The importance of chimney flashing and how it protects homes from water damage

What is chimney flashing

Chimney flashing plays a critical role in protecting the area around the junction of the roof and chimney from water damage. Installed correctly, it creates a nearly impenetrable barrier to keep water on the outside of the joint, ensuring years of structural integrity and keeping your roof and home weatherproofed.

However, when chimney flashings become damaged, water can penetrate the joint between the roof and chimney and cause significant damage if not treated quickly. In this short article, we’ll discuss what chimney flashings are, how they keep roofs dry, and the importance of getting them repaired if they become worn down.

What are Chimney Flashings?

Chimney flashings are typically made of metal or rubber and are installed around the point where the chimney meets the roof. They can come in a variety of different shapes and sizes, but most commonly have an L-shaped design. This special shape helps to seal both parts of the joint together, creating a tight barrier that keeps out rain and other moisture.

How Chimney Flashings Keep Roofs Dry

The primary purpose of chimney flashings are to keep moisture from entering the joint between the roof and chimney. By sealing this joint, the flashings keep water out, preventing damage to both the roof and chimney.

While chimney flashings can be made of metal or rubber, metal is typically the most durable option and is primarily used to protect roofs exposed to large amounts of rain and other weather elements. The metal not only provides a barrier, but also helps to redirect the water away from the exposed areas.

What Happens When Chimney Flashings Are Damaged

Chimney flashings are designed to last for many years, but over time, they can become worn down due to severe weather conditions or the natural aging process. If the flashings are not replaced in a timely manner, water can enter the joint and cause serious damage to the roof and chimney such as degrade waterproofing, discolouration, and rot.

In addition, damage to the chimney and roofs can put your home at risk of mould, mildew, and other structural damage depending on the extent of the water penetration. To avoid such risks, it’s important to assess and repair any existing chimney flashings before the damage becomes more extensive.
