What is Roof Flashing, and how does a Residential Roofer in Iowa City install it?


The textbook definition of flashing is “pieces of sheet metal or the like used to cover and protect certain joints and angles, as where a roof comes in contact with a wall or chimney, especially against leakage.” Flashing is fundamental in preventing water from leaking through a roof, specifically in areas vulnerable to water penetration.



A roofing company in Iowa City will typically install flashing around the base of chimneys, skylights, roof valleys, and any place where you put a hole in the roof to install a feature.

4 Types of Flashing According to Residential Roofer in Iowa City

There are many different kinds of flashing that a roofing company in Iowa City wants homeowners to know about. The following are just a few of the most common.


  • Chimney Flashing – As you can assume, chimney flashing is installed around the base of a chimney where it meets the roof. This kind of flashing consists of two metal panels – base flashing and counter flashing. Installing chimney flashing is fairly challenging, which is why you must enlist a top residential roofer in Iowa City to do it for you.
  • Continuous Flashing – The role of continuous flashing is to protect the joints that are between a vertical wall and a sloped roof.
  • Drip Edge – Drip edge helps prevent water from finding its way along the rakes and eaves’ edges.
  • Step Flashing – This kind of flashing is installed where the roof meets dormers’ sidewalls, skylights, and chimneys. It is installed in a way where pieces of flashing overlap one another.
