Drip Edge

Drip edge is a strip of angled metal flashing installed along the edges of your roof — at the eaves (where gutters hang) and the rakes (the sloped sides). Its job is simple: direct rainwater outward and into the gutters instead of letting it curl back underneath the shingles.

Without drip edge, water running off the roof can wick backward under the shingles and soak the fascia boards and the edge of the roof deck. Over time that causes wood rot, peeling paint, and in bad cases decay that spreads into the roof structure itself. It also shields the edge of the underlayment from wind-driven rain.

Drip edge is a standard part of a modern roof replacement and is required by many building codes. It comes in different profiles and materials — aluminum and galvanized steel are most common — and it should extend slightly past the fascia with its lower flange sitting behind the gutter.

Why It Matters

If your roof was installed without drip edge, the perimeter is the most vulnerable part of the system. During a roof replacement, confirm drip edge is included — it is inexpensive protection for the entire edge of your roof.

What to Watch For

• Peeling paint or soft, spongy wood on fascia boards
• Water stains on the underside of the eaves
• Shingles curling upward at the roof's edge

A Maryland Note

Maryland's heavy summer downpours and hurricane-season rain test roof edges hard. Rotted fascia from missing or failed drip edge is one of the most common findings on older Maryland homes.
