Roof flashing is a thin material that roofing contractors install to prevent water from entering your roof’s interior structure (chimneys, roof valleys, or walls).

Good roof flashing should help with this movement while also developing a tight seal that keeps moisture away from your roof and home.
What Is Roof Flashing?
Roof flashing is a thin material, customarily galvanized steel, that roofing contractors utilize to direct water away from critical areas of the roof, wherever the roof plane comes across a vertical surface such as a dormer or a wall. Simply put, it is also known as a weather-resistant barrier. It is typically installed to surround features of your roof, such as skylights, chimneys, and vents. Water should run down to the flashing side and be directed to the shingles instead of finding its way into the roof deck.
Generally, galvanized steel or aluminum is utilized to make roof flashing. The barrier is then put over wall construction and joints. You can easily find it in the pipes, valleys, around skylights, and around chimneys. It stops water from penetrating inside your roof, and in areas like a valley, it collects from two slopes and directs it down to the gutters. However, every area where it is placed works to direct water to your channels.
There are various roof flashing types. The most common types are apron flashing, counter flashing, and step flashing.
- Apron flashing: Also referred to as “continuous flashing” since it acts as an apron. It’s a single, long metal carried down to the roof below. Long pieces of apron flashing will have problems fixing as the home contracts and expands in the changing seasons. If left unattended, it could warp or break and fail to prevent water out. So, the long pieces come with built-in expansion joints so they can move with the home.
- Step roof flashing: Step flashing is primarily utilized against the sides of chimneys and walls. It works by putting a piece of metal under each shingle that is installed right against the side of a wall to prevent water from getting into it.
- Counter flashing: This type of flashing is utilized on chimneys and walls just like step flashing. Unlike step roof flashing, this kind of flashing is sawed into an existing joint, and metal will come on top of the brick.
