FAQ: What’s involved in a full roof replacement for commercial buildings?

When Is a Full Roof Replacement Necessary?

You might need a full replacement if your roof has:

• Ongoing leaks or widespread water intrusion

• Storm or hail damage that’s beyond repair

• Wet or deteriorated insulation

• Reached the end of its lifespan (15–30 years depending on system)

• Failed multiple patch repairs or coatings

We always start with a detailed inspection so you can make an informed decision.

What’s Included in a Full Commercial Roof Replacement?

1. Initial Assessment & Proposal

We inspect your entire roof and provide:

• A condition report with photos

• System recommendations (TPO, EPDM, metal, etc.)

• Project timeline and transparent pricing

• Permit and code upgrade details

You’ll know exactly what you’re getting—no vague estimates.

2. Permits & Scheduling

We handle:

• City of Gainesville permitting

• Notice to tenants or building occupants (if needed)

• Scheduling to reduce disruption to business operations

• Safety planning and crew staging

3. Tear-Off of the Existing Roof

We remove the existing roof system down to the deck, unless the structure allows for a code-compliant recover.

• Debris is safely contained and hauled away daily

• We inspect the deck for rot, rust, or damage

• Any required repairs are made before the new system is installed

4. Substrate Prep & Insulation

We install or upgrade insulation to meet current Georgia energy code (R-values) and improve building performance.

• Tapered insulation may be used to correct ponding water issues

• Mechanical or adhesive fasteners are used depending on system

5. Installation of New Roofing System

We install the new roofing system—whether you choose:

• TPO or PVC membrane for energy-efficient, watertight protection

• EPDM rubber for proven durability and flexibility

• Modified bitumen for rugged performance

• Standing seam metal roofing for long-term strength

All systems are installed by our in-house commercial crews, never subcontractors.

6. Flashing, Sealing & Penetration Work

We custom-fit all:

• HVAC curbs

• Skylights

• Drains and scuppers

• Wall transitions

• Edge metal systems

Everything is sealed and reinforced to manufacturer specs.

7. Final Walkthrough & Warranty

We complete a final inspection with your team and provide:

• Manufacturer warranty registration

• Our own 5-year workmanship warranty

• Before-and-after photos

• Maintenance recommendations

We stand by our work—and you’ll always know how to reach us.
