Why Flashing Is Critical For Your Chimney

As you know, the chimney is not just layer upon layer of brick and mortar. The chimney has many different components. All of which are very important to the functionality and efficiency of the fireplace and chimney. Today, we will talk about the flashing and its crucial role in the chimney.

Before we can talk about why the flashing is so important, we must discuss what it is.

So, What Exactly Is The Chimney Flashing?

The flashing is a sheet of metal; it could be copper, steel, or aluminum. This sheet wraps around the chimney where the chimney meets the roof. The role of the flashing is to create a watertight seal to prevent water from seeping into your home.

Importance of a Chimney Flashing.

• The flashing plays an intricate role in keeping water out of your home. Proper installation and maintenance of the flashing are crucial to maintaining an airtight seal.
•   The flashing also keeps moisture from building up close to the home. Moisture brings mold and mildew.
• Energy efficiency. Without an airtight flashing, drafts can find their way into the home. In the summer and winter, cool or warm air can escape without the proper seal.
• Improves the look of the home. It is like an extra accessory that protects and makes the home look complete.

Different Types of Flashing.

• Step Flashing – The step flashing is an L-shaped metal piece that is layered with other of the same. This is attached to the bricks of a masonry chimney. This type directs water away from the chimney.
• Base Flashing – This type of flashing is used between the roof and the vertical surface (the chimney). This guards against water seepage.
• Counter Flashing. Also, an L-shaped piece of metal. However, this flashing fits over the step flashing. Used as an extra protection against any water or moisture.
• Drip Edge Flashing. A flashing made out of metal. It is installed along the roof’s edge, focusing on the eaves and rakes. This directs water away from the fascia and into the gutters. This flashing prevents water from seeping under the shingles and causing damage.
• Valley Flashing. When your home has two slopes to the roof, a Valley flashing is used. The flashing is installed in the “valley” as this area is vulnerable to water seeping in at these points. Special attention is given to where the slopes join.
