Drip edge is a low-cost roof flashing installed at eaves and rakes to channel runoff away from the roof and building. Made from aluminum, galvanized or stainless steel, or copper, it protects fascia and roof deck from water damage, helps shingles lay flat at the edge, and is commonly required by code for asphalt-shingle roofs. Install per manufacturer instructions and local code or hire a licensed roofer.

What a drip edge is

A drip edge is a narrow metal or rigid plastic flashing installed at the eaves and rakes (the sloped edges) of a roof. Its profile directs rainwater off the roof edge and away from the underlying roof deck, fascia, and wall cladding so water does not run back against the structure.

Common materials

Manufacturers make drip edge from aluminum, galvanized or stainless steel, and copper. Rigid PVC (vinyl) versions exist but are less common for long-term use. Choose a noncorroding finish and a gauge appropriate for your climate and roof type.

Why you should use one

A properly installed drip edge protects roof edges, fascia, and soffits from water damage. It helps shingles lie flat at the edge, channels runoff into gutters, and reduces the chance of water working behind roofing underlayment or siding. Many building codes and modern roofing best practices require drip edge on asphalt-shingle roofs to reduce edge leak risk.

Basic installation overview

  1. Inspect and prepare the roof edge. Remove debris and fasten any loose fascia or edge boards. Replace rotten material.
  1. Position the drip edge along the eaves and secure it with corrosion-resistant roofing fasteners. Common practice uses nails long enough to penetrate the underlying framing, but specific fastener sizes and spacing vary by product and code.
  1. At rakes (sloped edges), install drip edge where the manufacturer and local code indicate - details differ by roof system. Overlap pieces at butt joints and bend or miter corners for a clean fit.
  1. Install underlayment, shingles, and flashing per manufacturer instructions. For best results follow the drip edge maker's guidance and local building code requirements.
If you are not comfortable with roof work or local code nuances, hire a licensed roofing contractor. Proper flashing and fastening are important to performance and warranty compliance.

Benefits at a glance

  • Directs water away from roof deck and walls
  • Prevents fascia and soffit rot
  • Ensures shingles terminate cleanly at the edge
  • Reduces risk of leaks and ice-dam damage when paired with correct underlayment

Where to buy

You can find drip edge at local building supply stores, roofing suppliers, and major home improvement retailers. Buy from reputable manufacturers or dealers and match the metal type and finish to your roof and gutter system.

Final note

A simple strip of flashing adds disproportionate protection to your roof edge. When in doubt, consult local code requirements and a professional roofer to choose the correct profile, material, and installation method for your home.

FAQs about Drip Edge

Do I need a drip edge on my roof?
Yes for most modern roofs. Drip edge protects the roof deck and fascia from water and is commonly required by building codes for asphalt-shingle roofs. It's a small investment that reduces edge leakage risk.
What material should I choose?
Aluminum and galvanized or stainless steel are common and durable choices. Copper is long-lasting and used for high-end roofs. PVC exists but may not be ideal for long-term exposure - match material and finish to your roof and gutters.
Can I install drip edge myself?
A competent DIYer can install drip edge if comfortable working on a roof and following manufacturer and local code guidance. Otherwise hire a licensed roofer - proper fastening and flashing detail matter for long-term performance.
How long does drip edge last?
Lifespan depends on material and environment. Aluminum and galvanized steel typically last decades; stainless steel and copper last longer. Regular roof inspections will reveal any corrosion or loose sections.
Will a drip edge fix leaking gutters?
A drip edge directs roof runoff into gutters but won't fix gutter issues such as clogs, improper slope, or damaged seams. Both gutter maintenance and proper drip-edge installation are important for full edge protection.
