Apron Flashing

Apron Flashing protects the lower edge where a vertical wall or chimney meets a sloped roof. It sits at the base of these intersections and channels water safely over the roof’s surface. Without it, rainwater can seep into gaps, leading to leaks, rot, or structural damage.

Because these areas collect runoff, apron flashing plays a crucial role in roof performance. It catches water coming down walls or chimneys and directs it onto the roofing panels below. This keeps vulnerable seams dry, even during storms or snowmelt.

We fabricate Apron Flashings from .032, .040, or .050 aluminum, 24ga or 26ga steel, and 16 oz. copper. These materials hold up against harsh weather, wind, and daily temperature changes. For added protection, we finish all metal in Kynar 500® coatings, which resist chalking, UV damage, and corrosion. This ensures color consistency across all roof trim.

Each flashing is custom-formed to suit the roof’s slope and the panel’s profile. You can also request features like hemmed edges, stiffening ribs, or welded corners, depending on your project needs.

Key Features:

• Directs water away from vertical-to-slope transitions

• Helps protect chimneys, walls, and skylight curbs

• Made from durable aluminum, steel, or copper

• Kynar 500® finish ensures long-term performance

• Custom-formed to fit roof slope and panel type

• Optional hems or bends add strength and ease of installation

Commonly Used With:

• Step Flashing and Counter Flashing – For complete chimney and dormer detailing

• Chimney Chase Covers – To seal upper and lower transitions

• Standing Seam Panels – For a clean and integrated termination

• Wall Cladding or Siding – To provide full envelope protection

Apron Flashing keeps moisture out, adds visual continuity, and reinforces critical roof-to-wall connections.
