Here are some causes of chimney rust.
While brick chimneys are sturdy structures that endure crackling fires in the fireplace and various weather conditions, they are not indestructible. The chimney comprises several elements, some of which are made of metal. These components, such as the damper, chimney cap, and flashing, are susceptible to rusting. Whatever the cause of rust, it is essential to address the problem. Here are some reasons why your chimney could be rusting. Read on to learn more.
Rusted Chimney Cap
If your chimney cap is not made with stainless steel or copper material, rust will eventually flow from an aging cap. The reddish streaks of rust are a sign that your chimney cap needs to be replaced. The rust can contribute to the deterioration of your masonry structure and should be removed. Unless replaced, the rust will continue to eat through the metal element allowing water to leak in the chimney, causing extensive damage.
Rusted Chimney Flashing
The chimney flashing is the metal base designed to create a watertight seal between your roof and the chimney. Since the flashing is made of metal, it is also prone to rust. Just a single rusted nail could allow water to leak through your roof, causing significant damage. It is highly recommended to have your chimney inspected annually by qualified professionals, and inspections include a thorough examination of chimney flashing and any indications of rust.
Rusted Firebox
A damaged firebox creates dangers like those associated with a failing chimney flue. Rust from the chimney cap or liner can also affect the firebox. Additionally, if water damage has resulted in a leaky chimney, the chimney damper could develop rust and impact the functionality of your firebox. It is essential to make repairs before you use the fireplace again.
Removing Rust Stains
Removing rust stains from your chimney is crucial because the oxidized material can contribute to masonry deterioration. Rust removal is complicated, however. For instance, using a power washer to remove rust is not recommended because the spray can easily damage bricks and destroy mortar. It is best to contact a professional chimney sweep to remove all the rust from your chimney properly.
Preventing Chimney Rust
The best way to prevent chimney rust is to minimize moisture exposure. It is a good idea to inspect and clean your chimney annually and make necessary repairs to protect against water seepage.
