Hi-Tech Contracting & Restoration Corp successfully completed a professional flat roof waterproofing NYC project, restoring two rear flat roofs and improving long-term protection against water intrusion. Both roof surfaces were thoroughly cleaned and power-washed to prepare them for the waterproofing system.
Our team sealed all roof edges, seams, and penetrations with Karna-Flex® to reinforce vulnerable areas before applying two complete coats of Gaco® 100% liquid silicone roof coating. The silicone system created a seamless, flexible, and durable waterproof barrier designed to protect the existing flat roofs from moisture and weather exposure.
The project also included power washing the rear extension stucco wall, repairing existing masonry cracks, and applying Thorocoat® waterproofing paint for additional moisture protection. The completed roof and exterior waterproofing project in NYC delivered improved durability, weather resistance, and a clean, refreshed appearance.
