Roof Flashing Guide
Edge metal, valley flashing, dormer, chimney, and kickout flashing shed water away from the connections between roofs, walls, chimneys, and other building assemblies
This collection of articles, animations, and videos identifies the critical flashing areas, illustrates durable details, and shows how to get it done in the real world.
SIZE UP THE JOB

Flashing a wood-framed chimney is like flashing a dormer, except there’s no roof behind it. Without protection, water can leak into the joint and rot your walls to direct uphill water away
A three-foot stick can hold a section of step flashing out of the way while you work the membrane into place.
