Drip Edge Material Types
Drip edges are made of various plastics and metals, which are both acceptable under most building codes so long as the metals are corrosion-resistant or galvanized.
- Aluminum: A common material for drip edges, aluminum isnt as strong as steel. It doesnt corrode and is often sold in colors that match the rest of the home exactly.
- Galvanized steel: Drip edges are designed to be in contact with water so, if they are made of steel, they need to be galvanized to prevent rust. Minimum 24-gauge steel is preferable so that the drip edge can withstand strong winds.
- Copper: Copper is a sturdy metal that gives a roof a unique look. When used as a drip edge, it should be a minimum of 0.69 mm or 20 ounces.
While plastic, vinyl and fiberglass drip edges may also be available in your area, these materials are best suited for use in nonroofing applications, such as above doors and windows.

In addition, cut an eight inch strip of Sharkskin Ultra SA underlayment and install it over the eave flashing as shown in the picture and video. Once this is done you will have underlayment both underneath and over the eave trim.

How Edge Metal Is Installed
Wood blocking, typically a combination of 2×4s, 2×6s, or 2×8s, is installed directly on the roof deck at the edge of the roof .
The wood blocking as installed will match the exact height of the roof system at the perimeter and will be wide enough to carry the horizontal flange of the edge metal. The wood blocking is fastened or anchored to the roof deck or top of the parapet wall.
Pressure-treated lumber was used for years as wood blocking on roofs, but this is no longer recommended by roofing industry authorities. The chemicals in treated wood tend to corrode many types of fasteners. Untreated lumber is now recommended for wood blocking.
The edge of the roof membrane runs over the wood blocking and extends down the exterior of the wall for a few inches.
Typically a hidden metal cleat is then installed on top of the roof membrane. The fasteners for the cleat go through the roof membrane and into the wood blocking. This allows the cleat to clamp the edge of the roof membrane in place.
The visible part of the edge metal is a separate piece that is clipped onto the cleat. The cleat is what actually secures the perimeter edge of the roof.
