Our metal roof waterproofing process begins with a thorough inspection and cleaning of the entire roof surface to remove rust, dirt, and loose materials before any treatment. We then apply a high-performance rust-inhibiting primer followed by a flexible, UV-resistant waterproofing coating that bonds firmly to all metal surfaces. Special attention is given to seams, overlaps, and screw points — the most common areas where metal roofs develop leaks and corrosion over time. The final coating provides a tough, weather-resistant barrier that extends the life of your metal roof by many years and reduces maintenance costs significantly.
