Why Good Chimney Flashing is Important

Every chimney component is significant, but chimney professionals are often asked why good flashing is important. The subject comes up frequently because chimney flashing is like the idiom “the squeaky wheel gets the grease.” In other words, those with many problems are more likely to get the utmost attention. At A1 Chimney Specialist, our Certified Chimney Professionals (CCPs) have seen plenty to help explain why good chimney flashing is essential. We can also fix that troublesome issue that most often initiates calls for chimney flashing repair.

What is Chimney Flashing?

Chimney flashing isn’t a topic that comes up in everyday life. So, if a chimney technician has inspected your chimney and discovered that chimney flashing repair is needed, you may not know, at first, what they are referring to. Chimney flashing is the metal portion of the chimney. Its primary purpose is to maintain a watertight seal with the roof. This is not easy.

Why Does Chimney Flashing Frequently Need Repair?

Like all chimney components, chimney flashing is vulnerable to moisture damage and extreme weather. There is, however, a unique problem that stands out as the most common in connection with chimney flashing. It is indisputable that chimney flashing is difficult to install correctly.

So, there are three main types of chimney flashing, as follows:

• Base flashing is installed at the joint between the roof and the chimney, and it is the bottom layer of flashing. Typically, it is embedded in underlayment or roofing cement.
• Step flashing are pieces of L-shaped metal that are layered up the sides of chimneys. Like steps, step flashing is layered one piece on top of another. These are held in place along the chimney bricks and under the shingles.
• Counter flashing is the top layer of chimney flashing. It is embedded into mortar joints, or a groove is cut into the chimney. Counter flashing covers the step flashing, strengthening the barrier against water. To seal off the top of the base flashing, the counter flashing is bent down.

Why is Proper Installation of Chimney Flashing Important?

If the intended watertight seal is not watertight the potential damages can cause devastation to your home and your pocketbook. Because of leaky flashing, entire roofs have had to be replaced. Another effect of leaky flashing is that the masonry underneath experiences moisture intrusion. This can result in the need for a partial or complete chimney rebuild.

Choose Durable Material for Chimney Flashing

One way to avoid problems with chimney flashing is to make sure it has been built with durable materials. Copper and steel are the best choices because they are rust-resistant. Aluminum flashing is prone to rust and is often associated with roof damage. But, in the end, the installation counts most toward avoiding chimney repairs due to flashing damage.
