GD Commercial Roofing started with two crew leads who got tired of watching sales-first outfits quote jobs they'd never personally climb a ladder to check. Every estimator here still walks the roof before pricing it.
Insurance and licensing aren't just filed away somewhere. Crew leads carry documentation on the truck and will hand it over before stepping on your roof.
Our after-hours dispatcher can get a tarp crew rolling before sunrise if an active leak is putting the inside of your home at risk.
Estimators walk the deck in person rather than pricing off a satellite photo, which is the only way to catch a rotted section before it becomes a change order mid-job.
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.
Most roof damage is gradual, not sudden. Catching one of the signs below early is often the difference between a targeted repair and a full replacement bill. None of these checks require climbing onto the roof itself, just a careful look from the ground, the attic, or the gutter line.
A little granule loss is normal wear; a gutter full of dark grit after a rain usually means the protective coating has thinned enough to let UV rays start breaking down the mat underneath. A quick gutter check after any hard rain costs nothing and catches this early.
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.
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.
Decking that gives slightly underfoot, especially near a valley, usually means the plywood underneath has already taken on moisture and started to soften. This one's better left to a trained inspector rather than testing it yourself.
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.
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.
Every category below is handled by our own crews, not a rotating list of subcontractors, which keeps quality consistent from the estimate to the final walkthrough. If a job falls outside these categories, ask anyway, there's a good chance we've handled something similar before.
A tree limb through the decking or wind-torn shingles gets a same-day tarp and a documented plan for the permanent fix once the roof is dry and safe to work. A quick check-in after the initial tarp job makes sure everything's holding before we lock in a date for the permanent repair.
A single-family tear-off and reroof in Columbia usually runs one to two days, with synthetic underlayment, ice-and-water shield at eaves and valleys, and ventilation matched to the new shingle system. We help homeowners choose a shingle line during the estimate, which keeps the crew from standing around waiting on a color pick mid-project.
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.
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.
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. Maintenance clients also move up the priority list during storm season, which matters when every crew in Columbia is suddenly booked solid.
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.
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.
An estimator walks the roof, photographs trouble spots, and checks the attic when possible, since staining up there often tells us more than the shingle surface alone. Most inspections take under an hour.
If rotted decking does show up once the old roof is off, we stop, show you the damage in photos, and get your sign-off before adding anything to the bill. You can take as long as you need to review it before scheduling.
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.
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.
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.
Local staging means a crew is rarely more than a short drive from any job we quote in Columbia. That same local presence means a real person can meet you on-site after the job wraps if a question comes up.
Every technician carries current state licensing plus general liability and workers' comp coverage, on hand and available on request. Documentation gets shown before a contract is signed, not after a question comes up.
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.
Every install comes with a written workmanship warranty covering our labor specifically, separate from whatever the shingle or metal manufacturer covers on materials.
If a covered issue shows up, we come back and fix it at no charge, and we'll explain in plain terms what is and isn't covered before you ever sign anything.
Warranty coverage typically runs anywhere from five to fifty years depending on the material system installed, and we'll spell out the exact term for your specific project before you decide anything.
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.
Because dispatch is staged in and around Columbia, a crew is rarely more than a short drive from any address we quote in Columbia, IL.
Local crews know which Columbia neighborhoods have older decking that needs extra attention and which subdivisions have HOA rules around shingle color and style.
We factor in Columbia'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 Columbia 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.
