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.

"I thank you all for a most excellent job well done. An amazing display of work ethic and good attitude that I have come across in a long time. Chris, Steve and Josh slogged doggedly through what turned out to be the job from hell without so much of a complaint, at least in my presence. In their own company they would have been right to commiserate about the terrible challenges this job entailed. There was nothing routine anywhere here on this install. Cindy and I are very grateful for the quality of both the work and the character of your crew.

I apologize to Chris to have been sleeping in my chair as he wrapped up at about 2 a.m. or so Wednesday morning and pulled out, I did not get the opportunity to thank him and Steve personally. Please pass this on to them and hopefully it will at least make up for some of that missed final thank you. I will look forward to my annual chimney service from now on instead of dreading it. Kudos, Tom and Cindy L. It was refreshing to find that this level of quality still exists in the young adults of today."
