Type F Drip Edge (Gutter Apron): Complete Guide

Type F drip edge, commonly known as gutter apron, is a specialized roof flashing designed to improve water flow directly into gutters. It is widely used in roof replacements, retrofits, and situations where standard drip edge cannot properly bridge the gap between the roof deck and gutter.

Across North America, Type F drip edge is a preferred solution for correcting drainage issues and improving gutter performance. It is especially useful when replacing roofing systems without removing existing gutters.

This guide covers everything you need to know about Type F drip edge, including sizes, materials, applications, installation methods, and when to use it.

What Is Type F Drip Edge (Gutter Apron)

Type F drip edge is a metal flashing profile with an extended lower flange that directs water into the gutter system.

It consists of

A horizontal flange installed under the roofing material
A vertical fascia flange
A long extended lower apron that reaches into or over the gutter

This extended apron is the key feature that differentiates Type F from other drip edge types.
