Wall flashings are a critical yet often overlooked component of any roofing system. These metal strips or membranes are installed where the roof intersects vertical surfaces (like walls, dormers, and chimneys) to prevent water infiltration. When flashings fail—whether due to age, storm damage, poor installation, or corrosion—it can lead to thousands of dollars in water damage, mold, and structural decay.
As Asheville, NC experiences both high humidity and seasonal storms, wall flashing failure is a significant risk to homeowners. That’s why understanding the cost to replace wall flashings is not just about budgeting—it’s about protecting your most valuable investment.

What Affects the Cost to Replace Wall Flashings?

If old flashing is rusted, buried under layers, or attached with roofing cement, expect removal costs between $100–$300.
