Systems we install
- TPO — heat-welded single-ply, the most common new flat roof.
- PVC (Duro-Last) — prefabricated, chemical- and grease-resistant, ideal for restaurants.
- Modified bitumen and EPDM — repairs and replacements on existing systems.
- Metal — standing seam re-roofs for offices and medical buildings.
- Coatings — restore and extend an aging roof without a tear-off, including ASTEC systems from an Authorized Contractor.
Building types we serve
Office and retail, warehouses and light industrial, medical, churches, apartment and condo communities, and restaurants. We work around tenants and operating hours.
Drainage is everything
Most flat roof failures start with ponding water. On replacements we design tapered polyiso insulation to move water to drains and scuppers — and fix the cause, not just the membrane.
Inspection, scope and execution - no surprises
Commercial roofs fail quietly. By the time water shows up on a ceiling tile, it has usually been traveling under the membrane for weeks. Our commercial inspections start on the roof - seams, flashings, penetrations, drains and edge metal - and include core cuts or a moisture survey when we suspect wet insulation, because that single question decides whether a roof can be restored, recovered or has to come off.
You get a written report with photos and a clear recommendation: repair, restore with a coating, recover over the existing roof, or full tear-off. Each option is priced so owners and property managers can plan capital budgets instead of reacting to leaks.
Recover or tear off?
Building codes allow a new roof system to go over an existing one only when the existing roof is dry, structurally sound and there's no more than one existing layer. A recover saves tear-off and disposal costs and keeps the building in operation, but putting a new membrane over wet insulation traps the problem and voids the value of the new roof.
We check before we recommend. When a recover makes sense, it's often the best-value move a building owner can make. When it doesn't, we'll show you why with cores and photos. See TPO, PVC, EPDM, modified bitumen and roof coatings for system details.
Working around occupied buildings
- Phased work so tenants, congregations and customers keep operating.
- Early-morning, after-hours and weekend scheduling when the building needs it.
- Daily dry-in - no section of roof is left open overnight.
- Rooftop unit coordination with your HVAC contractor, and protection of interior spaces below active work.
- One point of contact from proposal to closeout, with photo updates.
Warranties, maintenance and tax considerations
Our TPO roofs are installed with GAF EverGuard 60-mil membrane, backed by a 20-year material warranty and Mosaic's 10-year workmanship warranty. As a Duro-Last Authorized Dealer we also install Duro-Last PVC systems for buildings that need superior chemical and grease resistance, like restaurants.
Ask us about planned maintenance: a twice-a-year inspection with drain and seam checks is the cheapest way to make a commercial roof reach its full life. Under current federal tax law, roofs on nonresidential buildings may also qualify for accelerated depreciation (Section 179) - talk to your accountant about whether it applies to your property.
Frequently asked questions
Do you offer commercial maintenance plans?
Yes — regular inspections and minor repairs catch problems before they become leaks inside your tenant spaces.
Can you recover an existing flat roof instead of tearing it off?
Often, if the existing roof and insulation are dry. We test for moisture before recommending a recover or overlay.
How quickly can you respond to a commercial roof leak in Atlanta?
For active leaks we aim to have someone on site the same day, usually within 4 to 6 hours, to stop the water and protect the interior. Permanent repairs are scheduled once the roof is dry.
Do you work after hours or on weekends for occupied buildings?
Yes. We regularly schedule early mornings, evenings and weekends for churches, offices, restaurants and retail so the building can keep running.
Do you pull the permits?
Yes. We handle the building permit wherever the city or county requires one and schedule any required inspections.
Are you licensed and insured?
Yes. We'll send a certificate of insurance to you or your property manager on request before work starts.
What does a commercial roof replacement cost?
Commercial pricing depends on the square footage, the system, insulation thickness and tapering, drainage changes, edge metal and access. We price every option in writing after the inspection so you can compare repair, restoration, recover and replacement side by side.
