The different shapes, or profiles, that drip edges come in are named after letters. This can be confusing because the letter type doesn’t always describe the shape very well, so another letter is often used to identify the style.
A Type C drip edge has the simplest profile—it’s an L-shaped piece of metal bent at a 90-degree angle, sometimes with an additional flange or flare on the bottom edge. Because of its shape, it’s also called an L-style drip edge and is mostly recommended for low-profile roofs. This type usually costs between $0.30 and $1.00 per linear foot.
Type D is also called T-style because its profile is shaped like the letter T. The top of the T extends further out over the gutter than the L-style edge, making a Type D drip edge more effective at directing water away from a roof. It’s a little more expensive at $1.00–$1.50 per linear foot, but the Asphalt Roofing Manufacturers Association recommends this type of drip edge for most residential roofs.
Type F drip edges are similar to Type D, but they have a longer leading edge, which makes them easier to secure over existing shingles. If you need to install a drip edge on a finished roof, Type F is usually what you need. It’s priced similarly to Type C at $0.30–$1.00 per linear foot.
The following roof flashing types aren’t technically drip edges, but they serve a very similar function.
Protects walls underneath flat or very low-profile roofs.
Similar to Type C drip edges but larger with a wider angle, overhanging farther into the gutters.
Runs along a roof’s gabled edges (the angled edges without gutters) and can be T-style or L-style. Although precipitation doesn’t typically run directly off these edges, the rake edge ensures any water that reaches it gets directed away from the frieze boards on the house’s side.
