Chimney Chase Covers

At the top of a masonry chimney, you’ll see a crown that’s protecting the flue from the elements, directing water and snow away. In a factory-built chimney system, a chase cover performs a similar function. While a crown is generally built out of mortar or concrete, a chase cover will be constructed with metal — often galvanized metal, stainless steel or copper.

Since the chase cover is protecting your system from water — its worst, most tenacious enemy — it’s important for it to be doing its job adequately. An early indication that that isn’t happening: rust streaks.

Galvanized metal chase covers are commonly chosen because the material tends to be affordable, but the durability can vary. We sometimes see galvanized metal chase covers needing to be repaired or replaced in as few as five years. If you see rust streaking down the chase cover, call Blue Ridge Chimney Services — that’s a sign that water is getting into your system.

A lot of different factors can contribute to a chase cover beginning to fail — if it was installed so that water is able to pool on the surface, that can allow the metal to start corroding; sometimes holes from screws or nails contribute to rust as well. If you have a problem, let us know — Blue Ridge Chimney Services technicians can bring your factory-built chimney back to functioning correctly and safely.

You Have Several Choices When Replacing A Chase Cover

If your galvanized metal chase cover is rusting or corroding, Blue Ridge Chimney Services can replace it with a similar cover — as a rule, a galvanized metal chase cover can work efficiently for five to 15 years, depending on installation and other factors.

Some other materials you might consider:

Copper is a highly durable material, and offers the added benefit of some beautiful aesthetics — many homeowners really love the green/blue patina that develops as copper reacts to the elements.

Stainless Steel
We all know how durable stainless steel is, and its greatest benefit is that it isn’t going to be affected by corrosion or rust the way galvanized metal will be. We recommend stainless steel for a variety of chimney products, from chimney flue liners to chimney caps.

"Thank you. I wish everyone did business the way you do and had a team as wonderful as yours.

Chris (Jr.) and Steven did an amazing job at my cabin. They worked hard and were professional, knowledgable, efficient and, as you promised, very entertaining. I was inthralled by the process and impressed with their skills and willingness to explain it to me as they went along.

The chimney and the new clean-out look great; the new Napoleon even greater. I know I’m going to love it; the hard part is waiting for cool weather to test run it.

I look forward to my annual inspections and the chance to check in with the Guy family."
