Commercial Metal Roof Coating System to Resolve Leaks in Roswell, GA

A commercial property in Roswell, GA was experiencing ongoing water intrusion issues from an aging metal panel roofing system. The property owner sought a cost-effective, minimally disruptive solution that would extend the life of the roof while addressing leaks and improving overall performance. Based on the project proposal, a high-performance roof coating system was selected to restore and protect the structure without a full replacement.

Project At-a-Glance

• Roof Size: ~65 squares (6,500 sq ft)
• Existing Roof Type: Metal panel roofing system
• New System: GAF high-solids silicone roof coating
• Project Duration: 3–5 days
• Location: Roswell, GA

Challenge: Active Leaks and Aging Metal Roofing System

The existing metal roof showed signs of wear, including potential fastener issues, surface rust, and areas vulnerable to water intrusion. As noted in the scope details, leaks had already impacted the building interior, requiring drywall and ceiling tile repairs.

In addition to stopping active leaks, the solution needed to minimize disruption to business operations and avoid the higher cost and downtime associated with a full roof replacement. Coordinating repairs while maintaining daily operations added another layer of complexity.

Solution: High-Performance Silicone Roof Coating Restoration

Rather than replacing the entire roofing system, a restoration approach using a GAF silicone coating system was implemented. This solution provided a seamless, waterproof membrane over the existing metal panels while reinforcing vulnerable areas.

Key steps included:

• Comprehensive roof preparation, including pressure washing at 2500 PSI to remove contaminants
• Securing and repairing metal panels, including tightening or replacing loose fasteners
• Treating rusted areas with a rust-inhibiting solution to prevent further corrosion
• Applying flashing-grade silicone mastic at penetrations, seams, and transitions
• Installing a single-layer GAF high-solids silicone coating across the entire roof surface
• Ensuring proper termination at coping details for full system integrity
• Completing minor interior repairs caused by previous water intrusion

This approach restored the roof’s waterproofing capabilities while preserving the existing structure.

Result: Extended Roof Life and Reliable Leak Protection

The completed roofing system delivered immediate protection against water intrusion while extending the service life of the existing metal roof. The seamless silicone membrane improved drainage performance and eliminated vulnerable points where leaks previously occurred.

Beyond functional improvements, the reflective properties of the coating contribute to better energy efficiency, helping reduce heat absorption and supporting long-term cost savings. The property owner gained renewed confidence in the building’s protection, along with the peace of mind that comes from a fully restored roofing system.

Trust & Proof: Certified Installation with Strong Warranty Coverage

This project was backed by both manufacturer and contractor assurances. The installed system includes a GAF 10-year Liquid Applied Emerald Pledge Limited Warranty along with a 2-year workmanship warranty.

The project was completed under the supervision of an OSHA-certified superintendent, ensuring safety and quality throughout the process. As highlighted in the proposal materials, the contractor holds multiple industry certifications, including GAF Coatings Pro and other major manufacturer recognitions, reinforcing the reliability and expertise behind the installation.
