In this blog let me familiarize you with flashing. Know more about the metal roofs and tropical climates

The term refers to the thin pieces installed in roofs in order to prevent water from getting inside a structure in the roof. In simple words, it can be called a weather-resistant barrier.


How it Works?

Generally, Aluminum or Galvanized steel is used to make flashing. The barrier is then placed over joints and wall construction. It is common to find it in the valleys, around chimneys, pipes, and around skylights. It prevents water from penetrating your roof and in areas, such as a valley, it collects water from two slopes and directs it down to the gutters. However, in each area where it is placed it works to direct water to the gutters.

Types of Flashing

The type of flashing used depends on the roof it is used for. The main types are:

Valley Flashing

This is useful in moving water from the slopes towards the gutter in the roof.


Chimney Flashing

This goes around the chimney and directs water away from penetrating and flowing down your chimney.  Generally base flashing at the bottom, step  on the sides, and saddle type is placed at the top. There is also cap type that helps to caulked into the chimney thus it prevents water from penetrating behind them.

Continuous Flashing

Continuous type helps to protect a joint that is between a vertical wall and a sloped roof.

Step Flashing

This is made up of a variety of right-angled metal sheets. Thus each section of the right-angled metal sheets overlaps the section beneath it and is caulked underneath siding or skylights. The purpose is to protect dormers and chimneys as well.

Vent Pipe Flashing

To protect the pipes in your home, vent pipe flashing with a cone flange and a flange at the base is used.

Drip Edges

This is installed to prevent water from seeping underneath the rakes and eaves. It is generally placed under the roofing felt.
