Damage to chimney liners or flue liners is not readily visible, which makes it one of the reasons why you need to have your chimney inspected every year. In today’s post, local roofing company Right Angle Roofing & Siding shares an overview of what causes damage to chimney liners and how they can be fixed.
Common Causes of Chimney Liner Damage
The chimney liner is the sheath that protects the chimney from heat, corrosion and creosote buildup. Damage to the chimney liner often stems from poor design and construction. Inexperienced chimney builders sometimes use materials that are not intended for use in chimneys, which can result in premature deterioration from heat and other particles released by burning fuel. Cracks in the flue liner can release gases into the walls of the chimney, which can build up and become a fire risk.
Signs of a Damaged Chimney Liner
Unless you or your roofer or chimney professional is looking directly at the chimney liner, you probably will not see the actual damage. However, you may notice bits of broken masonry that fell into the fireplace, which indicates a crumbling chimney liner.
Fixing a Damaged Chimney Liner
It’s important to note that a standard chimney liner is made with tiles. Most of today’s chimneys will not fit a person of any size — let alone a certain red-suited holiday icon — so repairing an extensively damaged chimney liner will require a partial teardown. Repairs are only recommended if the chimney is structurally compromised.
If the chimney liner is pretty much intact, the most practical option is to install a stainless steel chimney liner, also known as a fireplace insert. It’s a long flexible tube that can be installed in most types of chimneys, and protects the entire chimney interior. It’s heat and corrosion-resistant, which provides long-term protection for the chimney itself. Its tubular shape also makes it easy to clean and maintain. Stainless steel chimney liners can also be installed on new chimneys, or if you’re planning on restoring one.
