Available sizes for through the roof wood stove pipe kits

A through the roof wood stove pipe kit works best when the diameter, height, and layout are matched to your stove from the start.

Therefore, the right size depends on your stove collar and the manufacturer’s venting requirements, not personal preference. When the chimney diameter matches your appliance, the system is more likely to keep a steady draft and perform as intended.

For many residential wood stoves, cabins, and similar home heating setups, a 6 inch chimney pipe is the standard choice for through-the-roof installations.
For larger stoves and higher-output appliances that need a wider flue path, our 8 inch chimney pipe range is the right option to review. However, a larger diameter should only be used when the stove specifications call for it, since oversizing the chimney can affect how your system drafts.

How a wood stove pipe through cathedral ceiling is installed

MANUAL INSTALLATION GUIDE

A through-the-roof chimney system follows a straightforward vertical path from the stove to the roof exit. Here’s an overview of how the system is structured and where the transition to class A insulated chimney pipe takes place:

1. The black stove pipe starts in the room and connects your stove to the support box.

2. At the ceiling level, the system transitions to class A insulated chimney pipe.

3. The insulated chimney then continues safely through the roof using the correct flashing and support components.

The flashing itself is chosen by the pitch of your roof, not by the pipe. Our guide on how the roof flashing and storm collar work shows how to measure that and what each part at the penetration does.

4. The chimney must finish at the proper height above the roof for safe draft and code compliance.

For step-by-step guidance, check our wood stove chimney pipe installation resources.

Quick tips before you order a through-the-roof chimney kit

1. Confirm your setup type, making sure your installation is truly a cathedral-ceiling or no-attic setup, since this directly affects the components required.

Wondering what a new chimney installation involves? The full guide sets out every step and part.

2. Do not confuse a black stove pipe with a class A chimney pipe. A stove pipe stays inside the room, while the insulated chimney system begins where the pipe passes through the ceiling.

3. Verify your measurements, checking the stove collar size, total chimney height, roof pitch, and the amount of chimney needed above the roofline before ordering.

4. Review roof flashing requirements, because using the wrong flashing for your roof pitch can lead to fit and weather-sealing issues.

Why roof and cathedral ceiling penetrations require a class A insulated chimney pipe

Any part of the chimney system that passes through a ceiling or roof must use a class A insulated chimney pipe, not a regular stove pipe.

A black wood stove pipe is used only inside the room to connect the stove to the support box, and must not pass through combustible construction.
A class A chimney pipe is the insulated system designed for roof and cathedral ceiling penetrations. It’s built to handle high temperatures while maintaining the required clearances from nearby materials.

In most through-the-roof installations, keep at least 2 inches of clearance between the chimney pipe and combustibles to protect the surrounding structure.

Our through-the-roof kits use UL103HT insulated chimney systems from the point where the vent leaves the room. UL103HT is the U.S. safety standard for high-temperature chimney systems used with wood stoves, meaning the pipe has been tested for the demanding heat levels produced during wood-burning operation.

This insulated design:

Helps protect the surrounding structure
Supports code compliance
Improves long-term safety and performance in homes, cabins, and other spaces where the chimney runs vertically through the roof

Running the chimney through a metal roof

A metal roof changes one thing about the install: the sealing. The pipe itself does not change. From the ceiling up you still need UL 103 HT-listed Class A insulated chimney pipe, because that is the only pipe rated to pass through a combustible roof structure. What a standing-seam or corrugated steel panel demands is a flashing that matches the panel profile and the pitch, plus a watertight collar, so you never get a leak at the one spot water loves to find.

Match the flashing to your roof pitch

Metal roofs come in a range of pitches and the flashing has to match the angle so it sits flat and sheds water. We stock three pitch bands: a flat roof flashing for low and flat roofs, starting at $240 in 6 inch diameter, a 1/12 to 6/12 pitch flashing for standard roofs, and a 7/12 to 12/12 pitch flashing for steep roofs. The wizard above picks the right one once you tell it your pitch.

On a ribbed or standing-seam panel, set the flashing base over the penetration, bed it in a high-temperature roofing sealant along the uphill and side edges, and fasten with gasketed screws. Leave the downhill edge to lap over the panel so water runs off the roof rather than under it.

