Commercial Roof Replacement – GAF 50 Mil TPO System | 20-Year NDL Warranty | Spray Foam Failure Recovery
February 2026
Commercial Roof Replacement – GAF 50 Mil TPO System | 20-Year NDL Warranty | Spray Foam Failure Recovery Gold Key Roofing was selected to replace a failed spray polyurethane foam (SPF) roofing system on an existing commercial building after only three years of service. The owner had originally been persuaded to install a spray foam roof, but within a short period the system developed dozens of active leaks. Unfortunately, the original installer was no longer available, leaving the property owner with significant water intrusion and no accountable warranty support. After receiving over nine roofing proposals, the owner chose Gold Key Roofing because we provided practical, long-term solutions — not temporary patches. Our evaluation focused on system integrity, manufacturer backing, and verifiable warranty protection. We removed the compromised foam roofing system and installed a GAF 50 Mil TPO single-ply membrane, fully heat-welded at all seams to create a monolithic waterproof barrier. Heat-welded TPO systems provide superior seam strength, long-term flexibility, and dependable performance for commercial low-slope applications. The project was completed with a 20-Year NDL (No Dollar Limit) manufacturer warranty, covering leaks and product defects. Following installation, The Walker Group conducted an independent inspection and formally approved the system, validating the workmanship and authorizing the manufacturer-backed warranty for the owner’s protection. After experiencing a failed roof and unsupported warranty, the owner was understandably cautious. This project delivered not only a durable roofing system but also something more important — accountability. Gold Key Roofing has been standing behind its work for over 50 years, providing commercial clients with real manufacturer warranties and long-term service support. Project Highlights: Removal of failed spray foam roofing system Installation of GAF 50 Mil TPO membrane Fully heat-welded seams 20-Year NDL manufacturer warranty Third-party inspection and approval by The Walker Group Long-term commercial roofing solution Gold Key Roofing specializes in correcting failed roofing systems, commercial TPO installations, manufacturer-backed NDL warranties, and long-term roofing solutions throughout Central Florida.
