Commercial roof flashing is a material, usually metal, used to prevent water from penetrating the junctions or edges in a roof, such as where the roof meets a wall or chimney.

Overview of commercial roof flashing…

• Purpose – Roof flashing diverts water from vulnerable areas to prevent building damage. It creates a waterproof seal between roofing materials and structural elements like walls, chimneys, vents, skylights, and HVAC systems.
• Materials – Commercial roof flashing is made from durable and corrosion-resistant materials like steel, aluminum, copper, PVC, or EPDM. These materials can withstand environmental exposure and protect against water infiltration.
• Types – Commercial roof flashing comes in various types, such as drip edge, step, counter, valley, and vent pipe flashing. Each type addresses specific areas of vulnerability and ensures proper water management.
• Installation – Correct installation of commercial roof flashing is vital to prevent water intrusion. Trained professionals must follow industry guidelines and manufacturer instructions to securely fasten and seamlessly integrate flashing with other roofing components.
• Maintenance – Regular inspection and maintenance of commercial roof flashing is crucial. Check it routinely to ensure it’s functional, repair or replace any issues promptly to prevent leakage, and maintain the roof’s integrity.
