Flashing - we likely hear people talk about it, know that it is important, and know that if we don't have it then we have an issue.
Flashing is typically a thin sheet/strip of water-resistant material (usually metal or plastic) that's installed at key areas of your home to keep water out. Examples of this are roof intersections, penetrations, valleys, and more. It is also used around things like windows and doors, where roofs meet your home's walls, in key areas around stucco, and along foundation walls. All of this so that it can do one essential job: direct water away from the home.
Flashing guides water away from the home in critical areas. Without proper flashing, our homes would be lost to the elements. Knowing this, when hiring a contractor to build or repair a home, be sure to ask about their flashing methods and what materials they will use. Also, be sure to ask your home inspector about the condition of your home's flashing. Because while not always seen, flashing is one of the big "Heros" of your home!
