Counter Flashing Installation on Brick Wall – Waterproofing Wall Leak Repair Water intrusion where a roof meets a brick wall is one of the most common causes of persistent leaks in both residential and commercial buildings. When counter flashing is missing, improperly installed, or deteriorated, water can penetrate behind the masonry, leading to interior wall damage, wood rot, mold growth, and structural deterioration. Our counter flashing installation process is designed to permanently waterproof roof-to-brick-wall transitions and stop active wall leaks. We begin with a thorough leak inspection to identify failed flashing, cracked mortar joints, deteriorated sealants, or improper step flashing integration. For a proper repair, we cut a clean reglet into the brick mortar joint to install new metal counter flashing. This method ensures the flashing is embedded directly into the masonry rather than surface-mounted, creating a secure and long-lasting waterproof seal. High-grade sealant is then applied within the reglet to lock the flashing into place and prevent water penetration. Where applicable, we inspect and replace the underlying step flashing system to ensure proper layering. The counter flashing is fabricated to overlap the base flashing correctly, allowing water to shed away from the wall and roof junction. All components are custom fabricated sheet metal flashings designed for proper slope, coverage, and durability. This repair method is ideal for: • Roof-to-brick wall transitions • Chimney flashing repairs • Parapet wall waterproofing • Commercial masonry wall leak repairs • Residential brick veneer leak issues A professionally installed counter flashing system prevents recurring leaks, protects interior finishes, and extends the life of both the roofing and masonry systems. If your property is experiencing water intrusion along a brick wall or chimney area, addressing the flashing system is critical to stopping the leak at its source.