Seal the top with a storm collar

Above the flashing cone, a storm collar clamps around the pipe and is sealed with a bead of high-temperature silicone. This is the part that stops rain tracking down the outside of the pipe and into the flashing. It is a small component that does a big job, and it is included in the matched kit so you are not left improvising on the roof.

Frequently asked questions about our wood stove pipe kits through the roof

Can a stove pipe go directly through the roof?

No. A single-wall stove pipe should not pass directly through the roof or ceiling.

The correct setup is to use the black stove pipe only inside the room, then transition to UL103HT class A insulated chimney pipe at the support box before the system passes through the ceiling and roof.

In other words, a wood stove pipe through the roof starts as an interior stove pipe at the appliance, then continues as an insulated chimney pipe through the structure and above the roofline.
What is included in your through the roof wood stove pipe kit?

Our wood stove pipe kits through the roof include the main parts needed to create a complete vertical chimney route from the stove to the roof exit, not just a few roof-penetration components.

Our setup includes:

- A chimney cap with spark screen;
- A roof flashing with storm collar;
- A ceiling or roof support box;
- A stove pipe adapter to class A pipe;
- A class A insulated chimney pipe;
- An adapter from stove to stovepipe;
- A black single-wall stove pipe used in the room.

The exact combination can vary depending on your stove size, ceiling height, and roof layout, but the structure of the system stays the same.

The logic is simple:
1. The black stove pipe connects the stove inside the room.
2. Then, the system transitions to UL103HT insulated chimney pipe where it passes through the ceiling and roof.
3. The support box carries the transition, the flashing and storm collar help weather-seal the roof penetration.
4. The chimney cap finishes the system safely above the roofline.
Is it better to vent a wood stove through the wall or roof?

In many homes, venting through the roof is the better option when the layout allows it. A straight vertical run usually:

- Creates stronger draft
- Helps smoke and flue gases move upward more efficiently
- Often gives you a simpler chimney path overall

Through-the-roof installations also tend to have fewer turns, which can support steadier airflow and make the system easier to clean over time.

That said, through-the-wall venting can still be the right choice in some situations, especially when an indoor vertical route is not practical or the stove is close to an exterior wall.

The best option depends on your:
- Room layout
- Ceiling structure
- Available chimney path.

For cathedral ceilings, open rooms, and installations with no attic above the stove, a through-the-roof chimney kit is often the better fit. If your layout is better suited to an exterior exit, you can check our wood stove pipe kits through the wall.
How do I choose the right through-the-roof chimney kit for my stove and ceiling height?

The right through-the-roof chimney kit depends on three main things:

- Stove collar size
- Total chimney height
- Roof conditions

1. Start with the stove outlet. The chimney diameter should match it, because using the wrong size can affect draft and overall performance.

2. Then measure the full vertical run, from the stove location to the roof exit, not just the visible section in the room.

Ceiling height, roof thickness, and the amount of chimney needed above the roof all affect the final setup.

3. Roof pitch matters too. The flashing must match the roof slope so the chimney can pass through the roof with the correct fit and weather seal.
How high should the chimney extend above the roof?

Use the 3-2-10 rule as the standard guide.

That means the chimney should extend at least 3 feet above the point where it passes through the roof and at least 2 feet higher than anything within 10 feet.
Do your wood stove pipe kits through the roof come ready to install?

Our goal is to provide a complete, matched kit for this installation path, while the exact components depend on size, ceiling height, and roof setup.

Rather than piecing together separate parts, you get a matched chimney system designed to work together from the room connection to the roof exit.

Still, you should confirm measurements and configuration details before ordering so the system matches your stove and structure.
Do cathedral ceiling chimney kits need regular cleaning and inspection?

Yes. Like any wood stove chimney system, a through-the-roof kit should be checked and cleaned regularly for safe operation.

Over time, soot and creosote can build up, especially during heavy heating-season use.

Regular inspection and cleaning:
- Help maintain proper draft
- Reduce fire risk
- Support long-term system performance
