Custom Copper Chase Covers

The Copper Chase Cover covers the entire top of your chimney. Often used to cover chimney chase surrounds or brick masonry crowns, it fits over the top of the chimney like a shoe box cover fits the top of a shoe box. Copper chase covers provide beauty and lifetime protection to your home. Watch our Chase Cover Installation Video to see how it works and our Chase Cover Measuring Guide Video to learn how to measure for your new cover. Measuring is the most important part of ordering a custom cover as they are made custom and are non-returnable.

We can custom make any chase cover you can imagine, from 16"x16" all the way to 96" x 48". (Larger sizes will be fabricated with an overlapping splice — please call for a quote.)

The standard skirting / flashing is 3" with a drip edge. All seams are welded. Our standard metal thickness is 24 gauge.

Measuring For Your Custom Chimney Chase Cover

A chase cover fits over the top outside edge of your chase or brick chimney, similar to a shoe box top. It can have no holes one hole or multiple holes, and is custom fitted to your particular chimney or chase. Here's how to measure for a great fit:

Length and Width: When measuring for a custom fitted chase cover, it is important that all measurements are accurate to the nearest 1/8". Also, be sure to measure all four sides. Just because one side appears to be the same length as the other does not mean it is! Mortar joints in between the bricks may be slightly different sizes, causing uneven side lengths. Measure both long sides and use the longest measurement for the length. Then measure both short sides and use the longest measurement for the width. 1/4" should be added to both length and width to provide the necessary tolerance for fabricating your chase cover.

Hole Measurements: If you need a hole or holes for your flue pipe to come through the chase cover, you should measure the round pipe diameter and add 1/2". (For oval or square/rectangle liners, add 1/2" to each dimension.) This extra allowance is important. If the hole is too small, your pipe will not fit through the chase cover. The gap between the pipe and hole can covered with an optional storm collar (for rigid pipe), or sealed with a sealer (for clay tile).

Be sure to include the dimensions to the edge of each hole from all four sides of the chase cover, so that the hole can be placed correctly. If you want the hole to be centered, then no additional dimensions are needed. 

Collar Height: The standard collar is 2" to 3". The collar is rolled out with an overlap, spot welded, and siliconed for extra protection. For a square or rectangle hole that will have a clay tile flue liner protruding from it, you may want to make the collar the same height as the clay tile in order to install a single flue chimney cap. 

Skirt Length: The skirt length should be long enough to cover any exposed wood and allow fasteners to go through the skirt and into the structure behind it for security. Standard skirt lengths are around 3".

Drip Edge and Diagonal Creases: Two important, no charge options are the top diagonal creases and the 1/2" drip edge, added to the bottom of the skirt. The creases prevent water and snow from accumulating and the drip edges keep the water from falling directly onto your siding or brick. Only the length, width and number of holes determine the price of the cover.

 Storm Collar: Use the chart below under "Help & Documents" to select your storm collar size.
