What is Longitudinal Flashing?
Longitudinal flashing is a waterproof barrier that directs water away from critical areas in a building, particularly where the roof meets vertical surfaces like walls or chimneys. It serves as a protective measure against leaks and water damage, which can lead to costly repairs and structural issues.

Why is Flashing Important?
Prevents Water Damage: Properly installed flashing prevents water from seeping into walls and roofs, which can cause mold, rot, and structural damage.
Enhances Energy Efficiency: By preventing leaks, flashing helps maintain indoor temperatures, reducing energy costs.
Extends Lifespan of Roofing Materials: Flashing acts as a shield for roofing materials, reducing wear and tear from water exposure.
The Advantages of 0.47mm Thickness
Durability and Strength
At 0.47mm, this thickness of longitudinal flashing strikes an excellent balance between flexibility and strength. It’s thick enough to withstand harsh weather conditions while remaining pliable enough for easy installation. This thickness is particularly beneficial in areas subject to high winds or heavy rain.

Corrosion Resistance
Made from materials such as aluminum or galvanized steel, 0.47mm flashing is resistant to corrosion, which is vital for longevity. It can withstand the elements—whether it’s rain, snow, or exposure to intense sunlight—making it a reliable choice for any roofing project.
