- Valleys are the low points between two roof slopes.
- Protrusions such as bathroom vents, chimneys and skylights

What are the types of flashing for your roofing system?
No matter where roof flashing is placed, the overall idea of roof flashing remains the same. There are many types of flashing available, each one being ideally suited to a particular application in the wide flashing range.
Here are the eight most popular types of roof flashing for residential roof. Also, some information about what makes them special.
Base flashing protects roof sections that touch a vertical wall junction, such as your chimney. Base flashing is hidden beneath your siding and shingles so it can’t be easily seen.
Counter flashing is the second component of the base flashing. To protect base flashing, it is placed either above or below it.
Step flashing is a method that uses L-shaped flashing pieces to install flashing along the corner of your roof and your sidewall. This flashing is usually only partially visible so homeowners often choose to match or complement their home’s exterior with a different material.
This is also known as apron Flashing. It is a single, long piece that pushes water away from sloped roofs or vertical walls. The flashing then redirects it to a gutter.
Valley flashing uses flashing for the line of the valley where two roof sides meet and form a valley. It directs water away from the valley and down to the roof.
This flashing is also known as diverter flashing. It’s used to direct water into gutters that meet against sidewalls. Instead of letting water run down the sidewall, it directs water into the gutter.
