The best through-the-roof stove-pipe choice depends on the roof shape, ceiling and attic layout, chimney system, and appliance requirements. For an attic installation, the AllFuel HST kit is the most complete listed option, but it is designed only for AllFuel HST Class-A chimney pipe. Selkirk offers support kits for particular ceiling or roof arrangements, while the silicone roof boot is a different kind of flashing product and should not be treated as a substitute for a listed chimney system. Confirm the appliance manual, chimney instructions, and local code before buying.

AllFuel HST Through The Attic Kit
Best for: A single-story flat- or vaulted-ceiling installation with an attic, when the selected chimney is AllFuel HST Class-A double-wall pipe. This is the most comprehensive listed option for buyers seeking an attic-through-roof package rather than a single flashing part.
The kit includes a black stove-pipe adapter, a square ceiling support box with trim, an attic insulation shield with storm collar, roof flashing with storm collar, and a chimney cap with spark arrestor. The listed support box can support up to 45 feet of chimney pipe. Roof-pitch and support-box-length selections are part of the product configuration.
Why it was selected: Its included components address several parts of a through-attic installation, and the product description states its intended setting and system compatibility.
Limitation: It is compatible with AllFuel HST Class-A chimney pipe only, not other brands of Class-A chimney. Pipe lengths are sold separately, so the kit alone does not complete the installation.
Selkirk Stainless Steel Ceiling Support Kit
Best for: Buyers whose installation calls for the listed Selkirk flat-ceiling support kit and who need several support and finishing components in one package. The supplied description identifies it as a support kit for venting stoves, fireplaces, and furnaces.
The package includes a round top, storm collar, flashing, attic insulation shield, finish support, and smoke-pipe adapter. The listing describes stainless steel construction and reinforced parts. Those components make it a more complete support package than a standalone roof boot.
Why it was selected: It directly addresses ceiling support and roof-penetration components, which are central considerations when routing a chimney through a roof.
Limitation: The supplied product details do not specify all dimensions, roof-pitch limits, or compatibility with other chimney brands. Check the product documentation and the exact chimney-system requirements before choosing it.
Selkirk 6T-PCK Pitched Ceiling Support Kit
Best for: A buyer planning a Selkirk installation where the specified configuration calls for pitched-ceiling support or a lateral chimney connection. The listing says the kit can be used with an insulated tee as an interior or exterior support in a system with a lateral connection.
Included components are a round top, storm collar, roof support package, finish collar, and smoke-pipe adapter. The listed braces fasten to the wall below the plate for chimneys that pass through a wall. That detail makes it relevant to certain wall-penetrating layouts, not just a straight vertical route through a ceiling.
Why it was selected: It describes a distinct support arrangement and includes roof-related parts, giving buyers a product to compare with a flat-ceiling kit.
Limitation: The listing describes a specific use with an insulated tee and lateral connection. Do not assume it is appropriate for every pitched roof or every chimney brand; verify the full installation instructions.
Selkirk Metalbestos 206621
Best for: Buyers who already have the exact part number and can confirm from manufacturer documentation that this item fits their existing Selkirk Metalbestos system. The provided listing identifies the brand and model number, and gives an item weight of 26 pounds.
Why it was selected: It is a Selkirk Metalbestos product in a set focused on through-roof stove and chimney installations. However, the available product information does not establish what component it is, what dimensions it has, or how it is installed. Treat the model number as a starting point for verification, not as proof of fit.
Limitation: The supplied details do not describe its function or compatibility. Avoid choosing it based only on its brand or weight; confirm the part description, diameter, and system instructions before purchase.
#6 Metal Roof Pipe Flashing Boot
Best for: Buyers evaluating a roof-penetration boot for a pipe with a 5- to 9-inch outside diameter, provided the application and installation requirements permit this type of flashing. The product description says its silicone can be trimmed to fit within that diameter range.
The boot has a square aluminum base and silicone flashing. Its listed temperature range is -100°F to 450°F, and the description says the material resists UV exposure, ozone, cracking, aging, and harsh weather. The larger square base is presented as a way to distribute fastening pressure and help seal against moisture.
Why it was selected: It offers a roof-sealing option that may be relevant to some metal-roof penetrations and clearly states a pipe-diameter range.
Limitation: The listing does not establish that this boot is an approved flashing component for a particular wood-stove chimney. It is not a complete chimney, support, or through-attic kit. Confirm the chimney manufacturer’s required flashing and clearances before using it.
Buying Guide: How To Choose Through-The-Roof Stove Pipe
Is stove pipe the same as chimney pipe?
No. Stove pipe commonly refers to the connector pipe between a stove and a chimney system. The roof-penetrating portion typically involves a chimney system designed for that use, along with the specified support, flashing, and clearances. Do not assume ordinary connector pipe can continue through a ceiling, attic, or roof. Follow the appliance and chimney manufacturers’ instructions and applicable local codes.
Which kit matches a flat or pitched roof?
Start with the support kit’s stated application, not only the roof shape. The AllFuel HST kit is described for a flat or vaulted ceiling with attic space and offers roof-flashing selections for roof pitch. The Selkirk pitched-ceiling kit describes use with an insulated tee and lateral connection. A flat-ceiling support kit is not automatically interchangeable with a pitched-ceiling kit.
Why does chimney-system compatibility matter?
Chimney components are designed to work as a system. The AllFuel HST listing explicitly limits compatibility to AllFuel HST Class-A double-wall chimney pipe. The Selkirk listings also require buyers to verify system fit from the product instructions. Do not mix parts from different brands or product lines unless the manufacturers explicitly permit that combination.
What components should a through-roof kit include?
Compare the package contents with the installation plan. Depending on the system and layout, relevant parts may include a ceiling support box or support plate, attic insulation shield, roof flashing, storm collar, finish trim, chimney cap, and stove-pipe adapter. The required components vary by system. Some kits exclude the chimney lengths needed to reach the roof and extend above it.
How should I check pipe diameter and roof details?
Confirm the chimney’s specified diameter and the outside diameter required by each component. Also check roof pitch, ceiling type, attic access, and whether the route is vertical or involves a lateral connection. For the silicone boot listed here, the stated fit range is 5 to 9 inches outside diameter, but that range alone does not confirm suitability for a stove chimney.
When should I consult an installer?
Get qualified installation guidance if you are unsure about clearances, framing, chimney height, roof flashing, support requirements, or local code. A roof penetration must be planned as part of the complete chimney installation. Product descriptions alone cannot determine whether a specific configuration is safe or compliant for a particular home.
Frequently Asked Questions
Can stove pipe pass directly through the roof?
Do not assume it can. Use the chimney system and transition specified by the appliance and chimney manufacturers, including the required supports, clearances, and roof components.
Does the AllFuel HST kit include chimney pipe?
No. Its listing says chimney-pipe lengths are sold separately. It includes several support, flashing, adapter, and cap components.
Can I use the AllFuel HST kit with another chimney brand?
The product listing says it is compatible with AllFuel HST Class-A double-wall chimney pipe and cannot connect to other brands of Class-A chimney.
Is a silicone roof boot a complete stove-chimney flashing kit?
No. The listed boot is a roof-penetration flashing product. Its description does not identify it as a complete chimney kit or confirm compatibility with a specific stove-chimney system.
What should I verify before buying a support kit?
Check the chimney brand and model, pipe diameter, ceiling and roof configuration, roof pitch, package contents, and installation instructions. Confirm that the selected components are approved for the intended system and layout.
