Chimney Chase cover Replacement

Chimney chase cover replacement is one of our most popular services. The chase pan is the solid metal sheet that covers the top of a pre-fab, or metal chimney. 

The chimney ‘chase’ is the box, or body of the chimney that you see when you look at your chimney.

In the case of prefabricated chimneys, the outer box, or chase, is just for looks. It serves no purpose except for style. 

The top of the chase would be wide open to rain, snow, animals, wind and other elements, if you didn’t have a ‘Pan’ or metal cover.

The chase pan is usually made of galvanized steel, though it can be ordered in Stainless Steel.  

We have found that a properly installed, galvanized chase cover, will last for several decades. We don’t normally recommend Stainless Steel, but it’s available if you so choose.cover

Rain Pan for Pre- Fab

The rain pan for a metal chimney must be installed properly or it won’t last very long. 

Water is the enemy of the pan. If water sits on the pan, it will rust through eventually.

Most pans develop tiny pin holes as they rust. When water is sitting on the pan, the pinholes allow it to drip inside the chase. 

So it is important to install the chase pan with an built in slope. The slope allows the water to run off, just like your roof.

The inside of the chase is only wood and siding. It would be like letting a hose drip water inside your walls. 

It will cause all kinds of damage and possibly lead to black mold.

Chimney Chase Cover Rust

If you see rust trails or stains on the side of the chase, it means there is so much rust on top that it mixes with the rainwater and drips off.

If you see rust on the side of your chimney, it is time to replace the pan.
You can get by for a little while with a little rust, but the damage being done to your house inside the walls is happening where you can’t see it.

So put it off at your own risk.

If installed properly, a pan should give you 30 to 40 years (or even more) of trouble free service.

As long as it is installed properly, it will probably outlast several new roofs during it’s lifetime.

On the other hand, if your pan leaks because of improper design, installation, or rust damage, you could be doing massive damage to wood and sheetrock inside your house.

Check your insurance to see if they cover water damage from your chimney….they may not.

Chimney Chase Rain Pans - How We Got Here

A chimney chase cover, commonly referred to as a rain pan, is a vital component in modern chimney systems, particularly for prefabricated units. The history of these covers is closely tied to the evolution of prefabricated chimneys, which began gaining popularity in the mid-20th century as a more cost-effective and versatile alternative to traditional masonry chimneys.

Manufacturing of Chimney Chase Covers

The manufacturing process of a chimney chase cover starts with the selection of materials. The most common materials used are stainless steel, galvanized steel, copper, and aluminum. Stainless steel is highly favored for its durability and resistance to rust and corrosion. Galvanized steel, though less expensive, is prone to rust over time. Copper offers a unique aesthetic but is more costly, while aluminum is lightweight and rust-resistant but less durable compared to stainless steel.

Once the material is chosen, it is cut to the required dimensions. This is typically done using a combination of computer-aided design (CAD) and computer numerical control (CNC) machines, ensuring precision and consistency in size and shape. The standard shape of a rain pan is flat or slightly sloped, with a downturned edge or skirt to channel water away from the chimney. It also features a central hole to accommodate the chimney flue pipe.

After cutting, the edges of the material are hemmed or folded over to add strength and prevent sharp edges. In some cases, cross breaks (slight bends in the metal) are added to prevent water pooling. The final step in manufacturing is applying a finish, which might involve painting or coating to improve aesthetics and further resistance to the elements.

Installation of Chimney Chase Covers

The installation of a chimney chase cover is a crucial process to ensure proper protection of the chimney system from water and environmental damage. It typically involves the following steps:

  1. Measurement and Inspection: Before installation, accurate measurements of the chimney chase are taken to ensure the cover fits perfectly. The condition of the chimney, including the flue and surrounding roofing, is also inspected.

  2. Preparing the Area: The top of the chimney chase is cleaned to remove any debris, old caulking, or rust. This ensures a clean surface for a better seal.

  3. Fitting the Cover: The chase cover is then placed over the top of the chimney chase, aligning the central hole with the chimney flue.

  4. Securing the Cover: The cover is secured to the chase using screws or fasteners. It’s essential to ensure that the cover is snug and secure to prevent it from being dislodged by wind or other elements.

  5. Sealing: A high-quality, weatherproof sealant is applied around the edges of the cover and where the flue pipe exits. This prevents water from seeping into the chimney system.

  6. Final Inspection: After installation, a final inspection is carried out to ensure the cover is properly installed and there are no gaps or potential for leaks.

The introduction of prefabricated chimneys and the subsequent need for rain pans marked a significant advancement in residential and commercial building practices. These chimney systems provided a safer, more efficient, and cost-effective alternative to traditional masonry chimneys, making them a popular choice in modern construction. The chimney chase cover, or rain pan, is a key component in maintaining the integrity and longevity of these systems, protecting them from water intrusion and environmental damage.
