Peachtree Corners has one of the densest concentrations of office and flex-industrial buildings in Gwinnett County, and most of that stock is low-slope commercial roofing pushing 15-25 years old. If you’re a property manager or owner in Technology Park or along Peachtree Corners Circle looking for a commercial roofing contractor in Peachtree Corners, GA, the roof decisions you make this year come down to three things: what system is already up there, how much life is left in it, and whether a full tear-off or a targeted repair actually pencils out.
Why Peachtree Corners’ Roofs Age the Way They Do
Most of the office parks and flex buildings around Technology Park went up in the 80s and 90s, and a lot of them are still running their original built-up roofing (BUR) or an early single-ply retrofit over it. Add Georgia’s summer heat cycling and the pop-up storms that roll through Gwinnett every spring and fall, and seams, flashing, and drains take the brunt of it long before the field membrane fails outright.
The buildings that hold up longest are the ones where someone is actually looking at the roof twice a year instead of only after a leak shows up on the ceiling tile. That’s the gap we see most: a roof that could’ve gone another 5-8 years with proper maintenance gets replaced early because nobody caught a failed pitch pan or a clogged drain in time.
A lot of the Technology Park buildings also carry rooftop HVAC units and antenna mounts added well after the original roof went in — every one of those is a penetration. If your building has had equipment added or swapped in the last decade, flag it specifically when you schedule an inspection.
What We Do for Commercial Buildings Here
Integrity CRR is a Georgia-licensed general contractor (GA #GCCO009212) and a service-disabled veteran-owned business. We’re GAF and Mule-Hide certified, and our roof inspections are done to Haag standards, which matters if a claim ever needs to hold up with an insurance adjuster. Roofing we self-perform with our own crews — we don’t broker the roofing scope out to a sub, and the estimate is written in-house. As the GC we also manage every other trade on the job, a principal is on-site for every project, and the subs we bring in are firms with a track record on prior Integrity work. More on the company and its credentials is on our about page.
For Peachtree Corners specifically, that usually means:
- Roof inspections on office, flex, and light-industrial buildings — flagging seam failures, ponding water, and flashing issues before they become interior damage
- TPO and single-ply roof replacement for the office parks that are still running original BUR or an aging retrofit
- Section repairs and re-cover work where the deck and insulation are sound and a full tear-off isn’t justified yet
- Storm damage assessment and restoration after hail or wind events, including documentation for insurance
- Tenant improvement and build-out work when a roof project overlaps with interior renovations for a new or existing tenant
See our commercial roofing services page for the full system breakdown, or general commercial contracting if the roof is one piece of a bigger project.
Why GAF and Mule-Hide Certification Matters
Manufacturer certification is what makes an extended material or system warranty possible. GAF and Mule-Hide both require installers to meet their own training and workmanship standards before they’ll back a roof with anything beyond a basic materials-only warranty. If a roof is going in ahead of a lease renewal or a building sale, ask any contractor bidding the job whether they’re certified to install the warranty they’re quoting — not every installer bidding low-slope work in Gwinnett County is.
Commercial Roof Replacement Cost: General Ranges
These are widely published metro Atlanta and Southeast market ranges, not an Integrity CRR quote — every roof needs an actual measurement and inspection before a number means anything.
| System | Typical Cost Range (per sq. ft.) | Notes |
|---|---|---|
| TPO single-ply | $6 – $9 | Most common replacement choice for flat commercial roofs today |
| Modified bitumen | $7 – $10 | Common re-cover option over older BUR |
| Built-up roofing (BUR) | $6 – $9 | Legacy system, less installed new now |
| Standing seam metal | $9 – $14 | Longer lifespan, higher upfront cost |
| Silicone roof coating / restoration | $2 – $5 | Extends life on a roof that isn’t ready for full replacement, doesn’t fix a failed deck |
What pushes a project to the top of these ranges: multiple layers of tear-off, rotted or wet insulation found under the membrane, a high number of roof penetrations (HVAC curbs, drains, pipe boots), and difficult access for material staging. What keeps it toward the bottom: a single-layer tear-off, a straightforward rectangular roof, and good crane or hoist access. An actual estimate requires walking the roof.
