Flashing & Water Intrusion Protection
PGH Roofing provides expert flashing repair, replacement, and water intrusion protection for homeowners throughout the greater Pittsburgh area. Flashing is the metal barrier installed at every joint, transition, and penetration on the roof — chimneys, walls, valleys, vents, pipes, and skylights. When flashing fails, water enters the roof system and causes damage that can go undetected for months. PGH Roofing’s whole-system approach treats flashing as one of the most critical components of every roofing project.
