Commercial TPO Roof Replacement in Bonaire, GA

A national bank branch in Bonaire, GA required a durable, energy-efficient replacement for its aging low-slope roof. The owner selected a fully adhered Johns Manville (JM) TPO roofing system with a 20-year manufacturer No Dollar Limit (NDL) warranty to ensure long-term performance with minimal disruption to daily operations.

Project At-a-Glance

• Roof size: approximately 30 squares (~3,000 sq ft)
• Membrane: 60-mil Johns Manville TPO (fully adhered)
• Insulation: Johns Manville ENRGY 3 polyiso (flat and tapered for positive drainage)
• Perimeter metal: PAC-CLAD prefinished coping, color-matched
• Roof access: Bilco S-50TB roof hatch (approved as meeting design intent)
• Warranty: 20-year manufacturer NDL
• Location: Bonaire, GA

Challenge: Upgrade performance and appearance without disrupting a live branch

The project required careful staging, safety controls, and coordination to protect customers and staff while work progressed. The roof needed improved drainage, robust edge protection, and secure access, all within a cohesive manufacturer system to support the NDL warranty and maintain the center’s clean architectural lines in Bonaire, GA.

Solution: Complete Johns Manville TPO system with tapered insulation and architect-approved components

We installed a fully adhered 60-mil JM TPO membrane over a JM ENRGY 3 flat-and-tapered polyiso package to build thermal performance and create positive drainage. PAC-CLAD coping provided a crisp, durable perimeter finish, and the Bilco hatch delivered secure, code-compliant roof access—all aligned with manufacturer requirements for the 20-year NDL warranty and commercial roofing best practices.

Key Steps

• Established safety zones, protected entries and sidewalks, and scheduled noisy work during off-hours.
• Installed flat and tapered JM ENRGY 3 polyiso to achieve slope-to-drain and improve R-value.
• Adhered 60-mil JM TPO membrane and hot-air welded seams per manufacturer requirements.
• Used JM-approved fasteners and plates where specified for system compatibility.
• Set Bilco S-50TB roof hatch for durable, secure access without compromising warranty pathways.
• Finished with PAC-CLAD prefinished coping for long-term edge protection and clean lines.
• Completed manufacturer-aligned quality checks supporting issuance of the 20-year NDL warranty.

Result: Watertight protection, better drainage, and a clean architectural finish—completed November 2025

The branch received an energy-efficient, UV-resistant TPO roofing installation that improves drainage and strengthens weather resistance. The refined perimeter detailing enhances curb appeal for customers and neighboring tenants, and the 20-year manufacturer NDL warranty provides long-term peace of mind for the property owner in Bonaire, GA.