Repair or Replace: How to Think About It
Repair usually makes sense when:
- The roof is under 15 years old and the deck is dry
- Damage is isolated to a specific area (one seam run, one drain, storm damage to a section)
- A recent inspection shows the membrane still has usable life
Replacement usually makes sense when:
- The roof has multiple layers already and is past its rated lifespan
- Moisture has gotten into the insulation in more than one area
- Repairs are becoming a recurring line item every storm season
A Haag-certified inspection is the fastest way to get a straight answer instead of a guess, especially if you’re deciding this ahead of a lease renewal or a budget cycle.
Storm Damage in Gwinnett County: What Actually Happens with a Claim
Gwinnett gets its share of straight-line wind and hail damage every year, and low-slope commercial roofs don’t always show it the way a shingle roof does — a lot of the damage is granule loss, membrane bruising, or flashing separation that isn’t visible from the ground. If you’ve had a recent storm event, storm restoration covers what we look for and how the insurance documentation process works.
Here’s where most claims lose ground: the contractor writes an estimate in a different format than the carrier uses, and it turns into two people arguing over totals instead of comparing line items. We write every roof estimate in Xactimate — the same platform nearly every property insurance carrier uses to price a claim — because our Haag-certified reviewer holds Xactimate certification. That lets us lay our scope beside the adjuster’s estimate line by line and show exactly what’s missing or underpriced, instead of just disputing a bottom-line number.
Once your claim is approved, we guarantee you get the full value of it. Our in-house Xactimate staff writes every item of justified, claimable damage into the scope, including what carriers routinely miss — code-required upgrades, detached structures, and the labor and materials that only surface once the roof is actually opened up. If the approved estimate comes in short, we document the gap and pursue the supplement. This guarantee covers the completeness of the scope we write — the work we control. What the policy actually covers is between you and your carrier; we’re not a public adjuster negotiating or settling the claim on your behalf. We write the scope, document the damage, and submit supplements as your contractor.

Frequently Asked Questions
How long does a TPO roof last on a commercial building in Georgia?
A properly installed TPO system typically runs 20-25 years, though heat cycling and ponding water can shorten that if drainage isn’t maintained. Regular inspections catch seam and flashing issues that shorten the lifespan long before the membrane itself fails.
Can you repair a roof instead of replacing it?
Often, yes — if the deck is dry and the damage is isolated, a section repair or re-cover can add years of life at a fraction of replacement cost. A Haag-certified inspection is the fastest way to know which situation you’re in.
Do you work with property management companies on multiple buildings?
Yes. We handle roofing and general contracting for property managers overseeing multiple commercial buildings across the Peachtree Corners and Gwinnett County area, including staggered inspection and replacement schedules across a portfolio.
What should I do after storm damage to a flat commercial roof?
Get an inspection scheduled before filing or finalizing an insurance claim — flat roof storm damage (granule loss, membrane bruising, flashing separation) often isn’t visible from the ground. Our storm restoration process includes documentation built for the adjuster process.
What’s the difference between TPO, modified bitumen, and BUR?
TPO is a single-ply membrane, heat-welded at the seams, and it’s the most common new installation today because of its cost and reflectivity. Modified bitumen is a reinforced asphalt sheet, often used as a re-cover over an existing BUR roof. Built-up roofing (BUR) is the older multi-layer, gravel-and-asphalt system — still common on older Technology Park buildings but rarely installed new anymore. Which one makes sense for a given building depends on the existing deck, the insulation condition, and the budget.
Do you offer roof coatings instead of a full tear-off?
Yes, where the roof qualifies. A silicone coating or restoration system can add years of life to a roof that isn’t ready for replacement, but it doesn’t fix a failed deck or wet insulation — an inspection has to confirm the roof is a candidate before that’s the right call.
