Type D is also called T-style because its profile is shaped like the letter T. This type usually costs between $0.30 and $1.00 per linear foot. Because of its shape, it’s also called an L-style drip edge and is mostly recommended for low-profile roofs. Type C (L-Style)Ī 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. 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. The different shapes, or profiles, that drip edges come in are named after letters. * Article cost data in this article was sourced from Angi. Instead, they’re typically installed over windows or doors. ![]() There are also plastic, fiberglass, and vinyl drip edges, though these aren’t durable enough for use on a roof. But, it’s also highly durable and creates a unique appearance. Copper Drip EdgesĬopper is the most expensive metal used to create drip edges, usually priced at $3.50–$7.50 per linear foot. Note that all types of steel roof flashing must be galvanized to prevent rust. Galvanized steel costs about the same as aluminum, but it also holds up better against strong wind. Aluminum Drip EdgesĪluminum is lightweight and relatively inexpensive at about 30 cents to $1 per linear foot.* It’s not as strong as other metals, but it resists corrosion and is available in an enamel finish in a variety of colors to match your roof. We’ve outlined the different metal types below. Roof drip edges are most commonly made of metal since it’s a highly durable material. Finally, sealing the gap between the roof edge and the fascia can keep insects and other pests from making their homes in these tight crevices. Proper water flow is also necessary in cold climates to prevent the formation of ice dams, which put extra stress on a roof and can weaken the structure. Strong winds can potentially push precipitation up under the lowest row of shingles, but a drip edge prevents wind-driven rain from loosening or corroding these shingles. In a worst-case scenario, water can get into your attic or walls, causing further damage regardless of whether you have a shingle, tile, or metal roof.Ī drip edge also offers some protection from severe weather. ![]() Without a drip edge, moisture from rain and other precipitation can drip behind the gutters and run down the fascia into the soffit boards, causing water damage to wooden structures and roofing underlayments. A drip edge’s primary purpose is to prevent moisture from getting underneath the row of shingles closest to the roof’s eaves, and to direct water away from the fascia and into the gutter.
