Roof Flashing

Roof Flashing: What You Need to Know

Roof flashing, also known as weatherproofing metal trim or protective edge flashing, is an essential component in roofing systems designed to prevent water infiltration and direct moisture away from critical areas. Used in conjunction with shingles, tiles, or metal roofing, flashing ensures long-lasting protection against leaks, structural damage, and weather-related wear. Available in various colors, gauges, and styles, roof flashing is a crucial addition to residential and commercial roofing projects.

Types and Uses:

• Drip Edge Flashing: Installed along roof edges to guide water away from the fascia and prevent damage to underlying structures. Ideal for extending roof life and enhancing drainage efficiency.
• Roll Flashing: A flexible, continuous metal sheet that provides seamless protection along valleys, ridges, and transitions. It is widely used for custom installations and long-span coverage.
• Step Flashing: Designed for use along chimneys, walls, and dormers, step flashing consists of small, overlapping metal sections that integrate with shingles to create a watertight barrier.
• Transition Flashing: A specialized flashing used where roofing materials meet at different slopes or surfaces, ensuring proper water diversion in complex roofing designs.
• Vent Pipe Flashing: Engineered to seal around roof penetrations such as plumbing vents, exhaust pipes, and HVAC ducting, preventing leaks at critical entry points.

Gauge Options:

• 23-Gauge: A lightweight yet durable option, best suited for small residential applications and non-structural waterproofing.
• 24-Gauge: Slightly thicker for improved strength, commonly used for standard roof flashing installations requiring added rigidity.
• 26-Gauge: A popular balance between flexibility and durability, ideal for general-purpose flashing, step flashing, and drip edges.
• 28-Gauge: A versatile and widely used thickness, providing cost-effective protection while maintaining ease of installation.
• 30-Gauge: A heavier-duty option that offers enhanced strength and longevity for demanding roofing applications.
• 32-Gauge: The thickest and most robust gauge, designed for commercial and industrial roofing where maximum durability is required.
