. The county's first white settlers came from Virginia in 1749. Union County's population grew the fastest between 1762 and the start of the Revolutionary War. Settlers built log cabins and cultivated tobacco, flax, corn and wheat. Union was one of the first towns settled in the area and was untouched during the Civil War because the Broad River flooded and turned Sherman’s troops away from the town.

Recent Feedback From Union Roofing Jobs

★★★★★

"Half our roof came apart in a windstorm around midnight and someone actually picked up the phone. Tarp was up before the rain really started coming down."

Tomás V.
★★★★★

"Got quotes from three companies and this was the only crew that walked me through why my attic ventilation mattered, not just the shingle brand."

Grace N.
★★★★★

"Our warehouse reroof got scheduled around shipping hours and the building never leaked overnight, even with the roof half torn off during the day."

Owen P.
★★★★★

"The adjuster actually said the damage photos made the claim easier to process. Whole thing moved faster than I expected going in."

Renee C.
★★★★★

"Maintenance visit found a flashing gap near the chimney before it ever turned into a stain on the ceiling. Worth every penny of the plan."

Harold B.
★★★★★

"Standing-seam metal roof took an extra day for trim work but the finish around the eaves looks custom, not standard issue."

Simone A.
★★★★★

"Called about a soft spot near the chimney and the inspector found the actual cause was a flashing gap, not a shingle problem, saved me from an unnecessary full reroof quote from another company."

Dale W.
★★★★★

Marisol Q.
★★★★★

"Emergency tarp call came in around 3am during a bad storm and the crew was genuinely on-site within two hours. Didn't expect that kind of response that late."

Questions We Hear Often

Frequently Asked Commercial Roofing Questions

How quickly can a Commercial Roofing crew get to Union?▼
Emergency calls jump the queue ahead of routine estimates, so most tarp-and-secure visits happen the same day they're called in.
Is the pricing really upfront, no surprises later?▼
Yes, every job gets a written line-item quote before work starts, and pricing only changes if hidden decking damage turns up mid-tear-off, which we'll show you directly.
What counts as an emergency roofing call?▼
Anything actively letting water into the structure gets priority dispatch, day or night, ahead of scheduled estimates.
Will you work directly with my insurance adjuster?▼
Yes, we're happy to coordinate scheduling with your adjuster and supply a detailed damage report formatted for a claim.
How long does a full residential reroof take?▼
Most single-family tear-offs and reroofs in Union finish in one to two days, weather permitting.
What roofing materials and systems do you install?▼
Our crews carry certifications across asphalt shingle lines, metal systems, and commercial flat-roof membranes like TPO and EPDM.
Is there a warranty on the work itself?▼
We back our own labor with a workmanship guarantee in addition to whatever material coverage the manufacturer provides.
Do you offer any kind of financing?▼
We work with a few financing partners so larger projects can be split into manageable monthly payments; ask during your estimate for current options.
How do I know if I need a repair instead of a full replacement?▼
We only recommend full replacement when a targeted repair genuinely won't hold, and we'll explain the reasoning either way.
Are your crews actually licensed and insured in Union?▼
Yes, every crew carries current state licensing, general liability, and workers' comp coverage, with documentation available on request.
Can you match my existing shingles for a partial repair?▼
In most cases yes; if an exact match isn't available due to a discontinued color run, we'll walk through the closest options first.
What happens if you find additional damage once the old roof is off?▼
Any decking replacement beyond the original quote gets shown to you directly and approved before it lands on the final bill.
Do you clean up the property after the job is finished?▼
Yes, crews run a magnetic sweep for stray nails, remove all old material and packaging, and haul away debris before considering the job complete.
Do I need to be home during the roofing work?▼
Being present isn't required during installation itself, though we do ask for access to confirm the scope beforehand and to walk the finished roof together afterward.
What's the difference between a repair and a full tear-off?▼
Repairs are targeted and faster; a tear-off is a complete reset, usually recommended once the existing roof is near the end of its rated life or has widespread damage.
