Our Parapet Wall Flashing Solutions
We focus on the right materials and precise installation methods to protect parapet walls from water damage. Our approach ensures long-lasting seals and quick fixes for any leaks or water intrusion issues.
Flashing Materials and Technologies
We use durable materials like aluminum, galvanized steel, and copper for parapet wall flashing. Each material offers unique benefits, such as resistance to rust and flexibility in harsh weather.
Modern technologies include self-adhering membranes and liquid-applied coatings. These create strong, seamless barriers that prevent water from entering gaps. We select materials based on building needs and climate conditions.
Installation Methods for Flashing
Our installation starts with cleaning parapet surfaces to ensure proper adhesion. We then fasten flashing securely, overlapping joints to direct water away from walls.
Sealing techniques include using high-quality sealants and mechanical fasteners for extra durability. Proper flashing bends and laps are crucial to prevent water migration behind walls.
Addressing Leaks and Water Intrusion
We locate leaks by inspecting seams, joints, and flashing edges closely. Small cracks or gaps are sealed promptly to stop water entry.
If damage is extensive, we replace the affected flashing section entirely. Our goal is to restore full waterproofing quickly to avoid structural damage or mold growth. Regular maintenance checks help us catch issues early.

Our Parapet Wall Capping Services
We focus on providing durable parapet wall capping that protects your building's edges from weather damage. Our solutions include various metal and alternative materials, carefully designed to work well with flat roofing systems for long-lasting performance.
Metal and Alternative Capping Systems
We install parapet wall caps using metals like aluminum, galvanized steel, and copper. These metals resist rust and provide strong protection against rain and wind. We also offer alternative materials such as PVC or composite capping, which are lightweight and require less maintenance.
Our metal capping is custom-fabricated to fit your parapet walls tightly, preventing water from seeping behind the flashing. Alternative systems are valuable when budget or weight is a concern but still provide good protection.
Integration with Flat Roofing Systems
Proper integration between parapet capping and flat roofing prevents leaks and structural damage. We ensure that the capping overlaps correctly with the roofing membrane, creating a tight seal.
We follow industry standards to secure the capping and flashing, providing extra resistance to water infiltration. This integration also accounts for roof movement and temperature changes to avoid cracks or gaps over time.

Frequently Asked Questions
What are common methods for flashing parapet walls on a flat roof?
We use metal flashing, typically aluminum or galvanized steel, which is bent to fit the wall and roof edges. Another method is using membrane flashing, which involves waterproof sheets welded to the roof surface and wrapped up the wall.
How does capping a parapet wall improve the longevity of a flat roof?
Capping shields the top of the parapet wall from rain and moisture. It prevents water from seeping into the wall structure, which often leads to leaks and damage over time.
