The answer to 'types of drip edge' is that there are several common types of drip edge used in roofing. Drip edge is a metal flashing installed along the eaves and rakes of a roof to help direct water away from the fascia and siding. The most common types are aluminum, galvanized steel, and vinyl drip edge.
Aluminum drip edge is a popular choice as it is lightweight, corrosion-resistant, and easy to install. Galvanized steel drip edge is also a durable option, though it may be heavier and more challenging to work with. Vinyl drip edge is a more affordable alternative that can be painted to match the roof color.
